Roller chain drives are recognized to be one of the most effective forms of power transmission in mechanical systems. However the mesh between chain and sprocket is generally not a conjugate action. The noise and vibration in such systems can be a problem in the further development and application of this kind of mechanism. Based on the theory of approximately conjugate meshing, a way of simulating the meshing process of roller chain drive was developed to realize sprocket virtual machining. The principle of sprocket virtual machining and envelope molding is regarding the roller as cutter to machine sprocket rough. The profiles of sprocket teeth are the envelope of cutter when it moves on the rough. Virtual machining and design process of sprocket profile was investigated using secondary developing technology of AutoCAD. The dynamic model of roller chain drive mechanism with new sprocket was built by using multi-body dynamic techniques. The meshing process of roller chain drive can be accurately simulated by this model. Simulation analysis shows that the tension between chain links is decreased and the chain/sprocket meshing impact is reduced by applying new sprocket.
