When the nut 128 at the end of the drive pinion shaft 110 opposite to the drive pinion 102 is tightened, a compressive force is applied to the plastic spacer 126 via the cylindrical portion of the flange companion 111 to cause plastic deformation. The two inner races 122 and 124 move in a direction close to each other. On the other hand, the outer races 130 and 132 of the bearings 106 and 108 are prevented from moving in the proximity direction by the differential carrier 134.

- the positioning of the drive pion 102 in the axial direction needs to be assembled by adjusting the thickness of the adjustment shim 136 while checking the contact condition. Since the tooth contact is affected by an error of several / z m, a slight machining error in each part of the device becomes a problem. For this reason, it is necessary to check the tooth contact by assembling parts such as the drive pion 102 and the ring gear 104 for each final reduction gear, and to perform shim adjustment work, which requires a lot of man-hours. is doing

- FIG. 3 is a cross-sectional view showing a schematic configuration of a conventional vehicle final reduction gear.
- FIG. 1 is a schematic cross-sectional view of a vehicle final reduction gear 10 that employs the hypoid gear of the present embodiment.
- This vehicle final reduction device 10 is provided in a FR vehicle, and distributes the engine driving force transmitted by a propeller shaft (not shown) to the left and right rear wheels. At this time, the rotation of the propeller shaft is decelerated and transmitted to the rear wheels, and when there is a difference between the rotational speeds of the left and right rear wheels, a differential operation is performed to absorb this.
- the reduction gear device that achieves the reduction function of the final reduction device 10 is a hypoid gear device including a gear pair of a drive pion 12 and a ring gear 14.
- the drive pion 12 has a cylindrical outer shape and is provided on the drive pion shaft 16.
- the drive pinion shaft 16 extends on both sides of the drive pinion 12 (in the vertical direction in the figure), and is rotatably supported on the differential carrier 22 by bearings 18 and 20 on both adjacent sides.
- the drive pion 12 is formed on the drive pion shaft 16 as an integral member. That is, a blank in which the drive pion 12 is formed integrally with the drive pion shaft 16 is manufactured, and then the gear is cut by cutting or the like, so that the drive pion 12 and the drive pion shaft 16 become a single body. It is formed.
- the bearings 18 and 20 are ball bearings, and are not provided with an adjustment shim for adjusting the position in the axial direction, and the machining contact surfaces of the differential carrier 22 and the drive pion 12 that contact the bearings 18 and 20 are precisely processed.
- the position in the axial direction is determined by the degree.
- the bearings 18 and 20 are not given any preload.
- the lower bearing 18 in the figure is a single-row angular ball bearing and the upper bearing 20 is a double-row angular ball bearing. Shims and other forms that do not require preloading can be used as appropriate, taking into account the conditions of use. For example, a deep groove ball bearing or a cylindrical roller bearing can be employed.
- a flange companion 24 is coupled to the drive pion shaft 16 at the upper end in the figure by a nut 26, and is connected to the drive shaft via the flange companion 24 and driven.
- the ring gear 14 having a tooth surface conjugate with the tooth surface of the drive pion 12 and meshing with the tooth surface is coupled to the differential case 28 so as to be integrated therewith.
- the differential case 28 is rotatably supported by the differential carrier 22 via two bearings 30 and 32.
- the differential case 28, the differential pinion shaft 34 fixed in a state of passing through the differential case, the differential pinion 36 accommodated in the differential case 36, and the differential side gear 38 constitute a differential device that achieves the differential function of the final reduction gear 10.
- the differential pinion shaft 34 is arranged in a direction perpendicular to the rotational axis of the ring gear 14, and two differential pinions 36 are rotatably supported on the shaft 34!
- Two differential side gears 38 are arranged so as to mesh with each of these two differential pinions 36 and rotate around an axis orthogonal to the differential pinion shaft 34.
- the differential side gear 38 is splined to the left and right flange companions 40. These flange companions 24 and left and right drive shafts (not shown) are coupled to transmit driving force to the left and right rear wheels.
- the tooth surfaces of the drive pion 12 and the ring gear 14 are calculated by the gear design method described in the aforementioned Japanese Patent Application Laid-Open No. 9-53702 and International Publication No. 01Z65148. .
- the drive pinion 12 is a cylindrical gear whose tooth surface is an involute helicoid surface, and the ring gear 14 has a conjugate tooth surface of the tooth surface of the drive pinion 12. Since the drive pion 12 is a cylindrical gear and has an involute helicoid tooth surface, even if the drive pion 12 is slightly displaced in the axial direction, the tooth contact is not affected. That is, a regular balance is maintained.
- the bevel gear has an outer shape that is a truncated cone, If this occurs, it is clear that the distance between the meshing gears changes, and that the regular meshing cannot be maintained.
- the involute helicoid tooth surface is a surface formed by moving the involute curve defined in one plane perpendicular to the rotation axis of the gear in the axial direction while twisting at a constant torsion angle. Even if the gears are displaced in the axial direction, the normal balance is maintained. Of course, if the misalignment width of the two gears that are in meshing changes, the misalignment rate will change and the load resistance will change.
- the novoid gear of this embodiment like the conventional hypoid gear, it is necessary to adjust the tooth contact by the adjustment shim and position the drive pion in the axial direction with high accuracy by applying preload to the bearing. There is no. This greatly reduces the man-hours for manufacturing the final reduction gear.
- the support structure of the drive pion 12 is cantilevered by the two bearings arranged on the drive shaft side (upper in the figure) from the drive pion 12. It can also be a structure.
- FIG. 2 is a cross-sectional view showing an outline of a final vehicle deceleration device 50 according to another embodiment.
- This final reduction gear 50 differs only in the configuration of the bearing that supports the drive pinion 12 of the final reduction gear 10 described above. That is, the bearings 18 and 20 of the final reduction device 10 are ball bearings, whereas the bearings 52 and 54 of the final reduction device 50 employ tapered roller bearings. Further, an adjustment shim 56 is provided between the outer race of the bearing 54 on the propeller shaft side (the upper side in the figure) and the differential carrier 22 to apply a preload to eliminate axial play.
- the other configuration is the same as that of the final reduction gear 10 described above, and the description thereof is omitted.
- the final reduction gear device 50 uses a pair of tapered roller bearings, an adjustment step by the adjustment shim 56 is required to apply a predetermined preload during assembly.
- the tooth contact is not affected by the axial position of the pion, it is the bearing preload that is adjusted by the adjustment shim 56. Therefore, the shim adjustment process is different from the adjustment work related to the drive pinion shaft of the conventional final reduction gear, in which it is not necessary to check the tooth contact, and the man-hour is also small.
- the drive pion is a cylindrical gear, it can be supported at both ends, and the bearing can be downsized and the outer shape of the apparatus can be downsized.
- the present invention can also be applied to other devices that employ the force hypoid gear described for the final reduction gear for vehicles, particularly for FR vehicles.
