目 前 ,国内绝大部分选矿厂的球磨机回转主轴仍采用巴氏合金的滑动轴承 ,不仅摩擦功耗大 ,而且使用寿命短。液力静压轴承由于在低速或静止条件下都可以实现完全液体润滑 ,两摩擦副之间始终存在着一层有压油膜 ,因而具有承载能力大、运动精度高、抗振性能好、使用寿命长、摩擦功 At present, the ball mill rotary spindle of the vast majority of domestic concentrator still adopts the plain bearing of Babbitt alloy, which not only has large frictional power consumption but also short service life. Hydrostatic bearing can achieve complete liquid lubrication under low or static conditions. There is always a layer of pressure oil film between the two friction pairs, so it has the advantages of large bearing capacity, high movement precision, good anti-vibration performance and long service life Long, friction work
