The main feature of the worm gear reducer is that it has reverse self-locking function and larger gear ratio. The input shaft and output shaft are not on the same axis or same plane level. But generally it is big size, and the transmission efficiency & accuracy is not high.
The harmonic drive uses the controllable elastic deformation of the flexible element to transmit motion and power. It is small and the accuracy is high, but the disadvantage is that the flexible wheel has limited lifespan and not impact resistant. The rigidity is lower than metal parts’. The input speed cannot be too high.
The advantages of planetary reducer include compact structure, small return gap, high accuracy, long lifespan, and large rated output torque. But price is more higher.
The gear reducer has small size and large transmission torque. It is designed and manufactured on the basis of a modular combination system. The gear reducer has multiple motor combinations, installation and structural solutions, and the transmission ratio is finely graded to meet different working conditions to realize electromechanical integration. The gear reducer has high transmission efficiency, low energy consumption and superior performance.
The cycloidal pin gear reducer is one transmission model that adopts the principle of cycloidal pin tooth meshing planetary transmission. It is an ideal transmission device having wide range of advantages, and it can run forward and backward.
