Description

Technical Field

[0001] The utility model relates to the technical field of bearing inner ring clamping, in particular to a bearing inner ring clamping and fixing component. Background Art

[0002] The main function of the bearing is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. It can be understood that it is used to fix the shaft so that it can only rotate and control its axial and radial movement. It is mainly composed of an inner ring, an outer ring, a rolling element, and a retainer. However, in actual use, the existing clamping and fixing device is generally fixed by clamping the upper and lower planes of the inner ring of the bearing because the surface of the inner ring of the bearing is provided with a groove for the movement of the ball. The clamping structure always occupies a certain bearing surface during the processing, resulting in the clamping part being unable to be processed, and a secondary adjustment of the clamping is required, which is very inconvenient to use.
