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 harmonic reducers:
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
|Model||Reduction ratio||Rated torque at 2000r/min input||Permissible peak torque at start and stop||Permissible maximum value for average load torque||Permissible maximum momentary torque||Permissible maximum input rotational speed（Grease）||Permissible average input rotational speed|
Large bore with hollow hole, flat shape
High positioning and rotational accuracies
Coaxial input and output
Compact and simple design
High torque capacity
LHT-I/II Series Harmonic Drive Gearbox
The wave generator adopts an integrated structure, which makes the whole product structure more compact.
Two connection ways：Circular spline is fixed while flexspline as an outputs. Or flexspline is fixed while circular spline as an outputs
Motor can be connected with the gearbox directly. It is easy for installation.
LHT-III Series Harmonic Gearbox
There is a large-diameter hollow shaft hole in the middle of the wave generator cam
There are support bearings inside the harmonic gearbox. The harmonic reducer is designed with fully sealed structure. It is easy for installation
It is suitable for situation where the wire needs to be threaded from the center of the harmonic gearbox
LHT-IV Series Harmonic Drive
The wave generator cam comes with input shaft. It is suitable for different input forms.
There are support bearings inside the strain wave gear. The harmonic gearbox is designed with fully sealed structure. It is easy for installation
It is suitable for situation where bevel gears or timing belt drive need to be installed at the input end
LHT-V Series Strain Wave Gear
Based on LHT-III series harmonic drive gearbox, users can redesign freely for lower weight and thinner thickness while properties have no change.
