Abstract
A harmonic drive includes a circular spline, a flexspline meshed with the circular spline, and a wave generator abutted against the flexspline. Through a special parameter design to correct the perimeter curve of the wave generator, the meshing efficiency between the circular spline and the flexspline is increased, thereby improving the transmission accuracy and reducing the average load.
