    专利说明:

    The invention relates to a device for releasing play of meshing toothings of a toothed wheel drive comprising a toothed wheel arrangement, wherein the toothed wheel arrangement comprises a main toothed wheel, which has a first toothing, and a toothed wheel, which has a second toothing, which can be rotated relative thereto in the circumferential direction. wherein the main gear has a hub portion on which the rotatable gear is arranged. Furthermore, the invention relates to a spur gear drive comprising at least a first gear and a meshing with this gear device for play release meshing Ver-toothings, wherein the first gear is undivided.
    Gear arrangements of the type mentioned, as are known, for example, from WO 2005/090830 A1 or WO 2005/090829 A1, serve to reduce the backlash between two meshing gears. In Stirnradan-drives with high torsional vibration excitation and high deflection of the waves, the backlash must be relatively large, so that the gear assembly can meet these conditions.
    It is the object of the invention to provide a backlash for spur gears with high torsional vibration excitation and high deflection of the waves available.
    This object of the invention is achieved in the device mentioned above in that radially below the main gear a tolerance compensation selement is arranged, which comprises a shaft part and a compensation part, wherein the compensation part is connected to the shaft part and the hub part of the main gear, so that the main gear is exclusively connected via the compensating part with the shaft part, and wherein the compensating part consists at least teilwei-se of a rubber-elastic material. Further, the object of the invention in the above-mentioned spur gear is achieved in which the device is designed for play release as just described.
    The advantage here is that due to the elastic properties of the equalization part torsional vibrations and deflections of the shaft can be better ausgegli-chen or damped. It is thus possible to equip spur wheel drives with such gear arrangements, which have a very high axis tolerance in the range of ± 0.5 mm. In conventional spur gears, the axle tolerance is typically in the range of ± 0.15 mm. In addition, with this device for clearance clearance due to the compensating part and a Redukti-on the Verdrehflangenenspiels can be achieved, whereby the meshing engagement of a further toothing in the toothing of the gear arrangement can be improved. As an additional side effect, a reduction in noise emission of the intermeshing gears during operation could also be observed. It is also possible to provide a Cluberlastschutz for the spur gear drive with this device for game clearance.
    According to a variant embodiment of the device for play release can be provided that the compensating part is material and / or positively connected to the shaft part and / or the hub part. It is thus a firmer connec tion between the compensating part and the shaft part or between the compensating part and the hub part achieved, whereby the risk of tearing off the compensating part can be better avoided even at higher dynamic loads of the compensating part due to the torsional vibration excitations and the deflection of the shaft ,
    For a better understanding of the invention, this will be explained in more detail with reference to the following figure.
    It shows in a simplified, schematic representation:
    Fig. 1 a spur gear;
    Fig. 2 shows a detail of a device for game release in cross-section.
    By way of introduction, it should be noted that the location settings chosen in the description, such as top, bottom, side, etc. related to the immediately described and illustrated figure and these position information in a change in position mutatis mutandis to transfer to the new location.
    In Fig. 1, a spur gear 1 is shown schematically. This includes known-Lich at least a first gear 2 and at least one second gear, which is in meshing engagement with the first gear 2. The first gear 2 has for this purpose on a radially outer periphery of a spur gear teeth 3.
    The first gear 2 is an undivided gear 2, i. in that it is formed integrally from a metallic sintered material or from a solid metal, for example produced by means of a casting process.
    The second, meshing with the first gear 2 gear is formed by a device 4 for play clearance of the meshing spur gear teeth 3 of the first gear 2 with the toothing of the device 4, which is shown in more detail in Fig. 2.
    The device 4 for play release has a gear arrangement 5. The gear arrangement 5 comprises a, in particular metallic, main gearwheel 6 and a gearwheel 7 which can be rotated relative to it in the circumferential direction, in particular metallic. The latter can also be referred to as a sprocket.
    The main gear 6 has the front side a first toothing 8. The verdrehba-re gear 7 has the front side a second toothing 9. The second toothing 9 is not arranged in the axial direction in alignment with the first toothing 8 of the main toothed wheel 6.
    The main gear 6 also has a hub portion 10, on which the rotatable gear 7 is arranged. The hub portion 10 is preferably integrally formed with the remainder of the main gear 6, i. that the skin gear 6 is preferably formed eintei-lig.
    The rotatable gear 7 is biased with at least one Fe element, not shown, for example, a Ω spring, against the main gear 6 in the circumferential direction. For this purpose, on corresponding surfaces of the main gearwheel 6 and the rotatable gearwheel 7, corresponding cams may be present, on which the spring element is supported.
    Such a gear arrangement 5 is shown, for example, in FIG. 1 of AT 507 071 B1.
    It should be mentioned at this point that in addition to the use of a Ω spring there are other possibilities to bias the rotatable gear 7 against the main gear 6, such as by means of elastomeric spring elements, etc. The gear assembly 5 is therefore not limited to the Use or the arrangement of the Ω-spring for this purpose.
