SEALING ELEMENT

摘要

A sealing element for sealing a cylindrical inner surface of a first machine component and a cylindrical outer surface of a second machine component includes an inner ring, an outer ring arranged coaxially with respect to the inner ring, and a sealing gap, which is formed by an exterior lateral face of the inner ring and an interior lateral face of the outer ring. In an axial section through the common axis of the inner ring and the outer ring the sealing gap has a profile having an inlet section as a first end portion of the sealing gap having a first radius to the common axis; an outlet section as a second end portion of the sealing gap having a second radius to the common axis, wherein the second radius is smaller than the first radius; and a meander section, which adjoins the inlet section and which has a monotonically decreasing radius.

主权项

1. A sealing element (1) for sealing a cylindrical internal face (13) of a first machine component and a cylindrical external face (8) of a second machine component, having an inner ring (2), an outer ring (3) which is disposed coaxially with the inner ring (2), and a sealing gap (14) which is formed by an outer shell (7) of the inner ring (2) and an inner shell (12) of the outer ring (3), wherein the sealing gap (14) in an axial section through the common axis (A1) of the inner ring (2) and of the outer ring (3) has a profile with the following profile portions:
an entry portion (15) as a first end portion of the sealing gap (14), having a first radius to the common axis; an exit portion (20) as a second end portion of the sealing gap (14), having a second radius to the common axis (A1), wherein the second radius is smaller than the first radius; and a meandering portion (16) which adjoins the entry portion (15) and which has a monotonously decreasing radius.
