JOURNAL BEARING

摘要

To reduce the amount of lubricating oil released (supplied) between the outer circumferential surface of a rotation shaft and the inner circumferential surfaces of pads, so as to reduce the churning loss, and to reduce the bearing loss. The journal bearing comprises: a plurality of pads (13a and 13b) arranged radially inside a lower half-carrier ring (17) at intervals, for receiving load from the rotation shaft; and a plurality of pad stops (14a, 14b, 14c, 14d, and 15) respectively arranged at the circumferentially opposite ends of the respective pads (13a and 13b), for restraining circumferential movements of the respective pads (13a and 13b), wherein, among these pad stops (14a, 14b, 14c, 14d, and 15), the pad stops (14a, 14b, 14c, and 14d) other than the pad stop (15) located in the most forward position in the axial rotation direction of the rotation shaft have functions as oiling nozzles for releasing lubricating oil between the outer circumferential surface of the rotation shaft and the inner circumferential surfaces of the pads (13a and 13b).
