摘　　要：针对某配置双电马达起动的柴油机起动小齿轮及飞轮齿圈铣齿的故障,从引起铣齿故障的可能因素进行排查,总结出可能的故障因素包括齿轮齿圈不匹配、啮合间隙超差、平行度超差、双电马达不同步、操作失误以及电马达自身故障等。排查结果表明:起动电马达单向器垫圈渗碳不合格,使单向器垫圈在起动瞬间承受的冲击力超过其承受极限,是导致起动小齿轮及飞轮齿圈铣齿故障的根本原因。For the malfunction of starting pinion and flywheel ring gear milling of a diesel engine with dual electric motor starting, the possible factors causing the malfunction are investigated, including mismatch of ring gear, excessive meshing clearance, excessive parallelism, asynchronism of dual electric motor, operation error and motor fault itself. The results show that the unqualified carburizing of the unidirectional washer of the starter motor causes the impact force of the unidirectional washer to exceed its endurance limit at the moment of starting, which is the root cause of the malfunction of milling teeth of the starter pinion and flywheel ring gear.
