    Description: [0001] The invention relates to a roll of a fiber web machine, the [0002] - an axle construction, by which the roll is intended for carrying, [0003] - a jacket provided around the axle construction, [0004] - one at least at one end of the Mantels provided Achshülse, which is arranged from its opening around the axle and provided on the axle construction for locking, - is associated with a seal between the shaft sleeve and the axle construction.
    The prior art knows in connection with press rolls of Faserbahnma-machines sleeves on Achszapfenhals on which move the ends of the band mantle. The ends rotate with the band jacket in the circumferential direction of the roller. In addition, they can still move in the axial direction while tensioning the band jacket in the longitudinal direction. On the sleeve, the bearing of the end ring of the band jacket is arranged. With the help of the sleeves and the eccentricity of the roll end can be caused.
    In the attachment of the sleeve at the neck of the axle is known in the art to use a separate wedge. The wedge positions the sleeve in the direction of rotation and in the axial direction to the right place. In addition, the sleeve is locked in place with screws. The seal between the sleeve and the axle requires a separate gasket cover. Due to the eccentricity, the sleeve is thin at the location of the wedge. As a result of this, shape changes normally can not be avoided, e.g. when the wedges are machined into the hosiery. In addition, the wedges interfere with the installation of Dichtrin-ges. The localization of the Hiilse in the axial direction and in the direction of rotation is complicated in the known construction. The Hiilse and its attachment are also associated with many loose parts.
    The object of this invention is to bring forth a roll for a fiber web machine, which is simpler in its construction and assembly. The characterizing features of the roller according to the invention are the protection claim 1 to entneh-men.
    In the roller is arranged a formschliissige lock between at least one arranged in connection with one end of the shell Achshiilse and the axle construction. According to one embodiment, the formschliissige lock between the axle shaft and the axis of the associated axle journal neck is arranged.
    With the invention of the need for a separate wedge in Achshiilse abge-creates and the corresponding end result is achieved by a matching deformation of the axle. This simplifies the final construction of the roll and especially facilitates its configuration. In addition, the Achshiilse is less affected by changes in shape. The sealing between the axle and the axle construction is also successfully implemented on the cylinder surface of the axle construction. This also facilitates the assembly.
    According to one embodiment, the formschliissigen lock at least one on the axle construction, such as arranged at the neck of the journal and cut, arranged in Achshiilse be assigned to at least one shoulder element, which are arranged, for example, provided in the Achszapfenhals the axle design section can. In this case, the axle shaft can be positioned in the axial direction with the aid of the shoulder element located in the axle shaft and the drag surface located in the axle construction. The shoulder element and the resistance surface also position the shaft in the direction of rotation.
    By means of the invention, when locking and positioning the axle shaft, separate parts such as, for example, wedges and sealing cover with fastening material can be omitted. Other additional advantages that are achieved by the invention are described in the description and the attached claims.
    The invention, which is not limited to the embodiments presented in the following, will be described below with reference to the drawing. In the drawings: Fig. 1 shows a principal example of a shoe roll of the press section of a fiber web machine.
    FIG. 2 shows an example of the end of a roll according to the invention, transverse to FIG
    3 shows the end of a roll shown in FIG. 2 viewed from the side of the machine without shingles; FIG. 4 shows an example of the shank shown in FIG. 2; and [FIG. Fig. 5 shows an example of the attachment of the axle shank shown in Fig. 4 on the axle journal of the roller as a section.
    Fig. 1 shows, as a rough diagram, a principal example of the roller 10 of a fiber web machine. Here, the roller 10 is formed as a shoe roll of the press section. The roller is in this case associated with a known per se and axle construction comprising the center located in Fig. 2 and 3 illustrated pressure axis 29 and the Achszapfenhals 28 and the subsequent journal 19 at both ends. The journal necks 28 are located between the thrust axis 29 and the stub axles 19th
    The roller 10 is provided to hold up, for example gestiitzt on its journals 19 on the support frames. The jacket 12 shown in FIG. 1 is arranged around the pressure axis 29 assigned to the axle construction. In the case according to the embodiment, the jacket is a belt jacket 12 of the shoe roll 10 which is known per se and rotates with its ends 26 about the stationarily supported axle construction, preferably about the pressure axis 29.
