对低级修程发车的轴箱油润检修工艺，从系统因素分析，对制约影响油润质量的诸要素，轴瓦、油线、轴油、瓦垫、轴颈以及相互之间组合装配工艺等，进行了全面深入的分析探讨．并结合我段几年来热轴攻关的切身体会，提出了解决低级修程货车热轴问题的最佳工艺．通过实践考证，此工艺是防燃防切工作深入开展的必要前提和基础。 From the system factor analysis, to the factors that restrict the quality of oil lubrication, such as bearing bush, oil line, shaft oil, tile cushion, journal and the combination assembly process among them, Conducted a comprehensive and in-depth analysis and discussion. Combined with my experience of the hot shaft in recent years, I put forward the best process to solve the hot axle problem of the low-grade truck. Through practical research, this process is the necessary prerequisite and foundation for further development of flame-retardant and anti-cutting work.
