摘要： A crank bearing is disclosed that includes a semicircular upper bearing and a semicircular lower bearing, which can be split from each other. The upper bearing includes a first oil passage for introducing engine oil from the outside to a gap between the crank bearing and a crank journal, and a second oil passage for permitting the engine oil to flow in the circumferential direction of the crank bearing. The first oil passage includes an inner circumference opening, which is open to the inner circumference of the main bearing. The upper bearing includes a non-undercut portion in which no oil passage is formed on the trailing side of the inner circumference opening in the rotational direction of the crank journal. A chamfer oil passage for discharging the engine oil in the second oil passage to the outside from the axial direction of the crank bearing is provided in at least one of the lower bearing and a region on the proceeding side of the circumference opening in the rotational direction of the crank journal.

摘要翻译： 公开了一种曲柄轴承，其包括可以彼此分离的半圆形上轴承和半圆形下轴承。 上轴承包括用于将发动机油从外部引导到曲柄轴承和曲柄轴颈之间的间隙的第一油路，以及允许发动机油沿曲轴轴承的圆周方向流动的第二油路。 第一油路包括与主轴承的内周面开口的内周开口。 上轴承包括在曲轴轴颈的旋转方向上在内圆周开口的后侧没有形成油路的非底切部。 在所述下轴承和所述周向开口的沿所述旋转方向的行进侧的区域中的至少一个中设置有用于将所述第二油路中的发动机油从所述曲柄轴承的轴向排出到外侧的倒角油通道 的曲柄轴颈。
