Abstract
An improved film damper oil delivery pathway from an oil reservoir to a thin film fluidic damper is provided. An oil supply tube may be configured to mate to a bearing outer race. The bearing outer race may comprise internal oil flow circuit(s) configured to supply oil from the oil tube to the thin film damper for improved bearing compartment designs.
Claims20
A method of providing oil to a thin film damper comprising:
- coupling a portion of the thin film damper to an oil supply via an internal oil flow circuit, wherein the internal oil flow circuit is at least partially formed internal to a bearing outer race, wherein the internal oil flow circuit comprises a bossed port configured to mate with the oil supply tube, wherein the bossed port and the bearing outer race are formed as an integral part.
A bearing assembly comprising:
- a thin film damper positioned at least partially between a bearing housing and a bearing outer race, wherein oil is supplied to the thin film damper via an internal oil flow circuit, wherein the internal oil flow circuit is integral to the bearing outer race, wherein the internal oil flow circuit comprises a bossed port configured to mate with the oil supply tube, wherein the bossed port and the bearing outer race are formed as an integral part.
