LSG High Torque Harmonic Drives

Compared with the LSS series, LSG harmonic reduction gear has the same dimension as LSS harmonic speed reducers, but we improved the hardness of flex spline, using different heat treatment methods. We also added the contacting area of gear parts to reach 30% higher torque capacity, so the service life of the LSG series of micro harmonic drive can also increase by 43%.

Description of LSG Harmonic Drive Reducer

High torque harmonic gearbox. Compared with LSS series, LSG series' torque capacity is 30% higher, and the service life is increased by 43%. 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 performance of the harmonic gearbox.


  • The flexspline is a cup-shaped structure, and assembled with high-rigidity cross roller bearings

  • LS tooth profile design. Self-developed CMP heat treatment process. 1um locus fine grinding

  • Compact and simple design. Non-backlash. Motor can be connected directly. It is easy for installation

  • Input and output coaxial

  • Excellent positioning accuracy and rotation accuracy
