磨矿作业广泛应用于矿山、冶金、电力、建材行业,其中球磨机是常见的用途最广、数量最多的粉磨设备之一。球磨机的构造虽略有差异,但其中常见的轴承形式有液体动压、静压、动静压三种滑动轴承。三种滑动轴承的结构基本相同,主要有轴瓦(都只有下瓦)、轴承座、轴承盖、润滑及冷却系统所组成。本文主要探讨球磨机三种轴承形式的特点。 Grinding operations are widely used in mining, metallurgy, electric power, building materials industry, of which the ball mill is the most widely used, the largest number of grinding equipment. Although there are slight differences in the structure of the ball mill, but there are common forms of fluid dynamic pressure hydrostatic, static pressure, static and dynamic pressure of three sliding bearings. Three kinds of plain bearing structure is basically the same, mainly bearing (all only under the tile), bearing seat, bearing cover, lubrication and cooling system. This article mainly discusses the characteristics of three kinds of ball mill bearings.
