Description of LHG Harmonic Gear Reducer

High torque harmonic drive gearbox. Compared with standard products, LHG series' torque capacity is 30% higher. We use the self-developed CMP heat treatment process to change the organizational form, refine organizational grains, strengthen the material properties, improve the tensile strength, yield strength and other indicators to change the mechanical properties of the material, so as to enhance the overall service life and improve the torque capacity of the harmonic gearbox.

LHG-I/II High Precision Harmonic Gearbox

The wave generator adopts an integrated structure, which makes the whole product structure more compact.
Two connection ways：Circular spline is fixed while flexspline as an outputs. Or flexspline is fixed while circular spline as an outputs
Motor can be connected with the gearbox directly. It is easy for installation

LHG-III High Reliability Harmonic Drive Gearbox

There is a large-diameter hollow shaft hole in the middle of the wave generator cam
There are support bearings inside the harmonic gearbox. The harmonic reducer is designed with fully sealed structure. It is easy for installation.

LHG-IV High Torque Strain Wave Gear

The wave generator cam comes with input shaft, and it’s suitable for different input forms.
There are support bearings inside the strain wave gear. The harmonic gearbox is designed with fully sealed structure. It is easy for installation.

LHG-V Large Speed Ratio Harmonic Gearbox

Based on LHG-III series harmonic drive gearbox, users can redesign freely for lower weight and thinner thickness while properties have no change.
