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.
精度損失是指由于原設計尺寸的變化而造成的精度損失。軸承雖然可以繼續轉動,但屬于異常運轉。其突出的性能是摩擦力矩、振動和溫升,通常由疲勞剝落、生銹、磨損、膠合等因素引起。空間滾動軸承和空間滾動軸承的失效模式主要是精度損失。
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,滾動軸承的常見失效模式如下:
At present, the common failure modes of rolling bearings are as follows:
(1)疲勞剝落:在接觸載荷作用下,滾動淮安SKF軸承內外環接觸面上的金屬和滾動體在金屬底座上按時或準時剝落。點蝕通常是疲勞剝落的初始形式,是由材料疲勞引起的疲勞現象。點蝕**終擴展到疲勞剝落。疲勞剝落與軸承材料、熱處理和制造工藝有關。同時,軸承的選擇、安裝、協調、潤滑、密封和維護也是造成疲勞剝落的重要原因。
(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)表面塑性變形:表面塑性變形可分為一般表面塑性變形和局部表面塑性變形。前者是由于兩個粗糙表面之間的接觸,導致兩個粗糙表面之間沒有流體潤滑淮安SKF軸承膜,后者是由于原始缺點(如凹坑和劃痕)導致材料表面局部塑性變形。
(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)磨損:疲勞磨損、粘著磨損、磨粒磨損和腐蝕磨損是磨損的基本形式。磨損主要是由于密封性不好、潤滑不當、顆粒脫落和接觸材料生銹造成的。通過改進裝配和加工工藝,加強潤滑,避免污染,減少磨損。
(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)腐蝕:金屬腐蝕可分為化學腐蝕和電化學腐蝕。軸承的腐蝕主要是由軸承或潤滑油中的堿、酸等腐蝕性物質引起的。密封裝置失效導致腐蝕性物質侵入,軸承濕度高,軸承清洗和存放不當。
(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)因滑動不當、預緊力過大、間隙選擇不當、槽接觸不穩定造成燒*傷。
(5) Burns are caused by improper sliding, excessive preload, improper gap selection and unstable groove contact.
(6)裂紋和缺點:當淮安SKF軸承零件的應力超過材料的斷裂極限應力時,材料的內部或表面整體和局部出現裂紋。裂紋和裂紋主要由原材料、熱處理和加工工藝引起。對原材料肉眼看不見的裂紋應進行無損檢測。
(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.
