    The invention relates to a gear comprising a ten-wheel body with a toothing, which consists of a sequence of teeth, wherein the number of gas velocities of the teeth has the value X, and a backlash-free Rädertrteb comprising two intermeshing toothed wheels.
    Backlash-free gear drives are usually realized by means of a gear arrangement, a so-called spitt gear. Such a gear arrangement is, for example, from that of the applicant originating «! WO 2005/090830 A1 discloses a gear for a backlash-free Stimradstufe with a hub, with a supported by the hub sprocket along an achenormalen dividing plane in two TeHkränze, namely in a hub-fixed collar part and a coaxially rotatably mounted relative to this ring ring, is divided, and with a hub surrounding the annular spring, which is supported with their mutually in the circumferential clearing ends integrally formed with the two partial wreaths, overlapping each other in the axial direction Stotzstegen, which are arranged in the circumferential direction of the ring gear one behind the other. The support web of a sub-rim passes through the other sub-rim in a passage opening with clearance in the circumferential direction and forms the support web of the sub-rim with the Durchtrtttsüffhung the passage opening limiting mounting stop for the other support web. The ring collar is secured axially on the hub, for example by means of a snap ring
    Based on this, it is the object of the invention to simplify this gear arrangement.
    This object is achieved, on the one hand, by the cogwheel mentioned above, in which each Nth tooth has, at least in part, a lower tooth rigidity compared to the remaining XN teeth, where N is a number selected from a range with a lower limit of 2 and an upper limit of X, in particular X / 2, or that a number of M teeth at least partially a lower tooth stiffness N2010 / 22400 24/09 2010 PR 13:17 [SE / EH NR 5525] 0005 25 13:18:30 24 -09-2010 6/29 ι ··· «·« φ · * * e ··· * «e # ι ·« «·» »* · * ···

    By at least partially it is meant that the teeth of the gear can also be divided, for example, two-part, ausgefQhrt, with a part of the respective tooth has the lower tooth stiffness compared to the rest of the tooth
    The advantage here is that the functionality of the bias above the ring spring, i. The so-called Ω-spring, is introduced into the gear itself, which can simplify the structural design and thus the assembly of Rädertriabes compared to the gear arrangement according to the prior art It is thus compared to the gear arrangement according to the prior art, a cost reduction realizable. In addition, the wear of the gear can be achieved in comparison with the gear arrangement according to the prior art is reduced, since the bias or Spielfreistellung no vsrdehbares gear that is rotated during operation relative to the main gear, is required Another advantage associated with the inventive Gear can be achieved, it can be seen that this can also be used as an intermediate between two other gears, the backlash can be minimized or eliminated in both meshing gear pairings on the intermediate. This is not feasible with the gear arrangement according to the prior art, since the bias can be set above the Ω - spring only on a backlash.
    According to a Ausfqhrungsvariante is provided, each N-th tooth or the M teeth consists of or consist of a material which has a lower compared to the material of the remaining X-N teeth or X-M teeth elastic modulus. It is thus realized a structurally simple way for the bending of the N-th teeth for play clearance during engagement in a toothing, since thus all the teeth of the toothing of the gear can remain unchanged with respect to their tooth geometry.
    On the other hand, it is also possible that, for the bendability of the Nth or M teeth, a maximum tooth width of each Nth tooth or of the M teeth viewed in the axial direction is smaller than a maximum tooth width of the remaining NX teeth or XM N2010 / 2240024 / 09 2010 FR 13:17 [SE / EH NR 5525] @ 006 .25 ·· 13:18:48 24-09-2010 7/29 • ···································· 3
    When viewed in the same direction With this embodiment, it is achieved that the individual tooth geometries can already be taken into account in the manufacture of the toothed wheel body with the toothing, in particular if the toothed wheel is produced by a sintering method in which a corresponding mold can be used ,
    Each Nth tooth or teeth may be at least partially made of a different material than the rest of the X-N teeth or X-M teeth. It is thus an embodiment of the gear possible in which the ble ble teeth are not or hardly weakened by the tooth profile is adjusted accordingly, and yet the SpieHreistellung is achieved.
