HHT Series Harmonic Drive Gearbox Φ70mm Ratio 100:1 Backlash 20arcsec 14mm Input Diameter

This harmonic gearbox has a gear ratio of 100, a frame size of Φ70mm and an input shaft diameter of 14mm and a maximum backlash of 20arcsec.
The HHT series harmonic gearboxes feature in integrated wave generator, large diameter hollow shaft hole and compact structure. The flexspline and the rigid spline are connected through high-rigidity cross bearings, making it an easy-to-operate modular product. It can be fixed at either end, rigid or flexible, for output connection.
Characterized by an ultra-flat design, lightweight, and compactness, this series is widely used in humanoid robots, metal machine tools, medical equipment, communication equipment, etc.
