[0002] Motor bearings, also known as motor bearings or motor bearings, are a type of special bearing specifically applied to electric motors or motors. Motor bearings are components that support the motor spindle and guide its rotation, and at the same time bear the load generated by the motor to ensure that the motor can operate smoothly and efficiently.

[0003] One of the existing conventional bearing disassembly methods is to use a puller (bearing disassembly tool) to disassemble the bearing, but the thickness of the claws of the puller is relatively thick, and the required space is relatively large, which does not meet the working conditions requirements and cannot be disassembled; another method is to lock the bearing and the flange, and disassemble the bearing by supporting the flange, but it is easy to damage the flange, and at the same time the disassembly effect is not ideal, resulting in waste; so we propose a mechanism for disassembling bearings at an extremely small spacing to facilitate solving the problems raised above.
