随着列车的提速和重载,钢轨磨损问题越来越突出。铁路曲线地段上股钢轨侧面磨耗是普遍存在的问题,是曲线上特别是小半径曲线上股钢轨更换的主要原因。钢轨侧磨的同时,车轮轮缘也相应被磨耗,并增加了列车运行阻力,加大了铁路运营成本。为减缓钢轨侧面、轮缘的磨耗,机车车辆部门正在研究开发磨耗型踏面车轮、转向架设置初级悬挂装置、迫导向转向架、径向自导向转向架等。下面讨论工务部门处理曲线上股钢轨侧面磨耗问题的措施。一、铺设耐磨轨。很显然钢轨的侧面磨耗速度与钢轨的材质有关,在小半径曲线上股铺设硬度大、耐磨性和韧性好的合金钢轨、
As the train speed and heavy load, rail wear more and more prominent. Abrasion on the rail side of the railway curve is a common problem, which is the main reason for the replacement of the rail on the curve, especially on the curve of small radius. Rail side grinding at the same time, the wheel flange is also corresponding to wear and increase the train running resistance, increased rail operating costs. In order to reduce the rail side, rim wear and tear, rolling stock department is studying the development of wear-type tread wheels, bogies to set the primary suspension device, forcing the steering bogie, radial self-steering bogies. The following discussion of the work department to deal with curve on the rail side rail wear measures. First, the laying of wear rails. Obviously the side of the rail wear speed and the material of the rail, in the small radius of the curve on the stock laying large hardness, good wear resistance and toughness of the alloy rail,
