what is harmonic drive precision gear reducers?
Harmonic Drive precision gear reducers are a type of highly accurate and compact gear mechanism widely used in applications requiring precise motion control, such as robotics, aerospace, and automation. They are known for their unique design, which consists of three key components: the wave generator, the flex spline, and the circular spline.
Wave Generator: Shape of the thin ball-bearing-supported disk used in wave generators is elliptical. It deforms the flex spline specifically to interact with the circular spline in designated locations.
Flex Spline: Less teeth than the circular spline, this flexible, thin-walled cylindrical gear fits inside the circular spline. The flex spline shapes itself to correspond with the form of the wave generator.
Circular Spline: The circular spline interacts with the flex spline like a rigid gear with internal teeth. The large reduction ratio is made possible by the minor variation in tooth count between the flex and circular spline.
what are the Features of Harmonic Drive?
High reduction ratio: Harmonic drive can achieve very high reduction ratio through special flexible gear structure, usually 50:1 to 300:1, or even higher.
