Abstract: Provided is a sliding member which has high seizure resistance though an overlay layer comprising Ag as the main component is used therein. The sliding member of an embodiment comprises a base and an overlay layer which is disposed on the sliding-side surface of the base and which comprises Ag as the main component and contains Al. The overlay layer comprising Ag as the main component is relatively soft. Due to this, the overlay layer comprising Ag as the main component can ensure high seizure resistance even when the use of Pb is avoided. Furthermore, the overlay layer comprising Ag as the main component has excellent thermal conductivity. Due to this, frictional heat generating at the sliding part rapidly dissipates to the base side.

Abstract: In a copper-based slide member in which needle-shaped Mn—Si based compounds are dispersed in a brass structure, 50% or more of a total number of the needle-shaped Mn—Si based compounds having lengths of 50 μm or more in a major axis direction are constituted of a plurality of small particles. Thereby, even if the needle-shaped Mn—Si based compounds fall off during sliding, the small particles which constitute the needle-shaped Mn—Si based compounds may fall off. Thus, the frequency of falling off of the coarse needle-shaped Mn—Si based compound which damages a shaft and a bearing is decreased. Therefore, seizure hardly occurs.
Abstract translation: 在针状Mn-Si系化合物分散在黄铜结构体的铜基滑动部件中，在长度为50μm以上的针状Mn-Si系化合物的总数的50％以上 长轴方向由多个小粒子构成。 因此，即使针状Mn-Si系化合物在滑动时脱落，构成针状Mn-Si系化合物的小颗粒也可能脱落。 因此，损伤轴和轴承的粗针状Mn-Si系化合物的脱落频率降低。 因此，几乎不发生癫痫发作。

Abstract: A main bearing for a crankshaft of an internal combustion engine comprises a pair of semi-cylindrical bearings. An oil groove extends on an inner circumferential surface of one semi-cylindrical bearing in a circumferential direction so that the center thereof in an axial direction aligns with that of an inlet opening of a lubricating oil path in a journal section of the crankshaft. The oil groove does not extend up to an axial direction groove formed at a joint portion of the semi-cylindrical bearings so that a separation inner circumferential surface extends between a circumferential direction end portion of the oil groove and the axial direction groove. The length of the separation inner circumferential surface is smaller than that of the inlet opening in the circumferential direction.
