Overrunning clutch of 3d measurement simulation and structure design With the rapid development of mechanical engineering industry, various types of machinery for overrunning clutch requirement also enhanced gradually, higher load, the more stable transmission has gradually become the development trend of overrunning The graduation design mainly USES the reverse engineering thinking, and mechanical or related courses are acquisition of knowledge as the basis, using three-dimensional copy several machine test tools and means for the existing overrunning clutch measuring This paper introduces the use of 3d copy number Imageware measured wedge of machine design analysis and fitting, according to the fitting results using SolidWorks software for 3d modeling and make 2d drawings of SolidWorks software is built, the 3d model for dynamic simulation and analysis, finally get its 3d model and design drawings, and the dynamic simulation of overrunning clutch process and !
