Abstract

Abstract: The influences of torsion stiffness of harmonic gear drive considering crack were studied by use of fracture splits mechanics, the material mechanics and the system dynamics theories. The analytic calculation formulas of flexibility and stiffness coefficient on each member considering crack were deduced, the calculation methods of torsion stiffness were given and example enumerated. This method is simple and applicable to engineering calculation.
