DSH-PO Series
Strain Wave Gear with Self-Aligning Input (Oldham Combination Type)
DATORKER® Strain Wave Gearing Systems
DGH-PO Series
DGH-PO Heavy Load Combination Strain Wave Gear, Oldham Input
- Type
- Combination unit (PO) with crossed roller bearing, Oldham input
- Models
- 14 - 40 (6 sizes)
- Reduction Ratios
- 50 - 160
- Rated Torque
- 7 - 382 Nm
The DGH-PO combines the heavy-load DATORKER gearset (a hollow type flex spline driven by the wave generator inside a ring type circular spline, for high reduction ratios in minimal space) with a 30% higher torque load than the standard series. The unit comes assembled and lubricated, crossed roller bearing included. Its input self-aligning shaft compensates motor mounting error, and the assembly withstands axial and radial loads.

Models & ratios
Rated torque is at 2,000 rpm input; peak torque covers start and stop. Ratios step up with size: model 14 runs 50 to 100, model 17 adds 120, and models 20 to 40 run the full 50 to 160 spread.
