Question

A flat-faced radial follower is driven through a total displacement of 38 mm. The follower moves upward 25 mm with constant acceleration for 120° and the remaining 13 mm with constant deceleration for 60° of cam rotation. The follower returns with simple harmonic motion in 90° and dwells for the remainder of the revolution of the cam. (a) For each type of motion, write an equation expressing S V AJ as a function cam angle 0 and draw S V A J diagrams (b) Calculate the minimum radius C and the maximum length of contact for each type of motion (c) Specify the minimum radius of the cam and the length of the follower face.
