针对铁路货车轮对压装过程中出现的烧轴、烧孔现象,以美国西蒙斯自动轮对压装机为例,通过分析认为车轴及轮毂孔加工、压装过程受力不均匀或别劲、压装介质的使用是其主要原因,通过改进加工工艺、优化轮对压装工艺等措施,减少了轮对压装烧轴、烧孔问题的发生。 Aiming at the phenomena of burning shaft and burning holes in the loading process of railway wagon wheels, taking the Simmons automatic wheel press machine in the United States as an example, through analyzing that the machining process of the axle and hub bores and the pressing process are not even or forceful, The use of press-fit media is the main reason for this. By reducing the processing technology and optimizing the wheel press-fit process, the wheel-mounted press-burning shaft and the burning holes are reduced.
