A bearing retainer 10 for improving bearing deformation according to the present invention will be further described with reference to fig. 1 to 3.

Referring to fig. 1-3, a bearing press plate 10 for improving bearing deformation includes a main press plate 1, an inner hole 11 penetrating through the main press plate 1, a connecting hole 12 surrounding the inner hole 11 and disposed on the main press plate 1, a pressing surface 13 disposed on a side surface of the main press plate 1, a groove 14 formed by the pressing surface 13 sinking into the main press plate 1, the groove 14 disposed between the connecting hole 12 and the inner hole 11, and one side of the groove 14 communicated with the inner hole 11.

In this embodiment, the diameter of the inner hole 11 is larger than the outer diameter of the inner ring of the bearing 40 and smaller than the inner diameter of the outer ring of the bearing 40, so that the main pressure plate 1 can be ensured to press the outer ring of the bearing 40, and the inner ring of the bearing 40 is prevented from being pressed, and the rotation of the inner ring is prevented from being influenced. The connecting hole 12 is used for the threaded connecting piece 20 to pass through, and the threaded connecting piece 20 is favorable for fixing the bearing pressing plate 10 which improves the bearing deformation on the bearing seat 30.

Compared with the prior art, the main pressure plate 1 is provided with the groove 14, the groove 14 is formed by sinking the pressing surface 13, the groove 14 is arranged between the connecting hole 12 and the inner hole 11, and one side of the groove 14 is communicated with the inner hole 11. When the threaded connector 20 is screwed, the part of the main pressure plate 1 close to the connecting hole 12 is forced to deform downwards under the action of the screwing force of the threaded connector 20. Due to the provision of the groove 14, the groove 14 serves to unload the deformation so that it is not directly transmitted to the portion of the main platen 1 that is in contact with the bearing 40 (corresponding to the portion of the invention where the groove 14 is located) at the closest distance.

With the structure of the present embodiment, the transmission process of the preload force of the threaded connector 20 is as follows: under the tightening force of the threaded connector 20, the portion of the main pressure plate 1 near the connecting hole 12 is forced to deform downward. The deformation is transmitted to the side portions of the main platen 1 (both sides of the groove 14) which are in contact with the bearing 40 while bypassing the groove 14 and being divided into two directions from both sides of the groove 14. In this way, the force transmission path is extended while increasing the actual contact and force-receiving area between the main pressure plate 1 and the bearing 40. The pretightening force of the threaded connecting piece 20 is uniformly dispersed on the bearing 40, so that the local stress of the bearing 40 is avoided being overlarge, the reduction of the deformation of the bearing 40 is facilitated, and the service life of the bearing 40 is prolonged.

According to the embodiment of the present invention, the inner hole 11 is circular and the inner hole 11 is provided at the center of the main pressure plate 1.

It should be noted that the connecting holes 12 are used for the threaded connection 20 to pass through, and the number of the connecting holes 12 may be 1 or more than 1 according to the actual installation and design requirements. When the number of the connecting holes 12 is 1, one side of the main pressure plate 1 can be fixed by using the threaded connecting piece 20, and the other side of the main pressure plate 1 can be fixed by using other structures (such as clamping, clamping heads and the like). In this way, a stable fixation of the main platen 1 is achieved.

When n is more than 1, the n connecting holes 12 are uniformly distributed by taking the axis of the inner hole 11 as the center. The structure is beneficial to improving the uniformity of locking and stress.
