Why planetary reducer is the most precise reducer
Precision planetary reducer is another name for planetary reducer in the industry.
People in the industry know that the planetary reducer is a high-precision type reducer, which can be said to be the most precise reducer at this stage. But why can't other reducers achieve the precision of planetary reducers? Why can planetary reducers achieve such high precision?
Its main transmission structure is: planetary gear, sun gear, internal ring gear.
Compared with other reducers, precision planetary reducers have high rigidity, high precision (single stage can achieve less than 1 point), high transmission efficiency (single stage is 97%-98%), high torque/volume ratio, and lifetime maintenance-free Features. Most of them are installed on stepper motors and servo motors to reduce the speed, increase the torque, and match the inertia.
