南京SKF轴承61914于发动机中损坏的三大现象

轴承产品在世界轴承市场中具有重要的指导作用。实际南京SKF轴承的质量由强度保证，但也会损坏。同时，由于应用范围的不同，***的特点也不尽相同。其次，对起动机滑动轴承的缺陷、损坏性能及原因进行了分析。

Bearing products play an important guiding role in the world bearing market. The quality of the actual SKF bearing in Nanjing is guaranteed by strength, but it will also be damaged. At the same time, due to the different application scope, the characteristics of destruction are different. Secondly, the defects, damage performance and causes of starter sliding bearing are analyzed.

合金腐蚀

Alloy corrosion

不良的南京SKF轴承油品质量是轴承合金腐蚀的主要原因，而不良的油品质量是***或其他化学杂质***明显的表现。特别是在化学杂质的存在下，合金表面会形成一层酸性物质，从而导致金属剥落、凹痕等现象。

The poor quality of Nanjing SKF bearing oil is the main cause of bearing alloy corrosion, and the poor quality of oil is the most ***ious manifestation of foreign bodies or other chemical impurities. Especially in the presence of chemical impurities, the alloy surface will form a layer of acid material, resulting in metal spalling, dents and other phenomena.

除了南京SKF轴承润滑油的选择不当外，轴承材料的耐腐蚀性、高温、腐蚀性空气接触等因素都会影响轴承合金的腐蚀。

Except for the inappropriate selection of Nanjing SKF bearing lubricant, the corrosion resistance of bearing material, high temperature, corrosive air contact and other factors will affect the corrosion of bearing alloy.

二、机器损坏

Two, machine damage

轴颈南京SKF轴承机械损伤的主要形式是轴承表面的压痕和划痕。当情况严重时，轴承就会脱落。有一件事你需要知道的是，***常常伴随着这一成就而发生。

The main form of mechanical damage of the journal bearing of Nanjing SKF is the indentation and scratch of the bearing surface. When the situation is serious, the bearing will fall off. One thing you need to know is that burns often happen with this achievement.

影响南京SKF轴承损坏的***重要因素是轴承油膜的损坏，***后难以形成。

The most important factor affecting the damage of SKF bearings in Nanjing is the damage of bearing oil film, which is difficult to form after destruction.

三。空化损伤

Three. C***itation damage

与腐蚀不同，气蚀主要是由长期滑动轴承的反复冲击引起的，主要是由气缸压力引起的。当南京SKF轴承气蚀损坏时，主要是轴承表面硬化、变形、带裂纹、金属剥落等现象，轴承表面出现气穴现象。

Unlike corrosion, c***itation is mainly caused by repeated impact of long-term sliding bearings, mainly by cylinder pressure. When the Nanjing SKF bearing c***itation damage, mainly the bearing surface hardening, deformation, with cracks, metal spalling and other phenomena, bearing surface c***itation phenomenon.

滑动轴承空化腐蚀的主要原因是轴承内部存在气泡。压力越大，气泡越大。在一定程度上，这些气泡会消失并形成空化。

The main reason for c***itation corrosion of sliding bearing is the existence of bubbles inside the bearing. The greater the pressure, the bigger the bubble. To a certain extent, these bubbles will disappear and form c***itation.
