As an Auto Parts Wheel Bearing Factory, share with you. Now that you know that the bearing is slightly damaged, it is necessary to check and protect it. Today I will introduce to you how to view bearings and how to view them.
1. Viewing items in the working bearing inspection and fault handling work include: rolling sound, vibration, temperature, smooth condition of imported original bearings, etc.
2. The rolling sound of the bearing needs to use a sound detector to check the size and sound quality of the imported original bearing's rolling sound. Even if the bearing is slightly peeled and damaged, it will also emit abnormal sounds and irregular sounds. The sound device can be resolved.
3. The vibration of the bearing is very sensitive to the damage to the bearing. For example, shedding, indentation, rust, cracks, wear, etc. will be reflected in the bearing oscillation measurement. Therefore, after selecting a special bearing oscillation measuring device (frequency analyzer, etc.) The size of the oscillation is measured, and it is not possible to deduce anomalous details through the frequency. The measured values are different depending on the operating conditions of the bearings or the orientation of the sensor device, etc. Therefore, it is necessary to analyze and compare the measured values of each machine in advance and determine the judgment criterion.
4. With regard to the temperature of the bearing, generally the temperature outside the bearing can be estimated. It is more suitable if the temperature of the outer ring of the bearing can be directly measured by using oil holes. Generally, the temperature of the bearing gradually increases with the beginning of the work, and reaches a stable state after 1-2 hours. The normal temperature of the bearing varies with the heat capacity, heat dissipation, speed and load of the machine. If it is smooth and the device is suitable, the temperature of the Auto Parts Wheel Bearing will rise sharply, and it will show abnormally high temperature. At this time, it is necessary to suspend the work and adopt the necessary precautions. Because the temperature is affected by smoothness, speed, load, and environment, the values in the table only indicate the approximate temperature scale. The thermal sensor can be used to detect the working temperature of the bearing at any time, and when the temperature exceeds the specified value, it can actively alarm or stop to avoid the occurrence of burning shaft accidents.
