Problems solved by technology

[0018] At no-load, the cycloidal wheel meshes with the single tooth of the needle tooth. After the torque is applied, the meshing cycloidal wheel and the needle tooth produce elastic deformation. Considering the influence of elastic deformation on the tooth profile, the tooth profile of the cycloidal wheel will be concave, no longer It is the theoretical tooth profile, and the conjugate meshing relationship between the cycloid wheel and the pin teeth is destroyed, which affects the transmission characteristics of the RV reducer and reduces the transmission accuracy
