This paper is on a rigorous definition and parametric study of tooth surface modification of the strain wave gear. You will see that optimal modification for a sample strain wave gear is found from FEA and tested by contact pattern, transmission error, and life cycling experiments. The resulting innovative design with modified fully conjugate tooth surface improves accuracy, backlash, and the life of the existing design.
