<P>PROBLEM TO BE SOLVED: To timely feed oil between a rotating shaft and rolling bearings supporting the rotating shaft. <P>SOLUTION: This oil feeder for rolling bearings feeds oil to a plurality of rolling bearings 14a-14d for rotationally supporting on a body 12, the rotating shaft 10 having a plurality of a plurality of sections 22a-22d to be supported which periodically receive rotating reactions on portions of specific phases at different timing by the sections to be supported. The oil feeder includes an oil feed means which is attached to the body and has a discharge port 34b for lubricating oil formed at the slidable contact surface of the rotating shaft in slide-contact with a predetermined portion and oil feed passages 30a, 30b which are formed in the rotating shaft and the downstream ends of which serve as oil feed ports 30aa, 30ab, 30ba, 30bb opening at the outer peripheral surface of the sections to be supported at specific phase regions and the downstream ends of which serve as lubricating oil intake ports 30ac, 30bc communicating periodically with the discharge ports of the oil feed means when the rotating shaft is rotated. The oil feed passages are formed in such a manner that the intake ports communicate with the specific phase regions of the sections to be supported at timing when the rotating reaction acts thereon. <P>COPYRIGHT: (C)2010,JPO&INPIT |
