根据静动压混合轴承的工作原理,针对被改造设备的具体结构,采取了不换轴、不换瓦,只对原轴瓦做简便的补充加工及增设单独润滑装置的作法,将M7140大型平面磨床磨头的普通滑动轴承改造为静动压混合轴承。实践表明取得了良好的效果(见下表)。 According to the working principle of hydrostatic mixed bearing, according to the specific structure of the equipment to be rebuilt, adopting the method of not changing the shaft, changing the tile, simply supplementing the original bearing shell and adding a separate lubricating device, the M7140 large surface grinder Grinding head of ordinary plain bearings into static and dynamic pressure hybrid bearings. Practice shows that good results have been achieved (see table below).
