Description

This unit is used to study the phenomenon of CAM Mechanisms. A motor is mounted on a rigid base and a CAM shaft is getting the motion from the motor through a coupling. The CAM consists of 4 interchangeable CAM plates and 2 different tracers, a mass and spring are used to simulate the value a plotter allows the actual lift curve and stroboscope (optional) can be used to view the movement process and lift.

A mass and a spring are used to simulate the valve. In order to demonstrate the so-called “valve wobble”, the spring rate, mass and speed are adjustable within broad limits. A plotter allows the actual lift curves to be recorded. The open design allows the observation of every detail of the movement process. A stroboscope (Optional) can be used to provide a particularly impressive view of the movement process and lift.

The experimental unit is intended for demonstration purposes in technical education.
