• Displacement curves for cam mechanisms:
    • arc/tangent/concave/asymmetric cam
    • Choice of roller tappet, cup tappet or trailing level


  • Action principle of cam mechanisms
  • 4 different cams: arc / tangent / concave / asymmetric cam
  • Roller tappet, cup tappet and trailing lever
  • Angled scale 0…360°, D=100mm
  • Dial gauge D=58mm
  • Cams and tappets easy to change, without use of tools

Cam mechanisms are used in many areas of technology, such as for valve control in combustion engines. The simple experimental set-up permits quick demonstration of the action principle, and can be used to demonstrate the influence of different cam shapes. The cam follower can work either as a roller tappet, cup tappet, or trailing lever. The stroke is measured using a mechanical position measurement gauge. A scaled disk indicates the associated angle of rotation.

The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments.
