Product Description

The combined harmonic reducer is a combined product with a component type as the core and equipped with precision and high rigidity cross roller bearings that directly support external loads. The harmonic gear adopts a sealed structure, which is convenient for assembly and application and can meet the needs of high performance, high speed, high load capacity, high density, and miniaturization. The service life is as long as 10,000 hours.  

Working Principle:

Before assembling, the flex-spline and its inner hole are circular. When the wave generator is installed in the inner hole of the flex-spline, the length of the wave generator is slightly larger than the diameter of the inner hole of the flex-spline. The wheel completely meshes with the fixed rigid wheel in the direction of the long axis of the ellipse, and completely separated in the direction of the short axis. Depending on the rotation position of the flexible wheel, the rest of the teeth are either in the "engaged" state or "engaged out" state.

Because the rigid wheel is fixed, when the wave generator rotates counterclockwise, the flexible wheel rotates clockwise. When the wave generator rotates continuously, the positions of the long and short shafts of the flex-spline and the "engaging in" and "engaging out" will continue to change. The teeth of the flex-spline change from engagement to engagement, and then engagement to engagement. The exit steering is disengaged, and the reciprocating cycle forces the flexible wheel to continuously rotate.

In the whole movement process, the deformation of the flex-spline is a continuous simple harmonic shape on the expanded view of the flex-spline circumference. Therefore, this transmission is called a harmonic drive gear transmission.
