The gear unit of the HCS-I series Harmonic Drive Reducer adopts a unique working principle based on metal elastic mechanics. Compared with other gears, the biggest advantage of the gears of the HCS-I series Harmonic Drive Reducer is the zero backlash characteristics, as well as the saving of weight and space, because this gear mechanism consists of only three basic parts. They are Wave Generator, Flex spline, and Circular Spline.

Main components of the HCS-I series Harmonic Drive Reducer. This simple three-element structure combined with a unique operating principle enables extremely high reduction ratios in a very compact and lightweight housing.
The size and weight of the gears of the HCS-I series Harmonic Drive Reducer do not vary with the reduction ratio. The high-performance attributes of this gear technology, including zero backlash, high torque, compact size, excellent positioning accuracy, and repeatability, are the result of a unique operating principle.
Through the above introduction and analysis of the Gear of HCS-I series Harmonic Drive Reducer, hope it helps you.
