本文指出了我国机车车辆车轮轮缘踏面外形的检验、测量方法及其量具所存在的问题。参照国外有关标准并结合我国车轮生产与运用的实际情况,研制了新型轮缘踏面外形检查器。这种检查器设计合理,结构紧凑,一器多用。由于轮缘厚度测量基准选取合理,使用该新检查器测量可减少轮缘磨耗到限的车轮数量,延长车轮使用时间?具有显著的经济效益。 This paper points out the inspection of the rim shape of wheel rim in our country, the measurement method and the problems existing in its measuring tools. Reference to the relevant foreign standards and the actual situation of China’s wheel production and use, developed a new wheel tread profile checker. This checker design is reasonable, compact structure, a multi-purpose. With a reasonable selection of rim thickness measurements, this new checker measurement reduces the number of wheels that are worn to the rim and extends wheel life, with significant economics.
