School Lab Computerized Cam Analysis

School Lab Computerized Cam Analysis

The Computerized Cam Analysis unit allows the dynamic investigation of a cam mechanism at various speeds.  
Four typical cams with corresponding engaging members are compared in terms of their motion behavior.  
The valve is simulated with a mass and a spring.
A recorder synchronized with the cam member records the actual elevation curve of the cam mechanism.  
A speed-controlled drive motor with a large flywheel generates a speed as constant as possible.  
The open design means that the motion is clearly visible in every detail.
The experimental unit is intended for demonstration in engineering education.  
A transparent protective cover ensures safe operation.  
It is not suitable to be used as a test bench in the field of endurance testing/tribology.
