The task of the starter motors is to rotate the combustion engines to the necessary rotational speed. An element of the mechanism is a free running clutch. It has two functions. The first one is the torque transmission from the driving member to the driven shaft, and to speed up the combustion engine. The other function is to disconnect the elements, when the combustion engine has been already turned over, and the driven shaft rotates faster than the driver. In this paper the pressure angle as the most important parameter of operation is investigated. A new curve is developed for inner profile of housing, which operates to constant wedge angle.
