过去在我段蒸汽机车架修车中,煤水车轴瓦热的现象一直是大老难问题,在月产十八台架修车中就有十五、六台机车需在回送途中派人去检修轴瓦,甚至有的几次返回重新挂瓦,造成机车不能投入运用,同时也影响了架修进度。经研究确认,尽管刮研的瓦与轴的接触面达到80％以上,但轴不易把油代到轴瓦之间形成油膜, In the past in my section of steam locomotive repair car, coal-water truck bearing heat phenomenon has been a big problem, in the monthly production of 18 gantry repair car there are 15 or 6 locomotives to send people to send back in the way Repair bearing, and even some return to re-hang tile, resulting in locomotive can not be put into operation, but also affected the progress of the build. The study confirmed that, despite scratching the tile and the shaft contact surface reached more than 80%, but the shaft is not easy to oil on behalf of the bearing formed between the oil film,
