ABSTRACT:
A bearing is located in a bore formed in a casing for rotatably supporting a shaft extending inside the casing and a shaft seal is located between the shaft and the bearing bore and spaced from the bearing in a longitudinal direction of the shaft. An oil chamber is defined by the shaft seal and the bearing. An oil feed hole is formed in the casing for directly feeding an oil into the oil chamber from an oil source. The oil is then directed to the bearing from the oil chamber. A partition plate is placed in the oil chamber to form a gap between the shaft and itself (partition plate) for allowing part of the oil to flow to the bearing from the oil chamber through the gap and allowing the remainder of the oil to be dammned by the partition plate to form an oil pool in which the shall seal is always immersed.
