雙向推力球徐州SKF軸承損壞后解體檢查時(shí),，可根據(jù)軸承損壞情況判斷故障及損壞原因,。

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

1,。滾道表面金屬剝落

1. metal spalling on raceway su-ce

軸承滾動體和內(nèi)外環(huán)滾道表面承受周期性波動載荷,，導(dǎo)致接觸應(yīng)力周期性變化。當(dāng)應(yīng)力循環(huán)次數(shù)達(dá)到一定值時(shí),，滾動表面或內(nèi)外滾道均會發(fā)生疲勞剝落,。如果軸承負(fù)荷過大，會加劇疲勞,。此外,，軸承安裝不當(dāng)和軸彎曲也可能導(dǎo)致滾道剝落。軸承滾道疲勞剝落會降低軸的工作精度,，引起機(jī)構(gòu)振動和噪聲,。

The su-ce of bearing rolling element and inner and outer ring raceway bears 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 rolling su-ce or the inner and outer raceways. If the bearing load is too large, it will aggravate fatigue. In addition, improper bearing installation and shaft bending may also lead to raceway spalling. Fatigue peeling of bearing raceway will reduce the working accuracy of shaft and cause vibration and noise of mechanism.

2。軸承

2. Bearing

溫高損傷的軸承滾道和滾子有回火的顏色,。徐州SKF軸承溫高損傷通常由潤滑不足,、潤滑劑質(zhì)量差或劣化以及軸承的緊密裝配引起。

Bearing raceways and rollers with high temperature damage have tempering color. High temperature damage of Xuzhou SKF bearings is usually caused by insufficient lubrication, poor lubricant quality or deterioration, and tight assembly of bearings.

三,。塑性變形

Three. Plastic deformation

滾道與軸承滾子接觸面上的凹坑表明軸承存在塑性變形,。其原因是軸承工作表面的局部應(yīng)力超出了材料在大的靜載荷或沖擊載荷下的屈服極限,，這通常發(fā)生在低速軸承中,。

The pits on the contact su-ce between raceway and bearing roller indicate that the bearing has plastic deformation. The reason is that the local stress on the working su-ce of bearings exceeds the yield limit of materials under large static or impact loads, which usually occurs in low-speed bearings.

4。軸承環(huán)裂紋

4. Bearing Ring Crack

徐州SKF軸承座圈裂紋產(chǎn)生的原因有軸承配合過緊,、內(nèi)外圈松動,、軸承套變形、軸承安裝面加工不順暢等,。

The causes of the cracks in Xuzhou SKF bearing seat ring include too tight bearing matching, loose inner and outer rings, deformation of bearing sleeve, and poor processing of bearing installation su-ce.

5,。罐籠破碎*機(jī)

5. Cage crusher

原因包括潤滑不足、滾動部件損壞和座圈傾斜,。

Causes include insufficient lubrication, damage to rolling parts and inclination of seat rings.

6,。保持架的金屬與滾動元件相連。

6. The metal of the cage is connected to the rolling element.

可能的原因是,，滾動元件卡在保持架中或沒有足夠的潤滑,。

The possible reason is that the rolling element is stuck in the cage or not sufficiently lubricated.

7。環(huán)磨損嚴(yán)重

7. Ring wear is serious

可能是異物掉入座圈,，潤滑油不足或潤滑油牌號不當(dāng),。

It may be that the foreign body falls into the seat ring, the lubricant is insufficient or the lubricant brand is improper.

影響雙向推力球徐州SKF軸承損壞的主要因素有載荷、潤滑,、裝配,、環(huán)境條件、材料質(zhì)量或制造精度等,。

The main factors affecting the damage of Xuzhou SKF bearing with bi-directional thrust ball are load, lubrication, assembly, environmental conditions, material quality or manufacturing accuracy, etc.
