Deformation Investigations on the Flexspline with the Conic Curve Combined Cam Wave Generator
The deformation of the flexspline and the meshing quality are largely determined by the profile of a wave generator. The wave generator with a combined profile can effectively reduce or improve the deformation stress and strain of the flexspline for improving the transmission efficiency and reducing wear or noise.
