This paper presents a model of cosine gear planetary transmission with small number teeth difference (CG_PTSTD). Firstly, the mathematical model of the CG_PTSTD is established based on the theory of engagement, including the equations of the conjugate internal gear and the meshing line. Then an example of the CG_PTSTD is developed. In this example, the 2D and 3D models of the CG_PTSTD are established, and the bending and contact stresses are analyzed by finite element software ABAQUS. The results show that the cosine gear can be successfully applied to the PTSTD without tooth tip interference and there are multi teeth simultaneously participating in the mesh.
