According to the deformation coordination conditions of the cycloid pinwheel, it can be seen from Figure 2 that when the cycloid gear teeth and the pin teeth mesh, f is the swing angle of the cycloid gear... angle of the i-th pin tooth relative to the rotating arm. Considering the modification factor, the contact load per unit length on the tooth width direction is as follows:  ......
