Abstract
A PROGRAM was undertaken to evaluate the performance of cams and tappets as influenced by design, lubrication, and metallurgical techniques. Car and dynamometer tests and a newly developed bench test are described. The latter shows promise in lending itself to the determination of the effects of single variables in a practical, short, and economic fashion, while the former do not.
For the conditions of high contact stress and boundary lubrication experienced in cam and tappet operation, the authors draw several conclusions from the test work described, categorically related to the design, lubrication, and metallurigical problems present.
