Patent number: 9869394Abstract: A sealing system for sealing shafts against liquid media, for example propeller shafts, impeller shafts, rudder stocks of ships and the like. Opposing corner regions of the sealing system that are located radially inside of a clamping space, for clamping at least one sealing ring, are formed by inclined run-on surfaces that diverge when viewed radially from the inside towards the outside. For accommodation in the clamping space, a clamping section of the sealing ring comprises two opposite edge regions that are formed by inclined surfaces that correspond to the run-on surfaces.Type: GrantFiled: December 5, 2014Date of Patent: January 16, 2018Assignees: SKF MARINE GMBH, SKF USA INC.Inventors: Ernst-Peter Von Bergen, Carlos Fangauf, Lars Ziemen, Dieter Von Borstel, Ivan Ristic, Guido Wuestenhagen

Patent number: 9447883Abstract: A seal for sealing around a shaft includes a radially outer clamp-in element to be clamped into a housing, an intermediate membrane part extending radially inwardly (toward the shaft) at an angle from the clamp-in element, and an angled base part at a radially inner end of the intermediate membrane part. A spring is received in a receiving groove that forms a spring pocket in the base part, and the spring exerts a contact pressure of a seal lip of the base part against the shaft. In a pressureless state without a pressure differential across the seal, the spring pocket has a width larger than the sectional diameter of the spring and thus forms a free play space for the spring in the pocket.Type: GrantFiled: February 29, 2012Date of Patent: September 20, 2016Assignee: Blohm + Voss Industries GmbHInventors: Ernst Peter Von Bergen, Lars Ziemen, Carlos Fangauf, Dieter Von Borstel, Guido Wuestenhagen, Ivan Ristic

Patent number: 8616840Abstract: A sealing arrangement is provided, including a sealing ring for sealing two machine elements from one another, the sealing ring being conFIGUREd in an installation space for the second machine element that is open toward the first machine element to be sealed, and sealingly contacting the surface to be sealed of the first machine element, by way of at least one dynamically loaded first sealing lip. The sealing ring is arranged under elastic axial and radial preloading within the installation space.Type: GrantFiled: May 27, 2008Date of Patent: December 31, 2013Assignee: Carl Freudenberg KGInventors: Ivan Ristic, Dieter Von Borstel

Publication number: 20130307222Abstract: In a seal (1) of shafts (7) relative to a medium, being received in housing-fixed support rings (4, 5), it is provided that in an embodiment of the seal with a clamp-in element (3) and an angled element with a seal lip (2) arranged via an intermediate part (6) whereby a contact pressure is applied via a spring (10). For this it is provided that the spring (10) is embodied in a receiving groove (11) as a spring pocket with a free space (12) for the spring in the pressureless state. A nose (13) as a retaining element for the inserted spring is arranged on the membrane as an intermediate part (6) above the spring pocket (11). The membrane is adjustable upon changing a tilt angle (?) by pressure loading up to reaching a limit pressure for contacting on an allocated housing wall (16) such as an extended support ring (5). Thereby an enlarged bottom side contact angle (?) is established in the angled region with the seal lip (2).Type: ApplicationFiled: February 29, 2012Publication date: November 21, 2013Applicant: BLOHM + VOSS INDUSTRIES GMBHInventors: Ernst Peter Von Bergen, Lars Ziemen, Carlos Fangauf, Dieter Von Borstel, Guido Wuestenhagen, Ivan Ristic

Publication number: 20080315527Abstract: A sealing arrangement is provided, including a sealing ring for sealing two machine elements from one another, the sealing ring being configured in an installation space for the second machine element that is open toward the first machine element to be sealed, and sealingly contacting the surface to be sealed of the first machine element, by way of at least one dynamically loaded first sealing lip. The sealing ring is arranged under elastic axial and radial preloading within the installation space.Type: ApplicationFiled: May 27, 2008Publication date: December 25, 2008Applicant: Carl Freudenberg KGInventors: Ivan Ristic, Dieter Von Borstel

Patent number: 7083170Abstract: A rod or piston primary seal, which includes a primary seal (2) facing the space (1) to be sealed and a secondary seal (3) facing away from it, in which the primary seal (2) is fitted into the groove (4), of a holding element (5), open in the direction of the relatively movable machine part (11) which is bounded, on the side facing away from the space (1) to be sealed, by a first side surface (7) which extends essentially at right angles to the sealing axis (6), and includes a sealing edge ring (8) made of tough, hard plastic which has a sealing edge (9) lying adjacent to the machine part (11) and is pressed with its sealing edge (9) onto the machine part (11) by a profile ring (10) made of elastomeric material which is supported on the bottom surface (12) of groove (4) and lies adjacent to sealing edge ring (8) with its inner surface (13), the sealing edge ring (8) having a profile bounded essentially by a right angle between the sealing edge (9) and the bounding surface (14) facing the first side surface (7Type: GrantFiled: April 4, 2002Date of Patent: August 1, 2006Assignee: Carl Freudenberg KGInventors: Dieter Von Borstel, Günter Reichow, Hans-Jürgen Timmermann
