【Abstract】 Taking the design of commonly used outer geneva wheel of automatic machinery as an example,the mathematical model of parameterized design of geneva mechanism was established.Using the secondary development techniques of AutoCAD made by VB,the parameterized design and kinematics simulation on geneva mechanism were successfully realized.Under the circumstances of selecting the kinematical working situation and force bearing condition of geneva mechanism,this system could conduct automatic inspection on the designing result,and could realize automatic output of engineering drawing of the geneva mechanism and carry out the marking of dimensional parameters and technical requirements, thus enhanced the designing efficiency of geneva mechanism,and provided theoretical basis for the digitized design and machining of the geneva mechanism.更多还原
