RHSG Hat-shaped Strain Wave Gear
Harmonic gear transmission principle
Harmonic gear transmission was invented by American inventor C.W. Musser in 1955. It is a new type of transmission method that uses the elastic deformation of flexible components for motion or power transmission, which breaks through the mode of mechanical transmission using rigid component and uses a flexible component to realize mechanical transmission, thus obtaining a series of special functions that are difficult to be achieved by other transmissions. Its name comes from the fact that the deformation process of the middle flexible component is basically a symmetrical harmonic. In addition to the Soviet Union, this kind of transmission is called wave transmission or flexspline transmission, the United States, Britain, Germany, Japan and other countries are called "harmonic transmission".
Advantages
Harmonic gearing has some advantages over traditional gearing systems:
No backlash
Compactness and light weight
High gear ratios
Reconfigurable ratios within a standard housing
Good resolution and excellent repeatability (linear representation) when repositioning inertial loads
High torque capability
Coaxial input and output shafts
High gear reduction ratios are possible in a small volume
Applications
Strain wave gears are widely used in robots, humanoid robots, aerospace, semiconductor manufacturing equipment, laser equipment, medical equipment, metal processing machinery, drone servo motor, communication equipment, optical equipment, etc.
