ABSTRACT:
An improved sleeve bearing and associated lubrication system for the rotor shaft of a steam turbine. The bearing is lined with a metallic-polymeric composite, and is fixedly supported within a housing defining a reservoir containing a supply of liquid lubricant. The lubrication system includes a ring loosely surrounding the rotor shaft at a location spaced axially from the bearing. A lower portion of the ring is partially submerged in the lubricant. The ring is rotatably driven in response to rotation of the rotor shaft, with lubricant picked up on the ring being centrifugally discharged radially outwardly onto the surrounding housing walls. A system of communicating troughs, scuppers and passageways receives lubricant running off the housing walls for delivery under gravity to the bearing. Return passageways direct lubricant exiting from the bearing past water cooled chambers, over a weir and back to the reservoir.
