内燃机曲轴作为单一零件的动平衡精度已成为所有制造厂所必需实现的指标之一,而与内燃机性能直接相关的却是曲轴与飞轮总成后的动平衡精度.随着内燃机的工作转速的提高,曲轴飞轮总成的动平衡精度的提高成了大多数制造厂所关注的问题. Crankshaft as a single part of the internal combustion engine balancing accuracy has become a must for all manufacturers to achieve one of the indicators, and is directly related to the performance of the internal combustion engine crankshaft and flywheel assembly is the dynamic balancing accuracy.With the increase in operating speed of the internal combustion engine , Crankshaft flywheel assembly dynamic balancing accuracy has become the concern of most manufacturers.
