根据摩擦的性质，轴承可分为滑动摩擦轴承和滚动摩擦轴承。滑动轴承主要用于高速、高支承要求、过载、冲击、fen裂的工作环境中。
According to the nature of friction, bearings can be divided into sliding friction bearings and rolling friction bearings. Sliding bearings are mainly used in high speed, high support requirements, overload, impact, Fen crack working environment.
滚动淮安SKF轴承通常由外圈、内圈、滚动体和保持架组成。内圈安装在轴颈上，外圈安装在轴承座孔内。在大多数情况下，内环沿轴旋转，而外环保持静止。工作时，滚筒在内外环之间滚动，保持架将滚筒均匀分开，从而减少了滚筒之间的摩擦和磨损。
Rolling Huaian SKF bearings are usually composed of outer ring, inner ring, rolling element and cage. The inner ring is mounted on the journal and the outer ring is mounted in the bearing seat hole. In most cases, the inner ring rotates along the axis while the outer ring remains stationary. When working, the drum rolls between the inner and outer rings, and the cage divides the drum evenly, thus reducing friction and wear between the drums.
平面推力球轴承在使用过程中主要承受轴向载荷，因而的到了广泛的应用。平面推力球轴承虽然安装方法相对简单，但在实际的维修操作中经常出现问题。***常见的是轴承环安装是否正确。
Planar thrust ball bearings are mainly subjected to axial loads in the use process, so they are widely used. Although the installation method of planar thrust ball bearings is relatively simple, problems often occur in the actual maintenance operation. *** is often the correct installation of bearing rings.
因此，轴承很快就会损坏。当紧环内环向淮安SKF轴承轴颈过渡时，紧环由轴承的转动时间驱动，轴承横截面与静止部件之间产生摩擦。摩擦力将大于内径匹配的阻力矩，导致紧环与轴承配合面强制转动。
Therefore, the bearing will be damaged soon. When the inner ring of the tightening ring transits to the Journal of Huaian SKF bearing, the tightening ring is driven by the rotation time of the bearing, and friction occurs between the cross section of the bearing and the stationary parts. Friction force will be greater than the resistance moment of inner diameter matching, resulting in the forced rotation of the tightening ring and bearing mating surface.
为了安装平面推力轴承，应注意以下三点。首先，bi须区分平面推力球轴承的紧环和松环与机构的静环。在任何情况下，轴承的松动环都适度地位于固定零件的端面上。
In order to install the plane thrust bearing, the following three points should be paid attention to. Firstly, the Bi must distinguish the tight ring and the loose ring of the plane thrust ball bearing from the static ring of the mechani***. In any case, the loosening ring of the bearing is moderately located on the end face of the fixed part.
为了保证轴承的承载能力和工作性能与环形轴承相同，轴或壳孔的硬度滚动到表面，加工精度和表面质量应与环形淮安SKF轴承相同，轴或壳孔的表面应与T相同。T形内孔。洞。D外孔。掘进机滚动面。
In order to ensure that the bearing capacity and working performance are the same as the ring bearing, the hardness of the shaft or shell hole rolls to the surface, the processing accuracy and surface quality should be the same as that of the ring Huaian SKF bearing, and the surface of the shaft or shell hole should be the same as that of T. T-shaped inner hole. Hole. D outer hole. Rolling surface of roadheader.
该轴承结构紧凑，体积小，转动精度高，能承受较高的径向载荷和一定的轴向载荷。
The bearing has compact structure, ***all size, high rotation accuracy, and can withstand higher radial load and certain axial load.
调心滚子轴承是在两个滚道的内圈和球面滚道的外圈之间装配有鼓形滚子的轴承。调心球轴承由两个滚道的内环和球面滚道的外环组成。调心滚子淮安SKF轴承有两排滚子。带有球面外圈和内圈的普通滚道沿轴承轴倾斜。外滚道中球体的中xin点是轴承的轴。
Self-aligning roller bearings are bearings with drum-shaped rollers assembled between the inner rings of two raceways and the outer rings of spherical raceways. The self-aligning ball bearing is composed of inner ring of two raceways and outer ring of spherical raceway. The aligning roller Huaian SKF bearing has two rows of rollers. The common raceway with spherical outer ring and inner ring inclines along the bearing shaft. The Central Xin point of the sphere in the outer raceway is the axis of the bearing.

调心滚子轴承的滚子公差：
Roller tolerances of self-aligning roller bearings:
球面滚子轴承的滚子采用非常严格的公差尺寸和形状制造。各辊组其余辊的尺寸和形状基本相同，***大限度地延长了辊淮安SKF轴承的使用寿命，优化了负荷分配。
Rollers of spherical roller bearings are manufactured in very strict tolerance sizes and shapes. The dimensi*** and shapes of the other rollers in each roll group are basically the same. *** greatly prolongs the service life of SKF bearings in Roll Huai'an and optimizes the load distribution.
