Roller bearing e.g. taper roller bearing, for storing shafts in switching- or steering gears of motor cars, has board comprising border ring actuatable by actuator, and stationary supporting board integrally formed with inner bearing ring

摘要

The bearing (1) has inner and outer bearing rings (3, 4) between which rolling members (5) e.g. needles, cylindrical rollers and taper rollers, are arranged, where one of raceways (7a, 7b) is defined by a board (11) that axially guides the rolling members. The board has an axially movable border ring (15) actuatable by an actuator (21). The board has an additional stationary supporting board (17) integrally formed with the inner ring. The actuator formed as a mechanical spring (23), a gas-filled support or a hydraulic fitting with a spring system is supported at a supporting element (25).
