Abstract：Aiming at the rapid design and modeling problems of jaw clutch，based on the development platform of SolidWorks 2010，aprogram was written with VB for the parametric design of the rectangular jaw clutch. The secondary development method with SolidWorksbased on VB language was detailed explained and the dimension parameter database of rectangle jaw clutch was set up. The method ofthe rectangular jaw clutch's parametric design was investigated by the way of DLL development. A graphical user interface was provided.With feature of program drivers，a rapid modeling way of rectangle jaw clutch can be realized，and an intelligent block with automatic

modeling with jaw clutch correlation parameters was established based on SolidWorks platform. The results indicate that this kind of module can quickly read structural parameters from a database or compute the structural parameters with the maximum transmissiontorque according to the needs of user. In this case the threedimensional solid model of jaw clutch can be export to the SolidWorks GUI.By means of such kind of block，the ability of rapid modeling for specific components with SolidWorks was strengthened，the workload forthe design of jaw clutch can be reduced，and the intelligent and automatic design ability for jaw clutch can be highly enhanced.
