事实上，主轴徐州INA轴承的性能要求和**高要求使得机床具有相同或稍高的寿命。**小寿命比是主轴维修周期的一部分，满足主轴系统的要求不会导致主轴系统过大、经济且成本效益高。奥斯特的机器选项，一个先例已经非常成功可供参考。

In fact, the performance requirements and ** high requirements of Xuzhou INA bearing make the machine tool have the same or slightly higher life. ** Small life ratio is a part of the maintenance cycle of the spindle. Satisfying the requirements of the spindle system will not lead to the spindle system being too large, economical and cost-effective. Oster's machine options, a precedent has been very successful for reference.

在选择和计算时，还应考虑轴承失效形式、磨损形式、润滑失效形式和微磨损形式。**须检查磨损寿命并考虑其余失效模式。

When choosing and calculating, bearing failure form, wear form, lubrication failure form and micro-wear form should also be considered. ** Wear life shall be checked and other failure modes shall be considered.

应当指出，徐州INA轴承的疲劳寿命不仅与润滑和磨损寿命有关，而且直接关系到轴承部件、轴承和润滑剂的安装。这与三个部件的清洁度和密封形式的选择对额定寿命的影响有关。**须提供润滑、清洁和密封条件。这些条件的改*善可以提高轴承的实际寿命。

It should be pointed out that the fatigue life of Xuzhou INA bearings is not only related to lubrication and wear life, but also directly related to the installation of bearing components, bearings and lubricants. This is related to the influence of cleanliness of the three components and the choice of sealing form on the rated life. ** Lubrication, cleaning and sealing conditions shall be provided. The improvement of these conditions can improve the actual life of bearings.

考虑到负载因素，应指出轴承的载荷寿命比转速快，因此多级传动轴串联*大减速时应尽可能敏锐。如果可能的话，主轴轴承应该适当地配备有超支点之间距离的函数。外圈轴承，力求降低L向主轴轴承的负荷，找到主轴徐州INA轴承的传动装置。为了避免在固定载荷下的冲击和振动，**须安装形状和位置精度高、轴承间隙好、轴承安装精度正确的轴承零件。

Considering the load factor, it should be pointed out that the load life of the bearing is faster than the speed, so the multi-stage transmission shafts should be as sensitive as possible when they are connected in series with large deceleration. If possible, spindle bearings should be properly equipped with a function of the distance between the overfulcrums. Outer ring bearing, strive to reduce the L-direction spindle bearing load, find the spindle Xuzhou INA bearing transmission device. In order to avoid imPACt and vibration under fixed loads, ** bearing parts with high accuracy of shape and position, good bearing clearance and correct bearing installation accuracy should be instalLED.

计算负荷的选择和设计能够更准确地反映实际工作负荷，因此对实际负荷进行了广泛深入的研究。

The choice and design of calculation load can more accurately reflect the actual workload, so the actual load has been studied extensively and deeply.

如果施加大量的载荷，但仍不能旋转，这种状态是相对负的，并且滚动体与滚道之间会形成并迅速发展成小点蚀，因此在徐州INA轴承失效的早期阶段压痕。在这种情况下，我们**须验证所选轴承的静态承载能力是否与等效静态载荷进行比较。

If a large amount of load is applied, but still can not rotate, this state is relatively negative, and between the rolling body and the raceway will form and rapidly develop into small pitting corrosion, so in the early stage of Xuzhou INA bearing failure indentation. In this case, we shall verify whether the static bearing capacity of the selected bearing is compared with the equivalent static load.

相反，在另一种极限情况下，轴承高速运转，但不能承受载荷，因此它们经常在滚动滚道中滑动，导致轴承温度急剧上升、润滑剂劣化、轴承失效，因此徐州INA轴承需要**小载荷来防止打滑。

On the contrary, in another extreme case, bearings run at high speed, but can not bear load, so they often slide in the rolling raceway, resulting in a sharp rise in bearing temperature, deterioration of lubricant, bearing failure, so Xuzhou INA bearings need ** small load to prevent slipping.
