Share the main structure and characteristics of the walking reducer

2025-07-04

The main transmission structure of the walking reducer is: planetary gear, sun gear, and external gear ring

Due to structural reasons, the minimum single-stage reduction for walking reducers is 3, and the maximum is generally not more than 10. The common reduction ratio is 3.4.5.6.8.10, and the number of reducer stages generally does not exceed 3. However, some customized reducers with large reduction ratios have 4 stages of reduction

Compared to other reducers, walking reducers have the characteristics of high rigidity, high precision (up to 1 point per stage), high transmission efficiency (97% -98% per stage), high torque/volume ratio, and lifetime maintenance free

Due to these characteristics, most walking reducers are installed on stepper motors and servo motors to reduce speed, increase torque, and match inertia The maximum rated input speed of the reducer can reach 18000rpm (depending on the size of the reducer itself, the larger the reducer, the lower the rated input speed). The output torque of industrial grade walking reducers generally does not exceed 2000Nm, and specially designed ultra high torque walking reducers can achieve over 10000Nm The working temperature is generally around -25 ℃ to 100 ℃, and its working temperature can be changed by changing the lubricating grease
