Design of New Involute Gear Fan Chengyi

Chen Zhihua，Liu Quan

Abstract:The old gear Fan Chengyi drawing gear tooth profile is not convenient，it can only draw some gear profile.The new model that can automatically draw the complete gear tooth profile of the device is designed.The utility model has the advantages and innovation is the clever use of the characteristics of gear mechanism.Based on the cam mechanism and screw mechanism，introduces the threedimensional modeling and application process and principle of these institutions are introduced.Accoding to the parameters of the Fan Chengyi，the gear parameters，the parameters of the gear shaft and the fit of the shaft are calculated and analyzed.The ADAMS simulation results of the gam mechanism show that the cutting tool are stable，reliable，and has good performance.
