齿轮箱失效会导致内燃动车组和车辆损失运营时间和修理费。这种失效通常源于设计问题或制造中的误差、材料质量、热处理、组装缺陷或运输中的损坏。必须运用熟练的技巧判定齿轮箱最可能失效的原因。当出现瑕疵时,失效就会扩散开来,导致运营列车其他部件的损坏。例如:在某个轴承中有某个轴承罩失效,就会导致碎片损坏齿轮。这说明初始检查有可能提供一种误导性诊断,因此齿轮箱部件应进行规范的定期检查,以确保在思路上有一个 Failure of the gearbox will result in loss of operating hours and repairs for the DMUs and vehicles. This failure often results from design problems or manufacturing errors, material quality, heat treatment, assembly defects, or damage in transit. Expertise must be used to determine the most likely cause of gearbox failure. When a flaw occurs, the failure spreads, causing damage to other parts of the operating train. For example, failure of one of the bearing housings in a bearing can cause debris to damage the gear. This shows that the initial inspection may provide a misleading diagnosis, so gearbox components should be regularly checked to ensure that there is a mentality
