Abstract
The present disclosure provides an inexpensive self contained lubrication system for the bearing which rotatably mounts a turbine engine shaft to the support housing in a turbine engine. The lubrication system includes a first seal assembly which extends between the shaft and the housing at a position axially spaced from one side of the bearing assembly and a second seal assembly extending between the shaft and the housing at the position axially spaced from the other side of the bearing assembly. The bearing assemblies form a sump chamber in the support housing which contains a lubricant. Each bearing assembly includes a resilient O-ring extending between the shaft and the support housing while two impellers attached to the shaft within the sump chamber pump the lubricant in the sump chamber through the bearing assembly and back to the sump chamber during shaft rotation.
