1. A cooling oil guiding device for rotating component parts, comprising:
an oil channel that extends in radial direction, wherein cooling oil can be supplied from radially inward and the oil channel is partially open radially outwardly;
outlet elements arranged in the oil channel;
blocking elements that are arranged entirely radially inwardly of the outlet elements in a radially outer area of the oil channel and configured to redirect the cooling oil exiting the outlet elements,
wherein the outlet elements and the blocking elements do not circumferentially overlap;
at least two passages in radial direction which are distributed along a circumference of the blocking elements; and
outlet channels, which are aligned with the at least two passages and inlets which are disposed between the outlet channels in circumferential direction are formed by the outlet elements, and an annular channel is provided between the blocking elements and the outlet elements to connect the inlets with the outlet channels and at least two passages, respectively,
wherein a cross section of each of the at least two passages decreases radially outward in radial direction.
