Bearing and installation method thereof

Abstract

The invention discloses a bearing and an installation method thereof. The bearing comprises a bearing body (1) and a bearing seat body (2); the bearing body (1) is arranged in an installation cavity (3) of the bearing seat body (2); when the bearing is installed, a clamp ring (4) is firstly sleeved at the end part of the bearing body (1), meanwhile a clamp foot (5) of the clamp ring (4) is just placed in an opening (6) of the installation cavity (3), and then the clamp ring (4) is rotated to screw the clamp foot (5) of the clamp ring (4) in a slot (7) through a clamping part (8) on the slot to be locked. Furthermore, a groove (10) on the bearing body (1) is matched with a convex key (9) on the bearing seat body (2) to fix the bearing body (1), so as to stop the bearing body rotating with a shaft in the same direction. The invention has the advantages that the bearing has a simple structure, and is convenient for installation; parts cannot be damaged in a disassembling process; in addition, the bearing has a stable and firm structure and small installation gap; the possibility of vibration when the bearing operates is small, thereby the noise caused by vibration during operation ofthe bearing is improved.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a bearing and an installation method thereof. Background technique [0002] Bearings are common parts widely used in the machinery industry. Bearings have various structures and installation methods. The most common installation method is to press and deform the bearing bracket to fix the bearing. The disadvantage of this method is: once the bearing bracket is deformed during use, the bearing fixed by the bearing bracket cannot be easily disassembled. For this, the US Patent No. US6139189 discloses a new type of bearing installation method, which does not need to press and deform the bearing bracket to fix the bearing. However, the disadvantage of this method is that there is a certain installation gap between the outer surface of the bearing and the inner surface of the bearing bracket, and this gap will cause vibration and cause bearing noise.

AI Technical Summary

Problems solved by technology

The disadvantage of this method is: once the bearing bracket is deformed during use, the bearing fixed by the bearing bracket cannot be easily disassembled, even if it is disassembled, the bearing will be scrapped, and the stamping deformation itself will also cause damage to the parts

However, the disadvantage of this method is that there is a certain installation gap between the outer surface of the bearing and the inner surface of the bearing bracket, and this gap will cause vibration and cause bearing noise
