System for the Contactless Sealing of a Rotatably Mounted Shaft with Respect to a Housing, and Gear Unit |
摘要 |
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. |

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 bores for conveying the lubricating oil from a centrifugal chamber to a collection chamber, the bores opening through into the centrifugal chamber, and opening through into the collection chamber; and 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 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 is collectable and feedable through the bore to the gap region. |
