Preloading regulating mechanism for rolling bearings

摘要

A preloading regulating mechanism for rolling bearings which is adapted to be used to adjust an axial force on the rolling bearings is disclosed. The preloading regulating mechanism includes a first fixing member, a regulator disposed in the first fixing member for allowing a user to apply a torque thereon, an annular plate having a first face connected to the regulator for being moved in response to the torque exerted from the regulator, a resilient member having a first end connected to a second face of the annular plate for urging against the annular plate to form an elastic force, and a movable annular element connected to a second end of the resilient member for transmitting the elastic force to form the axial force on the rolling bearing in response to the motion of the annular plate.
