Graphic Method Design of Disk Cam Profile//YU Min
Abstract The cam mechanism can change the simple continuous motion of the cam to the complex motion of the follower according to the work requirement. The motion law of the follower depends on the profile of the cam. According to the cam profile designed by the actual requirements of the follower motion law, it is possible to achieve the expected requirements of engineering.

凸輪機構由凸輪、從動件和機架組成,結構簡單、緊湊,能夠把凸輪的簡單連續運動轉變為從動件的連續或不連續的任意預期運動。凸輪是主動件,從動件的運動規律由凸輪輪廓決定。凸輪輪廓的設計是以選定的從動件運動規律為依據的。endprint
