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. This innovative transmission mode breaks through traditional rigid component transmissions, offering unique functions difficult to achieve with other drives.
Harmonic Deceleration Principle
The deceleration principle of harmonic gear transmission involves the controlled elastic deformation of the flexwheel, rigid wheel, and wave generator to achieve motion and power transmission. Through the rotation of the elliptic CAM in the wave generator, the flexwheel constantly deforms, enabling active wave generator to flexwheel movement transmission.
