(一)前言在功率较大的液力传动内燃机车中,走行部分通常都是采用转向架式的。这种转向架式的液力传动内燃机车,从柴油机、液力传动箱到机车动轴间,广泛应用了万向轴传动,因此万向轴便成为液力传动内燃机车的重要部件之一。万向轴由花键套叉头、花键轴叉头、万向轴法兰、轴承盖、十字销和万向轴轴承等组成。万向轴轴承是一种无内圈的双列圆柱滚子轴承,十字销轴颈表面直接作为滚动面,它的
(A) Preface In the hydraulic power drive diesel locomotive, the traveling part is usually used bogie type. This bogie hydraulic transmission diesel locomotive widely applies the universal shaft drive from the diesel engine, the fluid transmission box to the motor shaft of the locomotive. Therefore, the universal shaft becomes one of the important parts of the hydraulic drive diesel locomotive. Cardan shaft from the spline sets of fork, splined shaft fork, cardan shaft flange, bearing caps, cross pin and universal shaft bearings and other components. Cardan shaft bearing is a kind of inner ring without double row cylindrical roller bearings, cross pin journal surface directly as a rolling surface, it’s
