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,we thought over all the requests in the round and design the rational structure cycloid-gear reducer.

  In this design,we built the exact 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.

  With the software MATLAB,we use the cycloid-gear reducer for optimization design research.By practical calculation and results analysis,we prove that the establishment of optimization design mathematical model can be a true reflection of the design issues.At the same time,it provides an important foundation for further research.
