Abstract
A system for the contactless sealing of a rotatably mounted shaft with respect to a housing, and a gear unit, oil being provided in the interior of the housing, in particular, the rotating shaft protruding from the interior into the outer area; a centrifugal disk, joined in rotatably fixed manner to the shaft, having at least partially radially extending bores that connect oil from a centrifugal chamber to a collection chamber surrounding the centrifugal disk.

A system for contactless sealing of a rotatably mounted shaft with respect to a housing, comprising:
- housing flange part including a collection chamber, a centrifugal chamber, and a bore connecting the centrifugal chamber and the collection chamber, a first end area of the bore opening into the centrifugal chamber and a second end area of the bore opening into the collection chamber;
- and
- a gap region formed between a centrifugal disk, joined in rotatably fixed manner to the shaft, and the housing flange part, the gap region connecting the centrifugal chamber to the collection chamber, so that lubricating oil centrifuged off of the shaft into the centrifugal chamber is collectable and feedable through the bore into the gap region due to rotational movement of the shaft relative to the housing.
