事實(shí)上,，主軸徐州INA軸承的性能要求和**高要求使得機(jī)床具有相同或稍高的壽命,。**小壽命比是主軸維修周期的一部分,，滿足主軸系統(tǒng)的要求不會(huì)導(dǎo)致主軸系統(tǒng)過大,、經(jīng)濟(jì)且成本效益高,。奧斯特的機(jī)器選項(xiàng)，一個(gè)先例已經(jīng)非常成功可供參考,。

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.

在選擇和計(jì)算時(shí),，還應(yīng)考慮軸承失效形式、磨損形式,、潤滑失效形式和微磨損形式,。**須檢查磨損壽命并考慮其余失效模式。

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.

應(yīng)當(dāng)指出,，徐州INA軸承的疲勞壽命不僅與潤滑和磨損壽命有關(guān),，而且直接關(guān)系到軸承部件、軸承和潤滑劑的安裝,。這與三個(gè)部件的清潔度和密封形式的選擇對(duì)額定壽命的影響有關(guān),。**須提供潤滑、清潔和密封條件,。這些條件的改*善可以提高軸承的實(shí)際壽命,。

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.

考慮到負(fù)載因素，應(yīng)指出軸承的載荷壽命比轉(zhuǎn)速快,，因此多級(jí)傳動(dòng)軸串聯(lián)*大減速時(shí)應(yīng)盡可能敏銳,。如果可能的話，主軸軸承應(yīng)該適當(dāng)?shù)嘏鋫溆谐c(diǎn)之間距離的函數(shù),。外圈軸承,，力求降低L向主軸軸承的負(fù)荷，找到主軸徐州INA軸承的傳動(dòng)裝置,。為了避免在固定載荷下的沖擊和振動(dòng),，**須安裝形狀和位置精度高、軸承間隙好,、軸承安裝精度正確的軸承零件,。

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.

計(jì)算負(fù)荷的選擇和設(shè)計(jì)能夠更準(zhǔn)確地反映實(shí)際工作負(fù)荷，因此對(duì)實(shí)際負(fù)荷進(jìn)行了廣泛深入的研究,。

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

如果施加大量的載荷,，但仍不能旋轉(zhuǎn)，這種狀態(tài)是相對(duì)負(fù)的,，并且滾動(dòng)體與滾道之間會(huì)形成并迅速發(fā)展成小點(diǎn)蝕,，因此在徐州INA軸承失效的早期階段壓痕。在這種情況下,，我們**須驗(yàn)證所選軸承的靜態(tài)承載能力是否與等效靜態(tài)載荷進(jìn)行比較,。

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，在另一種極限情況下，軸承高速運(yùn)轉(zhuǎn),，但不能承受載荷,，因此它們經(jīng)常在滾動(dòng)滾道中滑動(dòng)，導(dǎo)致軸承溫度急劇上升,、潤滑劑劣化,、軸承失效，因此徐州INA軸承需要**小載荷來防止打滑,。

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.
