圆锥滚子轴承属于分离型轴承，轴承的内、外圈均具有锥形滚道。该类轴承按所装滚子的列数分为单列、双列和四列圆锥滚子轴承等不同的结构型式。单列圆锥滚子轴承可以承受径向负荷和单一方向轴向负荷。当轴承承受径向负荷时，将会产生一个轴向分力，所以当需要另一个可承受反方向轴向力的轴承来加以平衡。广泛用于汽车、轧机、矿山、冶金、塑料机械等行业。

　　Tapered roller bearings are separable bearings, bearing inner and outer rings have conical raceway. This kind of bearing is divided into single row, double row and four row tapered roller bearings according to the number of rows installed. Single row tapered roller bearings can withstand radial loads and uniaxial axial loads. When bearings are subjected to radial loads, an axial component is produced, so another bearing that can withstand the reverse axial force is needed to balance. Widely used in automobiles, rolling mills, mines, metallurgy, plastics machinery and other industries.

　　轴承特点 Bearing characteristics

　　圆锥滚子轴承的类型代号为30000，圆锥滚子轴承为分离型轴承。一般情况下，尤其是在GB/T307.1-94《滚动轴承 向心轴承公差》中所涉及到的尺寸范围内的圆锥滚子轴承外圈与内组件之间是百分之百可以通用互换使用的。

　　The type of tapered roller bearings is 30000, tapered roller bearings are separable bearings. In general, especially in GB / T307.1-94 "Rolling Bearing Centroid Bearing Tolerance" refers to the size range of tapered roller bearings between the outer ring and the inner assembly is 100% interchangeable.

　　外圈的角度以及外滚道直径尺寸已与外形尺寸相同被标准化规定了。不允许在设计制造时更改。以致使圆锥滚子轴承的外圈与内组件之间可在世界范围内通用互换。

　　The angle of the outer ring and the diameter of the raceway are standardized with the same size. It is not allowed to change during design and manufacture. The outer ring and inner components of the tapered roller bearing can be exchanged all over the world.

　　圆锥滚子轴承主要用于承受以径向载荷为主的径向与轴向联合载荷。与角接触球轴承相比、承载能力大，极限转速低。圆锥滚子轴承能够承受一个方向的轴向载荷，能够限制轴或外壳一个方向的轴向位移。

　　Tapered roller bearings are mainly used to bear radial load combined with radial load. Compared with angular contact ball bearings, the bearing capacity is high and the limit speed is low. Tapered roller bearings can withstand axial loads in one direction and can limit axial displacement in one direction of the shaft or housing.
