Description

Technical Field

[0001] The utility model relates to the technical field of bearings, and specifically relates to a bearing that is convenient to disassemble. Background Art

[0002] A bearing is a commonly used rotating component in mechanical equipment, which is used to reduce the friction coefficient during the movement of the rotating body. Since the bearing is used very frequently, it is necessary to perform regular maintenance and component replacement; bearings are divided into many types. In the prior art, for some bearings, a locking sleeve needs to be sleeved on the rotating shaft first during installation, and then the bearing is sleeved on the locking sleeve. Finally, the bearing is fixed through some fixing components such as locking nuts. When it is necessary to perform maintenance or replace components on it, it is necessary to go through steps such as disassembling the locking washer, placing and hitting a steel pad, and then separately disassembling the bearing to replace the components. Finally, the installation steps need to be repeated, and the process is relatively cumbersome and not convenient enough;

[0003] During the disassembly and assembly process of the bearing, more tools are needed, and it is easy to cause damage to the bearing, making the disassembly inconvenient. Therefore, we propose a bearing that is convenient to disassemble. Content of the Utility Model
