The paper “The Efficiency of Cam (Gear)? presents an original method which may 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. The consumed motor force, Fc, perpendicular in A on the vector rA, is divided in two components: a) Fm, which represents the useful force, or the motor force reduced to the follower; b) the sliding force between the two profiles of cam and follower , (see the picture 1). See the written relations (2.1-2.10). See this paper from one of these websites:
