Experimental Study in Screening and Matching of Disc-brake Pair Materials of Drilling Rig

  • 摘要: 在 MMW- 1型摩擦磨损试验机上 ,通过变温摩擦磨损特性试验 ,对优选出的 2种刹车盘表面堆焊材料和研制出的 2种刹车块材料进行了选配 ,并对各刹车副的摩擦学性能进行了分析与评价 .结果表明 ,摩擦偶件对刹车副材料的摩擦学性能有一定的影响 ,因此在进行材料的选配试验时应考虑偶件的匹配问题 .优选出的 2种表面堆焊材料与所研制的 2种刹车块材料组成摩擦副时具有较高的平均摩擦系数和热摩擦系数以及优良的高温耐磨性能 ,其中第二种表面堆焊材料与所研制的第二种无石棉刹车块材料组成摩擦副时的摩擦学性能指标最优 ,可以作为选配出的最优刹车副材料

     

    Abstract: Two different heaping weld materials of brake disc were obtained by optimization process, and two different materials of brake block were developed. All the developed heaping weld materials of brake disc and brake block materials were screened and matched by experimental investigation of the variable temperature friction and wear characteristic with an MMW 1 friction and wear tester. The tribological properties of the braking discs and blocks were comparatively evaluated as well. As the results, the tribological performance of the braking pair was affected to some extent by the matching of the frictional pair materials.The two different heaping weld material discs matched with the two brake-blocks showed higher average and thermal frictional coefficients as well as good wear-resistance at high temperature.The best tribological behavior was observed for the frictional pair compsed of the second welding material and the second asbestos-free brake block composite.Thus it could be screened and used as the optimum disc-block braking pair to be used in drilling rig.
