LFS Ultra Flat Harmonic Gearbox

LHD Shorten Thin Harmonic Gearbox

Harmonic gear reducer has three basic componentsa wave generator,a flexspline and a circular spline.

It is made up of a ball bearing and an elliptical cam. The wave generator is usually attached to the input end, the inner ring of the bearing is fixed around the cam causing the outer ring of the bearing deforms to an elliptical shape.

It is an elastic thin-walled component with gear teeth on the outer surface. It is usually fitted to the output end.

It is a rigid steel ring with internal teeth. It usually has two more teeth than the flex spline, and generally mounted onto a housing.

As a reducer, the harmonic gear reducer is often in status as the wave generator drives, the circular spline is fixed, and the flex spline is output end.

Characteristics of Harmonic Gear Reducer

A good percentage of its 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.

A harmonic gear reducer has high single-stage reduction ratios 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.

While being less the size of conventional gearing mechanisms and less the weight, the harmonic gear 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.
