Does bearing oscillation have an impact on bearing failure

The oscillation of bearings has a significant impact on bearing failure, such as peeling, indentation, rust, cracks, wear, etc., which can be reflected in bearing oscillation detection. Therefore, the magnitude of oscillation can be measured by using special bearing oscillation measurement equipment (frequency analyzers and oscillators, etc.), and the specific situation of abnormal oscillation can be inferred through frequency dispersion. The measured values vary depending on the service conditions of the bearing or the orientation of the sensor device, Therefore, it is necessary to analyze and compare the measurement values of each machine in advance to determine the judgment standard bearing.

Usually, the temperature of the bearing gradually increases with the start of work and reaches a stable state after 1 to 2 hours. The normal temperature of the bearing is different due to the Heat capacity, heat dissipation, speed and load of the machine. If the lubrication and device are not suitable, the bearing temperature will rise sharply, and abnormal high temperature will occur. At this time, it is necessary to stop the machine and take necessary preventive measures.

Smoothness has a significant impact on the fatigue life and conflict, wear, temperature rise, vibration, etc. of rolling bearings. Without normal smoothness, bearings cannot operate. Analyzing the causes of bearing damage indicates that about 40% of bearing damage is related to poor smoothness. Therefore, the outstanding smoothness of INA bearings is a useful measure to reduce bearing conflicts and wear.

In addition, the smoothness of bearings also plays a role in heat dissipation, rust prevention, sealing, and impact mitigation. To ensure that the smoothing agent does not expire, the selection should be correct. The bearing of the harvester has two kinds of smooth oil separation: smooth and grease smooth. GL-5 80W90 Gear oil is selected for the large model gearbox; Molybdenum disulfide lithium base grease is generally used for grease smoothing, and the lower device of the smooth torque increaser CVT must be smooth with Mobil XHP222 or better grease
