How does the harmonic reducer work

When harmonics are used as reducers, usually in the form of active wave generators, the circular spline and flex spline outputs are fixed.

When the wave generator is mounted to the inner ring of the Flex spline, it forces the flexspline to elastically deform and become elliptical, so that the flexspline teeth at the major axis are inserted into the gear grooves of the circular spline, which becomes Fully engaged state; although at the minor shaft, the gear teeth of the flex spline and circular spline are completely unaffected and disengaged.The process between engagement and disengagement is a state of engagement or engagement.When the wave generator rotates continuously, it forces the flex splines to deform, which makes the two splines change their working state during engagement, engagement, engagement and disengagement, resulting in the so-called astonishing tooth movement to realize the wave generator and Flex Motion transfer between splines.
