Industry insiders know that the planetary speed reducer is a high-precision gearbox, which can be said to be the most precise gearbox at this stage. But why can’t other reducer do the precision of planetary speed reducer? Why is the planetary reducer can do such a high degree of precision?
Its main transmission structure is: planetary wheel, sun wheel, internal gear ring.
Relative to other reducers, precision planetary reducers are characterized by high rigidity, high precision (single stage can be achieved within 1 minute), high transmission efficiency (single stage at 97%-98%), high torque/volume ratio, and lifelong maintenance-free. Most of them are installed on stepper motors and servo motors to reduce the speed, increase the torque and match the inertia.
Planetary gearmotors are also known as planetary speed reducers and servo speed reducers. In the family of reducers, planetary reducers are widely used in servo motors, stepper motors, DC motors and other transmission systems because of their small size, high transmission efficiency, wide range of deceleration, high precision and many other advantages. Its role is to ensure that the premise of precision transmission, mainly used to reduce the speed to increase the torque and reduce the load/motor moment of inertia ratio.
