ABSTRACT:
A bearing lubricating apparatus for a rotary machine has a rotary shaft rotatably supported by a rolling bearing, and an oil receiving portion which receives lubricating oil picked up by a pick-up member. The oil in the oil receiving portion is sucked by a suction nozzle and is sent to interior of the rotary shaft through a first passage. Then, the oil flows back through a second passage into the bearing. Oil supply nozzles are formed in the rotary shaft so that the oil is supplied to the bearing by a pumping action of the oil supply nozzles when the rotary shaft rotates.
