What is jump phenomenon in cam?

a. Follower looses contact with cam surface when cam rotates beyond particular speed due to inertia forces. b. Follower looses contact with cam surface when follower rotates beyond particular speed due to gravitational force. c. read more

We cannot expect the cam to move downward in an acceleration greater than “g”. It makes the follower to lose contact with the cam. This is called as jump phenomenon. read more

The jump phenomena cam be avoided by limiting speed of the cam. which results in system vibrations. The spring force is period of negative acceleration. the constraint and control of follower motion are not maintained. highly flexible cam and follower system with jump. During follower jump. This phenomenon is known as jump phenomena. read more
