    The invention relates to a pulley having a base body, which has a hub on which a board is arranged, wherein the board is formed by a separate component from the main body, which is positively and / or non-positively connected to the base body via at least one connecting element, wherein the connecting element comprises a first and a second connecting element part, one of which is formed on the hub and one on the board.
    Furthermore, the invention relates to a belt drive with at least two pulleys.
    In addition, the invention relates to a method for positive and / or non-positive connection of a board with a main body of a pulley on the main body of the pulley, a hub is formed, on which the board is pushed, and the board via at least one connecting element connected to the main body is formed, wherein the connecting element is formed with a first connecting element part and a second connecting element part, one of which is formed on the hub and one on the board.
    Pulleys are known to be used in belt drives for torque transmission from one shaft to another shaft. For this purpose, between at least two belt wheels, one of which is arranged in each case on one of the shafts, a traction means, so a belt tensioned. The driven pulley transmits the torque to the non-driven pulley with the aid of the traction means. In order to prevent the traction means from migrating away from the belt pulley during operation, a so-called board is often used, which projects beyond the track of the traction means in the radial direction. If the board is not integrally formed with the body, it must be connected to the body. Frequently, the board is at least selectively welded to the base body. This process requires a separate manufacturing step that does not or hardly integrate in a production line of series or mass production of pulleys. This increases the manufacturing costs for the pulley.
    In the prior art, other methods for connecting a board with the main body of a pulley have been described with which a simple, inexpensive and variable production and installation of the board should be possible.
    Thus, for example, DE10 2014 201 565 A1 describes a method for fastening a flanged wheel to a belt drive after which the flanged wheel is pushed in the axial direction onto a collar of a pulley and then a section of the board is rolled by rolling into a groove of the federal government.
    DE 10 2005 018 581 A1 describes a toothed belt pulley with a flanged disc attached thereto, which is designed as an essentially flat sheet metal disc with an internal toothing and is pressed onto the toothed belt pulley with the internal toothing.
    From EP 2 128 496 A2, a toothed belt wheel for a toothed belt drive with a pot-shaped or bell-shaped main body and at least one flange, which is designed as a separate part known. For connection of the board with the main body are in addition to welding u.a. also called compression and caulking as methods.
    Furthermore, it is known to attach flanged wheels by screwing or clipping. The assembly effort here, however, is considerable.
    It is the object of the invention to provide a way of connecting a board with a main body of a pulley.
    The object is achieved with the pulley mentioned above in that the first connecting element part is cam-shaped and the second connecting element part is formed by at least one recess.
    Further, the object is achieved with the aforementioned belt drive, in which at least one of the belt wheels is designed according to the invention.
    In addition, the object is achieved with the initially mentioned method, according to which the first connecting element part is produced in the shape of a cam and the second connecting element part as at least one recess, further that the cam-shaped first connecting element part is inserted into the recess, and then the board is twisted in the circumferential direction, so that the positive and / or non-positive connection is formed between the cam-shaped first connecting element part and the second connecting element part.
    The advantage here is that the connection of the board with the main body of the pulley by simple movements, namely the pushing of the board on the hub of the body and the subsequent twisting of the board can be made in the circumferential direction. Thus, this connection method is easier to integrate into an existing production line for pulleys, which can be made more cost-effective, since no additional manipulation of the pulley is required, with the pulley is brought out of the production line in a welding area. The simple non-positive and positive connection between the body and the board may optionally be solved again by the board is rotated in the opposite circumferential direction. It can thus be simplified assembly and disassembly of the belt. In addition, the at least one connecting element can be produced simply by means of sintering technology. By optionally existing plastic deformation of the cam-shaped first connecting element parts during rotation of the board, which is provided in particular in the simplest embodiment of the pulley, the positive and / or positive connection of the board can be improved with the main body of the pulley.
    According to one embodiment of the pulley can be provided that the second connecting element part is formed by two juxtaposed recesses, wherein the positive and / or non-positive connection with only one of the two recesses can be formed and by means of the second recess of the board can be pushed onto the hub , For the preparation of the compound of the board is twisted in the circumferential direction, so that the cam-shaped connecting part is spent to form the positive and / or non-positive connection in the second recess.
    It is thus a higher degree of security against unintentional release of the board accessible from the main body of the pulley. After the connection is made via only one of the two recesses of the second connecting element part, thus the other recess remains free during operation of the pulley. If the recess is formed as a breakthrough, this can also be used to lubricate the pulley, whereby a corresponding additional benefit can be achieved with the pulley.