    Unlike conventional gear arrangements, the gear arrangement 5 is not arranged directly on a shaft 11. Between the gear assembly 5 and the shaft 11, a tolerance compensation element 12 is arranged concentrically to the main gear 6.
    The tolerance compensation element 12 comprises or consists of a (em) shaft part 13 and a (em) compensation part 14.
    The shaft part 13 has a recess 15 for rotationally receiving the shaft 11. The shaft part 13 is preferably made of a metallic material, in particular of a sintered material.
    It should be mentioned at this point that the main gear 6 and / or the rotatable gear 7 is preferably made of a sintered material or are.
    The compensation part 14 consists at least partially, preferably entirely, of at least one rubber-elastic material, in particular an elastomer. The
    For example, elastomer may be selected from the group consisting of (X) NBR ((carboxylated) acrylonitrile-butadiene rubber), HNBR (hydrogenated nitrile rubber), a silicone rubber (VMQ), NR (natural rubber ), EPDM (ethylene-propylene-diene rubber), CR (chloroprene rubber), SBR (styrene-butadiene rubber), and mixtures thereof.
    By "at least partially" is meant that in the compensator 14, e.g. Stiffening elements, e.g. Fibers and / or threads, for example of metal, plastic, natural fibers, etc., or rods, etc. may be incorporated.
    The compensation part 14 is connected on the one hand to the shaft part 13 and on the other hand to the main gear 6. As a result, the gear arrangement 5 is exclusively connected via the main gear 6 with the tolerance compensation element 12 via the compensating part 14. The connection of the balancing part 14 with the shaft part 13 and / or the hub part 10 of the main gear 6 is preferably made material and / or positive fit.
    The positive connection can for example be made via at least one groove 16 in a radial outer end face of the shaft part 13 or a radially inner end face of the main gear 6, as indicated by dashed lines in Fig. 2. The elastomer of the compensating part 14 extends in this case into the groove 16 and fills these out preferably entirely.
    But it is also the reverse training possible that in the compensation part 14, a groove is formed, in which the shaft member 13 and the hub member 10 protrudes into it.
    Furthermore, such a (ring) groove can also be formed in at least one of the axial plane surfaces of the shaft part 13 and / or of the hub part 10 in the contact region of the compensating part 14 at these parts.
    The number of grooves 16 and / or their cross-sectional shape can be adapted to the respective requirements. For example, the groove 16 or the grooves 16 may have a dovetail-shaped cross-section.
    Alternatively, or in addition, the positive connection of the equalization part 14 with the shaft part 13 and / or the hub part 10 can also take place such that the compensation part 14 has a greater width in the axial direction gear arrangement 5 than the shaft part 13 or the hub part 10, so that it projecting on both sides over the shaft part 13 and the hub part 10. The end regions of the equalization part 14 may further have a larger diameter than a center region of the compensation part 14, so that the abutment surfaces of the compensation part 14 for the shaft part 13 and the hub part 10 are at least approximately U-shaped, as this is shown in Fig. 2. The compensation member 14 may have an overall H-shaped cross section. The compensating part 14 can thus be arranged covering the shaft part 13 and / or the hub part 10 in the respective contact region in an area-covering manner.
    It should be mentioned at this point that the compensation part 14 in the axial direction preferably at least over the entire width of the hub portion 10 and the main gear 6 and the shaft portion 13, viewed in the same direction, extends, in particular extends continuously, as also from Fig. 2 ersicht-Lich. Preferably, the compensation part 14 has at least the width corresponding to the width of those parts which has the greatest width in the same direction. In particular, however, the compensation part 14 has a greater width than this width.
    The cohesive connection between the compensating part 14 and the shaft part 13 and / or the hub part 10 can be produced, for example, by means of an adhesive or by directly vulcanising the compensating part 14 onto the shaft part 13 and / or the hub part 10.
    To compensate for this Achalance tolerances in the range of -0.5mm to 0.5 mm with this version of the device 4 for play clearance.
    Further, it is possible with the device 4 for clearance release to set a smaller Ver-rotational backlash.
    According to a variant embodiment of the device 4 for clearance release can be provided that axially outer edges of the shaft portion 13 and / or the hub part 10, i. the edges are provided in the transition region from a radial surface to axial end faces, with a rounding 21 to 24, in order to achieve a better connection of the hub part 10 and the shaft part 13 with the compensation part 14. In particular, this can better be prevented that the compensation part 13 breaks off under load in these transition areas.
    The radius of the rounding (s) 17 is preferably selected from a range of 0.1 mm to 2 mm, in particular from a range of 0.4 mm to 1.5 mm.
    The embodiments show or describe possible Ausführungsvarian-th the device 4 for game release, which should be noted at this point that also various combinations of the individual variants are alternatives to each other.
    For the sake of order, it should finally be pointed out that, for a better understanding of the structure of the device 4 for releasing the play, these or their components have been shown partially unevenly and / or enlarged and / or reduced in size.
