.1) The impact of one end of the shaft and the sliding bearing is usually caused by machining accuracy, mounting accuracy, bending deformation of the shaft, thermal deformation, etc. One end of the touch will form part of the overload; the oil film will break at the place; the metal surface will be directly touched. Touch; the conflict increases and abnormal wear occurs. /*250*250 was created on 2017/12/25*/ var cpro_id = 'u3171089';
The prevention and control method is: strictly ensure the oil film thickness of the bearing from the aspects of depiction, processing and installation; ensure the installation precision of the shaft and the bearing.
.2) Abnormal wear until the oil used for gluing is unsuitable, the oil contains impurities, the oil supply is insufficient, the roundness of the bearing hole and the shaft is out of tolerance, the installation is not proper, the data is not proper, and the shaft roughness is too large. Abnormal wear of plain bearings until gluing.
The prevention methods include: removing the smooth system, depicting and applying suitable filters, improving the machining accuracy and installation accuracy of the bearing holes and shafts, performing wear-resisting treatment on the bearing surface or using wear-resistant materials to ensure the viscosity, oiliness and oil supply of the oil. Quantity, etc.
.3) The shedding bearing appears to be detached on the outside due to the fatigue wear caused by the alternating load for a long time.
The prevention and treatment method is: selecting bearing alloy materials with good fatigue resistance; improving the strength of bearing alloys, etc.
.4) Corrosion is caused by the effect of acidic substances that occur after smooth oil degradation.
Control measures include: selection of corrosion-resistant alloy materials for bearing materials, selection of corrosion-resistant coatings, replacement of smooth oil in time.
