一、机车牵引齿轮载荷性质特点: 内燃机车牵引齿轮是机车驱动的重要部件。由于机车结构的限制,它必须在十分有限的空间里向轮对传递机车的全部牵引力,齿轮戴荷大(东风4机车牵引齿轮最大静载荷达10388公斤),运转速度高(在机车速度为100公里/小时时,东风4机车牵引齿轮节圆上的西周速度V=20.32米/秒);对于采用刚性轴悬式牵引电动机悬挂结构的转向架,齿轮还将承受线路与轮对间的剧烈振动冲击所带来的附加冲击载荷。除此之外,还由于:1、作用在车轴两端机车静载荷和线路冲击振动所引起的动载荷造成的车轴(即从动齿轮轴)弯曲变形;2、悬
First, the locomotive traction gear load characteristics: Locomotive traction gear is an important part of the locomotive drive. Due to the limitation of the locomotive structure, it must transmit the full tractive force of the locomotive to the wheelsets in a very limited space. The load of the locomotive Daihe Da (the maximum static load of the traction of the Dongfeng 4 locomotive is 10,388 kg) and the running speed is high (when the locomotive speed is 100 Km / h, Dongfeng 4 locomotive traction gear pitch circle on the Western Zhou Dynasty V = 20.32 m / s); for rigid axle suspension traction motor suspension structure of the bogie, the gear will also withstand the severe vibration between the line and the wheel set Impact of the additional impact load. In addition, but also due to: 1, the role of the axles at both ends of the axle static load and line shock vibration caused by the dynamic load caused by the axle (ie driven gear shaft) bending deformation; 2, hanging
