Rotating machine part, in particular a rotor of a cycloid ship's propeller

Abstract

The invention relates to a rotating machine part having, in particular, a flat housing or base with an essentially cylindrical outer wall or with symmetrically distributed projections which are arranged in particular in the form of a star, in particular a rotor (1) of a cycloid propeller, the cylinder axis or rotor axis being the same as the rotation axis and the machine part or housing rotating in an atmosphere or a medium which is able to transmit heat to a sufficient extent to produce a required cooling effect on the machine part or housing or in its interior. The invention is distinguished by the fact that a central introduction point is provided on the machine part or housing as well as return lines (12) for a further heat transmission medium, which return lines (12) each have an inlet for the heat transmission medium which is to be returned, which inlet is arranged in the radially outer region of the machine part or housing, and by the fact that the return point for the heat transmission medium which is to be returned is provided in the vicinity of the central axis or the central region (24) of the machine part or housing.