    According to a preferred embodiment variant of the belt wheel, it can be provided that the second connecting element part has an at least approximately W-shaped cross section viewed in the axial direction. It can thus be simplified, the twisting of the board by the cam-shaped connecting element part can be easily moved from one into the other recess part.
    For easier sintering production of the base body and the Bordes preferably the cam-shaped first connecting element part on the hub of the base body and the further connecting element part are formed in the board.
    It may further be provided that in a circumferential direction of the connecting element then at least one further connecting element is out forms, which aulweist a third and a fourth connecting element part and with which the board is frictionally connected to the base body. Due to the additional non-positive connection, the safety of the connection between the main body of the pulley and the board can be improved.
    It is advantageous if the third connecting element part is cam-shaped, since this geometry of the connecting element part simplifies the rotatability of the rim in the circumferential direction.
    The fourth connection element part may be formed by a further recess which extends in the circumferential direction over a greater length than corresponds to a width of the third connection element in the same direction. It can thus be made on the one hand an exclusively non-positive connection between the board and the main body of the pulley, whereby also the rotatability of the board can be improved in the circumferential direction. On the other hand, due to the different geometry of the fourth connecting element part in comparison with the second connecting element part, the mountability of the board can be simplified by the incorrect placement of the board on the hub of the main body of the pulley can be easily avoided. The second connecting element part can therefore also be used as an assembly aid for the correct adjustment of the board on the hub.
    To further improve these effects, it can be provided that the further recess of the fourth connection element part has an at least approximately rectangular or trapezoidal cross-section viewed in the axial direction.
    To improve the non-positive connection of the board with the main body of the pulley can be provided that on a side wall of the further recess of the fourth connection element part, between the and the first connection element part of the first connection element in the circumferential direction, the third connection element part is arranged, one in the further recess protruding projection is formed. During the twisting of the rim in the circumferential direction, this projection slides on an edge of the cam-shaped third connecting element part until the frictional connection is formed, wherein this is limited to a smaller surface area due to the relatively small surface of the projection.
    As described above for the first connecting element, the third connecting element part may be formed on the hub of the main body and the fourth connecting element part in the board for easier sinterability manufacture of the board and the main body of the pulley.
    It can further be provided that a part of the first connecting element part is arranged overlapping an axial end face, whereby an improved axial securing can be achieved by a frictional connection can be formed via the abutting surfaces of the first connecting element part and the board.
    According to one embodiment variant of the method it can be provided that in the circumferential direction of the connecting element then at least one further connecting element is formed with a third and a fourth connecting element part, wherein the third connecting element part is cam-shaped and the fourth connecting element part is produced in the form of a recess, and that the board is connected via the other connecting element frictionally connected to the main body of the pulley by the rotation of the board in the circumferential direction. Reference should be made to the preceding comments on this further connection element.
    For a better understanding of the invention, this will be explained in more detail with reference to the following figures.

    Figure 1 is a pulley with body and board in the unconnected state in an oblique view.

    Fig. 4 shows the pulley of Figure 1 in the connected state and in side view.
    5 shows a belt drive in side view;
    Fig. 6 shows a section of a variant of the pulley cut in axial view.
    By way of introduction, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, the disclosures contained in the entire description can be mutatis mutandis to the same parts with the same reference numerals or component names. Also, the location information chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and to be transferred to a new position analogously to the new situation.
    In Fig. 1, a pulley 1 in the form of a toothed belt wheel is shown in an oblique view. This toothed belt wheel 1 comprises a main body 2 and a board 3 (thrust washer element), which is formed in this embodiment as flanged wheel. The board 3 is arranged laterally on an end face and on a hub 4 of the main body 2.
    The wheel body 2 has a toothing 5 on a lateral surface. This toothing 6 is formed by teeth 6, between which tooth spaces 7 are formed. The geometry of the teeth 6 and the geometry of the tooth gaps 7 are designed so that it can be engaged with a toothed belt. Since toothed belt wheels 1 are already known from the state of the art with regard to their geometric configuration, further discussion is unnecessary at this point and the person skilled in the art should therefore refer to the relevant literature.
