A good percentage of harmonic gear reducer's teeth are meshed at all times and are engaged at two zones 180 degrees apart. This means influences of tooth pitch errors and accumulated pitch errors on rotational accuracy are neutralized, which assures high positional and rotational accuracy.
As a professional harmonic drive gearbox company and strain wave gear manufacturer in China, Hanzhen harmonic drive reducers with superior harmonic drive efficiency and long service time.
While being less the size of conventional gearing mechanisms and less the weight, the strain wave reducer provides the same levels of torque and speed reduction ratios as its conventional counterparts enabling machinery and equipment to be made smaller and lighter.
A harmonic gear reducer has high single-stage reduction ratios also known as harmonic drive gear ratio or harmonic drive ratio of 1/30-1/500. Three basic components along same axle without complex structures can provide high reduction ratios.
Each tooth subjected to a negligible amount of force yet provides a high torque capacity because of the way the teeth come into contact with each other and because a good percentage of the teeth in the flex spline is engaged at all times.
Hanzhen harmonic drive reducers also operate with quiet and minimal vibration.
