Service Life of the Cam Mechanisms

Original language description

Rolling contact fatigue is very closely connected to the service life of the cam mechanisms. The most common manifestation is pitting. This defect occurs on the contact surface and seems like a pit. This type of crack can lead to bigger damage of the functional parts of the mechanism. We can use two methods for service life estimation. The first method is the theoretical estimation. Its advantage is that it is quick and relatively easy. One dis-advantage is that it can be very inaccurate and can be dependent on the input pa-rameters accuracy. In addition, different theories can give different results. The second possibility is to estimate the service life by an experimental meth-od. This method is based on the loading of the contact surfaces and observing the crack formations. We operate it on a special test rig. After this we can find de-pendence between the loading force and the number of cycles leading to the sur-face damage. This information can be completed with data describing properties of the tested material e.g. hardness, purity, hardening parameters etc. We can es-timate the service life of the real cam mechanism on basis of all this obtained in-formation. This paper deals primarily with the surface damage and its influence on the service life of the cam mechanisms. Attention is paid to both methods of service life estimation. The test rig developed in our company is described here.
