Description

Technical Field

[0001] The utility model relates to the technical field of reduction motors, in particular to a transmission structure of a reduction motor. Background Art

[0002] A reduction motor is an integration of a reducer and a motor. The reducer can convert the high-speed input of the motor into a low-speed output through the reduction ratio. At the same time, it can provide a greater torque on the shaft without changing the power and keep the torque relatively stable. By reducing the speed of the motor through the reducer, more precise torque control can be achieved to meet a variety of application requirements.

[0003] During the operation of the reduction motor, when the motor starts running, the reducer reduces the speed of the motor input shaft through the meshing transmission of the gears, and increases the torque of the output shaft. The number of teeth of the driving gear and the driven gear are different, so the speed of the driven gear is reduced, and the torque of the output shaft is increased;

[0004] During the use of existing reduction motors, although the reducer can reduce the motor speed by the meshing rotation between gears, it causes a certain amount of energy loss during operation, which slightly reduces the transmission efficiency. The reducers of some reduction motors reduce the motor speed by the meshing rotation between bevel gears. Although this method improves the transmission efficiency, the installation work is relatively cumbersome because the bevel gears in the reducer have high requirements for installation accuracy. If the installation is not accurate, it may cause wear of the bevel gears and bearings, thereby affecting their performance and life. For this reason, we propose a transmission structure of a reduction motor. Utility Model Content

[0010] Furthermore, the transmission mechanism also includes a driving rod and a sun gear. The driving rod is rotatably connected to the middle part of the left wall of the mounting base through a bearing. The right end of the motor output shaft is fixedly connected to the left end of the driving rod. A sun gear is provided at the right end of the driving rod.
