Embodiment Construction
[0021] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.
[0022] see figure 1 , the present invention provides a bearing constant pressure preloading device, which includes a fixed first bearing 1, a second bearing 2 that can be adjusted in the axial direction, and a first end that abuts against the outer ring of the second bearing 2. Preload component 3. Among them, the first bearing 1 is fixedly arranged between the rotating shaft and the stator 4 to bear the load; the second bearing 2 is arranged between the rotating shaft and the stator 4 and is adjustable in the axial direction; the preload assembly 3 is a compressible and stretchable elastic assembly , for bearing preload, and the preload F 0 It is transmitted to the second bearing 2 and the first bearing 1 in the form of deformation. Both the fi...
