摘要:
An auxiliary bearing system having a sleeve through which a shaft extends. A gap may be defined between the sleeve and the shaft when a primary bearing system supports the shaft, and the sleeve may engage and rotate with the shaft when the primary bearing system does not support the shaft. An oil ring may extend circumferentially around the sleeve and rotate in response to the rotating sleeve when the sleeve engages and rotates with the shaft. The rotating oil ring may distribute lubricant within the auxiliary bearing system.

A shaft lubrication apparatus 10 is provided and includes a rotatable shaft 11, a lubrication sump 12 and a lubrication ring 13. The lubrication ring 13 is rotatable with the rotatable shaft 11 with respect to the lubrication sump 12 whereby lubrication is transported from the lubrication sump 12 to the rotatable shaft 11.

A lubricant circulation system and method are provided for circulating lubricant used to lubricate the interface between a rotating member and a stationary member. Lubricant is drawn from a lubricant source and delivered to the stationary member. The system and method utilize the pressure generated by rotation of the rotating member in the stationary member to drive the lubricant through the stationary member and back to the lubricant source.

Bei einem Gleitlager für horizontale Wellen mit Ringschmierung weist der zur Aufnahme des Schmierringes (3) dienende radiale Schlitz (2) einen Bereich (5) seiner Seitenwand (6) auf, der in gleicher Weise wie die Bohrung (4) mit Lagermetall (7) versehen ist. Außerdem ist ein zurückgesetzter Absatz (11) in der Seitenwand (6) des radialen Schlitzes (2) vorgesehen, der sich parallel zur waagerechten Durchmesserebene (12) der Welle erstreckt. Die obere Begrenzungsfläche (13) des zurückgesetzten Absatzes (11) schneidet den Bereich (5) des Lagermetalls (7) in der Seitenwand (6) des Schlitzes (2) angenähert dort, wo der Schmierring (3) unter Berücksichtigung seiner möglichen Pendelung diesen Bereich (5) verläßt.
摘要:
A lubrication system for moveable machine parts within a housing have a sump containing a fluid and a rotatable shaft comprising a ring (16) eccentrically encircling and being frictionally rotated by shaft (14), ring being at least partially immersed in sump fluid to carry fluid during rotation for machine parts, a plurality of fluid carrying fins (24, 26) attached to ring (16) to increase the fluid carrying capacity of ring, fins commencing from each outer edge and extending partially inwardly along the ring with towards each other thereby forming an annular space (29) between fins and ring, conduit means (30) having an inlet located within annular space for receiving fluid carried in annular space and delivering fluid to moveable machine parts, and first and second abutments (18, 20) attached to shaft, one on each side of ring and spaced from ring sufficiently to form an axial gap for a fluid film which transmits rotational power from abutments to ring.
