HHT Series Harmonic Drive Gearbox Φ170mm Ratio 50:1 Backlash 20arcsec 19mm Input Diameter

This harmonic gearbox has a gear ratio of 50, a frame size of Φ170mm and an input shaft diameter of 19mm and a maximum backlash of 20arcsec.
The HHT series harmonic gearboxes feature in integrated wave generator 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.

Key Feartures
