Computerized Cam Analysis

MODEL NO – DOM-003

DESCRIPTION

The “LabTek” experimental 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.

A transparent protective cover ensures safe operation. The experimental unit is intended for demonstration in engineering education. It is not suitable to be used as a test bench in the field of endurance testing/tribology.
