Patent number: 8523186Abstract: A slide ring seal arrangement comprises a rotationally fixed slide ring (4) and a slide ring (11), which is provided for rotating together with a rotating component, these slide rings each being held in a loose seat and interacting, in, in essence, radially oriented sealing surfaces, which are prestressed with a main prestressing force while in contact with one another. Each slide ring, on its front face that faces away from the sealing surface, is axially supported on a supporting part (14, 17) via an annular bearing surface (16, 20) provided between the respective supporting part and the adjacent front face of the respective slide ring. A load ratio (d12?dH2)/(d12?d22) of =2.0, preferably between 0.8 and 2.0, preferably no greater than between 1.0 and 1.5, more preferably approximately 1.3 is maintained on the bearing surface (16, 20). The measurement (d1?d2) of each bearing surface (16, 20) is equal to =10 mm, preferably between 0.2 and 2.0, preferably no more than approximately 0.6 mm.Type: GrantFiled: July 6, 2006Date of Patent: September 3, 2013Assignee: EagleBurgmann Germany GmbH & Co.

Patent number: 7862046Abstract: A mechanical seal assembly including at least one pair of co-operating seal rings, one of which is provided for common rotation with a rotating component and the other of which is provided rotationally fixed at a stationary component. One of the seal rings is axially movable and axially biased with a biasing force against the other seal ring, the biasing force being transmittable through a force transmitting ring to the respective seal ring, in order to bias facing sliding surfaces of the seal rings, between which a sealing gap is formed during operation, in a mutual sealing engagement, and a secondary sealing assembly provided at the force transmitting ring for sealing the axially movable seal ring with respect to at least one circumferential guiding surface of a guiding component guiding the movement of the seal ring and the force transmitting ring.Type: GrantFiled: November 17, 2008Date of Patent: January 4, 2011Assignee: EagleBurgmann Germany GmbH & Co.
