我矿使用的JT1600/1224型单筒卷扬机,其减速器滑动轴承采用油环封闭式润滑。由于轴承采用封闭式润滑,轴承里面油量的多少,难以直接观察到。加油只能凭经验进行估算。润滑油往往不是加多就是加少,油加多了,造成泄漏严重;油加少了,造成缺油,使轴瓦容易出故障。根据这一情况,我们在减速器轴承油堵螺丝处设计了一种简易的油位指示器。如 I used mine JT1600 / 1224 single drum winch, the reducer sliding bearings with oil ring closed lubrication. As the bearing with closed lubrication, the amount of oil inside the bearing, it is difficult to directly observe. Refueling can only be estimated empirically. Lubricating oil is often not plus more is to add less oil plus, resulting in serious leakage; less oil, resulting in lack of oil, so that bearing easy to malfunction. Based on this situation, we designed a simple oil level indicator at the gearbox oil plug screw. Such as
