Abstract
A bearing arrangement for supporting an endless screw of a steering gear on a gear housing of the steering gear. The bearing arrangement including a radial bearing rotationally connected to the endless screw. A resilient retention element connecting the radial bearing to the gear housing. The retention element is connected at the radial bearing side to an outer face of an outer bearing ring and fixed to the outer face of the outer bearing ring in an axially non-movable manner with respect to a longitudinal center axis of the radial bearing.

A bearing arrangement for supporting an endless screw of a steering gear on a gear housing of the steering gear comprising:
- a radial bearing connected to the endless screw;
- a resilient retention element connecting the radial bearing to the gear housing, the retention element connected to an outer face of an outer bearing ring, the retention member fixed to the outer face of the outer bearing ring in an axially non-movable manner with respect to a longitudinal center axis of the radial bearing.
A steering gear for an electrical power-assisted steering system of a vehicle having a gear housing and an endless screw arranged in the gear housing comprising:
- a bearing arrangement rotatably supporting the endless screw in the gear housing;
- a recess in the housing, the recess including contact surface and a shoulder, the contact surface tapering radially inward;
- a retention element disposed in the recess, wherein an outer face of the retention element, having a complementary radially inward taper, engages the contact surface and a surface of the retention element contact shoulder.
A steering gear bearing system comprising;
- a radial bearing having an outer bearing ring, a recess in an outer surface of said outer bearing ring, said recess forming a shoulder;
- a resilient retention element engaging said shoulder and fixed against relative axial movement, between said outer bearing ring and said retention element along the longitudinal center axis of the radial bearing.
