[0001] The utility model relates to the technical field of motor shafts, in particular to a motor shaft which is easy to assemble and disassemble. Background Art

[0002] The motor shaft is a mechanical device. The strength and rigidity of the motor shaft are guaranteed. When the motor is running, the mechanical force and torque on the shaft vary with the type of motor and the transmission mechanism. The main forces are: the gravity of the rotor assembly itself, the one-way impact force caused by the eccentricity of the rotor, and the centrifugal force of the unbalanced weight. The load torque acting on the shaft by the transmission machinery at the shaft extension end, etc., the motor shaft will inevitably be damaged during long-term use.

[0003] Prior art, such as patent publication number CN220668311U records a motor shaft that is easy to install and disassemble, including a shaft body and a side shaft, a slot is provided at one end of the shaft body, a plug rod is fixed at one end of the side shaft, and the plug rod is arranged in the slot, a limiting hole is provided on one side of the plug rod, and plug holes are provided on both side walls of the slot, arc plates are provided on both sides of the shaft body, limiting rods are fixed on the side walls of the two arc plates, and the limiting rods pass through the plug holes and are inserted in the limiting holes, annular sleeve plates are fixed on both sides of the side walls of one of the arc plates, and slide plates are fixed on both sides of the side walls of the other arc plate, the motor shaft consists of the shaft body and the side shaft, when the side shaft is damaged and needs to be replaced, the arc plate is pulled to pull the limiting rod out of the limiting hole, and then the plug rod is taken out of the slot, which facilitates the disassembly of the motor shaft.

[0004] In actual use, after removing the side shaft and replacing it with a new one, it is necessary to align the side plug plate with the side slot, insert the plug rod into the slot, insert the limit rod into the limit hole, connect the arc plate with the slide plate and the annular sleeve plate, and fix it with a fixing mechanism. The replacement and installation process is relatively cumbersome and time-consuming. After the motor shaft is damaged, it must be replaced as soon as possible so that the motor can continue to be used.
