SD-1.54 – Cam and Follower Apparatus

A vertical pillar contains the main spindle for each cam to be rotated, whilst a dial gauge has its anvil resting on the top edge of the cam.

Description

A vertical pillar contains the main spindle for each cam 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, as it rotates through 360°, is measured using the dial gauge.

The angular position of the cam is shown on a protractor and a pointer. 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. A set of cams are supplied as standard along with a set of followers which run on the perimeter of each cam. Each cam can be easily changed and the angular and dial gauge readings are clear.
