Claim 0:
1. An apparatus for oil lubrication of a rotationally fixed connection between two shafts, comprising:
the two shafts including a first shaft and a second shaft, with the first shaft engaging with a shaft region in a hollow-cylindrical shaft region of the second shaft, and the two shafts are operatively connected to each other in a form-fitting manner in an overlapping region,
wherein oil is introduced in an axial direction through a central opening into a first chamber in a hollow-cylindrical region of the second shaft, the first chamber being fluidically connected to a second chamber in the hollow-cylindrical region of the second shaft by a first fluidic connection,
wherein the second chamber is fluidically connectable to a third chamber by a second fluidic connection,
wherein the third chamber is arranged in the overlapping region between the first shaft and the second shaft, and
a sealing element, wherein the second fluidic connection between the second chamber and the third chamber is separated above a defined oil volume in the second chamber and above a rotational speed threshold of the two shafts via thea sealing element which is reversibly deformable at least in regions by the defined oil volume in the second chamber and a centrifugal force acting thereon and, in a deformed state, seals the second fluidic connection between the second chamber and the third chamber in relation to the second chamber.
