SLIDE BEARING |
摘要 |
A sliding bearing 2 has a sliding surface 2a in sliding contact with an outer peripheral surface of a crankshaft 1 (rotating shaft) and a relief portion 4 formed along a circumferential direction on both axial end portions of the sliding surface 2a and retreated outward in a radial direction from the sliding surface 2a. The relief portion 4 is provided with a flat portion 4a formed on the axial end portion and a tapered portion 4b formed so as to become gradually deeper from the flat portion 4a toward a boundary portion between the relief portion 4 and the sliding surface 2a. A lubricant forms a disturbance or a swirl inside the tapered portion 4b and then, flows along the tapered portion 4b so as to form a high-pressure region W by a flow of the lubricant at a position of the flat portion 4a. A temperature of the lubricant can be rapidly raised and also, leakage of the lubricant can be suppressed. |
