What is a harmonic reducer and how does it work

A harmonic reducer is a type of gear reducer that uses flexible elements to achieve high reduction ratios in a compact package. It consists of three main components: a wave generator, a flex spline, and a circular spline.

The wave generator is a flexible ring with a series of specially shaped teeth that deform when it is rotated. The flex spline is a thin, flexible ring with internal teeth that mesh with the teeth on the wave generator. The circular spline is a rigid ring with external teeth that mesh with the teeth on the flex spline.

As the wave generator rotates, it causes the teeth on the flex spline to mesh with the teeth on the circular spline, creating a rolling motion that reduces the output speed and increases the output torque. Because the flex spline is so thin and flexible, it can bend and deform to accommodate the motion of the wave generator, which allows the system to achieve high reduction ratios (typically 30:1 to 300:1) in a very compact package.

Harmonic reducers are often used in robotics, automation, and other applications that require precise motion control, high torque density, and low backlash. They are also known for their high efficiency and accuracy, as well as their ability to operate at very low speeds without overheating or stalling.
