Description

Technical Field

[0001] The present application relates to the technical field of bearing manufacturing and processing, and in particular to a bearing housing that is easy to disassemble. Background Art

[0002] Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Bearings will rotate at high speed for a long time when working. Over time, the internal balls or rollers will be worn due to friction, resulting in increased friction. At this time, the internal balls or rollers need to be replaced. Currently, they are often replaced by forced disassembly, but forced disassembly may cause wear of the outer shell that does not need to be replaced. In severe cases, the internal parts will be permanently damaged and cannot be repaired or even scrapped. Summary of the invention
