シールを取付けることも行われている。 Conventional devices of this type are, for example,
As disclosed in Japanese Patent No. 137726, a flange constituting a fork receiver is fitted to a cylindrical hub 1, an inner ring rotation type clutch release bearing is installed in the hub, and a cover fitted to the outer ring of the bearing is fitted around the axial center. an inward flange that extends toward the fork receiver and has an outwardly inclined surface; and an alignment seat that extends in the radial direction and has on both sides a plane in contact with the flange constituting the fork receiver and an inclined surface in contact with the inclined surface of the inward flange. A wave spring that is movably inserted into the hub and fixed on one side by a retaining ring fitted in a retaining ring groove provided on the outer diameter surface of the hub aligns the inclined surface of the inward flange with the inclined surface of the alignment seat. The centering position was maintained by pressing against the surface. In addition, in order to prevent dust and other foreign matter from entering the sliding contact surface between the alignment seat and the bearing, a dust-proof flange is provided that protrudes from the flange that constitutes the fork receiver toward the flange on the outer ring side. A labyrinth gap is provided between the hubs, or a hermetic seal is attached to the hub.

調整がむずかしいなどの問題がある。 In such a device, the cover and the outer ring are separate bodies, which increases the weight and requires more man-hours for assembly, resulting in higher costs. In addition, if the cover and the outer ring are not sufficiently fitted, only the outer ring may rotate, posing a danger in operation. In addition, manufacturing the dustproof flange requires cutting the flange of the fork receiver of the hub, which increases manufacturing costs and does not necessarily provide a fully satisfactory sealing effect. Furthermore, since a groove is provided on the outer peripheral surface of the hub for mounting the spring retaining ring, there is a problem in terms of the strength of the sleeve. Furthermore, since the bearing cannot be assembled into the cover until after the retaining ring and cover have been assembled into the hub, there are problems such as the clearance between the bearings changing during press-fit assembly, making it difficult to adjust the clearance.
この考案は、これらの問題点を解決すべくなさ
れたものである。 This invention was made to solve these problems.

するように防塵機能などの点で便利である。 Embodiments of this invention will be described below with reference to the drawings. In Fig. 1, a hub 2 into which a bearing 1 is fitted
At the front end of the portion, a large diameter portion such as a flange is formed by enlarging the inner diameter, and this portion constitutes the spring receiver 10. Wave spring 1 in contact with spring receiver 10
1 is inserted, and the cylindrical member 12, which is fitted into the hub 2 with a slight clearance, is pressed against the inward flange 5 of the outer ring 4. In this embodiment, the inward flange 5 is further provided with an inner cylindrical portion 5a extending axially outward from the inner diameter end, and the cylindrical member 12 is in contact with an end surface 5b of this inner cylindrical portion. Note that the cylindrical member 12 may be brought into direct contact with the inward flange and pressed toward the alignment seat 3 without providing the inner cylindrical portion 5a on the inward flange 5, but if the inner cylindrical portion 5a is provided, it will be described later. It is convenient in terms of dustproof function and so on.

Provides a shielding effect.

The coil spring 11a is replaced by the spring receiver 1 of the hub 2.
0 and the cylindrical member 12 to press the cylindrical member 12 toward the end surface 5b of the inner cylindrical portion 5a of the inward flange of the outer ring 4, but the effect is the same. FIG. 3 shows another embodiment of the cylindrical member 12, in which a rib 13a is processed to increase the strength of the tip of the outward flange 13. FIG. 4 also shows another embodiment of the cylindrical member 12, in which a rubber seal lip 15 is attached to the end of the outward flange, and the inward flange 1 of the inner ring 8 is attached.
4 to strengthen the sealing function and improve the dustproof effect.

く必要がないので、組立が容易となつた。 As described in detail above, this invention uses a spring such as a wave spring 11 or a coil spring 11a inserted in the front part of the hub to direct the inward flange 5 integral with the outer ring 4 toward the alignment seat 3 via the cylindrical member 12. Since I pressed it and maintained the alignment position,
There is no longer a need for a retaining ring groove on the outer diameter surface of the hub, and there are no longer any problems with the strength of the hub. Moreover, since the bearing and the inward flange 5 are integrated, there is no problem of the outer ring idling due to poor fitting between the cover and the outer ring. Since there is no need to put it between 5 and 5, assembly is easier.

ので内外輪を焼ばめする必要もなくなる。 Further, an outward flange 13 is formed on the cylindrical member 12, and its height is set to the inner cylindrical portion 5 of the inward flange 5 of the outer ring.
If the height is set so that it can face and cover the gap between a and the inward flange 14 of the inner ring 8, it will act as a shield for this part and have a dustproof effect, so the rear seal 9 can be omitted, making it even more compact. Become. Further, as in the embodiment shown in FIG. 4, if a seal lip is provided on the outward flange of the cylindrical member and is brought into sliding contact with the inner ring, the dustproof effect is further improved. Further, when the outer diameter of the outward flange 13 of the cylindrical member is made larger than the inner diameter of the inward flange 14 of the inner ring 8, the outward flange 1
3 functions as a stopper to prevent separation of the inner and outer rings, so there is no need to shrink-fit the inner and outer rings.
