    摘要: A hub bearing and a seal device therefore are disclosed. In one example, the hub bearing seal device includes inner and outer rings, a ring-shaped seal, and a seal retaining ring. A metallic framework is provided inside the seal. The seal is fixed to the outer ring via the metallic framework and a seal lip edge is provided on the metallic framework of the seal. The seal lip edge is in contact with the seal retaining ring in interference fit. The seal is further provided with another layer of metallic framework having a different thermal expansion coefficient from that of the metallic framework. Together, the metallic frameworks form a bimetallic sheet type framework. During the operation of the seal device, the bimetallic sheet type framework can adjust the amount of interference between the seal lip edge and the seal retaining ring dynamically according to temperature change.

    摘要: Die Erfindung betrifft ein Radnabenlager und dessen Dichtungsvorrichtung. Die Dichtungsvorrichtung des Radnabenlagers umfasst einen Innenring (3) und einen Außenring (1) des Radnabenlagers, ein ringförmiges Dichtungsteil (2) und einen Dichtungsstoppring (4), wobei der Dichtungsstoppring (4) am Innenring (3) befestigt ist und der Außenumfang des Dichtungsteils (2) am Außenring (1) befestigt ist. Der Innenteil des Dichtungsteils (2) weist einen Metallrahmen (23) auf, das Dichtungsteil (2) ist über den Metallrahmen (23) am Außenring befestigt und gleichzeitig ist am Dichtungsteil (2) am Metallrahmen (23) eine Dichtungslippenkante (21) angeordnet, wobei die Dichtungslippenkante (21) mit dem Dichtungsstoppring (4) intervenierend in Kontakt steht.
    Erfindungsgemäß weist der Innenteil des Dichtungsteils (2) eine weitere Metallrahmenschicht (24) auf, die in Radialrichtung an der Innenseite des Metallrahmens (23) angeordnet ist, einen anderen Wärmeausdehnungskoeffizient aufweist als der Metallrahmen (23) und mit dem Metallrahmen (23) einen doppellagigen Metallrahmen (23, 24) bildet. Im Betrieb der Dichtungsvorrichtung kann der doppellagige Metallrahmen (23, 24) bei Temperaturveränderungen dynamisch die Stärke der Überlagerung zwischen der Dichtungslippenkante (22) und dem Dichtungsstoppring (4) regulieren.

    摘要: The invention relates to a centrifuge, comprising a vertically arranged shaft (2), which extends from the bottom through a bearing housing (3) for allowing a centrifugal drum (1) to rotate, and a bearing for the shaft, which is arranged on the bearing housing. The bearing has an upper and a lower bearing unit (4, 5) which are disposed at a distance from one another. An annular space (7) filled with a protective gas is provided between the upper and lower bearing unit and between bearing housing and shaft. Furthermore, the bearing housing (3), which is designed as a double jacket, comprises an annular space (8) filled with a coolant adjacent to the annular space (7) filled with protective gas. As a result, it is possible to provide a temperature-controlled bearing having a particularly low temperature load.
