曲轴进行动平衡试验是减少柴油机轴瓦磨损,提高运动件使用寿命,减少振动,提高柴油机运转平稳性的关键一环。过去二七机车车辆工厂由于没有曲轴动平衡设备,因此做动平衡时需要借外厂设备,去七个人用将近十天的时间才能完成一根曲轴的动平衡试验。为了适应转
Crankshaft dynamic balance test is to reduce the wear of diesel bearings, improve the life of moving parts, reduce vibration and improve the smooth operation of diesel engine key part. In the past, the No.2 locomotive and rolling stock factory had no crankshaft balancing equipment, so it needed to borrow the external equipment for balancing and go to seven people for nearly ten days to finish the dynamic balance test of a crankshaft. In order to adapt to turn
