LHT/LHN/LHG Large Diameter Hollow Hole, Flat Shape Harmonic Gearbox

Zhejiang Laifual Drive Co., Ltd. is one of professional custom gear manufacturer. We provide LSD Shorten Thin Harmonic Gearbox, LFS Ultra Flat Harmonic Gearbox, harmonic gearheadand so on. Want to know more? Please contact us.

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 planetary 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.
