英文摘要：

A technology of gear barrel finishing has been proposed, processing mechanism of this technology is elaborated, and complicated relative motion between the surface of the abrasive and the workpiece is mainly studied. A mathematical model is established, the formulation of calculating cutting speed is derived, and main factors that affect the processing effect are found theoretically. The influence law of the factors is analyzed by MATLAB. The surface roughness was obviously reduced after finishing. The surface roughness of gear that was shaven is Ra 0.7 m or so and could achieve Ra 0.265 m after finishing. Machining texture and surface micro cracks were disappeared. It can help to improve the life of gear and lower operating noise. The theoretical foundation for further study and production application was laid.
