BEARING DEVICE, OIL DISTRIBUTION MECHANISM AND METHOD

摘要

PROBLEM TO BE SOLVED: To suppress run-out of oil even when a shaft peripheral speed is increased in a pad type journal bearing device. SOLUTION: The bearing device includes: at least one pad 44 having a bottom recess portion configured to receive at least one retaining head of a journal bearing 40; an oil distribution mechanism configured to inject oil at a leading edge corresponding to a rotating direction of a rotor of the pad 44 to flow towards a trailing edge of the pad 44; and an oil redistribution mechanism on the pad configured to redistribute the oil from the trailing edge of the pad 44 to the leading edge of the pad 44. Thus, run-out of the oil on the pad is suppressed. COPYRIGHT: (C)2011,JPO&INPIT
