SUPPORT JOURNAL BEARING OF TRACTION ENGINE OF RAILWAY LOCOMOTIVE (VERSIONS), METHOD FOR ENLARGING SURFACE AREA OF LUBRICATED CONTACT SURFACE OF SUCH JOURNAL BEARING, AND LUBRICATING WICK FOR BEING USED IN SUCH JOURNAL BEARING Russian patent published in 2012 - IPC F16C17/02 F16C33/04 F16C33/10 

FIELD: engines and pumps.

SUBSTANCE: support journal bearing (90) includes central lubricating wick and recirculation system consisting at least of two auxiliary lubricating wicks (92) located in the main seat of bearing near "6:00" clockwise position, or from oil drain and supply grooves interconnected with grooves of flinger (98), which serve for oil collection and provide additional lubrication for enlarging the area of that zone of the casing supporting the axle neck of bogie in longitudinal direction, which is wetted with oil. Method for enlarging the surface area of lubricated contact surface of the above journal bearing consists in the fact that inner parts of external and internal end surface of inner bearing sleeve are lubricated; at that, auxiliary outer and auxiliary inner wicks (92) are used respectively. At that, the corresponding wick (92) is installed in mounting pocket (36') made in the main bearing seat so that upper surface of the main wick (92) housing protrudes beyond the limits of the appropriate pocket (36') so that it can come into contact with some part of bogie axle surface, and at least some part of end surfaces of the corresponding wick (92) is separated from end walls of the corresponding pocket (36').

EFFECT: creation of journal bearing that provides additional lubrication of the surface in bogie axle channel in comparison to the volume which is provided with common central lubricating wick used at the present time.
