Tilting-pad journal bearing device

摘要

Disclosed is a highly reliable tilting-pad journal bearing device constructed to suppress vibration by improving a damping effect through a lubricating oil film, and thus to improve cooling performance for bearing pads without increasing the number of parts required. The tilting-pad journal bearing device includes a plurality of bearing pads (2) in a circumferential direction at an inner circumferential side of a casing (1), and supports a rotary body (4); at least one of the bearing pads (2) includes an oil-through groove (8) circumferentially extending along an outer circumferential surface of the bearing pad, the groove circumferentially extending through from an end face of the pad to its opposite end face.
