    Abstract: A slide bearing in the present invention is formed in a cylindrical shape and has an inner peripheral surface sliding along an axis, the slide bearing includes: a first groove in which the extension direction is a direction having a component in a circumferential direction on the inner peripheral surface; and at least two second grooves that are branched from the first groove and in which the extension directions are directions each having a component in an axial direction at least within a predetermined range from the first groove. Within a predetermined range from an end opposite to the first groove of the second groove, the width or the depth gradually decreases toward the end.

    Abstract: 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.

    Abstract translation: 滑动轴承2具有与曲轴1(旋转轴)的外周面滑动接触的滑动面2a和在滑动面2a的两轴向端部沿圆周方向形成的凸部4, 从滑动面2a的径向。 释放部分4设置有形成在轴向端部上的平坦部分4a和形成为从平坦部分4a朝向浮雕部分4和滑动表面2a之间的边界部分逐渐变深的锥形部分4b。 润滑剂在锥形部分4b内形成干扰或漩涡,然后沿着锥形部分4b流动,以便通过在平坦部分4a的位置处的润滑剂流动形成高压区域W. 润滑剂的温度可以迅速升高,并且可以抑制润滑剂的泄漏。
