HHT Series Harmonic Drive Gearbox Φ80mm Ratio 100:1 Backlash 20arcsec 8mm Input Diameter

This harmonic gearbox has a gear ratio of 100, a frame size of Φ80mm and an input shaft diameter of 8mm and a maximum backlash of 20arcsec.
The HHT series harmonic gearboxes feature in integrated wave generator with it's own input shaft 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.
