LHT/LHN/LHG Large Diameter Hollow Hole, Flat Shape Harmonic Gearbox
The LHT Series of hollow output shaft gearboxes use hat type flex spline. We can divide the LHT drive actuators into 5 versions, LHT-I, LHT-II, LHT-III, LHT-IV and LHT-V.
Differences Among Different LHT Hollow Shaft Gearbox:
LHT-I: use uni-body type wave generator
LHT-II: cross slider type wave generator
LHT-III: large bore with a hollow hole
LHT-IV: shaft input type
LHT-V: Simple type
Applications of LHT Harmonic Drive Actuators:
Industrial robots;
Service robots;
Medical Devices;
Automation and special equipment;
Printed circuit manufacturing equipment.
