High precision: multi-tooth meshing at two l80 degree positions at the same time, so the influence of gear pitch error and cumulative pitch error on rotation accuracy is relatively even, and extremely high position accuracy and rotation accuracy can be obtained.
Large transmission ratio: the transmission ratio of single-stage harmonic gear transmission can be selected I = 50~160, and the structure is simple.
High carrying capacity: In harmonic drive, the meshing of teeth and teeth is surface contact, and the number of meshing at the same time is relatively large, so the load per unit area is small and the carrying capacity is higher than other transmission forms.
Small size and light weight: Compared with ordinary gear devices, the volume and weight can be greatly reduced, realizing miniaturization and light weight.
High transmission efficiency and long life
Smooth transmission, no impact, low noise
