HST-I harmonic drive reducer from China manufacturer tells you that harmonic transmission reducer is mainly composed of four basic components, a wave generator, flexible gear, flexible bearing, and rigid gear. HST-I harmonic drive reducer from China manufacturer tells you that harmonic drive reducer is a kind of wave generator equipped with flexible bearings to make flexible gears produce controllable elastic deformation, and mesh with rigid gears to transmit motion and power gear drive.

Next, this article will tell you in detail the working principle of the harmonic drive reducer. HST-I harmonic drive reducer from China manufacturer tells you that the generator installed in the flex spline makes the flex spline radially deformed into an oval shape. 
At this time, HST-I harmonic drive reducer from China manufacturer tells you that on the major axis of the ellipse, the teeth engage along the entire working height, while On the minor axis, radial clearances are formed between the tooth tips. During the rotation of the generator, the shape of the flex spline is always close to the above-mentioned shape.
Through the above introduction and analysis of the HST-I harmonic drive reducer from China, hope it helps you.
