Abstract
　　　The cycloid—gear reducer is one of the most important transmission components of the pumping unit by its smaller volume，lighter weight and effective  transmission. In order to realize four targets which include high transmission efficiency, high reliability and the excellent dynamics performance and guarantee credible lubricate ability, receive high efficiency of transmission, and make it easy for manufacture, assembly and inspection, we thought over all the requests in the round and design the rational structure cycloid—gear reducer.
　　　In this design，we built the exact force analysis mathematical model of the cycloid—gear reducer, analyzed the forces born by the cycloid-gear, the bearings and the shaft, and produce the Matlab language software analyze of the forces analysis. We analyzed the forces of parts in the cycloid—gear reducer and calculated the intensity and the life of parts. From analyzed the results, we found the parts are our requests.
   When we establish the three—dimensional structure of the Planet—cycloid Reducer model with the software UG，Carry on visual design and virtual assemble and drawing paper．The result of study have the guide meaning to accelerate design speed and quantities of the Planet—cycloid Reducer．
