Abstract
A power transmission system includes a shaft, a stator disposed within the shaft and substantially concentric with the shaft; and at least one supporting element positioned between the stator and the shaft and configured to support the shaft on the stator to reduce a vibration of the shaft and allow the shaft to rotate relative to the stator. A gas turbine engine including the power transmission system is also described.
Claims19
A power transmission system, comprising:
- a shaft;
- a stator disposed within the shaft and substantially concentric with the shaft;
- at least one internal bearing positioned between the stator and the shaft to support the stator within the shaft, wherein said internal bearing is rotatable along with the shaft, relative to the stator;
- and
- at least one supporting element different from the internal bearing positioned between the stator and the shaft,
- wherein each of the stator and the shaft is in contact with the at least one supporting element or oil associated with the at least one supporting element, and
- wherein the at least one supporting element is configured to directly support the shaft on the stator or support the shaft on the stator via the oil associated with the at least one supporting element to reduce a vibration of the shaft and allow the shaft to rotate relative to the stator.

A gas turbine engine, comprising:
- a high-pressure compressor;
- a combustor;
- a high-pressure turbine;
- a high-pressure shaft connecting the high-pressure compressor and the high-pressure turbine;
- a low-pressure shaft connecting a low-pressure turbine to either a fan rotor or a power equipment;
- a stator disposed within the low-pressure shaft and substantially concentric with the low-pressure shaft;
- at least one internal bearing positioned between the stator and the low-pressure shaft to support the stator within the low-pressure shaft, wherein said internal bearing is rotatable along with the low-pressure shaft, relative to the stator;
- and
- at least one supporting element different from the internal bearing positioned between the stator and the low-pressure shaft,
- wherein each of the stator and the low-pressure shaft is in contact with the at least one supporting element or oil associated with the at least one supporting element, and
- wherein the at least one supporting element is configured to directly support the low-pressure shaft on the stator or support the low-pressure shaft on the stator via the oil associated with the at least one supporting element to reduce a vibration of the shaft and allow the low-pressure shaft to rotate relative to the stator.
