Wanshsin WSHG-I/II
Harmonic Strain Wave reducer
- Harmonic gear - Wanshsin SHG-I/II
- Nominal torque up to 160 Nm
- 50:1 - 120:1 / 15-20 arcsec



The gears with output bearing of the WSHG series are ideal for highly dynamic applications, such as in robot axes. This is supported by: enormous torque density, high-tilt output bearing, lifelong precision and zero backlash.
The WSHG series is a compact gear unit based on the Harmonic strain wave principle. Generally, the circular spline end is fixed and the flex spline is the output rotating side.
WSHG-I:
The input motor shaft is directly connected to the harmonic gear unit by means of a hollow shaft with keyway.
WSHG-II:
The input motor shaft is connected to the hollow shaft of the harmonic gear unit by means of a coupling.
The WSHG gear unit has the same dimensions and specifications as the Harmonic Drive SHG series.
