Geometric parameters and wear resistance of cam profile of a gas distribution mechanism

The paper analyzes the components of cam profile a camshaft an internal combustion engine. authors developed method calculating width and area contact, as well degree slippage occurring in friction pair consisting tappet sleeve, resistance to wear profile, depending on roughness surfaces working lubricating medium. Studying parts shows that uneven occurs along its surface. values parameters affecting process are shown by choosing wearing environment surface cam. trends changes amount presented form table generalized case, final conclusions reached based calculation results.
