Rolling bearing cage, rolling bearing and electric steering system of a motor vehicle

摘要

Rolling bearing cage (5) for an electric steering system of a motor vehicle, designed to ensure the circumferential spacing of the balls (4), comprising a plurality of first sockets (8) provided with means (8a) for axially retaining the cage (5) on a ball (4) and a plurality of second sockets (9) without means for axially retaining the cage (5) on a ball (4). Each of the first sockets (8), with a ball (4) housed in the first corresponding socket (8), has a first axial clearance, a first radial clearance and a first circumferential clearance (J1c) and each of the second sockets (9), with a ball (4) housed in the second corresponding socket (9), has a second axial clearance, a second radial clearance and a second circumferential clearance (J2c).

1. A rolling bearing cage (5) for an electric steering system of a motor vehicle, designed to ensure the circumferential spacing of a plurality of balls (4), comprising:
a plurality of first sockets (8) provided with means (8a) for axially retaining the cage (5) on a ball (4), and a plurality of second sockets (9) without means for axially retaining the cage (5) on a ball (4), each of the first sockets (8), with a ball (4) housed in the first corresponding socket (8), has a first axial clearance (J1a), a first radial clearance (J1r) and a first circumferential clearance (J1c) and in that each of the second sockets (9), with a ball (4) housed in the second corresponding socket (9), has a second axial clearance (J2a), a second radial clearance (J2r) and a second circumferential clearance (J2c), wherein the second radial clearance (J2r) is greater than the first radial clearance (J1r) and the second circumferential clearance (J2c) is greater than the first circumferential clearance (J1c).
