LHD Speed Reduction Industrial Robot Harmonic Driver
-Principle of harmonic gear reducer
I.Harmonic gear reducer has three basic components : a wave generator , a flexspline and a circular splineWave generator : it is made up of a ball bearing and an elliptical cam . The wave generator is usually attached to the input end , theinner ring of the bearing is fixed around the cam causing the outer ring of the bearing deforms to an elliptical shapeFexspline : it is an elastic thin-walled component with gear teeth on outer surface . It is usually fitted to output endCircular spline : it is a rigid steel ring with internal teeth . It usually has two more teeth than the flexspline , and generally mountedonto a housing
II. As a reducer , the harmonic gear reducer is often in a status as : the wave generator drives , the circular spline is fixed , the flexsplineis output endWhen the wave generator is put inside of the flexspline , the flexspline is forced into an elliptical shape causing the flexspline teethto engage with the tooth profile of the circular spline along the major axis of the ellipse , with the teeth completely disengagedacross the minor axis of the ellipseengagement and disengagement , thus the motion transmission between wave generator and flexspline is realize aThe rotation of the wave generator makes the flexspline deform continuously ,
III.The teeth change operating state in the process of Characteristics of harmonic gear reducer
1 . High accuracy : a good percentage of its teeth are meshed at all times , and are engaged at two zones 180 degrees apart . Thismeans influences of tooth pitch errors and accumulated pitch errors on rotational accuracy are neutralized , which assures highpositional and rotational accuracy
2 . High speed reduction ratio : a harmonic gear reducer has high single-stage reduction ratios of 1 / 30-1 / 500 . Three basic compo -nents along same axle without complex structures can provide high reduction ratios
3 . High torque capacity each tooth is subjected to a negligible amount of force yet provides a high torque capacity because of theway the teeth come into contact with each other and because a good percentage of the teeth in the flexspline are engaged at altimes
4 . Small-sized and light weight : while being less the size of conventional gearing mechanisms and less the weight , the harmonicgear reducer provides the same levels of torque and speed reduction ratios as its conventional counterparts enabling machineryand equipment to be made smaller and lighter .
5 . Superior efficiency and long life time6 . Quiet and minimal vibration operation
