This unit is used to study the phenomenon of CAM Mechanisms. A CAM shaft receives motion from a motor using a coupling that is installed on a rigid base. A mass and spring are used to simulate the value, a plotter permits the actual lift curve, and a stroboscope (optional) can be used to view the movement process and lift. The CAM is made up of 4 interchangeable CAM plates and 2 different tracers.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. The real lift curves can be recorded using a plotter. The open layout makes it possible to see every aspect of the movement process. To get a particularly stunning view of the movement and lift, a stroboscope (Optional) can be used. The experimental unit is designed to serve as a technical education demonstration instrument.
