Abstract
A lubrication system including a bearing compartment housing; a shaft supported by bearings located within the bearing compartment housing; and a flinger in operative communication with the shaft, the flinger configured to propel at least one of a lubricant, air and a mist of lubricant entrained in the air onto the bearing.
Claims18
A lubrication system comprising:
- a bearing compartment housing;
- a shaft supported by bearings located within the bearing compartment housing;
- and
- a flinger formed integral and monolithic with the shaft, the flinger configured to propel at least one of a lubricant, air and a mist of lubricant entrained in the air onto the bearing.

A lubrication system comprising:
- a gas turbine engine having a gas turbine engine housing, the gas turbine engine housing having a forward portion opposite an aft portion;
- a shaft mounted within the gas turbine engine housing, the shaft having an axis;
- a bearing compartment housing formed within the gas turbine engine housing;
- at least one bearing located within the bearing compartment housing supports the shaft;
- and
- at least one flinger formed integral and monolithic with the shaft, the at least one flinger configured to propel at least one of a lubricant, air and a mist of lubricant entrained in the air onto the at least one bearing.
3 more elements
A process for delivering a lubricant in a lubrication system comprising:
- mounting a shaft within a gas turbine engine housing of a gas turbine engine having a forward portion opposite an aft portion, the shaft having an axis extending from the forward portion to the aft portion;
- forming a bearing compartment housing within the gas turbine engine housing, the bearing compartment housing comprising an interior surface and an exterior surface, and the bearing compartment housing being configured to house at least one bearing configured to support the shaft;
- forming at least one flinger integral and monolithic with the shaft;
- and
- configuring the at least one flinger to propel at least one of a lubricant, air and a mist of lubricant entrained in the air onto the at least one bearing.
