| Abstract: | The kinematic analysis of a planar cam mechanism can be realized by applying substitute equivalent linkage instead of higher pair.The planar cam mechanisms with a roller translating follower are discussed.After finding the picth curve according to the cam contour,the planar cam mechanism with a roller translating follower are transformed into a planar mechanism with a knife-edge translating follower.Then the planar mechanism with a knife-edge translating follower is transformed into a linkage mechanism by applying substitute equivalent linkage instead of higher pair.After that the kinematic analysis is made and a demonstrating example is given. |
