减少异型鱼尾板裂纹延长使用寿?/h3>

发布时间 : 2018-05-23    
    异型鱼尾?/a>就是众多鱼尾板中的一种,而且异型鱼尾板也称为轨道接头夹板?a href="/supply/493.html" target="_blank">道夹?/a>,在轨道接头处起连接作用。分为轻轨、重轨和起重轨。鱼尾板是一种用于轨道与轨道之间连接使用的连接紧固件。在使用异型鱼尾板时,裂纹是较常见的一种故障,当裂纹增多,加剧时,则需要更换异型鱼尾板。因此,只要能减少异型鱼尾板,才能有效的延长使用寿命?br />     1、降低摩擦系数。这可以通过多方面的渠道来实现,例如进行表面处理,改善表面质量或在材料接触表面加入某种形式的中介物等?br />     2、减小滑移振幅。即是减小钢轨与鱼尾板间相对作用的幅度。可以通过钢轨与鱼尾板间紧固力的调整减小滑移振幅,也可以通过改善接头状况,减小冲击作用来减小滑移振幅。据观察,胶接鱼尾板很少发生断裂现象,这也表明了控制滑移振幅对鱼尾板寿命的影响?br />

    3、减小接触压力。影响接触压力的因素比较多,减小接触压力将减小钢轨与鱼尾板间相互作用力的强度。工况条件、轴重、车速等都会对其有较大的影响,其中有些是在工作条件下必须承受的,如载荷、车速等,有些是可以通过改善工况条件加以调整的,如保持适当的轨缝、良好的接头养护等。另外,钢轨与鱼尾板配合面的儿何形状也将影响到接触压力的大小?

    希望大家能够通过以上信息的介绍,了解减少异型鱼尾板裂纹的方法,有效延长使用寿命。除此之外,我公司提供各种铁路配件,对于铁路配件各方面的信息,也非常的了解,因此,欢迎广大新老用户与我公司联系,我公司不仅能根据您的需求,推荐及提供适合的铁路配件,还能解答大家对铁路配件的疑惑?br />
