Determining the Dynamic Efficiency of Cams

Abstract

The paper presents an original method to determine the efficiency of a mechanism with cam and follower. The originality of this method consists of eliminating the friction modulus. In this paper one analyzes four types of cam mechanisms: 1.The mechanism with rotary cam and plate translated follower; 2.The mechanism with rotary cam and translated follower with roll; 3.The mechanism with rotary cam and rocking-follower with roll; 4.The mechanism with rotary cam and plate rocking-follower. For every kind of cams and followers mechanism one uses a different method in determining the best efficiency design. One takes into account the cam’s mechanism (distribution mechanism), which is the second mechanism from the internal-combustion engines. The optimizing of this mechanism (the distribution mechanism), can improve the functionality of the engine and may increase the comfort of the vehicle too.
