HMHG-I. series harmonic reducer
HMHG-I. series flexible pulley is a hollow flanging standard structure, with a large diameter hollow shaft hole in the middle of the wave generator cam, and a support bearing inside the reducer, which is fully sealed and easy to install, which is very suitable for the occasion of threading from the center of the reducer
Principle of Harmonic Gear Transmission
The harmonic gear drive, invented by C.W. Musser in 1955, utilizes the elastic deformation of flexible components for movement and power transmission. By breaking through traditional rigid component transmission, this drive achieves unique functions difficult to replicate with other methods.
Harmonic Deceleration Principle
The deceleration principle of harmonic gear transmission involves the controlled elastic deformation of the flexwheel to achieve motion and power transmission. Through the interaction of the flexwheel, rigid wheel, and wave generator, this transmission method enables continuous movement and transmission.
