ABSTRACT:
Oil is supplied to bearing1and returned to oil storage chamber6avia chamber2aand pipe2b. First oil return chamber8and second oil return chamber7communicate via a hole, and second oil return chamber7communicates with oil supply chamber6via oil return hole9. The opening of the extension pipe10of oil return hole9has a small gap, to result in negative pressure in extension pipe10. The negative pressure sucks the oil leaking from between bearing cover3and rotor shaft20. The oil leaking is suppressed, keeping the supply of the lubricating oil to the bearing excellent.
