钢铝复合接触轨滚动轴承式膨胀接头研制

分析了国内2种膨胀接头的特点,通过滚动轴承式膨胀接头的研制大大降低了其初始滑动力,使安装更为方便,极大地提高了膨胀接头的使用性能,并通过线路试挂及正式应用,效果良好,可推广应用于城市轨道交通接触轨线路。

Development of Rolling Bearing Type Expansion Joints for Steel-aluminum Contact Rail

Analysis of the characteristics of domestic and expansion joints,expansion joints through the rolling bearing greatly reduces the development of its initial sliding force,to make installation easier,greatly improves the performance of the use of expansion joints,and through the line and try to hang formal application,good results can be applied to urban rail transit contact rail lines.
