近年来,CC195柴油机折断连杆螺栓在我们这里时有发生。6台CC196连杆螺检折断的具体原因是,5台是因为连杆瓦间隙过大造成,有拉瓦的前科,连杆轴颈均有严重磨损,有的连杆瓦合金层基本磨光,一般的轴瓦间隙均达0.80毫米以上,最大的约2毫米;另一台是因为连杆松动造成的。连杆螺栓折断后,6台中有4台打坏了机体,有3台捣伤了曲轴连杆轴颈,连杆全部报废。有的打坏了气缸套和平衡轴。 CC195柴油机的连杆螺栓为什么容易折断呢?从理论上讲,该机转速高一些,曲轴回转半径大一些,工作中运动件的自然磨损也大些。此外,根据各次断连杆螺栓的分析和用户反映,CC195柴油机机温较高,机油变质较快。有的机子机油用不到半个月就变成了糊状,这样使润滑条件很快变坏,有的用一年左右的
In recent years, CC195 diesel engine broken rod bolts occur in us from time to time. 6 sets of CC196 connecting rod screw cut off the specific reason is that 5 units because of connecting rod shim caused by too much, with Lava front section, connecting rod journals have serious wear and tear, some rod and bearing alloy layer of the basic polished , The general bearing gap up to 0.80 mm above the maximum of about 2 mm; the other is because the connecting rod loose caused. After the connecting rod bolt was broken, 4 of the 6 sets broke the body, 3 of them smashed the crankshaft connecting rod journal and all the connecting rods were discarded. Some broke the cylinder liner and balance shaft. CC195 diesel engine connecting rod bolts Why easily break it? In theory, the aircraft speed higher crankshaft turning radius larger, the natural wear and tear of moving parts are larger. In addition, according to the analysis of the broken link bolt and user feedback, CC195 diesel engine temperature is higher, oil deterioration faster. Some machine oil in less than two months into a paste, so that the lubrication conditions quickly deteriorate, and some use about a year
