1. An oil supply mechanism of a rotating machinery comprising a rotating shaft, the oil supply mechanism comprising:
a main oil supply passage formed in the rotating shaft substantially in an axial direction of the rotating shaft; and
a bypass oil passage in communication with the main oil supply passage and allowing a part of lubricating oil in the main oil passage to flow out via the bypass oil passage,
wherein the bypass oil passage extends substantially transversely to the rotating shaft, and the bypass oil passage is configured such that a radial distance between an outlet of the bypass oil passage and an axis of the rotating shaft is greater than a radius of the rotating shaft,
wherein the bypass oil passage comprises a first passage portion and a second passage portion connected to each other, the first passage portion is in direct fluid communication with the main oil supply passage, and a cross-sectional area of the first passage portion is greater than a cross-sectional area of the second passage portion so that the bypass oil passage is formed as a stepped passage.
