This paper presents an original method to determine the dynamic parameters at the camshaft (the distribution mechanisms). The authors introduce a new pressure angle, alpha, and a new method to determine the two pressure angles, alpha and delta, at the rotary cam and tappet with translational motion with roll, with a great precision. We determine initially the mass moment of inertia  (mechanical) of the mechanism, reduced to the element of rotation, ie at cam (basically using kinetic energy conservation). The rotary cam with translated follower with roll is synthesized geometric, kinematics and dynamic.