    The base body 2 and / or the board 3 are preferably made of sintered components, wherein the sintering - as known - the mixing of a sintering powder optionally with various additives, such as lubricants, etc. to facilitate the Entformbar-speed of the sintered component, further pressing the Sintered powder in a press die to a green compact and the sintering of the green body at sintering temperature, which depends on the metal powder or metallic powder used comprises. The sintering powders are usually metal powders or metallic powders for sintered alloys, and may also be pre-alloyed powders. After sintering, re-densification and / or calibration of the sintered component is optionally carried out in order to increase the dimensional accuracy.
    As sintering powder or sintered alloy powder, for example, a sintered iron or a sintered steel or powder according to the standard SINT E 35, SINT E 36, SINT E 39, or other known from the prior art sintering (alloy) powder can be used.
    Although the sintering technology of the pulley 1 is preferred, it is in principle possible to manufacture this pulley 1 with other manufacturing methods, for example by casting or injection molding techniques. However, the sintering technology offers a possibility for simplified manufacture of the pulley 1, so that no mechanical post-processing is required if necessary.
    Although in the figure, the pulley 1 is shown in the form of a toothed belt wheel, the invention is not limited thereto. Rather, the invention relates to pulleys 1 per se, so for example, pulleys with a smooth or roughened lateral surface at least in the belt track. Such pulleys thus have no teeth in this area. Further, the pulley 1 may in principle also be provided for a belt having a V-shaped cross section or a ribbed belt, although the necessity of arranging the board 3 does not arise to the same extent here.
    It should be noted at this point that the pulley 1 may also have another board, which can be arranged on a second end face of the base body 2. The belt track on the lateral surface can therefore be bounded on both sides by a respective board 3. For this further board, the statements in this description can be applied, so that this and the base body 2 can be formed in this area as described below.
    The board 3 is made as a separate component, so therefore a connection of the board 3 with the main body 2 of the pulley 1 is required. For this purpose, at least one connecting element 8 is provided, which is better seen in FIG. 2 and in particular in FIG. 3. These figures show the pulley 1 with not yet connected board. 3
    As can be seen from these figures, distributed over the circumference of the pulley 1, in particular distributed regularly, preferably a plurality of these connecting elements 8 are arranged. The exact number depends on connecting elements 8 depends primarily on the diameter of the pulley 1 and the desired connection strength. Preferably, all of these connecting elements 8 are identical.
    With the at least one connecting element 8 between the board 3 and the main body 2 of the pulley 1 is a non-positive and / or positive, in particular a positive and positive, made connection. For this purpose, the connecting element 8 has a first connecting element part 9 and a second connecting element part 10.
    The first connecting element part 9 is preferably arranged on the hub 4. The hub 4 is formed in the illustrated embodiment as an annular web, which is arranged projecting on the end face of the main body 2 of the pulley 1 and about this in an axial direction 11 (Figure 1). Preferably, the hub 4 viewed in the radial direction below the belt track, so the gearing 5 of the embodiment arranged.
    The first connecting element part 9 is designed as an at least approximately cam-shaped or knob-shaped projection which projects beyond the hub 4 in the radial direction. In particular, the first connecting element part 9 is cam-shaped.
    The first connection element part 9 has a maximum height 12. The height 12 is dimensioned from a surface of the hub 4 to the maximum dimension of the first connecting element part 9 in the radial direction. Furthermore, the first connecting element part 9 has two side surfaces 14, 15 and a vertex 16 or a cover surface between the two side surfaces 14, 15. In other words, the first connecting element part 9 in the preferred embodiment can also be seen in the form of a tooth.
    However, the first connection element part 9 may also have a cross-sectional shape (viewed in the axial direction 11) other than that shown in the figures. For example, the first connection element part 9 can have a semicircular or a trapezoidal cross-sectional shape, but round cross-sectional shapes or cross-sectional shapes with rounded edges are preferred.
    Preferably, the first connecting element part 9 extends over the entire width of the hub 4 in the axial direction 11.
    The second connecting element part 10 is preferably formed on or in the board 3. It is formed by two juxtaposed recesses 17, 18 in the board 3. At least one of these recesses 17,18 forms the contour of the first connecting element part 9 of the connecting element 8 at least partially, so that a positive and optionally non-positive connection between the first connecting element part 9 and the second connecting element part 10, and thus a positive and optionally non-positive connection Bords 3 is formed with the base body 2.
