Embodiment Construction

[0042] figure 1 A rolling bearing 1 for clutch bearing units in automotive applications is disclosed. The rolling bearing 1 is suitable for any other application with rotational movement.

[0043] A rolling bearing 1 with a central axis X1 comprises: a rotatable outer ring 2; a stationary inner ring 3; a row of rolling bodies (here balls) 4; a cage 5 for retaining the The rolling elements 4; the axial retaining flange 6 for the rolling elements 4, which is fixed to the outer ring 2; and the protective flange 7, which is made of a thin sheet metal blank (thin sheet metal blank), for example (mild steel) DC01 or DC04.

[0044]The stationary inner ring 3 comprises a tubular portion 16 extending along a central axis X1 provided with an outer concave raceway 16a for the rolling bodies 4 . The stationary inner ring 3 also comprises an annular radial portion 17 extending radially outwards from said tubular portion 16 in a direction opposite to the central axis X1. Advantageously,...

Abstract

The invention relates to a rolling bearing (1) centered on a central axis (X1) and comprising: an outer ring (2), an inner ring (3), a rolling element (4) arranged between the two rings and the protection flange (7), a ring (2) comprises a tubular portion (8) centered on the central axis and provided with rolling ways (14, 14a) for a rolling body; and an annular radial portion (9) which extends radially from the tubular portion and defines a support surface (13) for axially supporting an annular radial base (19) provided to the protection flange. The tubular portion (8) comprises a frustoconical portion (23) extending axially between the radial portion (9) and the rolling way (14) and towards the central axis to define an annular groove (18). The protection flange also includes an annularsupport portion (21) extending axially from the annular radial base (19) and includes at least one radial projection (22) disposed within the groove (18) of the ring (2).

Description

technical field [0001] The invention relates to the field of rolling bearings, in particular to rolling bearings provided with protective flanges installed in the rings of said bearings. The invention is particularly applicable to clutch bearing units in which race rings are produced by cutting and punching sheet metal blanks. The present invention can also be applied to MacPherson suspension thrust bearings. Background technique [0002] It is known to use clutch bearing units in motor vehicle applications for actuating a rotating diaphragm of a gearbox by a translating piston. To this end, the clutch bearing unit comprises a bearing with rolling bodies, a rotatable ring to be in contact with the diaphragm, and a stationary ring provided with a bore to accommodate said translating piston. [0003] When the driver operates the clutch pedal, the piston is pushed axially towards the clutch bearing unit. The translational displacement is transmitted forward to the diaphragm,...
