Application

LeaderDrive utilize high-precision, zero-backlash harmonic drive precision gears and play critical roles in robotics, semiconductor manufacturing equipment, factory automation equipment, medical diagnostics and surgical robotics. Additionally, our products are frequently used in mission-critical scientific research projects which capture the human spirit.

Structure

Utilizing a unique operating principle, the gear consists of only 3 basic parts (Wave Generator, Flexspline, and Circular Spline). It provides excellent features not found in other speed reducers.

Wave Generator

The wave generator is a thin raced ball bearing fitted onto an elliptical hub. This serves as a high efficiency torques converter and is generally mounted onto the input or motor shaft.

Flexspline

The Flexspline is a non-rigid, thin cylindrical cup with external teeth on the open end of the cup. The Flexspline fits over the wave generator and takes on its elliptical shape. The Flexspline is generally used as the output of the gear.

Circular Spline

The circular spline is a rigid ring with internal teeth. It engages the teeth of the Flexspline across the major axis of the Wave Generator ellipse. The circular spline has two more teeth than the Flexspline and is generally mounted onto a housing.

Operating Principle

The flexspline is slightly smaller in diameter than the Circular Spline and usually has two fewer teeth than the wave generator. 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.

As the Wave Generator rotates the teeth of the Flexspline engage with the Circular Spline at the major axis. For every 180-degree clockwise movement of the Wave Generator the Flexspline rotates counter-clockwise by one tooth in relation to the Circular Spline.

Each complete clockwise rotation of the wave generator results in the Felxspline moving counter-clockwise by two teeth from its original position relative to the Circular Spline.
