ク軸半割平軸受。 In a half-split crankshaft flat bearing in which a crush relief is formed over the entire width of both circumferential ends of the semi-cylindrical inner circumferential surface of the bearing, a shallow circumferential groove is formed in the widthwise middle part of the crush relief. At the same time,
It is confirmed that the machining roughness of the crush relief surface is rougher than that of the intermediate surface in the circumferential direction, which is the main bearing surface, and that a large number of grooves, which are traces of machining, extend in the circumferential direction. Features a half-split flat crankshaft bearing.