    Although the other of the two recesses 17, 18 can also reshape the contour of the first connecting element part 9, this recess 17 is larger in its cross section in the axial direction 11 (FIG. 1) than the corresponding cross section of the first connecting element part 9 Thus, no connection between the board 3 and the main body 2 of the pulley 1 made on this recess 17. The cross section of this recess 17 is dimensioned so that the board 3 can be pushed onto the hub 4 of the base body 2. It is therefore possible that the recess 17 may also have a different cross-sectional shape than the first connecting element part 9 in order to fulfill its function. However, it is preferable if this recess 17 also at least approximately reshapes the contour of the cross section of the first connecting element part 9, since this makes it easier to avoid tilting of the rim 3 when pushed onto the hub 4.
    Only for the sake of completeness it should be noted that the recess 17, with the pushing of the board 3 on the hub 4 in Fig. 3 is the respective right of the two recess 17,18 of the second connector element part 10. However, this arrangement depends only on the direction of rotation of the board 3, with which it is connected to the main body 2 of the pulley. It can therefore also the reverse arrangement of the two recesses 17, 18 are provided to each other.
    After extending in the illustrated embodiment, the first connecting element part in the radial direction to the outside, consequently, the recesses 17,18 extended starting at a pointing to the hub 4 end face 19 of the board 3 in the radial direction to the outside.
    A maximum depth 20 of the recess 17 for the axial sliding of the rim 3 on the hub 4 is greater than the maximum height 12 of the first connecting element part 9 and is greater than a maximum depth 21 of the recess 18 for the formation of the form and optionally adhesion between the board 3 and the main body 2 of the pulley. 1
    The maximum depth 21 of the recess 18 is slightly larger, equal to or slightly smaller than the maximum height 12 of the first connector element part 9. The term "slightly" is understood to mean that the dimension is such that the positive connection between the recess 18 and the first connecting element part 9 is formed.
    Next, a width 22 of the recess 17 is greater than a width 23 of the first connecting element part 9 and a width 24 of the recess 18. The width 24 of the recess 18 is slightly larger, equal to or slightly smaller than the width 23 of the first connector element part 9. With regard the term "minor" should be referred to above definition.
    The widths 22-24 are measured in a circumferential direction 25 (FIG. 2) of the board 3.
    The two recesses 17, 18 of the second connecting element part 10 are preferably designed as openings in the axial direction 11 (FIG. 1) through the board 3. However, there is also the possibility that the recesses 17, 18 of the second connecting element part 10 are formed only from depressions in the board 3. In this case, the recesses 17,18 are formed on the surface of the belt 3 facing the belt track.
    As stated above, the two recesses 17,18 in the circumferential direction 25 (Fig. 2) are formed adjacent to each other in the board 3. The two recesses 17, 18 are separated from each other only by a web 26. This web 26 is preferably designed cam-shaped or tooth-shaped or in the form of a wave crest in the axial direction 11 (FIG. 1), whereby the sliding over of the first connecting element part 9 from the recess 17 into the recess 18 of the second connecting element part 10 is simplified. A maximum height 27 of this web 26 in the radial direction is smaller than the maximum depth 20 of the recess 17 and smaller than the maximum depth 21 of the recess 18 of the second connecting element part 10th
    The web 26 directly adjoins the recesses 17, 18 of the second connecting element part 10.
    The web 26, like the first connecting element part 9, has two side surfaces which merge into a vertex or a cover surface. In each case one of the two side surfaces forms in each case a boundary for the recess 17 and the recess 18 of the second connecting element part 10. The side surfaces are ge gene inclined to the radial direction, as can be seen from Figures 2 and 3. A slope of these side surfaces is preferably smaller than a slope of the side surfaces 14,15 of the first connector element part 9. This embodiment can be used in particular when the release of the board 3 from the main body 2 of the pulley 1 is to be provided. If the board 3 inextricably linked to the main body 2 of the pulley 1, it can also be provided that the side surface of the web 26, which faces the recess 18 of the second connecting element part 10, has a greater slope than the side surface 14 of the first connecting element part 9. The steepness of the respective surfaces is considered in relation to the inclination to the radial direction. In other words, the side surfaces 14, 15 of the first connecting element part 9 may have a smaller angle to the radial direction than the side surfaces of the web 26.
    There is also the possibility that between the belt track of the pulley 1 and the board 3, an axial stop for the board 3 is formed, with which it can be ensured that the board 3 only up to this axial stop on the hub 4 of the main body 2 of the pulley 1 can be postponed. The axial stop may be formed as a further annular web, which projects beyond the hub 3 in the radial direction. However, it is also possible for only parts of an annular web extending over 360 ° to be formed.