    In Fig. 2, an example of the end of the roll 10 of a fiber web machine is shown a little more precisely obliquely viewed from the side of the machine. In conjunction with at least one end 26 of the shell 12 is a Achshiilse 13 is arranged. In the same way, in connection with Achshiilse, one can also talk about a spigot axle. To Achshiilse in Fig. 2-5 not shown bearing of the end ring 26 is arranged. Thus, the end ring 26 is also about the Achshiilse 13 and is provided here for rotation. Between the bearing of Achshiilse 13 and the end ring 26 can still be arranged, for example, a leather bellows Or a corresponding seal to prevent the ingress of larger particles into the interior of the roller 10. In the Achshiilse 13 is an opening 24, from which it is arranged around the axle 11. In addition, the Achshiilse 13 is provided for locking on the axle 11 in the direction of rotation of the shell 12 and in addition, the Hiilse 13 can be locked in the axial direction. In general, it is also possible to talk about the positioning of the sleeve 13 with respect to the axle construction 11.
    Between the Achshiilse 13 and the axle 11, a seal 14 may be arranged. One of the tasks of the seal may be to hold the belt 12 lubricating medium within the roller 10 in conjunction with the axle 11.
    Between the Achshiilse 13 and the axle 11 a formschliissige Verrie-gelung 15 is provided. This simplifies, for example, the placement of the sleeve in the roller 10 and, in particular, its attachment to the axle construction 11. The positive locking 15 also reduces the number of loose parts. In addition, the formschliissige lock 15 improves the positioning accuracy of Achshiilse 13. This is because thanks to the formschliissigen lock 15 Achshiilse always adjusts itself in the right place.
    In Fig. 2, an example of the formschliissige lock 15 in the roller 10 is shown. In this case, the formschliissige lock between the Achshiilse 13 and the
    Axle construction 11 associated roller provided. According to one embodiment, the positive lock 15 may be assigned at least one section 18 arranged on the axle journal 28. The cut on the axle journal neck 28 may be segmented, forming a local plane surface 30 on the cylinder surface of the axle. The planar surface 30 can be manufactured by machining. This is particularly well visible in Fig. 3, in which the end of the roller 10 obliquely viewed from the side without the axle sleeve 13 is shown.
    Accordingly, in the axle sleeve 13, which is shown in Fig. 4 obliquely separated from the roller 10, at least one shoulder element 20 may be arranged, which can be arranged in section 18 on the Achszapfenhals. The shoulder element 20 is now located in the opening 24 of the axle sleeve 13 on the inside of its circumference. The Achshiilse 13 can be locked in place with screws 25, for example. For the screws can be provided at the plane 30 Plane equipped with threads bore. In the case according to the embodiment, there are two locking units 18, 20, and they are located on the mutual sides of the axle journal 28 and shaft 13. At least one of the locks 15 may be located on the stronger side of the eccentric sleeve 13. If the level 18 and the shoulder element 20 are arranged on the neutral axis, the tension will cause no problems.
    Fig. 5 shows an example of the attachment of the axle shank shown in Fig. 4 on the axle journal 28 of the roller 10 as a section. According to one embodiment, the axle sleeve 13 may be associated with an axially outer end face 16 and an axially following wearing part 17. The shoulder element, more generally the positive lock 16, can be arranged on the end face 16. In addition, it is provided that the end face 16 and the sleeve part 17 form a uniform piece, wherein a separate cover part is not needed.
    The seal 14, which is also visible in Fig. 5, may also be associated with a recess provided on the Achszapfenhals 22, a sealing groove for the seal 21. The seal 21 is provided to seal against the Achshiilse 13. The seal 21 runs around the entire axle journal 28.
    From the Achshiilse 13, the Hiilsenteil 17 may be provided for carrying the load. In this case, the load in the axial direction of the outer-side inner periphery of the Schulterele-element 20 of the Achshiilse 13 is supported. According to one embodiment, the seal 14 is disposed in the area provided for supporting the load of the waist part 17.
    The opposing surfaces of the Hiilse 13 and the axle 11 are machined precisely treated, mutually corresponding cylindrical surfaces that carry the main part of the loads of the end or storage. The unit may be provided so tightly that the sleeve 13 is warmed up prior to installation to facilitate installation.
    In the context of the invention, a fiber web machine is understood as meaning a paper, board and soft paper machine and a drying machine for pulp.
    It is to be understood that the foregoing description and the related figures are only illustrative of the invention. Thus, the invention is not limited to the above-mentioned Or defined in the claims, but to a specialist it is obvious that many modifications and changes are possible within the scope of the inventive idea defined in the claims.
