Problems solved by technology

[0005] However, experience in the field of rolling bearings in general and in the field of rolling bearings for wheel hub assemblies in particular has shown that, when produced to such dimensions, the connection profiles for the above-mentioned connections have some disadvantages due to the typical stresses of Inherent in this application, and among other reasons it cannot guarantee that the transmitted torque is a constant value
In addition, the above-mentioned connecting device cannot meet the current demand of reducing cost and production time and ensuring the standardization of larger products.

Embodiment Construction

[0016] Referring to FIG. 1, reference numeral 100 denotes a connecting device for connecting a rolling bearing 1 to an outer body 7 as a whole.

[0017] The bearing 1 has a rotation axis A, and includes an inner race 2 coaxial with the axis A, an outer race 3 coaxial with the inner race 2, and a plurality of inner races 2 and outer races 3 Between the rolling body 4.

[0018] The inner race 2 is bounded in the axial direction by two annular surfaces 21 and 22 perpendicular to the axis A and in the radial direction by an inner cylinder 23 coaxial with the axis A. The outer race 3 is bounded in the axial direction by two annular surfaces 31 and 32 perpendicular to the axis A and in the radial direction by an outer cylindrical surface 33 coaxial with the axis A.

[0019] The outer body 7 defines a brake disc comprising an inner sleeve 71 engaged with the bearing 1 and an annular body 75 arranged perpendicular to the axis A and through which the inner sleeve 71 passes centrally. ...

Abstract

Connection device ( 100 ) for connecting a contact rolling bearing ( 1 ) to an external body ( 7 ), the connection device ( 100 ) presenting a peripheral connecting outline ( 5 ), which is obtained around a race ( 3 ) of the contact rolling bearing, and a complementary connecting outline ( 6 ), which is obtained inside the external body ( 7 ), and which presents a shape such as to complement the connecting peripheral outline ( 5 ) in order to render angularly integral in relation to each other the external body ( 7 ) and the first race ( 3 ), the connecting peripheral outline ( 5 ) and the complementary connecting outline ( 6 ) both presenting a radius (R) which is of variable angular dimensions with continuity on a plane which is transverse to the rotation axis (A), and are both provided, in relation to the rotation axis A, with at least one respective convex portion ( 51 ).

Description

technical field [0001] The invention relates to a connecting device for connecting a rolling bearing to an external machine body. Background technique [0002] US patent 6,230,841 relates to a rolling bearing for a hub assembly with a brake disc, wherein the bearing is provided with an outer race and the connection means comprises a peripheral connection profile and a complementary connection profile, the peripheral connection profile around the outer seat Coiled as a polygonal surface, the complementary connection profile is provided inside the brake disc and engages on the peripheral connection profile such that the brake disc itself and the outer race of the bearing are angularly integrated with each other. [0003] Due to the configuration of the peripheral connection contour, the above described connection device has mainly two disadvantages. On the one hand, the polygonal shape of the relevant surfaces, while ensuring the stability of the angular coupling between the ...
