Automotive Bearing Tapered Roller Tapered roller bearing is a radial thrust type rolling bearing with tapered roller body.There are two kinds of small cone Angle and large cone Angle. The small cone Angle mainly bears the combined radial and axial load mainly in the radial load, often in double use, reverse installation, the inner and outer seat ring can be installed separately, in the installation and use can adjust the radial and axial clearance; The large cone Angle is mainly used to bear the combined axial and radial loads, which are mainly axial loads.
The failure of Automotive Bearing Tapered Roller is normal and can be judged by reasonable surface phenomena at the early stage.The bearing temperature is too high is an important reason, the quality of the lubricating oil does not meet the requirements or deterioration, the viscosity of the lubricating oil is too high, the structure of the assembly is too tight, the gap is insufficient, the bearing assembly is too tight. Seat ring corrosion, spectral analysis found that the concentration of non-ferrous elements is abnormal, a lot of non-ferrous metal components in the ferrography submicron wear particles, lubricating oil moisture exceeds the standard, acid value exceeds the standard. The surface of inner and outer ring is pulled.
There are iron cutting abrasive particles or black oxide particles in ferrograph. The surface of inner and outer rings was corroded, and the spectral analysis showed that the concentration of iron was abnormal. There were many submicron particles of iron in the iron spectrum, and the lubricating oil moisture or acid value exceeded the standard. Surface strain, ferrography found in the cutting abrasive grain, abrasive grain composition for non-ferrous metals. The inner and outer ring was fretting wear, and the spectral analysis showed that the iron concentration was abnormal, there were many iron submicron wear particles in the iron spectrum, and the moisture and acid value of the lubricating oil were abnormal. Under the condition of liquid lubrication, the sliding surface is separated by lubricating oil without direct contact, which can greatly reduce the friction loss and surface wear.
