2025 Top 10 Harmonic Drive Factory in China

Introduction to Harmonic Drive

Harmonic drive, also known as harmonic drive gearing, is a unique type of mechanical drive system. It was invented by C.W. Musser in 1957. The basic structure of a harmonic drive consists of three main components: a wave generator, a flexspline, and a circular spline.

The wave generator is usually an elliptical cam with a ball - bearing race, which is inserted into the flexspline. When the wave generator rotates, it deforms the flexspline into an elliptical shape. The flexspline is a thin - walled, flexible gear with external teeth, while the circular spline is a rigid gear with internal teeth. The difference in the number of teeth between the flexspline and the circular spline creates a speed - reduction effect.

Harmonic drives offer several advantages over traditional gear systems. They have high reduction ratios in a compact size, high torque transmission capabilities, zero backlash, and high positional accuracy. These features make them widely used in various fields such as robotics, aerospace, precision machinery, and medical equipment.
