TWO-PIECE TYPE SLIDING BEARING DEVICE AND ROTARY MACHINE

摘要

PROBLEM TO BE SOLVED: To provide a two-piece type sliding bearing device capable of lowering a bearing temperature by efficiently draining high temperature lubricating oil likely to circulate in a bearing to a bearing external part. SOLUTION: This two-piece type sliding bearing device is formed with an oil drain groove 14 formed in the axial direction on the front side in the rotational direction of a cooling groove 17 in an upper half beating 2, and an oil drain hole 13 penetrating the bottom surface of the oil drain groove 14 and the outer peripheral surface of the upper half bearing 2 for draining the lubricating oil existing at the inner peripheral side of an upper half bearing to the outer peripheral side of the upper half bearing 2 from the inner peripheral side of the upper half bearing 2.
