Speciális geometriájú gépelemek rekonstrukciója

Abstract

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 already turned over, and the driven shaft rotates faster than the driver. In this paper the fundamental knowledge is presented and a new method which helps us to determine the inner profile curve at the housing of the clutch. This method gives a chance to reconstruct roller freewheels having unknown geometry.
