Cam Analysis Apparatus

Cam Analysis Apparatus .

Desciption of Cam Analysis Apparatus

A vertical pillar contains the main spindle for each Cam Analysis Apparatus to be rotated, whilst a dial gauge has its anvil resting on the top edge of the cam. Each cam is mounted on a central shaft and is free to rotate about this shaft. The cams are rotated by hand.

The rise and fall displacement of the Cam Analysis Apparatus, as it rotates through 360°, is measured using a dial gauge. The angular position of the cam is shown on a protractor and a pointer, this assembly allows the cams position through rotation to be recorded. Cams and followers are easily changed and graphs for the variety of cams can be created to compare the linear change with the rise and fall of the follower.

Experimental Capabilities of Cam Analysis Apparatus

1. To determine a graph of follower displacement against angular rotation of the cam
2. To derive the velocity and acceleration diagrams, and determine the maximum acceleration of the follower
3. To assess the effect of different cams and followers
4. To compare experimental and calculated results
