Shut-down fault of Huaian SKF bearing refers to the stop of rotation of bearing due to loss of working capacity, usually caused by jamming, fracture and other factors.
精度损失是指由于原设计尺寸的变化而造成的精度损失。轴承虽然可以继续转动，但属于异常运转。其突出的性能是摩擦力矩、振动和温升，通常由疲劳剥落、生锈、磨损、胶合等因素引起。空间滚动轴承和空间滚动轴承的失效模式主要是精度损失。
Accuracy loss refers to the loss of accuracy caused by the change of original design size. Although the bearing can continue to rotate, it belongs to abnormal operation. Its outstanding performance is friction moment, vibration and temperature rise, usually caused by fatigue spalling, rusting, wear, gluing and other factors. The failure modes of space rolling bearings and space rolling bearings are mainly accuracy loss.
目前，滚动轴承的常见失效模式如下：
At present, the common failure modes of rolling bearings are as follows:
（1）疲劳剥落：在接触载荷作用下，滚动淮安SKF轴承内外环接触面上的金属和滚动体在金属底座上按时或准时剥落。点蚀通常是疲劳剥落的初始形式，是由材料疲劳引起的疲劳现象。点蚀**终扩展到疲劳剥落。疲劳剥落与轴承材料、热处理和制造工艺有关。同时，轴承的选择、安装、协调、润滑、密封和维护也是造成疲劳剥落的重要原因。
(1) Fatigue peeling: Under contact load, the metal and rolling element on the contact surface of the inner and outer rings of rolling Huaian SKF bearings peel off on time or on time on the metal base. Pitting corrosion is usually the initial form of fatigue spalling, which is a fatigue phenomenon caused by material fatigue. Pitting corrosion eventually extends to fatigue spalling. Fatigue spalling is related to bearing material, heat treatment and manufacturing process. At the same time, the selection, installation, coordination, lubrication, sealing and maintenance of bearings are also important reasons for fatigue spalling.
（2）表面塑性变形：表面塑性变形可分为一般表面塑性变形和局部表面塑性变形。前者是由于两个粗糙表面之间的接触，导致两个粗糙表面之间没有流体润滑淮安SKF轴承膜，后者是由于原始缺点（如凹坑和划痕）导致材料表面局部塑性变形。
(2) Surface plastic deformation: Surface plastic deformation can be divided into general surface plastic deformation and local surface plastic deformation. The former is due to the contact between two rough surfaces, resulting in no fluid lubrication between the two rough surfaces Huaian SKF bearing film, the latter is due to the original defects (such as pits and scratches) resulting in local plastic deformation of the material surface.
（3）磨损：疲劳磨损、粘着磨损、磨粒磨损和腐蚀磨损是磨损的基本形式。磨损主要是由于密封性不好、润滑不当、颗粒脱落和接触材料生锈造成的。通过改进装配和加工工艺，加强润滑，避免污染，减少磨损。
(3) Wear: Fatigue wear, adhesion wear, abrasive wear and corrosion wear are the basic forms of wear. Wear is mainly caused by poor sealing, improper lubrication, particle shedding and rusting of contact materials. By improving assembly and processing technology, lubrication is strengthened, pollution is avoided and wear is reduced.
（4）腐蚀：金属腐蚀可分为化学腐蚀和电化学腐蚀。轴承的腐蚀主要是由轴承或润滑油中的碱、酸等腐蚀性物质引起的。密封装置失效导致腐蚀性物质侵入，轴承湿度高，轴承清洗和存放不当。
(4) Corrosion: metal corrosion can be divided into chemical corrosion and electrochemical corrosion. The corrosion of bearings is mainly caused by alkali, acid and other corrosive substances in bearings or lubricants. Failure of sealing device results in the invasion of corrosive substances, high bearing humidity and improper cleaning and storage of bearings.
（5）因滑动不当、预紧力过大、间隙选择不当、槽接触不稳定造成烧*伤。
(5) Burns are caused by improper sliding, excessive preload, improper gap selection and unstable groove contact.
（6）裂纹和缺点：当淮安SKF轴承零件的应力超过材料的断裂极限应力时，材料的内部或表面整体和局部出现裂纹。裂纹和裂纹主要由原材料、热处理和加工工艺引起。对原材料肉眼看不见的裂纹应进行无损检测。
(6) Cracks and shortcomings: When the stress of Huaian SKF bearing parts exceeds the material's fracture limit stress, the material's internal or surface cracks occur as a whole and locally. Cracks and cracks are mainly caused by raw materials, heat treatment and processing technology. Non-destructive testing should be carried out for cracks invisible to the naked eye of raw materials.
