Clamp spring, shaft assembly and bearing seat assembly

Abstract

The embodiment of the invention provides a clamp spring, a shaft assembly and a bearing seat assembly. The clamp spring comprises a clamp spring body which is in a circular arc shape, the axial thickness of the clamp spring is continuously decreased or increased from the radial outside to the radial inside in the radial direction of the clamp spring, the circumferential length of the clamp springis changeable, and after the circumferential length of the clamp spring is determined, a first end of the clamp spring and a second end of the clamp spring are fixed in the circumferential direction of the clamp spring. Therefore, the circumferential length of the clamp spring can be adjusted to make the clamp spring closer to the bottom of a clamp spring groove, moreover, since the axial thickness of the clamp spring is continuously decreased from one of the radial outside and the radial inside to the other in the radial direction of the clamp spring, the clamp spring can compensate a gap between the clamp spring and a bearing, the bearing is pressed and fixed, and thus the fixing effect of the clamp spring is improved.

Description

Technical field [0001] The embodiment of the present invention relates to the field of bearings, in particular to a circlip, a shaft assembly and a bearing seat assembly. Background technique [0002] When the bearing is installed on the shaft or the bearing seat, in order to fix the bearing in the axial direction, the bearing generally needs to be axially positioned. The axial positioning of the bearing has two types: complete positioning and incomplete positioning, which can be selected according to actual needs. [0003] At present, the way to fully locate the bearing in the axial direction is to use threaded fastening to axially compress the inner or outer ring of the bearing to achieve the purpose of axial positioning. However, the complete positioning of the outer ring in this way needs to be based on the surrounding parts Specially customized special quality pressure plate, and need to arrange the bolt position reasonably to ensure that the bearing pressure plate is balance...

AI Technical Summary

Problems solved by technology

However, due to the tolerances in the size of the processed circlip, the width and position of the circlip groove, and the size of the processed bearing, when the circlip is installed in the circlip groove, there will be a certain gap between the bearing and the circlip, and the bearing will be affected by the axial force. There will be a possibility of movement and slipping in the end, and the fixing effect is not very good
