초록

Contact pressure occurs whenever two surfaces contact between cam and roller. Especially excessive pressure peaks occur at the ends of the contact region. Such as scuffing or pitting will be induced when these operating conditions continuously occur on the surface. Camber effect is given to reduce damage by changing the shape of roller. The objective of this paper is to calculate contact pressure distribution by using a contact analysis considering camber and tilting angle. These results predict that camber effect of all machine components have influence on contact pressure distribution.
