近年来,车辆部门广大职工由于采取了很多防止燃轴的有力措施,燃轴事故有所减少,但仍然是威胁车辆安全运行的一个因素。导致车辆燃轴的因素是多方面的,本文仅就轴瓦白合金的性能作一初步探讨。一、课题的提出和对轴瓦白合金的要求 (一)现状和问题 1.多年来,每发生燃轴事故,就化验白合金的化学成份。但是燃轴与白合金的理化、机械性能的关系没有科学的试验数据。 2.车型结构有了发展,载重量增加了,但轴瓦合金没有改进,它能否适应新的运行
In recent years, the majority of workers in the vehicle department have taken a lot of measures to prevent ignition of the combustion shaft, reducing the number of accidents on the combustion shaft, but are still a factor that threatens the safe operation of the vehicle. The factors leading to the combustion of the vehicle shaft is multifaceted, this paper only on the bearing bush white metal for a preliminary study. First, the proposed project and the requirements of bush white alloy (a) the status quo and problems 1. Over the years, each occurrence of combustion shaft accident, the chemical composition of the white metal assay. However, there is no scientific experimental data on the relationship between the burning shaft and the physical and chemical properties of the white metal and mechanical properties. 2. With the development of vehicle structure, load increased, but there is no improvement in bearing alloy, it can adapt to the new operation
