S195柴油机的上下平衡轴轴承,经多次拆装或由于加工精度等原因,往往产生轴承跑外圈现象,如不及时修复,机体上的轴承座孔会越跑越大,致使孔用挡圈磨薄损坏、平衡轴窜动,并且产生很大的噪音和振动。除轴承拉毛和镗孔镶套修复外,笔者在几台机车上采用下述新法,效果良好,自此从未再发生过跑外圈现象。具体步骤如下:①在205轴承的外圈上(约120°)用砂轮打磨出两道断面为三角形的沟槽,如 S195 diesel engine up and down balance shaft bearings, after repeated disassembly or due to processing accuracy and other reasons, often run the outer race bearing phenomenon, if not repaired in time, the body bearing hole will run more and more large, resulting in the hole ring Grind and damage, balance the shaft to move, and produce a lot of noise and vibration. In addition to bearing bristles and boring set repair, the author in several locomotives using the following new law, the effect is good, since then never happened to run the outer ring phenomenon. Specific steps are as follows: ① 205 bearing outer ring (about 120 °) polished with a grinding wheel two triangular grooves, such as
