我厂于1982年夏季购进ZL50型装载机三台,其中有一台运转500多小时后,出现变速箱液压油窜入到发动机油底壳内现象。经过解体检查,发现变矩器泵轮连接的分动齿轮中,旋转密封环处有压力油泄漏。油在飞轮壳下的回油孔滞留期,由旋转飞轮齿圈搅动,靠离心力将油甩在飞轮壳的壁面上,从上部壁面流向曲轴尾端,形成流油雨,在曲轴旋转惯性作用下又形成油圈带。在尾端螺旋油槽
I plant in the summer of 1982 ZL50-type loader purchased three, of which more than 500 hours of operation, the gearbox hydraulic oil fleeing into the engine oil pan phenomenon. After the disintegration inspection found that the torque converter pump connected to the transfer gear, rotating seal ring there is a pressure oil leak. Oil in the flywheel shell back to the oil hole retention period, by the rotating flywheel ring agitation, by centrifugal force will be thrown in the flywheel housing wall, from the upper wall to the crankshaft tail, the formation of oil and rain, the inertia of the crankshaft rotation Also formed with oil band. Spiral oil tank at the end
