選擇不當(dāng)?shù)闹饕蚴鞘褂脹]有保持架的圓柱滾子軸承代替推力軸承或軸承支承結(jié)構(gòu),。當(dāng)軸向載荷較大時(shí)，能夠承受較大直徑和組合的軸向載荷。經(jīng)過3000小時(shí)的累計(jì)工作,，進(jìn)口軸承的滾動(dòng)表面沒有疲勞損傷，只有劃痕,。軸承在徑向載荷下的疲勞壽命很長,。

The main reason for improper selection is the use of cylindrical roller bearings without cages instead of thrust bearings or bearing support structures. When the axial load is large, it can withstand the axial load of larger diameter and combination. After 3000 hours of cumulative work, the rolling su-ce of imported bearings has no fatigue damage, only scratches. The fatigue life of bearings under radial load is very long.

結(jié)果表明，當(dāng)軸承斷裂時(shí),，材料組織細(xì)小,，不產(chǎn)生粗大的晶粒。斷裂為銀灰色,，屬于脆性斷裂,。

The results show that when the bearing is broken, the structure of the material is fine and no coarse grains are produced. The fracture is silver gray and belongs to brittle fracture.

通常，泰州SKF軸承可以安裝的空間是有限的,。在大多數(shù)情況下,，軸直徑（或軸承內(nèi)徑）是基于機(jī)械設(shè)計(jì)或其*他設(shè)計(jì)限*制。因此,，軸承類型和尺寸的選擇取決于軸承的內(nèi)徑,。為此，根據(jù)國際標(biāo)準(zhǔn)內(nèi)徑尺寸編制了標(biāo)準(zhǔn)軸承的主要尺寸表。

Usually, Taizhou SKF bearings can be installed in limited space. In most cases, the shaft diameter (or bearing inner diameter) is based on mechanical design or other design limitations. Therefore, the choice of bearing type and size depends on the inner diameter of the bearing. For this reason, the main dimension tables of standard bearings are compiled according to the international standard inner diameter dimensions.

根據(jù)軸承的分類,，分析了進(jìn)口泰州SKF軸承的可能產(chǎn)業(yè),。關(guān)鍵問題是根據(jù)公司股票的實(shí)際情況確定重*點(diǎn)行業(yè)。

According to the classification of bearings, the possible industries of SKF bearings imported from Taizhou were analyzed. The key problem is to determine the key industries according to the actual situation of the company's stock.

軸承安裝必*須在干燥,、清潔的環(huán)境中進(jìn)行,。安裝前，應(yīng)仔細(xì)檢查車軸殼安裝面,、肩端面,、槽和連接面的質(zhì)量。

Bearing installation must be carried out in a dry and clean environment. Before installation, the quality of axle housing installation su-ce, shoulder end su-ce, groove and connection su-ce should be carefully checked.

軸承通常用于高速,、高精度的設(shè)備中,，因?yàn)樗ＷC了正常速度和高精度，并且降低了維護(hù)成本,。

Bearings are usually used in high-speed, high-precision equipment, because it guarantees normal speed and high accuracy, and reduces maintenance costs.

通常,，軸在徑向和軸向由兩個(gè)泰州SKF軸承支撐。一側(cè)的軸承稱為固定端軸承,。它同時(shí)承受徑向和軸向載荷,，并作為固定軸和軸承箱之間的相對軸向位移。另一側(cè)稱為自*由端,，只承受徑向載荷,，可以沿軸線相對運(yùn)動(dòng)。

Usually, the shaft is supported by two Taizhou SKF bearings in both radial and axial directions. Bearings on one side are called fixed end bearings. It bears both radial and axial loads and acts as the relative axial displacement between the fixed shaft and the bearing box. The other side, known as the self * free end, bears only radial loads and can move relative along the axis.

雙向推力球軸承運(yùn)行中的檢測項(xiàng)目及損壞原因

Inspection items and damage reasons of bi-directional thrust ball bearings in operation

當(dāng)雙向推力球泰州SKF軸承損壞后拆卸檢查時(shí),，可根據(jù)軸承的損壞情況判斷故障及損壞原因,。

When the two-way thrust ball Taizhou SKF bearing is disassembled and inspected after being damaged, the fault and the cause of the damage can be judged according to the damage of the bearing.

燒壞的軸承在滾道和滾子上回火。燒*傷通常由潤滑不足,、潤滑劑質(zhì)量差或劣化以及軸承的緊密裝配引起,。

Burned bearings are tempered on raceways and rollers. Burns are usually caused by insufficient lubrication, poor or deteriorated lubricant quality, and tight assembly of bearings.

內(nèi)外圈軸承的滾子表面和滾道承受周期性波動(dòng)載荷，導(dǎo)致接觸應(yīng)力的周期性變化,。當(dāng)應(yīng)力循環(huán)次數(shù)達(dá)到一定值時(shí),，疲勞剝落將發(fā)生在滾動(dòng)體的工作表面或內(nèi)外滾道上。如果軸承負(fù)荷過大,，疲勞就會增加,。此外，軸承安裝不當(dāng)和軸彎曲也會導(dǎo)致滾道剝落,。軸承滾道的疲勞剝落會降低軸的工作精度,，引起機(jī)構(gòu)的振動(dòng)和噪聲。

The roller su-ce and raceway of inner and outer ring bearing bear periodic fluctuating load, which results in periodic change of contact stress. When the number of stress cycles reaches a certain value, fatigue spalling will occur on the working su-ce of the rolling element or on the inner and outer raceways. If the bearing load is too large, fatigue will increase. In addition, improper bearing installation and shaft bending can also lead to raceway spalling. Fatigue spalling of bearing raceway will reduce the working accuracy of shaft and cause vibration and noise of mechanism.
