INA overall eccentric bearing noise elimination method
The metallurgical quality of bearing materials used to be a major factor affecting the early failure of INA bearings. With the improvement of metallurgical technology (such as vacuum degassing of bearing steel), the quality of raw materials is improved. The proportion of raw material quality factors in the overall eccentric bearing failure analysis has dropped significantly, but it is still one of the main factors affecting bearing failure. The proper selection of materials is still a factor that must be considered in bearing failure analysis.
The main task of bearing failure analysis is to find out the main factors causing the failure of INA bearing based on a large amount of background materials, analysis data and failure modes, so as to propose improvement measures in a targeted manner and extend the service life of spherical roller bearings to avoid The bearing has a sudden early failure.
The vibration of the bearing has a significant effect on the failure of the bearing. For example: spalling, indentation, corrosion, cracks, wear, etc. will be reflected in the INA bearing vibration detection. Therefore, by using a special overall eccentric bearing vibration measuring device (frequency analyzer and vibration) The instrument can measure the magnitude of the vibration. The frequency of the vibration can be inferred. The measured value of the abnormal vibration is different depending on the premise of the INA bearing or the installation position of the sensor. Therefore, it is necessary to analyze and compare the measurement values of each machine in advance. After determining the judgment scale.
1. Reason: The overall eccentric bearing has low precision. The method selects the bearing with the specified accuracy grade.
2. Reason: The spindle is bent or the hole of the box is different. The method is to repair the spindle or the box.
3, the reason: the belt is too tight method: adjust the belt to make the elastic appropriate
4. Reason: Poor lubrication method: select the lubricating material of the specified grade and clean it properly.
5, the reason: low assembly quality method: improve assembly quality
6, reason: bearing inner casing running method: replacement of bearings and related wear parts
7. The axial force is too large. Method: Clean and adjust the clearance of the sealing ring. Between 0.2 and 0.3mm, correct the balance of the impeller and verify the static balance.
8, bearing damage method: replace INA bearinghttps://www.supplyforever.com/
