Planetary gear motor function, categories and characteristics

Jun 19, 2018

With excellent performance, planetary gear motors have been widely used. At present, we can directly install planetary gear motors to AC and DC servo motors, which are widely used in industrial fields with medium accuracy. Such as printing machine tools, flame cutting, laser cutting, CNC machine tools, tool machinery, food packaging, automation industry.


1, the main role of planetary gear motor:

About the role of the motor can be divided into two main aspects, one is to reduce the speed and increase the output torque, torque output ratio by motor output by the reduction ratio, but be careful not to exceed the rated torque of the reducer. Another role is to reduce the inertia of the load while reducing the speed, and the reduction in inertia is the square of the reduction ratio. Usually the motor has an inertia value.


2. What kinds of planetary gear reduction motors are included:

For now, common reducers include helical gears, precision planetary gears, servo-specific planetary gears, right-angle planetary gears, planetary gears, helical gears, powerful gears, precision gears Machine, cycloid reducer, worm gear reducer, planet friction type mechanical continuously variable speeder and so on.


In addition, it can be classified according to other methods, for example, according to the level can be divided into three categories. According to the purpose can be divided into military and civilian use; according to the different working environment, it can be divided into standard environment, low temperature environment, clean room environment and vacuum environment; according to the accuracy of points, including the standard accuracy and high precision and super-precision level and so on.


3, the main performance characteristics of planetary gear motor

Planetary gear motor has many advantages such as high cost performance, wide application, long service life and so on. Accurate positioning control, in the operating platform with low backlash, high efficiency, high input speed, high input torque, smooth operation, low noise and other features, appearance and structural design of light. And the structure is more compact, the backlash is small and the precision is high.