    According to one embodiment variant, it is provided that each Nth tooth or the M teeth is or are at least partially formed by a metal sheet metal element which is or are connected to the gear body. The sheet metal elements have the advantage that they can turn made relatively thin, but they still have the required strength for a long service life of the gear. In addition, the MetaR sheet metal elements can be easily converted into the desired shape for the bendability. Due to the thin design of these teeth also the advantage is achieved that the teeth at set center distance between the gears and tension with the mating gear simultaneously through the larger tooth gap, which is created by cüe use of the sheet metal elements, concentricity error of the gear can be better considered without that the teeth of the two gears jam together. In other words, the requirements for dimensional accuracy of the gear can be reduced without sacrificing functionality.
    But it is also possible that each N-th tooth or the M teeth are at least partially made of a plastic or are, so that the teeth are easy to produce, for example by injection molding, whereby a corresponding cost reduction can be achieved.
    The N-th teeth or the M teeth preferably form a common insert element from the material different from the material of the remaining XN teeth or XM teeth, this insert element being connected to the toothed body, optionally the toothed wheel body having a groove in an end face, and Insert element at least partially disposed in the groove Is it so that the handling in the assembly of the gear is unified. Due to the arrangement of the groove, the N201002400 24/09 2010 FR 12:17 [SE / EM NR S52S] 0007, 25, 25 θ / 20 13:19:06 24-09-2010 e · e e • ·· 99 e »· · • eeeee • IS •» • ae »* * -4-
    Material composite can be improved, whereby the risk of detachment of individual teeth is reduced during operation. In addition, the groove also has the advantage of easier fitting of the insert element in the gear body.
    According to a Ausfqhrungsvariante this is provided that the teeth of the insert element offset from the X-N teeth or X-M teeth of the toothing of the gear body are arranged to form an unequal pitch. It is thus the effect of Spielfreisteilung supported by the Verbiegbarkelt the N-th teeth, so that the Verblegbarkett can be reduced and thus the N-th teeth can be made of a more rigid material, whereby the mechanical strength of the gear can be improved.
    But it is also possible that each N-th tooth or the M teeth have or have a different tooth geometry to the remaining XN teeth or XM teeth, so as to the Verbiegbarkelt and the top cover with the teeth of the meshing Ge-genzahnrades during engagement in to influence the gearing.

    1 to 5 show a first embodiment of a gear 1. The gear 1 has a gear body 2, which has on its radially outer peripheral surface a toothing 3 of teeth 4. The total number of teeth 4 is referred to in the context of the invention with X. The absolute value of teeth 4 is dependent on the size of the gear, so its diameter, as well as the tooth size and the tooth geometry, which is selected in dependence on the application of the gear 1. Since this is known from the prior art, reference is made to the relevant literature.
    The gear body 2 with the teeth 4 is preferably at least partially made by eklem sintering process, in particular consists of a sintered steel, whereby other materials, such as bronzes or brass, can be used or the gear body and the teeth 4 may at least partially consist of a VollmaAerial , produced for example by casting.

    In the illustrated embodiment of the toothed wheel 1, each second tooth 4 is designed to be shorter in the axial direction than a toothing width 5 of the toothing 3 in the same direction. In general, each N-th tooth 4 can be made shorter in the axial direction than the remaining XN teeth 4. Both the longer and the shorter teeth 4 are preferably made of the same material, in particular one-piece with the gear body 2. In this case, all the teeth 4 this material in this embodiment of the gear 1, the same profile.
    The gap created by the cusped teeth 4 in the axial direction in the course of the teeth 4 is at least partially filled with a second material, in the form of the tooth profile of the teeth 4. Thus, this results in a total number of a toothing width 5 , Those of the remaining XN teeth 4 at least approximately corresponds, so in this embodiment, the tooth width of the 5, the shortened teeth 4 immediately adjacent teeth 4. In principle, it is also possible that these two teeth 6, 7 composite teeth 4 in the axial Direction are also shorter or longer than the remaining XN teeth 4.
