Common reducer types

(A) Helical Worm Geared Motors harmonic transmission is the use of flexible components to control the elastic deformation to transfer movement and power, the volume is not large, high precision, but the disadvantage is the limited life of the flexible wheel, impatience impact, rigidity and metal Pieces are relatively poor. The input speed can not be too high.
(B) planetary reducer has the advantage of relatively compact structure, small return gap, high precision, long life, rated output torque can be done very large. But the price is slightly expensive
(C) cycloidal speed reducers is characterized by a reverse self-locking function, you can have a larger reduction ratio, the input shaft and output shaft is not on the same axis, nor in the same plane. But the general volume is larger, the transmission efficiency is not high, the accuracy is not high.
