摘要
分析了CFH-Ⅱ型翻车机传动齿轮轴承座的座脚螺栓组联接失效(松动)的原因,得出控制和保证合适的螺栓组联接预紧力是防止螺栓联接失效(松动)的关键;依据现场条件,对座脚螺栓进行了设计改进;提出了一种适合现场使用的螺栓预热伸长的装配方法,经实践验证此法是简单可靠的装配方法。
This paper Introduces the cause that the foundation bolt connection is invalid on the pillow block bearing of transmission gear for CFH- II type wagon Tipper. Educes a conclusion that controling and ensuring pre-stress of foundation bolt force is sticking point prevented connection invalidation. According to field condition presents a pre-stress assemblage technics of heatting . It is credible and simple assemblage technic by trying
