双向推力球徐州SKF轴承损坏后解体检查时，可根据轴承损坏情况判断故障及损坏原因。

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。滚道表面金属剥落

1. metal spalling on raceway su-ce

轴承滚动体和内外环滚道表面承受周期性波动载荷，导致接触应力周期性变化。当应力循环次数达到一定值时，滚动表面或内外滚道均会发生疲劳剥落。如果轴承负荷过大，会加剧疲劳。此外，轴承安装不当和轴弯曲也可能导致滚道剥落。轴承滚道疲劳剥落会降低轴的工作精度，引起机构振动和噪声。

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。轴承

2. Bearing

温高损伤的轴承滚道和滚子有回火的颜色。徐州SKF轴承温高损伤通常由润滑不足、润滑剂质量差或劣化以及轴承的紧密装配引起。

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。塑性变形

Three. Plastic deformation

滚道与轴承滚子接触面上的凹坑表明轴承存在塑性变形。其原因是轴承工作表面的局部应力超出了材料在大的静载荷或冲击载荷下的屈服极限，这通常发生在低速轴承中。

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。轴承环裂纹

4. Bearing Ring Crack

徐州SKF轴承座圈裂纹产生的原因有轴承配合过紧、内外圈松动、轴承套变形、轴承安装面加工不顺畅等。

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。罐笼破碎*机

5. Cage crusher

原因包括润滑不足、滚动部件损坏和座圈倾斜。

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

6。保持架的金属与滚动元件相连。

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

可能的原因是，滚动元件卡在保持架中或没有足够的润滑。

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

7。环磨损严重

7. Ring wear is serious

可能是异物掉入座圈，润滑油不足或润滑油牌号不当。

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

影响双向推力球徐州SKF轴承损坏的主要因素有载荷、润滑、装配、环境条件、材料质量或制造精度等。

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.
