在SKF軸承安裝中，各工程師關(guān)心的就是如何正確操作了，如果操作不當(dāng)很可能會造成SKF軸承的損傷。如在高速條件下運(yùn)轉(zhuǎn)，而且工作溫度較高，應(yīng)特別注意旋轉(zhuǎn)套圈的配合不可過松，以防止出現(xiàn)偏心振動，以及固定套圈的配合不可出現(xiàn)間隙，以防止套圈在負(fù)荷下變形并激發(fā)振動。
In the installation of SKF bearings, the engineers are most concerned about how to operate correctly, if not properly, it is likely to cause damage to SKF bearings. If the ring runs at high speed and the working temperature is high, special attention should be paid to the matching of the rotating ring, so as to prevent eccentric vibration, and the matching of the fixed ring can not appear clearance, so as to prevent the ring from deformation and vibration under load.
旋轉(zhuǎn)套圈灼過盈量在可能范圍內(nèi)也宜取得較小。只要切實(shí)保證工作溫度下的熱膨脹影響，以及高轉(zhuǎn)速下的離心力影響，才不致造成緊配合表面的蠕動或滑動。固定套圈根據(jù)工作載荷大小和SKF軸承尺寸，選取極小的間隙配合或過盈配合，過松或過緊都不利于保持原來精確的形狀。
It is also possible to achieve a smaller amount of interference within the range of possible rotation rings. As long as the thermal expansion effect at working temperature and the centrifugal force effect at the highest rotating speed are ensured, the creeping or sliding of the tightly matched surface will not be caused. Fixed ring according to the size of the working load and SKF bearing size, select a minimum clearance fit or interference fit, too loose or too tight is not conducive to maintaining the original accurate shape.
既要精確計(jì)算旋轉(zhuǎn)套圈配合的過盈量，也要精確計(jì)算固定套圈的合適配合量。
It is necessary to accurately calculate not only the interference of rotating ring, but also the fit of fixed ring.
軸與座孔的圓度以及擋肩的垂直度要按照SKF軸承的相應(yīng)精度來要求。
The roundness of the shaft and the hole and the perpendicularity of the shoulder should be in accordance with the corresponding accuracy of the SKF bearing.
保持架組裝精度靠專用組裝胎具保證，完全可以保證SKF軸承的組裝精度要求。
The assembling precision of cage is guaranteed by special assembling fixture, which can completely guarantee the assembling precision requirement of SKF bearing.
對固定圈采取小過盈配合的條件是相配表面雙方都有很高形狀精度和較小的粗糙度，否則造成安裝困難而拆卸更難，此外，還需要考慮主軸熱伸長的影響。
The condition of small interference fit for the fixed ring is that both sides of the matching surface have high shape precision and small roughness, otherwise it will be difficult to install and disassemble. In addition, the influence of spindle thermal elongation should be considered.
擺動載荷和不定載荷在配合上應(yīng)與旋轉(zhuǎn)載荷同等看待，過松的配合會導(dǎo)致配合面損壞。
The swing load and indeterminate load should be treated as the rotating load on the matching. The loose matching will lead to the damage of the matching surface.
相對于載荷方向旋轉(zhuǎn)的套圈與軸或座孔，應(yīng)選擇過渡配合或過盈配合。過盈大小以SKF軸承在載荷下工作時(shí)，其套圈在軸上或座孔內(nèi)的配合表面上不產(chǎn)生“蠕動”現(xiàn)象為原則。而在載荷很輕，或在重載荷作用下套圈偶有低速轉(zhuǎn)動時(shí)，可選用過渡配合，此時(shí)軸表面應(yīng)有較高的硬度和較小的表面粗糙度。
Transitional fit or interference fit should be chosen for the ring and shaft or seat hole relative to the load direction. The interference size is based on the principle that when SKF bearing works under load, the ring does not creep on the mating surface of shaft or seat hole. When the load is very light, or when the ring is occasionally rotated at low speed under heavy load, the transition fit can be chosen. At this time, the shaft surface should have higher hardness and smaller surface roughness.
對于重載荷場合，通常應(yīng)比在輕載荷和正常載荷場合的配合為緊。載荷愈重，其配合過盈應(yīng)愈大。
For heavy load occasions, it should be more compact than the light load and normal load occasions. The heavier the load is, the greater the interference should be.
使用成對雙聯(lián)角接觸球軸承的主軸，多半載荷較輕，其配合過盈量如偏大，則其內(nèi)部的軸向預(yù)緊量將顯著偏大，造成不利影響。使用雙列短圓柱滾子軸承的主軸以及圓錐滾子軸承的主軸，其載荷相對較大，所以其配合過盈也相對較大。
Most of the spindles with paired angular contact ball bearings have light loads. If the fit interference is too large, the axial preload inside the spindles will be significantly larger, resulting in adverse effects. The spindle with double row short cylindrical roller bearings and the spindle with tapered roller bearings have relatively large load, so their fit interference is relatively large.
有時(shí)載荷的方向和大小無法確切地判定，例如在高速旋轉(zhuǎn)機(jī)械中，除所承受轉(zhuǎn)子重量為方向固定的載荷而外，還有不平衡質(zhì)量所引起的旋轉(zhuǎn)載荷，如果這種旋轉(zhuǎn)載荷比固定載荷大得多，則其合成載荷仍為旋轉(zhuǎn)載荷；而如果旋轉(zhuǎn)載荷比固定載荷小得多，則合成載荷為擺動載荷。不論旋轉(zhuǎn)載荷還是擺動載荷， SKF軸承其大小和方向都在不斷變化。而在可變工作狀態(tài)下，有的套圈所受載荷可能時(shí)而是旋轉(zhuǎn)載荷，時(shí)而是固定載荷，又時(shí)而是擺動載荷。這種載荷稱為不定載荷。
Sometimes the direction and magnitude of the load can not be determined precisely, for example, in high-speed rotating machinery, there are rotational loads caused by unbalanced mass besides the loads on which the rotor weight is fixed in the direction. If the rotational loads are much larger than the fixed loads, the composite loads are still rotational loads; and if the rotational loads are still rotational loads. The load is much smaller than the fixed load, and the composite load is the swing load. Regardless of rotary load or swing load, the size and direction of SKF bearings are constantly changing. In the case of variable working conditions, some rings may be subjected to rotating loads, sometimes fixed loads, and sometimes swing loads. This load is called an indefinite load.
