[0002] Bearings are a crucial component in mechanical engineering, primarily used to support rotating shafts or other moving parts, reduce friction and wear, and improve mechanical efficiency and reliability. Bearing fixing assemblies are devices used to reliably fix bearings to shafts or bearing housings to ensure that the bearings do not move axially or radially during operation, thereby guaranteeing the normal operation of the mechanical system.
[0003] Existing bearing fixing components typically use shaft shoulders, elastic retaining rings, or round nuts and retaining washers for limiting and fixing when fixing the shaft. However, using shaft shoulders can easily lead to high local stress and large wear, while using elastic retaining rings has a small load capacity and cannot meet the needs of high load applications. Using round nuts and retaining washers is cumbersome to install and remove and requires a high level of technical skill from the installers. Therefore, we propose a bearing with a fixing component.
