Tool for disassembling motor rotor

The utility model relates to a tool for disassembling a motor rotor, which relates to the technical field of motor maintenance and comprises a first sleeve arranged on the motor rotor in a sleeving manner, a connecting frame arranged on the first sleeve and used for driving the first sleeve to move along the axis direction, and a connecting piece arranged on the connecting frame and used for connecting a crane. According to the application, the lifting hook of the gantry crane is fixedly mounted on the connecting piece, the connecting frame and the first sleeve are moved to the position of the motor rotor by the gantry crane, then the motor rotor is sleeved with the first sleeve, and the gantry crane ascends by a certain distance after the mounting is completed, so that the motor rotor is fixed in the first sleeve in an abutting manner; the crane drives the motor rotor to move in the direction away from the motor, and finally the motor rotor is stably taken away from the motor, so that collision generated whe
