摘要

PURPOSE: An oil return cover is installed in a rotation shaft of a centrifugal separator with a small gap to circulate oil, thereby cooling friction portion. CONSTITUTION: A bearing is installed in a housing cover having a rotation shaft of a centrifugal separator. A lubricating support is installed in one side of the bearing for cooling and lubricating of the bearing. An oil supply passage(6) is formed in the central portion of the rotation shaft. An oil leakage hole(7) is formed in outer circumference of the bearing to leak oil. An oil discharge groove is formed in lower part of the housing cover body. An oil return cover(11) is installed in corresponding position of the oil discharge groove.
