Product Description
The model 8 and model 11 harmonic drive of LS and LH series are known as the mini-shaped strain wave reducer.
LS And LH series miniature strain wave reducers provide high positioning accuracy in a very compact package.
These mini strain wave gears harmonic drive are well suited for semiconductor and robotics applications, especially end of arm axes for small industrial and collaborative robots, industrial machinery where weight is a critical factor.
How it Works
The Flexspline is slightly smaller in diameter and has two fewer teeth than the Circular Spline. The elliptical shape of the Wave Generator causes the teeth of the Flexspline to engage the Circular Spline at two opposite regions across the major axis of the ellipse. For every 180 degree clockwise rotation of the Wave Generator the Flexspline teeth are advanced counterclockwise by one tooth in relation to the Circular Spline. Each complete clockwise rotation of the Wave Generator results in the Flexspline moving counter-clockwise by two teeth from its original position relative to the Circular Spline.
Key Features
Ultra-Flat Design The Miniature series offers an ultra-flat harmonic drive design, ensuring compatibility with space-constrained applications.
Lightweight Construction Designed with lightweight materials, the Miniature series minimizes overall weight without compromising performance.
Compact Size With a small form factor, the Miniature series harmonic drive is ideal for applications where size constraints are a concern.
High-Rigidity Cross Roller Bearing Utilizing high-rigidity cross-roller bearings, the Miniature series ensures smooth and precise motion control, enhancing overall performance.
Highest Input Characteristics The integrated strain wave reducer, combined with a high-performance small motor, provides the Miniature series with the highest input characteristics under the same gear conditions, ensuring optimal efficiency and reliability.
