S195柴油机的曲轴油封漏油是老大难问题。为了从根本上解决,我们采用甩油圈的办法,取得了良好效果。柴油机运转时油封保持不动,受曲轴轴向间隙的影响,曲轴在油封唇口处将保持一定的窜动量,这就增加了曲轴油封渗漏的可能性。在油封与主轴承之间安装甩油圈,如图1所示,除了可以直接阻止润滑油沿曲轴轴颈表面渗出油封唇口外,还在于:当柴油机运转时,从曲轴与主轴承之间溢出的润滑油,通过甩油 S195 diesel engine crankshaft oil seal leakage is the crux of the problem. In order to fundamentally solve, we use the method of rejection oil circle, and achieved good results. Diesel engine oil seals remain intact, affected by the crankshaft axial clearance, the crankshaft in the lip seal lip will maintain a certain amount of movement, which increases the possibility of crankshaft oil seal leakage. Install the oil slinger between the oil seal and the main bearing. As shown in Fig. 1, in addition to directly preventing oil leaking out of the oil seal lip along the crankshaft journal surface, it also lies in that when the diesel engine runs, Spilled oil through oil rejection
