目前在地质勘探工作中所使用的柴油机,因曲轴折断而发生机械事故的现象,还是比较普遍的.由于曲轴工作条件以及它所受的复杂应力的影响,其发生折断的原因也较复杂.因此必须根据具体情况采取相应的措施.笔者仅将个人所考虑的一些初步意见,提出来和大家共同研究.一、曲轴折断的原因1.中心线不一致由于曲轴的主轴轴颈的中心线和相接轴的中心线不一致,虽然在正常负荷时无事故征兆,但因长期运转,材料本身的疲劳现象,也往往使曲轴折断.这主要是由于按装的不正确.如果是单机不是机组,它虽
The diesel engine currently used in geological exploration work is mechanically damaged due to the crankshaft breaking, and it is still relatively common. Due to the working conditions of the crankshaft and the complex stress it receives, the reason for the breakage is also complicated. Must take corresponding measures according to the specific circumstances. The author will only consider some of the preliminary views of individuals, and come up with everyone to study together. First, the crankshaft break causes 1. The centerline is inconsistent due to the crankshaft spindle shaft centerline and phase The centerline of the shaft is inconsistent. Although there are no accident signs during normal load, due to the long-term operation, the fatigue phenomenon of the material itself often causes the crankshaft to break. This is mainly due to incorrect installation. If it is not a single unit, it is
