角接触球轴承 ANGULAR CONTACT BALLBEARING

角接触轴承的特点是它既能承受径向载荷又能承受单方向轴向载荷。接触角越大，承受轴向载荷越大，接触角越小，承受轴向载荷就越小。反之，接触角越小，承受径向载荷的能力越大，也越适用于高速应用的场合。根据不同工况条件，它可以有多种组配方式以获得不同的承受径向和轴向载荷能力，并满足高转速和径、轴向高刚度的要求。

角接触球轴承精度等级包括尺寸公差和旋转精度。精度由低到高表示为PO(普通)、P6(P6X)、P5、P4、P2，此外，欧美品牌中也用P3、P7、P9表示精度等级，P3相当于ISO和JIS标准的P6级，P7相当于P4级，P9相当于P2级。

Angular contact ball bearings can bear both radial loads and unidirectional axial loads. A larger contact angle enables the bearing to withstand a greater axial load, while a smaller contact angle results in lower axial-load capacity. Conversely, a smaller contact angle delivers higher radial-load capacity and makes the bearing more suitable for high-speed operating conditions. According to different working conditions, various mounting configurations are available to achieve different radial and axial load-bearing capacities, meeting the requirements of high rotational speed as well as high radial and axial rigidity.

The precision grades of angular contact ball bearings cover dimensional tolerances and running accuracy. Precision levels from low to high are designated as P0 (Normal), P6 (P6X), P5, P4 and P2. In addition, European and American brands also adopt P3, P7 and P9 for precision grading: P3 is equivalent to ISO / JIS P6 grade, P7 corresponds to P4 grade, and P9 is equivalent to P2 grade.

安装形式 Mounting Types

角接触球轴承的安装形式有背对背、面对面和串联排列三种。

背对背（两轴承的宽端面相对）安装时，轴承的接触角线沿回转轴线方向扩散，可增加其径向和轴向的支承角度刚性，抗变形能力最大；

面对面（两轴承的窄端面相对）安装时，轴承的接触角线朝回转轴线方向收敛，其支承角度刚性较小。由于轴承的内圈伸出外圈，当两轴承的外圈压紧到一起时，外圈的原始间隙消除，可以增加轴承的预加载荷;

串联排列（两轴承的宽端面在一个方向）安装时，轴承的接触角线同向且平行，可使两轴承分担同一方向的工作载荷。但使用这种安装形式时，为了保证安装的轴向稳定性，两对串联排列的轴承必须在轴的两端对置安装。

Angular contact ball bearings have three mounting types: back-to-back, face-to-face and tandem arrangement In the back-to-back mounting (the wide faces of the two bearings face each other), the lines of contact angle diverge along the rotational axis, which improves the radial and axial support rigidity and delivers the highest deformation resistance.

In the face-to-face mounting (the narrow faces of the two bearings face each other), the lines of contact angle converge toward the rotational axis, resulting in lower support rigidity. Since the inner ring extends beyond the outer ring, the original clearance of the outer rings is eliminated when the outer rings of the two bearings are clamped together, which increases the preload of the bearings.

In the tandem arrangement (the wide faces of both bearings point in the same direction), the lines of contact angle are parallel and oriented identically. The two bearings share the working load in a single direction. For this mounting configuration, two sets of tandem-arranged bearings must be mounted opposite each other at both ends of the shaft to ensure axial stability.

四点角接触球轴承

Four Point

Angular Contact Ball Bearing

四点接触球轴承是一种分离型轴承，也可以说是一种轴承可承受双向轴向载荷的角接触球轴承，其内、外圈滚道是桃型的截面，当无载荷或是纯径向载荷作用时，钢球和套圈呈现为四点接触，这也是这个名称的由来。

若轴承内、外圈之间存在倾斜的角，将影响轴承的寿命，同时造成轴承运转精度下降，运转噪声增大。双列角接触球轴承一般采用尼龙保持架或黄铜实体侯持架。
