Abstract

The invention discloses a small motor, which comprises a rotating shaft, a casing, a brush box and a pin. The rotating shaft is arranged at the center of the casing. The brush box is connected with the casing. The pin is arranged in the casing. The casing and the brush box are connected through thread. A baffle is arranged on the casing. The rotating shaft is provided with thread. The brush box is internally provided with a groove and a radiating fin. The groove is internally provided with thread matched with the thread on the rotating shaft. In the assembling, only the brush box is needed to be connected with the casing through the rotation of the thread, and then with the action of the pin, the brush box and the casing are fixed; and if the rotating shaft is needed to be replaced, only the pin is needed to be open to take off the brush box in a rotating manner, so that the complexity in assembling the casing and the brush box and tedious processes of difficult dismounting are tackled, the replacement and assembling of motor parts can be performed effectively and conveniently, and an occasion that a motor is damaged as the temperature of the motor is too high can be effectively prevented after the brush box is internally provide with the radiating fin.

Description

technical field [0001] The invention relates to a small motor. Background technique [0002] For traditional small motors, when replacing the shaft or brush box, it is often very cumbersome to disassemble the motor, and it is easy to cause damage to the motor. resulting in unnecessary losses. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a small motor that is easy to disassemble and assemble. [0004] The present invention is achieved through the following technical solutions: a small motor, including a rotating shaft, a casing, a brush box and a pin, the rotating shaft is arranged in the center of the casing, the brush box is connected with the casing, and the pin is arranged on On the casing, the casing and the brush box are connected through threads, the casing is provided with a baffle, the shaft is provided with threads, and the brush box is also provided with grooves and cooling fins. The groove is provided ...
