Abstract
An axial face seal has a sliding ring and/or a counter-ring for use with an elastic roll body. The ring has a seal leg having a sliding surface, and a supporting portion with a conical circumferential surface outside of the sliding surface for accommodating the elastic roll body. The seal leg also has an extended region that extends past the supporting portion. A reinforcement for the extended region is located between the extended region and the supporting portion.
Claims2
An axial face seal including a sealing ring;
- said sealing ring comprising:
- (a) an axially extending supporting leg having
- (1) an outer conical circumferential surface for supporting an annular elastic roll body thereon;
- (2) an inner circumferential surface defining, together with said outer conical circumferential surface, a thickness of said supporting leg;
- and
- (3) an axial end;
- (b) a radially extending sealing leg adjoining said supporting leg;
- said sealing leg having
- (1) a collar projecting radially beyond said inner circumferential surface of said supporting leg and away from said thickness;
- the radially projecting collar of said sealing leg having an outer circumference constituting an inner circumference of said sealing ring;
- and
- (2) an outer radial sliding surface being remote from said axial end of said supporting leg;
- and
- (c) a reinforcing rib provided on said projecting collar of said sealing leg and on said inner circumferential surface of said supporting leg;
- said reinforcing rib extending from said outer circumference of said projecting collar of said sealing leg to said axial end of said supporting leg.
