建议将泰州SKF轴承旋转环的点火干扰降低到较小的程度。只要在工作温度下保证热膨胀效应和**大离心力，紧密匹配的表面就不会蠕变或滑动。固定环根据工作负荷和轴承尺寸选择**小间隙配合或过盈配合。太松或太紧不利于保持原有精*确的形状。
It is suggested that the ignition interference of SKF bearing rotating ring in Taizhou should be reduced to a lesser extent. As long as the thermal expansion effect and ** large centrifugal force are guaranteed at working temperature, the tightly matched surfaces will not creep or slip. Fixed rings are selected with ** ***all clearance fit or interference fit according to workload and bearing size. Too loose or too tight is not conducive to maintaining the original precise shape.
旋转环配合和固定环配合的干涉计算需要精*确。
The interference calculation of rotating ring fit and fixed ring fit needs to be precise and accurate.
根据泰州SKF轴承的相应精度，要求轴和座孔的圆度和肩部的垂直度。
According to the corresponding accuracy of Taizhou SKF bearing, the roundness of shaft and seat hole and the verticality of shoulder are required.
采用特殊的装配工具，确保保持架和轴承的装配精度。
Special assembly tools are used to ensure the assembly accuracy of cages and bearings.
固定环小过盈配合的条件是匹配面两侧的形状精度高，粗糙度小。否则，安装和拆卸将变得更加困难。此外，还应考虑主轴热伸长的影响。
The condition of ***all interference fit of fixed ring is that the shape accuracy of both sides of the matching surface is high and the roughness is ***all. Otherwise, installation and disassembly will become more difficult. In addition, the influence of thermal elongation of spindle should also be c***idered.
在匹配时，应将摆动载荷和不确定载荷视为与旋转载荷相同。松动匹配会损坏匹配表面。
When matching, the swing load and the uncertain load should be regarded as the same as the rotating load. Loose matching can damage the matching surface.
对于沿载荷方向旋转的环和轴或座孔，应选择过渡配合或过盈配合。这种干涉是基于轴承在负载下工作时，在泰州SKF轴承轴或座孔中的环的配合表面上不存在“蠕变”现象的原理。当负载很轻或者当环在重负载下偶尔以低速旋转时，可以选择过渡配合。此时，轴表面应具有较高的硬度和较小的表面粗糙度。
Transition fit or interference fit should be selected for rings and axes or seat holes rotating along load direction. This interference is based on the principle that there is no "creep" phenomenon on the mating surface of the ring in the shaft or seat hole of SKF bearing in Taizhou when the bearing works under load. Transition fit can be selected when the load is very light or when the ring occasionally rotates at a low speed under he***y load. At this time, the shaft surface should h***e higher hardness and ***aller surface roughness.
采用斜接触球轴承主轴时，大部分载荷较小。如果配合过盈量大，内部轴向预紧力将显著增加，从而产生不利影响。双列短圆柱滚子轴承和圆锥滚子轴承具有较大的主轴载荷和较大的匹配干涉。
When using oblique contact ball bearing spindle, most of the load is ***all. If the fit interference is large, the internal axial pre-tightening force will increase significantly, which will h***e adverse effects. Double row short cylindrical roller bearings and tapered roller bearings h***e larger spindle load and larger matching interference.
有时不能准确地确定泰州SKF轴承负载的方向和大小。例如，在高速旋转机械中，除了转子重量固定的负载外，还存在由质量不平衡引起的旋转负载。如果旋转载荷远大于固定载荷，则复合载荷仍将是旋转载荷；如果旋转载荷大于固定载荷，则复合载荷仍将是旋转载荷。如果载荷远小于固定载荷，则复合载荷是摆动载荷。无论是旋转载荷还是摆动载荷，轴承的尺寸和方向都在不断地变化。在不同的工作条件下，一些环可能受到旋转、固定和摆动载荷。这种荷载称为不定荷载。
Sometimes, the direction and size of SKF bearing load in Taizhou can not be accurately determined. For example, in high-speed rotating machinery, besides the load with fixed rotor weight, there are also rotating loads caused by mass imbalance. If the rotating load is much larger than the fixed load, the composite load will still be the rotating load; if the rotating load is larger than the fixed load, the composite load will still be the rotating load. If the load is much less than the fixed load, the composite load is the swing load. Whether rotating load or swing load, bearing size and direction are c***tantly changing. Under different working conditi***, some rings may be subjected to rotating, fixed and swing loads. This kind of load is called indefinite load.
