Load-dependent pre-stressed bearing arrangement for supporting shaft, has ball bearings for supporting shaft, where ball bearing is axially prestressable by actuator

摘要

The load-dependent pre-stressed bearing arrangement (1) has ball bearings (2,3) for supporting a shaft (4). The ball bearing is axially prestressable by an actuator (15). The actuator has two ramp elements which are brought in operative connection with each other. The former ramp element is pivoted opposite to the latter ramp element and is axially displaced along a rotational axis (7). The actuator is a pre-assembled component formed of the ramp elements which are held together in a form -fit manner. An independent claim is also included for an actuator with a clamp body arranged between the ramp elements.
