Method and device for assembling gear motor, and gear motor

Abstract

The invention discloses a method and device for assembling a gear motor and a gear motor. The method and the device are used for assembling the driving gear and the driven gear of the gear motor. Themethod comprises the following steps that: the driving gear is made to rotate; and the driven gear and the driving gear are made to approach to each other along an axial direction, so that the gear teeth of the driven gear are plugged into the tooth slots of the rotating driving gear, and therefore, the full engagement of the driving gear with the driven gear can be realized. With the method and device of the present invention adopted, damage caused collision between the driving gear and the driven gear can be alleviated, gear damage caused during the assembly process of the gear motor, especially the assembly process of the driving gear and the driven gear can be greatly reduced, and the assembly quality of the gear motor can be ensured.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a method for assembling a gear motor, equipment using the method and a gear motor assembled by the method. Background technique [0002] A gear motor (also called a gear variable speed motor) is a motor widely used in the market today, which includes a motor part and a variable speed gear part. The motor part includes a motor body and an output shaft. The output shaft rotates at a high speed driven by the rotor of the motor body. The speed change gear part has gear pairs with different meshing forms according to the requirements of different speed ratios. Usually, each gear pair of the variable speed gear part includes a driving gear installed on the motor shaft and a driven gear meshed with the driving gear. The driving gear rotates under the drive of the motor shaft and drives the driven gear meshed with it to rotate, thereby driving The other gears in the transmission gear sec...

AI Technical Summary

Problems solved by technology

[0004] In the existing above-mentioned assembly method, there are the following defects: for smaller motors, especially stepping motors, the size of each gear is small, and at the initial stage of making the driving gear mesh with the driven gear, the wheel of the driven gear The teeth and the tooth grooves of the driving gear may not be aligned exactly, so that the driving gear and the driven gear collide severely, resulting in gear damage.
