Product Description

Description of Cam Analysis

Bench top apparatus to demonstrate the dynamic investigation of cam mechanisms, as used in motors for actuation of the valves. The Cam Analysis consists of 3 interchangeable cams and 2 different cam followers. The cams are rotated using a electronically controlled motor and pulley gear arrangement. A large inertia mass is connected between the motor and cam to ensure consistent running at various speeds.

The follower attaches to a vertically moving shaft which simulates the valve itself. On top of the shaft can be attached a number of removable masses which allow the valve mass to be changed.

Experimental Capabilities of Cam Analysis

 

  1. Comparison of the various cam designs
  2. Elevation curves supplied by unsuitable pick-ups
  3. Elevation curve for a bouncing pick-up
  4. Determination of the limiting speed and its comparison with the theoretical value
  5. Relationship between cam and spring force
