蒸汽机车摇鞍式导从轮轴瓦赶偏和发热是影响机车走行部分质量的一个因素。目前,虽然已经有了一些处理轴瓦赶偏和发热的经验,但由于轴瓦赶偏和发热涉及的部位较广,如何掌握其变化规律,分析其产生原因,以及采取相应的措施来消除这类故障,仍是蒸汽机车检修工艺中急待探讨的问题。尤其是现在导从轮转向架检修工艺不够完善、走行部分各部件装配工艺尚未全面推行的情况下更为突出。 Steam locomotive rocker-driven from the wheel bearing deviation and fever is one of the factors that affect the quality of the running part of the locomotive. At present, although there have been some experiences dealing with the deviation and heating of the bearing bush, due to the wide range of parts involved in the axial deviation and heat generation of the bearing bush, how to grasp the variation rule, analyze the causes, and take corresponding measures to eliminate such faults , Is still an issue to be explored in the steam locomotive maintenance process. In particular, the current steering gear from the wheel overhaul process is not perfect, walking some of the components of the assembly process has not yet fully implemented the case even more prominent.
