摘要： Disclosed is a cylindrical sliding bearing consisting of an upper and a lower half bearings, which supports a crankshaft of an internal combustion engine. An oil groove is formed circumferentially on an inner surface of at least the upper half bearing. There are provided circumferential grooves formed by boring machining on the overall inner surfaces of the half bearings. Each of the circumferential grooves existing in circumferential both end regions has a larger cross-sectional area than the grooves existing in other regions receiving predominantly operational load when the crankshaft rotates. The upper half bearing is chamfered at a front inner end edge with respect to a rotational direction of the crankshaft supported by the sliding bearing, and the lower half bearing is also chamfered at an inner end edge adjacent to the above front inner end edge, an area of the respective chamfered portion being the same as the 0.15 mm to 0.4 mm length chamfer corner area.
摘要翻译：公开了一种由支撑内燃机的曲轴的上半轴承和下半轴承组成的圆柱形滑动轴承。在至少上半轴承的内表面上周向形成油槽。在半轴承的整个内表面上设置有通过镗孔加工形成的周向槽。存在于周向两端区域中的每个周向凹槽具有比当曲轴旋转时主要承受操作负载的其它区域中存在的凹槽更大的横截面面积。上半轴承在相对于由滑动轴承支撑的曲轴的旋转方向的前内端边缘处被倒角，并且下半轴承在邻近上述前内端边缘的内端边缘处也被倒角，相应倒角部分的面积与0.15mm至0.4mm长的倒角角区域相同。