    The partial teeth 7 formed from the second material have a lower tooth stiffness than the remaining X-N teeth, each considered under the same environmental conditions
    The additional material for the N partial teeth 7 may be in particular a plastic, for example a PA, a PPS, a PEEK, a PET, a PE, a UHMW-PE, a PTFE, etc. Preferably, the plastics used are also fiber-reinforced, for example with Glass or carbon fiber. In any case, the plastic should adhere to the mechanical load of the teeth 4 during the meshing engagement mH of the teeth of a counter-wheel. The other material may also be a metal or a metal alloy, for example a non-ferrous metal, Al, Cu, a bronze.
    In principle, it is possible for the partial teeth 7 to be individually attached to the gear body 2, for example by direct injection or insertion into recesses of the gear body, in particular with an undercut, wherein the teeth may preferably have a shape complementary to the recess , and / or by gluing to the gear body. In the preferred embodiment of the invention, at least several, preferably all, partial teeth form an insert element 8. Such an insert element 8 is shown in FIG. 3. This insert element 8 has an annular body 9, on whose outer circumference the partial teeth 7 ange- N2010 / 22400 24/00 2010 FR 13:17 ISE / EH NR 5525) 0010 13:19:51 24-09-2010 11/29, 25 ····································································, which together with the partial teeth 6 of the gear body 2, as shown in FIG 2, each of an entire second tooth 4, or more generally an entire Nth tooth 4, results. For better clarity, FIG. 5 shows an exploded view of a detail of the toothing 3 of the toothed wheel 1.
    It should be mentioned that, although preferably all partial teeth 7 form a single, one-piece, for example by injection molded insert element 8, but it also possible within the scope of the invention to form a plurality of partial insert elements, which only a part of the partial teeth 7, for example SO% or 25% , exhibit.
    It should be further noted that the ring body 9 of the insert element 8 need not necessarily be circular, but that other geometric shapes, such as e.g. a square or a hexagon or an octagon are possible, although the circular shape gives advantages and is therefore preferred
    In the preferred embodiment of the gear 1 according to this embodiment, the gear body 2 of the gear 1 has a rangnut 10 or a recess in an end face 11 in the axial direction, in which the insert element 8, i. the ring member 9 is arranged and connected to the gear body 2, as shown in FIGS. 2 and 4. It is thus not only a better connection of the insert element 8 achieved with the gear body 2, but also that the insert element 8 with a greater wall thickness - viewed in the axial direction - can be performed, whereby its mechanical strength can be increased. Slides is advantageous in that the insert element 8 can not be projectingly arranged on the gear body 2 in the axial direction.
    In principle, the Einsatzalement 8 may be a separate component. However, there is also the possibility that the insert diamond is molded onto the gear body.
    As is apparent from FIGS. 3 and 4, there is also the possibility that the partial teeth 7 have a greater thickness in the axial direction compared to the ring body. It is thus possible that a larger proportion of a tooth 4 can be formed from the partial tooth 7 of the insert element 8, whereby the Zahnstaiflgkait can be adjusted within certain limits.
    It should be noted at this point that the shape of the teeth 4 and partial teeth 6,7 are not restrictive of the invention, but rather, after use, of the present invention. N2010 / 22400 24/09 2010 FR 13:17 [SE / EM NO 5525J @ 011 -8- 25 -8- 25 12/29 13:20:08 24-09-2010 • ·· Μ the purpose of the toothed wheel 1 Since the different tooth shapes are known from the prior art, this will be the case here not further elaborated.
    It can therefore be made with this embodiment of the gear 1, a so-called "split gear" that compared to the prior art consists of only two parts The task of play clearance In a backlash-free gear drive with at least one meshing further gear is thereby from the teeth of the insert element 8 is met.
    In order to reinforce the bias, if necessary, the insert element 8 can be arranged rotated by a predefinable angle value, for example selected from a range with a lower limit of 0.05 ° and an upper limit of 0.5 °, so that the partial teeth 7 are not aligned with the partial teeth 6 of the gear body. This results in an uneven pitch of the teeth 3, i. that the distances between the teeth are different in size.
