Abstract
A journal bearing for use in an epicyclical gearbox including a journal pin, a journal bearing body into which the journal pin is disposed and at least one lubricating fluid inlet. The lubricating fluid inlet is configured to provide for an input of a lubricating fluid in a loaded arc portion proximate at least one high pressure point exerted upon the journal bearing body during a high pressure event, thereby permitting a free flow of a lubricating fluid there between the journal pin and the journal bearing body during the high pressure event. In an embodiment, the journal pin is configured to mimic the shape of the journal bearing body at least at a high pressure point exerted upon the journal bearing body during a high pressure event. An epicyclical gearbox including the journal bearing and method of facilitating a hydrodynamic oil flow in the planet gear journal bearing.
