AI Technical Summary
Existing bearing disassembly tools cause uneven force on the bearing circumference during disassembly, which can easily lead to damage to the motor rotor or damage to the bearing.
A bearing disassembly fixture was designed, including a positioning mechanism and a pushing mechanism. The movement of the bearing is restricted by the positioning channel and the thrust surface, and the rotor is pushed axially along the positioning channel by the pushing component to ensure that the bearing is subjected to uniform force.
During bearing disassembly, the bearing circumference is evenly stressed, preventing damage to the motor rotor and bearing damage. This method is suitable for disassembling bearings of different motor models.

Abstract
Claims
1. A bearing dismounting tool, characterized in that, include: The positioning mechanism includes two positioning seats that are detachably and fixedly connected to form a columnar positioning channel. A thrust surface is formed on the side of one end of the positioning channel. The positioning channel is used for the rotor of the motor to slide through. During this process, the thrust surface abuts against the bearing on the rotor. A pushing mechanism, disposed on the thrust surface, is used to abut against the end of the rotor to push the rotor through the positioning channel.
2. The bearing disassembly tool of claim 1, wherein, The pushing mechanism includes a mounting plate, a mounting shaft, and a pushing assembly. The mounting shaft is coaxially arranged with the positioning channel and is detachably fixedly connected to the mounting plate. The pushing assembly is connected to the mounting shaft and corresponds to the positioning channel. The pushing assembly has a fixed state that is fixedly connected to the mounting shaft and an active state that can move axially along the mounting shaft to push the rotor to move axially along the positioning channel.
3. The bearing disassembly tool of claim 2, wherein, The mounting shaft has a threaded hole extending along its axial direction. The pushing assembly includes a first screw and a handwheel. The first screw passes through the threaded hole and is threadedly connected to the threaded hole. The handwheel is fixedly connected to the end of the first screw away from the positioning mechanism.
4. The bearing disassembly fixture according to claim 1, characterized in that, It also includes an installation mechanism, which includes two mounting seats. The two positioning seats are detachably and fixedly connected to the two mounting seats in a one-to-one correspondence. The two mounting seats are arranged vertically and are detachably and fixedly connected so that the two positioning seats form the positioning channel. One side wall of the two positioning seats forms the thrust surface.
5. The bearing disassembly tool of claim 1, wherein, It also includes a support mechanism, which is located at the other end of the positioning channel and can move up and down to support the motor.
6. The bearing disassembly tool of claim 5, wherein, The support mechanism includes a support base and a lifting assembly. The lifting assembly is connected to the support base and is used to drive the support base to move up and down so that the support base supports the motor.
7. The bearing disassembly tool of claim 1, wherein, The diameter of the positioning channel is equal to the diameter of the motor rotor.
8. The bearing disassembly tool of claim 1, wherein, The positioning channel is set horizontally, and the thrust surface is set vertically.
9. The bearing disassembly tool of claim 8, wherein, The positioning mechanism includes multiple mechanisms, and the diameter of the positioning channel in each positioning mechanism is different.
10. The bearing disassembly tool of claim 9, wherein, The two positioning seats are arranged one above the other, and each of the two positioning seats has a positioning groove. Both positioning grooves are semi-cylindrical structures. When the two positioning seats are detachably and fixedly connected, the two positioning grooves form the positioning channel, and one side wall of the two positioning seats forms the thrust surface.
