ABSTRACT:
The invention relates to a rotor disk for the rotor of a non-positive displacement machine with at least one borehole extending in an axial direction. The aim of the invention is to provide a rotor disk for a non-positive displacement machine that has an increased serviceable life. To this end, the boring extends in an at least partially convex manner whereby having an enlarged diameter in the middle area in order to increase internal compressive stress an to reduce tangential stresses.
