The harmonic reduction gear has widespread applications in precision positioning systems. Its high precision, large reduction ratio, and lightweight characteristics make it a key component in achieving precise positioning. This article analyzes the application of the harmonic reduction gear in precision positioning systems.
Working Principle
A harmonic reduction gear consists of a rigid gear (internal teeth), a flexible gear (external teeth), and a harmonic generator. The flexible gear is placed inside the rigid gear, and the harmonic generator is situated within the flexible gear. Under the influence of the harmonic generator, the flexible gear deforms into an elliptical shape, with the teeth at both ends of the long axis fully meshing with the rigid gear, while the teeth at the short axis disengage. The remaining teeth are either engaged or disengaged depending on the direction of rotation. Since the flexible gear has two fewer teeth than the rigid gear, when the harmonic generator continuously rotates, the meshing areas will change in sequence with the phase shift of the long and short axes of the ellipse. As a result, the flexible gear rotates in the opposite direction of the rigid gear at a low speed.
