| 角接触球轴承的特点 Characteristics of angular contact ball bearing 可同时承受径向负荷和轴向负荷，转速较高，接触角越大，轴向承载能力越高。 It can bear radial load and axial load at the same time. The higher the rotating speed, the larger the contact angle, the higher the axial bearing capacity. 单列轴承只能承受一个方向的轴向负荷，在承受径向负荷时，将引起附加轴向力。并且只能限制轴或外壳在一个方向的轴向位移。若是成对双联安装，使一对轴承的外圈相对，即宽端面对宽端面，窄端面对窄端面。这样即可避免引起附加轴向力，而且可在两个方向使轴或外壳限制在轴向游隙范围内。角接触球轴承的变型结构多达70多种。 Single row bearing can only bear axial load in one direction. When bearing radial load, it will cause additional axial force. And only limit the axial displacement of the shaft or shell in one direction. If it is installed in pairs, make the outer rings of a pair of bearings opposite, that is, wide end face to wide end face, and narrow end face to narrow end face. In this way, the additional axial force can be avoided, and the shaft or shell can be limited to the axial clearance range in two directions. There are more than 70 kinds of variable structure of angular contact ball bearing. 名义接触角有15°、 25°、 40°三种，接触角越大轴向承载能力越高。高精度和高速轴承通常取15°接触角，在轴向力作用下，接触角会增大。一般为内圈或外圈带锁口，内、外圈不可分离。外圈加热膨胀后与内圈、滚动体、 保持架组件装配。装球数比深沟球轴承多，额定负荷在球轴承中最大，刚性强，运转平稳。可以利用内、外圈相互位移调整径向游隙。常成对使用，并施加预负荷，以提高轴承刚性。 There are three kinds of nominal contact angles: 15 °, 25 ° and 40 °. The larger the contact angle is, the higher the axial bearing capacity is. The contact angle of high-precision and high-speed bearings is usually 15 °. Under the action of axial force, the contact angle will increase. Generally, the inner ring or outer ring is provided with a lock, and the inner and outer rings cannot be separated. After the outer ring is heated and expanded, it is assembled with the inner ring, rolling body and cage assembly. The number of balls installed is more than that of deep groove ball bearing, and the rated load is the largest in the ball bearing, with strong rigidity and stable operation. The internal and external displacements can be used to adjust the radial clearance. It is often used in pairs and preloaded to improve the bearing rigidity. |
