Pros and cons of worm gear reducer
The main feature of the worm gear reducer is the reverse self-locking function, which can be greatly reduced.
In the speed ratio, the input shaft and the output shaft are not on the same axis, nor on the same plane. However, the volume is generally large, the transmission efficiency is not high, and the accuracy is not high. The harmonic drive of the harmonic reducer uses the elastic deformation controlled by the flexible element to transmit motion and power. The volume is small and the precision is high, but the disadvantage is that the flexible wheel has limited life and is not impact resistant. The rigidity is compared with the metal parts. difference. The input speed cannot be too high. The planetary reducer has the advantages of compact structure, small return clearance, high precision, long service life and large rated output torque. But the price is slightly more expensive
