The concept of planetary reducer

来源: 发布日期:2011-5-6 17:45:43

One: the number of stages  

Number of stages: the number of planetary gears. Since one set of planetary gears cannot meet the larger transmission ratio, sometimes 2 or 3 sets are needed to meet the user's requirements for larger transmission ratios. Due to the increase in the number of planetary gears, the second level Or the length of the 2-stage reducer will increase, and the efficiency will decrease.  

Two: Return clearance:  

Return clearance: Fix the output end and rotate the input end clockwise and counterclockwise to make the input end produce rated torque +-2% torque, there is a slight angular displacement at the input end of the reducer, and this angular displacement is the return clearance. Unit It is a "point", which is one-sixtieth of a degree. Some people call it backlash.  

The main transmission structure is: planetary gear, sun gear, and outer ring gear.  

Due to the structure of the planetary reducer, the single-stage reduction is 3, generally not more than 10, and the common reduction ratio  


Because of these characteristics, planetary reducers are mostly installed on stepper motors and servo motors to reduce speed, increase torque, and match inertia.
