Abstract
A device for testing an endless chain-link mechanism comprises a disc, mounted to a DC-servomotor, which is resiliently urged against the rollers which serve to support the chain-link. The current of the motor is recorded in function of time and the significant part which is a measure of the resistance to rotation is determined. When this value exceeds a predetermined one, the roller is considered to be defective. Auxiliary circuits for signal processing may be provided, if desired.
