Claims (1)
クラツシユリリーフが形成されたクランク軸半割
平軸受において、該クラツシユリリーフ表面の加
工粗さが主たる軸受面である周方向の中間面より
も粗く、かつ、該クラツシユリリーフの加工痕跡
である多数の凹条が周方向に延在していることを
特徴とするクランク軸半割平軸受。 In a half-split crankshaft flat bearing in which a crush relief is formed at both circumferential ends of a semi-cylindrical inner circumferential surface of the bearing, the machining roughness of the crush relief surface is the main bearing surface. 1. A half-split flat crankshaft bearing characterized in that a large number of grooves extending in the circumferential direction are rougher than the surface and are traces of machining of the crush relief.
