摘要：
A new sprocket was developed by simulating actual meshing process of sprocket and rollers. Based on the theory of approximate conjugate meshing, a way of simulating the meshing process of roller chain drive was developed to realize the sprocket virtual machining. The profile of sprocket teeth was the envelope of rollers which moved on the sprocket rough. Virtual machining of sprocket profile was performed using secondary developing technology of AutoCAD. A dynamic model of a roller chain drive mechanism with new sprocket was built using multi-body dynamic techniques. The meshing process of roller chain drive can be accurately simulated by this model. Dynamic simulation results using mechanism with new sprocket are compared with those using mechanism with ISO 606 sprocket. Simulation analysis shows that tension between chain links is decreased and chain/sprocket meshing impact is also reduced by applying the new sprocket.
