镇江NSK轴承润滑不足等过程性问题的探究

轴承滚道与滚子接触面上的凹痕表明轴承具有塑性变形。其原因是工作面的局部应力在大的静载荷或冲击载荷下超过材料的屈服极限，并且通常发生在低速旋转轴承上。

The dent on the contact surface between the bearing raceway and the roller indicates that the bearing has plastic deformation. The reason is that the local stress of working face exceeds the yield limit of material under large static load or impact load, and usually occurs on low-speed rotating bearings.

轴承套圈产生裂纹的原因可能是轴承配合过大、镇江NSK轴承内外圈松动、轴承变形、轴承表面加工效果不足等。

The causes of bearing ring cracks may be excessive bearing fit, loose inner and outer rings of Zhenjiang NSK bearing, bearing deformation, bearing surface processing effect is not enough.

原因是润滑不足、阀门断裂和阀座歪斜。

The reason is lack of lubrication, valve breakage and seat skew.

可能的原因是身体被困在笼子里或没有润滑。

The possible reason is that the body is trapped in a cage or not lubricated.

任何镇江NSK轴承的使用寿命在很大程度上取决于它的维护和接收。在苛刻的工作条件、重载、灰尘和污染是常见的尺寸的工业应用中尤其如此。

The service life of any NSK bearing in Zhenjiang depends to a large extent on its maintenance and reception. This is especially true in industrial applicati*** where harsh working conditi***, he***y loads, dust and pollution are common dimensi***.

首先，合理的设计和***的结构将导致轴承寿命更长。轴承的制造通常是通过锻造、热处理、车削、磨削和装配来完成的。各种加工技术的合理性、***性和稳定性也会影响轴承的寿命。影响镇江NSK轴承产品质量的热处理和磨削工艺直接关系到轴承的失效。近年来，对轴承工作表面变质层的研究表明，磨削过程与其表面质量密切相关。

First, reasonable design and advanced structure will lead to longer bearing life. The manufacture of bearings is usually done by forging, heat treatment, turning, grinding and assembling. The rationality, advancement and stability of various processing technologies will also affect the life of bearings. The heat treatment and grinding processes that affect the quality of NSK bearing products in Zhenjiang are directly related to the failure of bearings. In recent years, the research on the deteriorating layer of bearing working surface shows that the grinding process is closely related to its surface quality.

然后，根据大量的背景数据、分析数据和故障形式，找出导致轴承失效的主要因素，然后提出改进措施，延长轴承的使用寿命，避免突发性***，是轴承失效分析的主要原因。失败。

Then, according to a large number of background data, analysis data and failure forms, find out the main factors that lead to bearing failure, and then propose improvement measures to prolong the service life of bearings, ***oid sudden tinnitus, is the main reason for bearing failure analysis. Failure.

轴承材料的冶金质量是影响滚动镇江NSK轴承早期失效的主要因素。随着冶金技术（如轴承钢的真空脱气）的进步，原材料的质量取得了提高。在轴承失效分析中，原材料质量因素的比例显著降低，但仍是影响轴承失效的主要因素。轴承失效分析中应考虑材料的选择。

The metallurgical quality of bearing material is the main factor affecting the early failure of rolling NSK bearing in Zhenjiang. With the progress of Metallurgical Technology (such as vacuum degassing of bearing steel), the quality of raw materials has been improved. In bearing failure analysis, the proportion of raw material quality factors is significantly reduced, but it is still the main factor affecting bearing failure. Material selection should be c***idered in bearing failure analysis.

内圈和外圈的轴承和滚道表面受到周期性波动载荷，导致周期性接触应力。当应力循环次数达到一定值时，滚道表面或内外滚道均发生疲劳剥落。如果轴承载荷过大，则会加剧疲劳。此外，如果轴承错位，轴弯曲，滚道就会脱落。

The bearing and raceway surfaces of the inner ring and outer ring are subjected to periodic fluctuating loads, resulting in periodic contact stresses. When the number of stress cycles reaches a certain value, fatigue exfoliation occurs on raceway surface or inside and outside raceway. If the bearing load is too large, it will aggr***ate fatigue. Besides, if the bearing is misplaced and the shaft is bent, the raceway will fall off.
