ABSTRACT:
The production of a bearing surface by coating a known bearing material directly on the surface of a gear bore. A process of coating bearing materials directly onto the surface of a gear and the product thereof. The surface is preferably the inner bore surface of a planet gear. The coating methods include sputtering and vapor deposition. The bearing material applied as a coating is preferably a copper-lead composition. The resultant gear having a bearing coating can be useful in any high density, high efficiency epicyclic gear train for aircraft, marine or land based power transmissions.
