曲轴是柴油机的重要零件之一 它承受由活塞通过连杆传来的力,并将活塞的往复运动通过曲柄连杆机构变为旋转运动,将发动机所做的功传递出去。它在工作时受到很大的扭转应力及大小和方向都发生变化的弯曲力,因此,柴油机曲轴对主轴颈、连杆轴颈等的尺寸精度、表面粗糙度及主要部位的相关精度都要有很严格的检验要求。柴油机曲轴连杆轴颈的夹 The crankshaft is one of the important parts of a diesel engine. It withstands the force transmitted by the piston through the connecting rod and transforms the reciprocating motion of the piston into a rotating motion through the crank-rod mechanism to transmit the work done by the engine. It is subject to a lot of work in the torsion stress and the size and direction of the bending force changes, therefore, the diesel engine crankshaft, connecting rod and other dimensional accuracy, surface roughness and the main parts of the relevant precision must have Very strict inspection requirements.
