Abstract
Method, pad and bearing device for oil redistribution. The bearing device includes a ring having at least one retaining head, at least one pad disposed inside the ring and having a bottom recess portion configured to receive the at least one retaining head, an oil distribution mechanism configured to inject oil at a leading edge of the at least one pad to flow towards a trailing edge of the at least one pad, and an oil redistribution mechanism on the at least one pad configured to redistribute the oil from the trailing edge of the at least one pad to the leading edge of the at least one pad. The leading edge is a first edge and the trailing edge is a second edge of the at least one pad encountered when traveling along a circumference of the ring in a direction of rotation of a rotor supported by the at least one pad.
