钢轨啃伤缺陷是万能重轨生产中常见缺陷,特征各异,形成因素众多,现场查找和消除时间长。本文描述了运输辊道啃伤缺陷的特征、形成过程,同时对缺陷的形成及大小进行了力学上的分析计算,对缺陷的出现机组进行了分析。通过现场试验证明了本文分析的合理性及计算的准确性,可为该类缺陷的及时查找及消除提供依据。 Rail bite damage defects are common defects in universal rail production, different characteristics, the formation of many factors, the scene to find and eliminate a long time. This paper describes the characteristics and forming process of nibbling defects on transportation roller conveyors, analyzes and calculates the formation and size of defects at the same time, and analyzes the occurring units of defects. Through the field test, the rationality of the analysis and the accuracy of the calculation are proved, which can provide a basis for timely finding and eliminating such defects.
