A bearing for a ball screw drive may include a ball nut that is rotatable about a longitudinal axis and intended to receive a threaded spindle concentrically. The ball nut may be arranged in an inner ring and at least partially in an intermediate ring and an outer ring of the bearing. A belt pulley may be connected to the intermediate ring for rotation therewith, wherein an outer circumferential surface of the inner ring may be convex in some regions and an inner circumferential surface of the intermediate ring may be concave in some regions. The ball nut may be arranged in the bearing so as to be tiltable with respect to the belt pulley. The inner ring may be connected to the ball nut for rotation therewith and may be immovable in an axial direction. The intermediate ring may be connected via spring elements to the inner ring for rotation therewith.

Bearing for a ball screw drive

The invention relates to a ball screw () comprising a ball nut (), a roller bearing () and a belt pulley () arranged on the roller bearing (). The ball nut () is arranged in the roller bearing () such that there is no reduction in tension between that of the belt pulley () and an assisting engine arranged to the side of the ball screw ().

Ball screw having bearing compensation

A bearing arrangement may involve two spring systems that are decoupled from one another. Some bearing arrangements may include components such as a bearing housing, a bearing, spring elements for supporting the bearing in the housing, and an abutment that can be moved in an axial direction of the bearing. Further, a method for assembling a bearing arrangement may involve a compensation mechanism having dimensions that can be subsequently adapted.

Bearing arrangement with two axially acting spring systems

The invention relates to a servo-assisted steering system, in particular for a motor vehicle, having a servo motor which drives an axially displaceable component via a nut () which is mounted in a frame () in a rotatable manner in a bearing (), wherein the nut () engages with a threaded spindle () formed on the component and is supported via the bearing () elastically with respect to the frame () in the axial direction by means of spring elements () and is supported on the frame () in the radial direction along a narrow encircling contact surface (), wherein the spring elements () are corrugated springs.
