<p>PROBLEM TO BE SOLVED: To provide a slide bearing device capable of reducing bearing loss while securing reliability of a bearing device even when rotational vibration of a rotating shaft occurs due to external factors such as giant earthquake and breakage of another part of a rotary machine.SOLUTION: A slide bearing device has an upper half bearing, a lower half bearing 2b connected to a lower portion of the upper half bearing, and an oil removing groove 7 formed on a sliding face of the lower half bearing 2b and extending from a central portion in a bearing width direction toward both side faces of the bearing, and supports a rotating shaft of a rotary machine. The oil removing groove 7 is disposed at a downstream side in the rotating direction of the rotating shaft with respect to an oil film pressure generating part of the sliding face of the lower half bearing, an end portion in the bearing width direction of the oil removing groove 7 is positioned at a downstream side in the rotating direction of the rotating shaft with respect to the central portion in the bearing width direction, and a sliding face 9b is disposed at a downstream side in the rotating direction of the rotating shaft, of the oil removing groove of the lower half bearing.</p> |
