Abstract:
1. A system for contactless sealing of a rotatably mounted shaft with respect to a housing, an interior of the housing being filled at least partially with lubricating oil, comprising: a centrifugal disk, joined in rotatably fixed manner to the shaft, having centrifugal bores extending at least partially in a radial direction, so that the lubricating oil is conveyable from a centrifugal chamber to a collection chamber at least partially surrounding the centrifugal disk, the centrifugal bores opening through with a radially inner end area into the centrifugal chamber, and opening through with a radially outer end area into the collection chamber, a gap region arranged between the centrifugal disk and a flange part of the housing, the gap region connecting the centrifugal chamber to the collection chamber, a bore on the housing and leading into the gap region, that with its other end area opens through into a further collection-chamber area, so that lubricating oil centrifuged off into the further collection-chamber area by a centrifugal edge joined in rotatably fixed fashion to the shaft is collectable and feedable through the bore to the gap region; and a gap region connecting the further collection-chamber area to the centrifugal chamber.
