摘要:
A crankshaft has spaced-apart cheeks and a cylindrical surface between the cheeks. A split ring bearing assembly has first and second bearing parts that join to encircle the cylindrical surface. First and second split ring seal assemblies each have first and second seal parts that join to encircle and sealingly contact with the cylindrical surface on each side of the split ring bearing assembly. A journal includes a first and second journal halves having cylindrical recesses receiving the crankshaft so that the split ring bearing assembly bears upon the journal and the first and second split ring seal assemblies sealingly contact with the journal halves. A lube fill fitting is provided in the journal for the introduction of lubricant which is permanently sequestered between the first and second split ring seal assemblies to provide sealed lubrication of the split ring bearing assemblies.
