Cam Analysis Apparatus
Product Code : EL-TOML-11023
Quick answer: The cam analysis apparatus is used to study cam profiles and follower motion, plot displacement against cam angle and find the jump speed at which the follower leaves the cam. It includes eccentric, tangent and circular arc cams, mushroom, flat-faced and roller followers, a dial gauge and a variable speed drive. Lab Exports manufactures it in Delhi for engineering colleges, polytechnics and TVET institutes.

How the cam analysis experiment is done
A cam turns rotary motion into a set pattern of reciprocating motion in the follower, as in the valve gear of an engine. The shape of the cam decides the follower's displacement, velocity and acceleration over each revolution, while the follower type, mushroom, flat-faced or roller, changes the contact conditions and the wear.
At low speed the follower stays in contact with the cam. As speed rises, the inertia force during the deceleration part of the lift grows with the square of the speed, and at the jump speed it overcomes the force holding the follower down, so the follower leaves the cam surface. Finding this speed for each cam and follower pair shows why cam profile and follower mass matter in high-speed machines.
- Mount the chosen cam on the camshaft and fit a follower.
- Turn the cam by hand in equal angle steps and read the follower lift on the dial gauge.
- Plot follower displacement against cam angle to get the lift profile.
- Run the motor and raise the speed slowly until the follower is seen or heard to jump.
- Repeat for the other cams and followers and compare the profiles and jump speeds.

Frequently asked questions
What cam and follower types are supplied?
Eccentric, tangent and circular arc cams, with mushroom, flat-faced and roller followers, one of each.
What is jump speed in a cam experiment?
It is the speed at which the inertia of the follower overcomes the force keeping it on the cam, so the follower lifts off the cam surface.
