摘要： PROBLEM TO BE SOLVED: To provide a lubricating fluid discharging mechanism capable of suppressing a rise in temperature of a bearing.
SOLUTION: The lubricating fluid discharging mechanism is for discharging a lubricating fluid used for lubricating the bearing of a rotating shaft 10 in a non-contact state to the rotating shaft. The lubricating fluid mechanism is provided with a feeding hole 4, which is provided to a bearing face 2 of the bearing and to which the lubricating fluid is fed, and a groove 14 formed to the bearing face on the upstream side in the rotation direction Y1 of the rotating shaft from the feeding hole and discharging the lubricating fluid, which flows along in the rotation direction from the upstream side, from the bearing face. A cross-sectional area of a flow passage of the lubricating fluid, which flows along in the rotation direction from the upstream side, becomes relatively large compared with that of on the upstream side in the groove. Therefore, the pressure of the lubricating oil is lowered. The direction of the flow of the lubricating oil is changed into the groove in a state of accelerating the flow of the lubricating fluid. As a result, a flow rate flowing to the feeding hole side is reduced.
