Example Embodiment
[0017] Example 1
[0018] A bearing axial pre-tightening mechanism includes a bearing cover, a pre-tightening cover, a pre-tightening screw and its lock nut; the end face of the bearing outer ring is axially positioned with the pre-tightening cover, and the pre-tightening screw pushes the bearing outer ring axially through the pre-tightening cover , Realize the axial preload of the bearing and lock it by the lock nut.
[0019] There is a threaded hole in the center of the bearing cover, and the pre-tightening screw is installed in the threaded hole in the center of the bearing cover. The edge of the pre-tightening cover has an annular boss, the inner diameter of the boss is larger than the outer diameter of the bearing inner ring, and the end surface of the bearing outer ring is pushed through the end surface of the boss.
[0020] The specific implementation process of this embodiment:
[0021] Install the bearing in the mounting hole of the rack, and cover the inner hole of the bear...