    According to another embodiment, there is the possibility that the insert element 8 via an additional spring element, for example a plate spring, which is attached externally on the insert element 8 and in an annular groove of a hub of the Zahnradkör-pers 2 for receiving a shaft. Such spring elements are known from the prior art, for example, in the above-cited prior art shown The Elnsatzelement 8 can thus be pressed against the gear body 2, so that optionally can be dispensed with an adhesion of the insert element 8 with the gear body 2.

This embodiment of the gear 1 is similar to the above-described embodiment, in which each second tooth 4th at least partially by a tooth 4 or partial tooth 7 made of a different material. In representational embodiment, each second tooth 4 is formed by a metallic sheet metal element 12, in particular a spring steel. In general, every Nth tooth 4 may in turn consist of this sheet metal element 12, where N is selected as all variants of the invention. From a range with a lower limit of 2 and an upper limit of X, in particular X / 2, where X is the total number of teeth 4, and in this case the sum of the number of teeth 4 and the number of sheet metal elements 12. In particular, N may be used in all embodiments of the invention.

Thus, every second, or every third, or every fourth, etc., tooth 4 may consist of a tooth made of another material with a lower tooth rigidity or with a lower modulus of elasticity, in each case in comparison to the X-N remaining teeth 4.
    In the subject embodiment of the gear 1, a gear 1 is obtained with a threefold Oberdedomg. The sheet metal elements 12 assumes the above-described tension for clearance clearance.
    As can be seen in particular from Fig. 7, the sheet metal elements 12 are not centric, i. the center between two teeth 4, but offset by a predefinable value from the center, resulting from the desired tension and the shape of the sheet metal element 12, in particular a bent Endberefches 13 of the sheet metal elements, i. the extent of the bend.

    The sheet metal elements 12 are preferably fastened or anchored respectively in recesses 14 in the gear body. In principle, it is possible for the sheet members to be set in a sintered form before the powder for the gear body 2 is filled, but they are preferably attached thereto after the manufacture of the gear body 2.
    In principle, it is also possible to replace this sheet metal element 12 by elements made of plastic. However, the embodiment as metallic sheet metal elements 12 is the preferred.

    In this embodiment of the gear 1 is every second tooth 4 - it is in this embodiment of the gear 1 not every second tooth 4 is replaced by a tooth made of a different material at least partially - or generally every Nth tooth, held by a predefinable angle value held , This angle value can be selected from the above angle range. It is thus achieved that contact points 19,20 on a front tooth flank 21 or, a rear tooth edge 22 - viewed in the direction of rotation of the gear 1 - or contact areas of a tooth 4 are not on a common imaginary circle - as in the gear after the State of the art is the case that is shown in Fig. 8 in the neck - but on two separate imaginary circles. It is also achieved by this compared to the prior art modified tooth geometry with adapted division set a reduction or elimination of the Verdrehflankenspiels, wherein the mating gear, so the additional gear 16 retains its original shape.
    In a AusfOhrungsvariante to - as shown in FIGS. 10 to 12 - each second tooth 4, or generally every N-th tooth 4, in comparison to the remaining XN teeth 4 have a maximum tooth width 23, viewed in the axial direction smaller than a maximum tooth width 24 of the remaining NX teeth 4, ie each first tooth 4 viewed in the same direction With maximum tooth width 23,24 is meant that tooth width 23,24, which has the largest value in cross section due to the tooth shape and normally is formed in the region between the tooth flanks 21, 22, as shown in FIG. 11. The exact position of the maximum tooth width 23, 24 depends on the respective tooth shape.
    In this embodiment, all the teeth 4 are made of a special material, in particular a sintered material. The tooth stiffness is influenced here by the reduction of the tooth width 23 of each Nth tooth 4, wherein each Nth tooth 4 is one compared to the remaining XN teeth 4 has greater flexibility due to the reduced cross-section. The concrete example of FIGS. 10 to 12 shows a gear 1 with a triple top cover. In addition, in this embodiment variant, every Nth tooth can also be arranged as described above. Each Nth tooth 4 is set at the center distance with the mating gear, i. the additional gear 16 braced and compensated by its elasticity also auftre-tende Rundlauffehier. It also creates no backlash.

