Abstract: The effect and importance of the drive sprocket in the first convey of cantilever excavator are briefly introduced. Combing with the questions in the process of manufacturing, the Solidworks three-dimensional design analysis software is adopted to analyze the state and stress distribution situation of tooth profile and the meshing process of drive sprocket. Therefore, the new modeling and manufacturing scheme is proposed, and good application effect is obtained.

Key words: SolidWorks, Drive sprocket, Modeling and manufacturing scheme
