Introduction to Harmonic Drive
Harmonic drive, also known as harmonic drive gearing or strain - wave gearing, is a unique type of mechanical gear system. It was invented by C. Walton Musser in 1957. The basic principle of a harmonic drive involves three main components: a wave generator, a flexspline, and a circular spline.
The wave generator is usually an elliptical cam with bearings. When it rotates, it deforms the flexspline, which is a thin - walled, flexible gear. The circular spline is a rigid outer gear with a slightly different number of teeth compared to the flexspline. As the wave generator rotates, the teeth of the flexspline engage and disengage with the teeth of the circular spline at different positions, resulting in a large reduction ratio in a compact and lightweight package.
Harmonic drives are widely used in various industries such as robotics, aerospace, medical equipment, and precision machinery. Their advantages include high reduction ratios, zero backlash, high torque - to - weight ratios, smooth operation, and high positioning accuracy.
