桥式起重机车轮圆柱工作表面处的两凸边与轨道两侧发生严重摩擦,即车轮啃轨,是可能发生的突出事故之一(如图1)。啃轨所带来的后果,轻则是车轮及轨道磨损,缩短轨道及车轮的寿命;重则使车轮跑出轨道,发生出轨事故,造成机损或人员伤亡。造成啃轨的原因多而复杂。本文拟对常见的啃 One of the outstanding accidents that may occur is the serious friction between the two convex edges of the bridge crane working surface and the two sides of the rail, that is, the wheel gnawing. Gnawing the consequences of rail, ranging from the wheel and track wear and tear, shortening the life of the track and wheels; heavy then the wheels ran out of track, derailment accident, resulting in machine damage or casualties. Cause chewing rail because of the many and complex. This article is intended to common bite
