Planetary reducer main structure and characteristics

The main transmission structure of the planetary reducer is:

Planetary gear, sun gear, outer ring gear. Due to structural reasons, the planetary gear reducer has a minimum of 3 for single-stage deceleration and a maximum of 10 for maximum. The common reduction ratio is 3.4.5.6.8.10, and the number of gearboxes is generally not more than 3. However, there are some large reduction ratios than the custom reducer has 4 stages of deceleration. Compared with other reducers, the planetary reducer has high rigidity, high precision (single level can be less than 1 point), high transmission efficiency (single stage at 97%-98 %), high torque/volume ratio, lifetime maintenance-free features.

Features:

Planetary reducers are mostly installed on stepper motors and servo motors to reduce the speed, increase the torque and match the inertia. The rated input speed of the reducer can reach up to 18000 rpm (depending on the size of the reducer itself, the larger the reducer, the rated input The smaller the speed, the above, the output torque of the industrial grade planetary reducer is generally not more than 2000Nm, and the special super-torque planetary reducer can achieve more than 10000Nm. The working temperature is generally around -25°C to 100°C. The work can be changed by changing the grease. temperature.
