Embodiment Construction

[0010] Referring to FIG. 1 , reference numeral 100 denotes a connecting device as a whole, which is used to connect a rolling bearing 10 with a hub 20 .

[0011] The bearing 10 has an axis of rotation A, and comprises an inner race 11 coaxial with the axis A, an outer race 12 coaxial with the inner race 11, and two interposed between the two races 11 and 12. The crowns 14 of the rolling body 15 are each mounted in a respective rolling track 16 .

[0012] In the embodiment shown in FIG. 1 , the rolling body 15 is defined as a sphere, and the inner race 11 comprises two annular portions 11 ′ mounted against each other with respect to the axis A on the hub 20 and each having A corresponding track 16.

[0013] The hub 20 comprises a flange 21 transverse to the axis A and a main shaft 22 integral with the flange 21 , extending along the axis A inside the inner race 11 and terminating in a small edge 23 which It is adapted to be rolled abutting the inner race 11 itself to close th...

Abstract

A connecting device (100) for a rolling bearing (10) to be connected to a hub (20), said connecting device being adapted to connect the inner race (11) of the bearing (10) to the cylindrical body of the hub (20) (22) connection with a peripheral connection profile (50) disposed around the cylindrical body (22) of said hub (20) and a complementary connection profile (50) disposed within said inner race (11) 60), and said complementary connection profile (60) has a complementary shape to said peripheral connection profile (50), so that said inner race (11) and cylindrical body (22) are angularly integrated with each other; Both profiles (50, 60) have a radius (R) that varies continuously with angle in a plane transverse to the axis of rotation (A) of the bearing (10), and both include at least one (A) corresponding raised portion (51, 61).

Description

technical field [0001] [1] The present invention relates to a connecting device for connecting a rolling bearing to a hub assembly. Background technique [0002] 【2】In general, rolling bearings include an inner race and are mounted by interference fitting the inner race on the main shaft of the hub and blocking the inner race by cold plastic deformation of the small annular edge of the main shaft adjoining the inner race on the hub. [0003] 【3】Practical experience can prove that even if the force exerted on the inner race by the deformed small annular edge is greater than the force sufficient to block the inner race in the axial direction, this does not prevent possible contact between the inner race and the main shaft. A necessary condition for random relative rotation, which generates noise and vibration and reduces the useful operating life of the bearing. Contents of the invention [0004] [4] The object of the present invention is to provide a connecting device for...
