Based on the study of arc tooth profile harmonic gear meshing principle
the design method of double arc harmonic gear drive rigidity wheel and flexible wheel basic tooth profile is proposed.Through threedimensional CAD design software SolidWorks to view the matching situation of flexible wheel and rigidity wheel
and by using finite element method
the displacement deformation of flexible wheel tooth profile is studied.The elastic deformation process of flexible wheel under wave generator is simulated and the rationality of flexible wheel tooth profile design is verified through the simulation.
