Design of journal bearings
Journal bearings must provide a balanced bearing geometry and adequate journal strength and must maximize the thickness of the high-pressure lubricating film developed during hydrodynamic lubrication. The thickness of lubricating films is affected by:
-Surface areas
-Journal and cone diameters
-Clearances between journal and cone
Manufacturing tolerances must be precise so that surfaces run true.
Roundness of journal and cone surfaces is important, and if any
part of a bearing is out of round, the effectiveness of the
lubrication regime will be adversely affected.
