Patent number: 9103446Abstract: A fluid seal assembly is disposable between an outer surface, i.e. engine block or any other part that requires application of the assembly and a rotatable member, such as, for example a shaft, wherein the assembly circumscribes the shaft and lubricates the shaft and the same rotates around the axis. The assembly includes at least three members: a casing unit, a sealing ring unit, and a liner. The assembly eliminates problems associated with prior art designs such as static leakage of oil, and clogging up the spirals with carbonized oil that negatively impact lifecycle of the fluid seals.Type: GrantFiled: September 15, 2010Date of Patent: August 11, 2015Assignee: AKTIEBOLAGET SKFInventor: Linas L.

Patent number: 8820751Abstract: A heavy duty composite oil seal with an outer cup and a plastic inner cup. The outer cup includes a major diameter mounting flange portion terminating in a curl, a minor diameter wear sleeve portion, and a transition portion joining the major and minor diameter portions. There is an elastomeric seal body and an embedded stiffener, with the elastomeric seal body having a sealing lip contacting the inner axial surface of the wear sleeve portion. There is a plastic inner cup member with an axial flange substantially co-extensive with the mounting flange and entrapped along the major diameter flange portion between the curl portion and the transition portion of the outer cup. The inner cup also has a radially extending flange that engages a radial portion of the elastomeric seal body. The plastic inner cup member has a continuous curvilinear inner surface.Type: GrantFiled: June 11, 2012Date of Patent: September 2, 2014Assignee: Aktiebolaget SKFInventors: Dennis N. Denton, Linas L.

Patent number: 8734022Abstract: A sealing device is provided for sealing a space between a hub and a spindle pivotally connected by a bearing, the hub being coaxially mounted on the spindle and extending in an axial direction and the bearing having an inner ring. The sealing device includes a radial shaft seal including a shell portion having an outer static sealing surface disposeable against the hub and a hinge portion having a radial sealing lip. A sleeve member includes an inner static sealing surface disposeable against the spindle, a running surface contactable by the sealing lip and a sleeve portion. The sleeve portion extends in the axial direction beyond a side surface of the bearing inner ring and is disposeable about a shoulder diameter of the bearing inner ring.Type: GrantFiled: April 21, 2010Date of Patent: May 27, 2014Assignee: Aktiebolaget SKFInventors: Rico Dittmar, Thilo Beck, Bernd Stephan, Arno Stubenrauch, Peter Volpert, Thomas Will, John M. Dominguez, Linas L. Maskaliunas

Patent number: 8534674Abstract: A unitized radial fluid seal includes a shell having a first elastomeric seal body affixed thereto and defining a primary seal lip. A sleeve includes a substantially cylindrical, axially-extending sealing flange and a protective flange extending substantially radially from the axially-extending sealing flange. A spring radially urges the primary seal lip into sealing contact with a sealing surface of the axially-extending sealing flange. A second elastomeric seal body is affixed to the sleeve and includes a resiliently-elastic angled lip extending from a terminal end of the axially-extending sealing flange opposite of the radially-extending protective flange. The sealing surface and an axially-outward facing surface of the angled lip define an angle (?) that is between about 130-170°. The primary seal lip is axially retained between the angled lip and the radially-extending protective flange.Type: GrantFiled: November 22, 2010Date of Patent: September 17, 2013Assignee: Aktiebolaget SKFInventors: Linas L. Maskaliunas, Bret Thomas Dana

Publication number: 20130001890Abstract: A heavy duty composite oil seal with an outer cup and a plastic inner cup. The outer cup includes a major diameter mounting flange portion terminating in a curl, a minor diameter wear sleeve portion, and a transition portion joining the major and minor diameter portions. There is an elastomeric seal body and an embedded stiffener, with the elastomeric seal body having a sealing lip contacting the inner axial surface of the wear sleeve portion. There is a plastic inner cup member with an axial flange substantially co-extensive with the mounting flange and entrapped along the major diameter flange portion between the curl portion and the transition portion of the outer cup. The inner cup also has a radially extending flange that engages a radial portion of the elastomeric seal body. The plastic inner cup member has a continuous curvilinear inner surface.Type: ApplicationFiled: June 11, 2012Publication date: January 3, 2013Inventors: Dennis N. Denton, Linas L.

Patent number: 7950670Abstract: A seal assembly having a seal bumper wall with a series of pyramid shaped formations lying on the bumper wall. The formations cause their apex portion to wear down rapidly in use, while the remainder of the pyramids remain and act as slingers and/or produce a convection effect to reduce temperature along the sealed area. In another embodiment, there are two each pyramid shaped formations located on each of several thrust bumpers, which are held in position by a retainer.Type: GrantFiled: September 28, 2009Date of Patent: May 31, 2011Assignee: SKF USA, Inc.Inventor: Linas L.