    According to a preferred embodiment of the belt pulley 1, it may be provided that the second connecting element part 10 has the contour of an at least approximately W-shaped cross-section viewed in the axial direction 11 (FIG. 1), which consists of the sequence of the recess 17, the web 26 and the recess 18 in the circumferential direction 25 (Fig. 2).
    It can further be provided that in the circumferential direction 25 (FIG. 2) to the connecting element 8 then at least one further connecting element 28 is formed which has a third and a fourth connecting element part 29, 30 and with which the board 3 frictionally with the main body 2 of the pulley 1 is connected.
    Preferably, a plurality of further connecting elements 28 are distributed over the circumference of the pulley 1, in particular regularly distributed, arranged. It is further preferred if, in the circumferential direction 25 (FIG. 2), first and second connecting elements 8, 28 are arranged alternately, and in particular distributed regularly over the circumference.
    The number of further connecting elements 28 depends in particular on the number of connecting elements 8, wherein preferably the same number of connecting elements 8 and further connecting elements 28 are arranged or formed.
    Preferably, the third connecting element part 29 is arranged or formed on the hub 4. It is further preferred that the fourth connecting element part 30 is arranged or formed on the board 3.
    Although not preferred, the reverse arrangement is also possible, that is to say that the third connecting element part 29 is formed on the board 3 and the fourth connecting element part 30 is formed on the hub 4. The same applies to the first connecting element part 9 and the second connecting element part 10 of the first connecting element 8.
    In addition, a mixed arrangement is possible, that is, a part of the first connecting element parts 9 and / or a part of the third connecting element parts 29 are formed on the hub 4 and the rest on the board 3. Accordingly, a part of the second connecting element parts 10 and / or the fourth connecting element parts 30 are arranged on the board 3 and the remainder on the hub 4.
    The third connecting element part 29 is designed as an at least approximately cam-shaped or knob-shaped projection which projects beyond the hub 4 in the radial direction. In particular, the third connecting element part 29 is cam-shaped.
    The third connection element part 29 has a maximum height 31. The height 31 is dimensioned from a surface of the hub 4 to the maximum dimension of the third connecting element part 29 in the radial direction. Furthermore, the third connecting element part 29 has two side surfaces 32, 33 and a vertex 34 or a cover surface between the two side surfaces 32, 33. In other words, the third connecting element part 29 in the preferred embodiment can also be seen in the form of a tooth.
    However, the third connection element part 29 can also have a cross-sectional shape (viewed in the axial direction 11, FIG. 1) other than that shown in the figures. For example, the third connecting element part 29 can have a semicircular or a trapezoidal cross-sectional shape, but round cross-sectional shapes or cross-sectional shapes with rounded edges are preferred.
    Preferably, the third connecting element part 29 extends over the entire width of the hub 4 in the axial direction 11.
    It is further preferred if the third connecting element part 29, viewed in the circumferential direction 25 (FIG. 2), has a larger maximum width 35 than the first connecting element part 9.
    The fourth connection element part 30 is formed by a further recess 36, which extends in the circumferential direction 25 (FIG. 2) over a greater length 37 than corresponds to the width 35 of the third connection element 29 viewed in the same direction. The length 37 of the recess 36 is at least so large that upon rotation of the board 3 in the circumferential direction 25, the first connecting element part 9 of the first connecting element 8 can be moved from the recess 17 into the recess 18 of the second connecting element part 10.
    The further recess 36 of the fourth connection element part 30 preferably has an at least approximately rectangular or trapezoidal cross-section viewed in the axial direction 11 (FIG. 1). However, other cross-sectional shapes of the fourth connecting element part 30 are also possible.
    The fourth connecting element part 30 is formed in particular by only a single further recess 36.
    It is further preferred if only a frictional connection is formed between the third connecting element part 29 and the fourth connecting element part 30.
    The further recess 36 of the fourth connecting element part 30 is preferably formed as an opening in the axial direction 11 (FIG. 1) through the board 3. However, there is also the possibility that the further recesses 36 of the fourth connecting element part 30 is formed only from recesses in the board 3. In this case, the further recesses 30 are formed on the surface of the belt 3 facing the belt track.
