摘　　要：柴油机曲臂差的测量在目前船舶领域和电站中起着决定性的作用,曲轴从开始加工至柴油机安装运行前后,都必须测量曲臂差,这就要求使用者时刻关注曲臂差的测量数值。曲臂差(开档差)是柴油机曲轴在上、下、左、右位置时曲臂间一定距离变化的差值。测量曲臂差的目的,就是通过测量曲臂差了解主轴承磨损情况和曲轴轴线的弯曲程度,做到及时维修和调整,使各档主轴承轴线基本同心,使曲轴旋转时不受任何外力影响,以保证柴油机安全可靠运行。The measurement of Diesel Engine Crankshaft Deviation plays a decisive role in the current field of ship and power station, from the beginning to the diesel engine crankshaft processing installation, the crankweb deviation must be measured before and after the operation, which requires measuring value user always pay attention to the crankweb deviation. Crankweb Deviation is a diesel engine crankshaft in the upper and lower, left, right position crankweb a certain distance changes between the deviation. Measurement of crankweb deviation is the purpose, by measuring the crankweb deviation understanding bending degree of main bearing wear and the axis of the crankshaft, timely repair and adjustment, so that each main bearing axis is basic concentric, so that the crankshaft rotates without the influence of external force, so as to ensure the safe and reliable operation of diesel engine.
