（1）从室温到高温的尺度变化和硬度变化。

(1) scale changes and hardness changes from room temperature to high temperature.

（2）镇江NSK轴承高速离心力引起的力变化和形状变化。

(2) force variation and shape change caused by high speed centrifugal force of NSK bearing in Zhenjiang.

为了保证小变形，过盈配合的干涉不能太大，而离心力在高速和高温下会产生热膨胀，或抵消常压配合的外观。或者为了放松合作，有必要在仔细计算的前提下考虑以上两个因素。在室温和速度下的真实干扰对镇江NSK轴承高速载体无效。

In order to ensure ***all deformation, interference of interference fit can not be too large, and centrifugal force at high speed and high temperature will produce thermal expansion, or offset the appearance of atmospheric pressure fit. Or to relax cooperation, it is necessary to c***ider the above two factors on the premise of careful calculation. The real interference at room temperature and speed is not valid for Zhenjiang NSK bearing high-speed carrier.

如果结果太不一致（通常以非常高的速度），结合环平滑和静态平滑的两层平滑方案可能超过300万的阈值。

If the results are too inc***istent (usually at very high speeds), a two-layer ***oothing scheme combining ring ***oothing and static ***oothing may exceed the threshold of 3 million.

在考虑高速间隙时，不仅要考虑上述因素，还要考虑轴的热伸长对间隙的影响。工作条件，即在工作温度下的上好间隙，在内环槽和外环槽内标准对齐。由于相对滑动和高速内部冲突的减少，尽量不要通过内外环的镇江NSK轴承轴向相对不对准来调整间隙。

When c***idering the high-speed clearance, not only the above factors should be c***idered, but also the effect of shaft thermal elongation on the clearance. Working conditi***, that is, the upper clearance at the working temperature, is aligned in the inner ring groove and the outer ring groove. Due to the reduction of relative sliding and internal conflict at high speed, the clearance should not be adjusted by the relative axial misalignment of Zhenjiang NSK bearing with inner and outer rings.

当考虑干涉和间隙时，应当注意，在高温下，材料变得柔软并且容易变形，并且由于反复的温度变化，从室温到高温可能发生不可逆变形。

When c***idering interference and clearance, it should be noted that at high temperatures, the material becomes soft and easily deformed, and irreversible deformation may occur from room temperature to high temperature due to repeated temperature changes.

2。主机相关组件的要求

2. Requirements for host related components

镇江NSK轴承高速轴承需要旋转系统的标准动态平衡。轴和座孔的安装位置应该比以前更标准，特别是对于同轴和垂直度的肩膀、座孔或弹匣。

The NSK bearing high speed bearing in Zhenjiang needs the standard dynamic balance of the rotating system. The mounting position of the shaft and seat holes should be more standard than before, especially for shoulders, seat holes or magazines with coaxial and vertical degrees.

为了克服这种矛盾，如降低表面粗糙度、提高表面硬化措施和空心轴支承刚度，可以降低系统的质量。

In order to overcome this contradiction, such as reducing the surface roughness, improving the surface hardening measures and supporting stiffness of hollow shaft, the quality of the system can be reduced.
