半轴是FX1型翻斗车传动系统中的重要零件。一般都要进行热处理,而热处理工艺的适当与否,又将直接影响到半轴的热处理质量。我们对翻斗车的半轴进行了使用情况的调查,据1978年以来的不完全统计,半轴已有部分早期损坏,主要是由于热处理工艺不当。在不变尺寸、材料的情况下,改进了热处理工艺,使半轴的抗扭屈服强度得到提高。一、半轴的失效情况及分析半轴的主要失效部位是花键或花键尾根部与杆交界处断裂占90％左右,其它为法兰圆角断裂。而我们对半轴感应加热淬火只是
Axle shaft is an important part of the drive system of the FX1 dump truck. Generally have to heat treatment, and heat treatment process appropriate or not, and will directly affect the quality of heat treatment of the semi-shaft. We surveyed the use of dumpers’ half-shafts. According to incomplete statistics since 1978, some of the half-shafts had been damaged early, mainly due to improper heat treatment processes. In the same size and material, the heat treatment process is improved so that the torsional yield strength of the semi-shaft is improved. First, the failure of half-shafts and analysis The main failure of the semi-shaft spline or spline is the root of the junction of the Ministry of the bar and about 90% fracture, the other for the flange fillet fracture. And we only semi-induction heating quenching
