To provide a rotating machine which can ensure the sufficient load sustainability in a journal bearing, prevent burnout under the conditions of high peripheral velocity and high bearing pressure, and consistently perform the operation for a long time by making use of the bearing.
In order to set the temperature of lubricating oil at a bearing inlet to be substantially equal to the temperature of lubricating oil fed from an oil port, the lubricating oil adhering to a shaft, passing through a load surface and flowing into the oil feed port is discharged before the oil feed port to prevent the increase in excessive temperature of the load surface of the bearing. More specifically, an oil discharge port for discharging the lubricating oil adhering to the shaft, passing through the load surface and flowing in is provided in a range of the bearing sliding surface where no oil film pressure is generated.
