ABSTRACT:
A journal bearing is lubricated with a disk on the shaft which sweeps through oil in a sump for picking up oil and transporting it upwardly in the direction of rotation of the disk to above an oil inlet for a bearing where it is scraped off the disk and caused to flow into the bearing. After a segment of a disk emerges from the oil sump, the disk enters a shroud which has a channel-shaped cross-section and whose back wall at least is curved with a decreasing radius as it extends away from the sump toward the scraper. The shroud captures the oil which would otherwise be spun off of the disk at high speeds so the maximum quantity of oil is retained on the disk when it reaches the scraper. A new scraper design is also disclosed.
