1 问题的提出牵引电动机主动齿轮系内燃机车走行部传递动力的关键部件之一,它与电机轴的装配形式采用的是圆锥轴过盈配合,在机车满负荷运行时,其承担着列车大约410ｋＷ(Ｃ型车为480ｋＷ)的牵引力。如果机车在运用当中出现主动齿轮松脱或崩裂,特别是机车在低速重载牵引工况下,?
1 PROBLEM PROPOSED Traction motor driving gear train is one of the key components of the transmission running part of the diesel locomotive. The assembly form of the motor shaft adopts the interference fit of the cone shaft. When the locomotive is running at full load, it takes about 410kW (C-type car is 480kW) traction. If the locomotive in the use of active gear loosen or crack, especially locomotive traction at low speed and heavy load conditions?
