摘要
本文通过动平衡实验,对EQ141有平衡块曲轴的动平衡性能进行了研究,并与EQ140曲轴进行对比。研究表明,EQ141曲轴动挠度比EQ140曲轴小,但动挠度仍是EQ141曲轴动不平衡的主要原因,为此,提出了改善曲轴动平衡性能的途径,并对其进行了分析。
The behavior of the dynamic balance of EQ141 crankshafts (with balance weights) is studied through dynamic balance test , and comparison is made with EQ140 crankshafts. Results show the dynamic deflection of EQ141 is smaller than that of EQ140, but this deflection is still the major source of the dynamic unbalance of EQ141. In this connection , suggestions for improving the behavior of crankshaft dynamic balance are proposed.
