南京SKF轴承高轴向精细尺度的衡量

由于轴承本身的精度小于1微米，因此将轴承的精度控制在与轴承的精度相同的水平内是非常重要和容易被忽略的。

Because the accuracy of the bearing itself is less than 1 micron, it is very important and easy to be ignored to control the accuracy of the bearing within the same level as the accuracy of the bearing.

应注意的是，如果一般南京SKF轴承的附件不能满足上述要求，往往使轴承的安装误差比原来的轴承误差多几倍，甚至超过10倍，都是不轴承，其原因是普遍的。交流轴承RoR的停顿通常不是简单地叠加在轴承误差上，而是不同的乘法器。扩大和增加。

It should be noted that if the accessories of Nanjing SKF bearings can not meet the above requirements, often make the installation error of bearings than the original bearing error several times, or even more than 10 times, are not bearings, the reason is common. The pause of AC bearing RoR is usually not simply superimposed on bearing error, but different multiplier. Expand and increase.

南京SKF轴承的传统应用领域是机床主轴。根据不同的加工程序，机床主轴有不同的要求。车床主轴通常用于切削金属，切削速度较低，切削载荷较大。这种类型的主轴通常通过皮带轮或齿轮驱动扭矩。这意味着主轴驱动端上的负载相当大。

The traditional application field of SKF bearings in Nanjing is the spindle of machine tools. According to different machining procedures, machine tool spindles h***e different requirements. The spindle of lathe is usually used for cutting metal, with lower cutting speed and larger cutting load. This type of spindle usually drives torque through a belt pulley or gear. This means that the load on the spindle drive end is quite large.

这样的应用不需要太多的速度，更重要的参数是刚度和承载能力。一种常见的方法是在主轴的操作端安装一排圆柱滚子轴承和对角接触推力球轴承，并使用南京SKF轴承一对圆柱滚子轴承和主轴的驱动端。该设备可确保长寿命和优良的刚性，然后生产高质量的工件。

Such applicati*** do not require much speed, and more important parameters are stiffness and bearing capacity. A common method is to install a row of cylindrical roller bearings and diagonal contact thrust ball bearings at the operating end of the spindle, and to use a pair of Nanjing SKF bearings on the cylindrical roller bearings and the driving end of the spindle. The equipment can ensure long life and excellent rigidity, and then produce high quality workpieces.

对于具有高轴向刚度的应用，优选具有大接触角的角接触推力球轴承。它的刚度随着预压的增加而增加，但这制约了它的允许速度。

For applicati*** with high axial stiffness, angular contact thrust ball bearings with large contact angles are preferred. Its stiffness increases with the increase of preloading, but this restricts its allowable speed.

由于空间制约和对刚度和旋转精度的高要求，南京SKF轴承通常需要高精度的应用。小截面轴承可以容纳相对较大的直径轴，并在相对较小的轴承形状中获得所需的高刚度。

Due to space c***traints and high requirements for stiffness and rotation accuracy, Nanjing SKF bearings usually require high precision applicati***. ***all section bearings can accommodate relatively large diameter shafts and obtain the required high stiffness in relatively ***all bearing shapes.

机床常用的角接触球轴承、圆柱滚子轴承和角接触推力球轴承是简单的ISO9和0直径系列。2直径系列角接触球轴承在新的设计中很少使用，但在现有的应用中仍然很普遍。通过选择9个或0个系列轴承，可以在相同的径向空间中实现特定目的的更好轴承配置。

Angular contact ball bearings, cylindrical roller bearings and angular contact thrust ball bearings commonly used in machine tools are simple ISO9 and 0 diameter series. 2-Diameter series angular contact ball bearings are rarely used in new designs, but are still common in existing applicati***. By selecting nine or zero series bearings, better bearing configurati*** can be achieved for specific purposes in the same radial space.

由于空间约束不是主要问题，螺旋接触球轴承可以具有大的横截面。对于这些南京SKF轴承，类似的2或3直径系列是常见的。除了轴承的其余一般要求外，承载能力也是非常重要的。

Because the space c***traint is not the main problem, the spiral contact ball bearing can h***e a large cross section. For these Nanjing SKF bearings, a similar 2 or 3 diameter series is common. In addition to the rest of the general requirements of bearing, bearing capacity is also very important.
