Description of the Related Art A bearing is formed separately from a member such as a shaft to which the bearing is usually mounted, and is fixed to the shaft or the like by fastening with a nut or the like. However, in this case, it is needless to say that a nut is required, and it is also necessary to provide a screw portion for screw-connecting the nut to a member to which the bearing is fixed, such as a shaft. There are problems such as.

題があった。In the bearing described in the above publication, it is necessary to form a projection, and there is a problem that the number of manufacturing steps is increased. Further, the parts on which the projections are formed form the rolling surfaces of the rolling elements of the bearing, and such members are hard and have poor workability, so that the number of manufacturing steps tends to increase. Further, in the caulking process, the projection itself may be deformed, and the member to which the bearing is fixed may not be engaged in the concave portion, so that a sufficient coupling state may not be obtained. Then, when a large caulking load is applied in order to sufficiently connect, there is a problem that the rolling surface is deformed.

部を有している。In order to solve the above-mentioned problems, a bearing according to the present invention comprises a shaft member and an inner ring member which is integrated with the shaft member by caulking to form at least a part of an inner ring. And an outer ring member arranged outside the inner ring and holding the rolling element together with the inner ring. Further, the shaft member has a caulking portion that deforms during the caulking and fixes the inner ring member. Furthermore, the inner race member is provided with a main body forming a rolling surface of a rolling element, and a crimped portion provided so as to extend in the axial direction from the main body, having lower rigidity than the main body, and substantially facing the caulked portion,
have. Further, the caulked portion has a protruding portion formed in an annular shape protruding radially outward in the vicinity of a tip end thereof.

In addition, the annular projecting portion acts on the swaged portion as a hoop of a vat, and efficiently generates residual stress in the swaged portion.

As shown, the bearing of this embodiment is configured as a double row ball bearing. Before assembly, the swaged portion 34 at the right end in the drawing of the wheel hub 10 extends rightward in the drawing as indicated by a broken line in the drawing, and its outer diameter is a clearance fit or an intermediate fit with the inner diameter of the inner ring member 20. Is a value such that When assembling, first, the row of balls 16 is arranged in contact with the rolling surface 18 of the wheel hub 10, and this is

4 and an enlarged cross section of the swaged portion 36 of the inner race member 20 are shown. Similar to FIG. 1, the shape of the caulked portion 34 before deformation is indicated by a broken line. The inner ring member 20 has an inner ring member main body 38 forming the rolling surface 24, and the above-described caulked portion 36
Extends from the main body in the axial direction of the wheel hub 10. The caulked portion 36 has a protruding portion 40 that protrudes radially outward from the distal end thereof and is formed in an annular shape. By providing the overhang portion 40, a groove 42 is formed between the overhang portion 40 and the inner race member main body 38.

２が正常に転動しなくなることを防止している。The caulked portion 36 is formed by caulking.
A force (indicated by an arrow in the drawing) is received in a direction normal to a contact surface with the caulking portion 34. Since the crimped portion 36 has the groove 42, the rigidity is set lower than that of the inner ring member main body 38, and most of the deformation due to the pressing force due to the caulking process occurs in the crimped portion 36. As a result, the rolling surface 24 is deformed by the deformation of the inner race member main body 38, and the ball 2
2 is prevented from rolling normally.

防止し、確実に締結力を発生させる機能を有している。The reaction force corresponding to the deformation of the swaged portion 36 due to swaging is generated by the wheel hub 10 and the inner race member 2.
The coupling force or the fastening force is zero. The overhang portion 40 has a function of reliably generating the reaction force. The overhanging portion 40 has an annular shape as described above, and suppresses the caulking portion 36 from expanding outward, that is, functions as a hoop of a tub, and increases the reaction force. Also, by supporting a part of the load of caulking in the overhanging portion 40, the stress generated in a portion of the caulked portion 36, in particular, at the bottom of the groove 42 is reduced. Preventing. As described above, the wheel hub 10
The fastening force between the inner ring member 20 and the inner ring member 20 is generated by a reaction force due to the elasticity of the inner ring member 20, and if plastic deformation occurs in the swaged portion 36, the fastening force is reduced. The overhang portion 40 has a function of preventing this and reliably generating a fastening force.

Is located radially inward (left side of the dashed-dotted line in the figure) from the base of the overhang portion 40, that is, the bottom of the groove 42. If the contact surface protrudes outward in the radial direction from the above-described region, the overhang portion 40 is deformed downward in FIG. 2 in addition to the above-described deformation that expands outward. This causes a stress concentration at the bottom of the groove 42, which increases the possibility of plastic deformation occurring. Since this plastic deformation is not preferable as described above, in order to avoid this, it is preferable that the contact surface is located radially inward of the bottom of the groove 42.

That is, the present invention can be applied to a case where an outer ring member or an inner ring member is fixed to a base member on which a bearing is provided, which is a shaft member or a housing, by caulking. To the outer ring member or inner ring member that is crimped,
A relatively weak portion is provided so that the rolling surface of the rolling element is not affected, and the reaction force of this portion secures the fastening force with the base member.
