The article deals with the process of torque camshaft at a constant speed. The method of release was determined by the normal force acting between the cam and the tappet. Subsequently, was expressed torque. A prerequisite for the calculations are a constant friction coefficient between the components of the mechanism and constant speed of the camshaft. Cam used for the purposes of this study generated polynomial lifting dependence. Part of this work is the calculation methodology lifting addiction. Course of torque is the conclusion presented on the values of the corresponding measuring station, which is the result of previous work on the subject.

The work deals with the design of a test equipment designed for fatigue testing of the cutter bed. The disk cam drives the rocker, which is pressed against the cam surface by the coil spring. The test drum (buchar) copies the movement of the rocker to generate the exciting force that is loaded by the bed of the milling cutter. Based on unmatched data, the Wohler curve will be determined. This article deals only with parts of the design station. In particular, the design of the cam will be discussed here.
