轴承是用来支撑的部件，也是用来支承轴上回转的零件，轴承的种类按摩擦性质分：有滑动轴承和滚动轴承；按承受载荷的方向分：有向心轴承、推动轴承、向心推力轴承等。
The bearings are used to support the parts, which are also used to support the rotating parts of the shaft, the type of bearing is divided by the friction property: the sliding bearings and rolling bearings; The direction of the load: the bearing, the bearing, the thrust bearing, etc.

滑动轴承是一种滑动摩擦性质的轴承，特点是工作平稳、可靠噪声小、能承受重载荷和较大的冲击载荷，根据结构形式不同可分为整体式、剖分式和瓦块式等。
Sliding bearing is a kind of sliding bearing grinding quality, characteristic is stable, reliable, low noise, can withstand heavy loads and large impact load, according to different can be divided into the integral structure, split and tile type, etc.

 
（1）整体式滑动轴承的装配

整体式滑动轴承俗称轴套，也是滑动轴承中最简单的一种形式，主要采用压入和锤击的方法来装配，特殊场合采用热装法，多数轴套是用铜或铸铁制成，装配时应细心，可用木锤或锤子垫木块击打的方法装配，过盈尺寸公差较大时则用压力机压入。无论敲入或压入都必须防止倾斜，装配后，油槽和油孔应处在所要求的位置。
Integral sliding bearing commonly known as the shaft sleeve, a kind of form is also the most simple of the sliding bearing, mainly adopt the method of pressure into and hammer to assembly, special occasions with hot pack, most of the collar is made of copper or iron, should be careful when assembling, use wooden hammer or hammer cushion block and the method of assembly and interference with press pressure into the larger size tolerance. The slant and the oil hole should be in the required position, no matter whether the tapping or pressure must be prevented.
