Abstract
A lubrication system including a bearing compartment housing defining a bearing compartment housing interior having a bearing compartment housing interior surface and a bearing compartment housing exterior having a bearing compartment housing exterior surface; a shaft supported by bearings located within the bearing compartment housing; and a lubricant trap formed on the bearing compartment housing interior surface, the lubricant trap configured to contain at least one lubricant, the at least one lubricant configured to be released onto the bearing.
Claims13
A lubrication system comprising:
- a bearing compartment housing defining a bearing compartment housing interior having a bearing compartment housing interior surface and a bearing compartment housing exterior having a bearing compartment housing exterior surface;
- a shaft supported by bearings located within the bearing compartment housing;
- a first lubricant trap formed on the bearing compartment housing interior surface, the first lubricant trap located at a first axial distance from the bearings, the lubricant trap configured to contain a first lubricant, the first lubricant configured to release onto the bearings from the first lubricant trap responsive to a first temperature;
- and
- a second lubricant trap formed on the bearing compartment housing interior surface a second axial distance from the bearings, a second lubricant within the second lubricant trap, wherein the second lubricant is configured to release onto the bearings from the second lubricant trap responsive to a second temperature.
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 defining a bearing compartment housing interior having a bearing compartment housing interior surface and a bearing compartment housing exterior having a bearing compartment housing exterior surface;
- the shaft supported by bearings located within the bearing compartment housing;
- a first lubricant trap formed on the bearing compartment housing interior surface, the first lubricant trap located at a first axial distance from the bearings, the lubricant trap configured to contain a first lubricant, the first lubricant configured to release onto the bearings from the first lubricant trap responsive to a first temperature;
- and
- a second lubricant trap formed on the bearing compartment housing interior surface a second axial distance from the bearings, a second lubricant within the second lubricant trap, wherein the second lubricant is configured to release onto the bearings from the second lubricant trap responsive to a second temperature.
