JOURNAL BEARING AND METHOD OF FACILITATING HYDRODYNAMIC OIL FLOW, LOAD CAPACITY AND OPTIMIZATION OF BEARING PERFORMANCE

摘要

A journal bearing 11 for use in an epicyclical gearbox 10 including a journal pin 14, a journal bearing body 25 into which the journal pin 14 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 25 during a high pressure event, thereby permitting a free flow of a lubricating fluid there between the journal pin 14 and the journal bearing body 25 during the high pressure event. In an embodiment, the journal pin 14 is configured to mimic the shape of the journal bearing body 25 at least at a high pressure point exerted upon the journal bearing body 25 during a high pressure event. An epicyclical gearbox 10 including the journal bearing 11 and method of facilitating a hydrodynamic oil flow in the planet gear journal bearing.
