接触游隙的镇江SKF轴承失效三要素

镇江SKF轴承接触疲劳失效是承受交变应力的轴承表面失效。滑动轴承的接触疲劳剥落常伴有疲劳裂纹。首先，接触表面下面的大交变剪应力开始并延伸到表面，形成不同的剥落形状，例如点蚀或点蚀剥落和剥落。一个叫做浅剥落的小块。剥落面逐渐膨胀，倾向于向深处层次扩展，形成深剥落。深剥落是接触疲劳失效的疲劳源。

The contact fatigue failure of SKF bearing in Zhenjiang is the failure of bearing surface subjected to alternating stress. The contact fatigue spalling of sliding bearings is often accompanied by fatigue cracks. First, the large alternating shear stress below the contact surface begins and extends to the surface, forming different exfoliation shapes, such as pitting or pitting exfoliation and exfoliation. A ***all piece called shallow spalling. The spalling surface expands gradually, tends to extend to the deep level, forming deep spalling. Deep peeling is the fatigue source of contact fatigue failure.

轴承在工作中，由于外部或内部的因素，使原有间隙发生变化，精度降低，甚至造成“咬死”称为间隙变化失效。镇江SKF轴承过干涉、安装不当、温升引起的膨胀、瞬态过载、残余奥氏体等内部因素和不稳定状态下的残余应力是导致空洞转变失效的主要原因。

Bearing in the work, because of external or internal factors, so that the original clearance changes, precision is reduced, or even cause "bite dead" called clearance change failure. Internal factors such as excessive interference, improper installation, expansion caused by temperature rise, transient overload, retained austenite and residual stress in unstable state are the main reas*** for void transformation failure of Zhenjiang SKF bearing.

磨损失效是金属表面相对于滑动摩擦的失效。持续的磨损会导致轴承零件的逐渐损坏，终导致轴承尺寸精度损失等相关问题。镇江SKF轴承磨损会影响轴承的形状、配合间隙的增加和工作表面形貌的变化，可能影响润滑剂或使其受到一定程度的污染，导致润滑功能的丧失，使轴承的旋转精度甚至不能工作。失业。玛丽。磨损失效是各种轴承常见的失效形式之一，可分为常见的磨粒磨损和粘着磨损。

Wear failure is the failure of metal surface relative to sliding friction. Continuous wear and tear will lead to the gradual damage of bearing parts, and eventually lead to the loss of bearing dimensional accuracy and other related problems. The wear of Zhenjiang SKF bearing will affect the shape of the bearing, the increase of fit clearance and the change of working surface morphology. It may affect the lubricant or cause it to be polluted to a certain extent, resulting in the loss of lubrication function and even the rotation accuracy of the bearing can not work. Unemployment. Marie. Wear failure is one of the common failure forms of various bearings, which can be divided into abrasive wear and adhesive wear.

首先，合理的设计和***的结构将导致镇江SKF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，磨削过程与轴承表面质量密切相关。

First of all, reasonable design and advanced structure will lead to longer life of SKF bearings in Zhenjiang. 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 bearing products are directly related to the failure of bearings. In recent years, the research on the deteriorating layer of the bearing working surface shows that the grinding process is closely related to the bearing surface quality.

轴承材料的冶金质量是影响滚动镇江SKF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，原材料的质量获得了提高。

The metallurgical quality of bearing material is the main factor affecting the early failure of rolling SKF bearing in Zhenjiang. With the progress of Metallurgical Technology (such as vacuum degassing of bearing steel), the quality of raw materials has been improved.
