Main Features

High Precision Gear
Many teeth in the position of the two 180-degree symmetry Joggle.Gear tooth pitch error and the cumulative influence of pitch error on rotation accuracy is average. Very high position accuracy and running accuracy can be obtained.

High Ratio
Single harmonic drive gear ratio of up to i=30 to 500. Simple structure, three basic components on the shaft can be achieved with high reduction ratios.

High Load Capacity
Harmonic drive, tooth and meshing of the teeth is the contact, together with colleagues more meshing number of teeth, thus the load per unit area is small. Higher load capacity than other forms of transmission.