In this case, every second tooth 4 of the toothed wheel body 2 is slotted, the resulting recesses being filled with a plastic, so that every second tooth 4 is made the partial teeth 7 may in turn be used as separate elements in the slots and be connected to the partial teeth 6, be glued in particular, or be made by injecting a plastic compound into the slots, for which a corresponding shape can be used, which can also be embodied so that the partial teeth 7 are not aligned - viewed in the axial direction - are formed with TeiEzähnen 6. The non-aligned arrangement can also be realized with the separate partial teeth 7 used. It should be clarified with this embodiment that the Teiizähne 7 is not necessarily terminal, i. must be arranged beginning at the end face 11 of the gear body 2.
    According to a further embodiment variant of the toothed wheel 1, it is provided that the toothing 3 again has X teeth 4, wherein a number of M teeth at least partially have the lower tooth rigidity than the remaining XM teeth, where M is selected from a range with a lower limit of 1 and an upper limit of X-1 or an upper limit of X, provided that at least individual teeth are split, or all teeth have a different geometry.
    In general, in all embodiments of the invention, at least individual teeth 4 may also be designed in two parts, so that the teeth 4 only partially have the lower tooth rigidity.
    Thus, according to this embodiment of the toothed wheel 1, there is also the possibility that all teeth 4 have different tooth stiffnesses, at least partially, for example, all teeth 4 have a different geometry. It is within the scope of the invention also the possibility that the gear 1 consists of two Teilzahnrädem, wherein a Teüzahnrad of the plastic or the metal or the metal alloy, as above ausgefOhrt formed. Both partial gears have in this embodiment, the same number of teeth together form the teeth 4 of the teeth 3. The two partial gears can be used, for example, with N2010 / 22400 24/09 2010 FR 13:17 [SE / EM NR 5S25] ® »&rdq; 15 r25 13:21:17 24-09-2010 16/29 • ·· * ··· You can glued them together using a serration or using another suitable connection method.
    In addition, however, it is also possible for a different number M of teeth 4 with the lower tooth stiffness to be drawn out. It can therefore not only a periodically recurring number of teeth 4, as is the case with the variants with the N teeth, but also a non-periodically recurring number of teeth 4 at least partially Erflndungsgemäß be executed. For example, a tooth 4 with a higher tooth stiffness, the three adjacent teeth 4 with a lower Zahnstelflgkelt, the two adjoining these teeth 4 with a higher Zahnsteifig-keit, the subsequent tooth again with a lower tooth stiffness, etc. be executed , Due to the multitude of possible combinations resulting from this, their reproduction is despised. Ultimately, the interpretation of the gear 1 with the inventive toothing 3 u.a. also after the toothing of the meshing with the gear 1 gear.
    Incidentally, at least some of the above remarks on the N teeth, as they are also reproduced in the claims, also apply to this embodiment variant, so that a repetition is dispensed with.
    With the invention, over the tooth flexure associated with tooth stiffness, i. the tooth geometry, at a defined load, which results from the particular application of the gear 1, and / or the modulus of elasticity of the material used can be adjusted, the tension of the gear 1, i. the Spielfreisteilung be realized without an additional spring element by the functionality of the spring element is introduced into the teeth 4 of the gear 1. N, M or all teeth 4 can contribute to the tension. Alternatively or additionally, a one-sided smaller tooth space can be generated by a rotation of the teeth 4 or partial teeth 7 from the other compared to dam material of the gear body 2 other material by a predefinable angle. It is thus a certain torque (biasing torque) required to bend a tooth. During the load, the tooth can escape, whereby a jamming of the teeth can be prevented. Bai the embodiment with the sheet metal elements 12, these bend during operation, resulting in again a Verspannmoment. The tension can also be performed so that a small backlash is set.