    According to a further embodiment variant of the belt wheel 1, provision can be made for the third connecting element part 29 to be arranged on one side wall 38 of the further recess 36 of the fourth connecting element part 30, between the first and the first connecting element part 9 of the first connecting element 8, in the other Recess protruding projection 39 is formed. This projection 39 may be formed by an inclination of the side wall 38 of the further recess 36 for forming an undercut in the further recess 36. In particular, this projection 39 is located at the transition between the hub 4 pointing end face 19 of the rim 3 on the side wall 38 of the recess. It is further preferred if this projection 39 is formed in cross-section at least approximately like a pin or at least approximately pointed (viewed in the direction of the axial direction 11, Fig. 1). The tip can also be provided with a rounding.
    As already mentioned above, branches the Fig. 2 and 3, the pulley 1 in a position in which the board 3 is indeed already placed or pushed onto the hub 4 of the body 2, but still no connection between the board 3 and the body 2 is formed.
    In Fig. 4 the board 3 is shown connected to the main body 2 of the pulley 1.
    To produce the connection of the positive and / or non-positive connection of the board 3 with a base body 2 of the pulley 1, the board 3 is pushed onto the hub 4. In this case, the first connecting element part 9 of the first connecting element 8 is inserted into the recess 17 of the second connecting element 8, as shown in Fig. 2 or 3. Thereafter, the board 3 is rotated in the circumferential direction 25, so that the (cam-shaped) connecting element part 9 of the first connecting element 8 for forming the positive and / or non-positive connection in the second recess 18 is spent, as shown in Fig. 4.
    If the second connecting element 28 is provided, the third connecting element part 29 is thereby moved inside the further recess 36 of the fourth connecting element part 30 in the direction of the side wall 38 of the further recess 36 until the (cam-shaped) third connecting element part 29 bears against this side wall 38 and a frictional connection between the side wall 38 and the third connecting element part 29 is formed. It is possible, in particular if on the side wall 38 of the projection 39 is formed, that between the side wall 38 (or the projection 39) and the third connecting element part 29 a positive connection is additionally formed, if the adjacent part of the side wall (in particular the projection 39) presses into the third connecting element part 29.
    In all embodiments of the pulley 1, the regions of the connecting element 1, which form the positive and non-positive connection between the board 3 and the main body 2 of the pulley 1, viewed in the radial direction formed superimposed. The same applies to the areas of the possibly existing further connecting element 28, which form the non-positive (and optionally form-fitting) connection.
    For the sake of completeness, FIG. 5 shows a simple belt drive 40, in particular a belt drive. This has at least two belt wheels, between which and the belt wheels wrap a traction means 41, i. a belt is stretched. At least one of these pulleys is formed by the pulley 1 according to the invention. But it can also be formed by a respective pulley 1 according to the invention, both pulleys. It is further possible that the belt drive 40 has more than two belt wheels, wherein at least one of these further belt wheels is formed by a belt wheel 1 according to the invention.
    In the simplest embodiment variant of the belt wheel 1 it can be provided that the first connecting element 8 has the cam-shaped first connecting element part 9 and as the second connecting element part 10 only one recess 17. In this embodiment, the first connecting element part 9 is brought to bear against a radially lower end face of the recess 17 by the rotation of the rim 3 in the circumferential direction 25 as in the other embodiments. As a result of the further rotation of the rim 3, an at least partially plastic deformation of the first connecting element part 9 takes place. As a result, the first connecting element part 9 fits better against the radially inner end face of the recess 17, whereby the non-positive and / or positive connection is formed. According to one embodiment, the recess 17 may have an at least approximately trapezoidal cross-section so that the first connecting element part 9 runs onto the said end face.
    According to a further embodiment variant shown in FIG. 6, it can be provided that only a part of the first connecting element part 9 is plastically deformed when connecting the rim 3. The remaining part of the first connecting element part 9 can then be arranged overlapping an axial end face 42 of the board 3. It can therefore be provided that the first connecting element part 9 is not arranged as in the preceding embodiments entirely in the radial direction below the radially inner end face of the recess, but that a part of the first connecting element part 9 is arranged offset in the axial direction to this end face. It should be noted, however, that this can also be provided in all other variants of the belt pulley 1.
    Further, it can be provided in all other embodiments of the pulley 1, that the first connecting element part 9 is at least partially plastically deformed in the manufacture of non-positive and / or positive connection between the board 3 and the main body 2 of the pulley 1, in particular permanently plastically deformed becomes.
    The embodiments show or describe possible embodiments of the pulley 1, wherein it should be noted at this point that combinations of the individual embodiments are possible with each other.
    For the sake of order, it should finally be pointed out that for a better understanding of the structure of the pulley 1, this was not necessarily shown to scale.
