The oscillation of imported bearings has significant effects on bearing failure. For example, peeling, indentations, corrosion, cracks, and wear can be reflected in the oscillation analysis of imported bearings. Therefore, special equipment such as frequency analyzers and oscillation meters can be used to measure the magnitude of oscillation. By analyzing the frequency distribution, specific information about abnormal oscillation can be inferred. The measured values may vary depending on the operating conditions of the imported bearings or the positioning of sensor devices. Therefore, it is necessary to analyze and compare the measurement values of each machine and establish predetermined criteria for judging imported bearings.
Typically, the temperature of imported bearings gradually increases as the operation starts and stabilizes after 1 to 2 hours. The normal temperature of imported bearings varies depending on the thermal capacity, heat dissipation, speed, and load of the machine. If lubrication and installation are not appropriate, the temperature of the imported bearings may rise rapidly, resulting in abnormally high temperatures. In such cases, it is necessary to stop the machine and take necessary preventive measures.
Smooth lubrication has a significant impact on the fatigue life, collisions, wear, temperature rise, vibration, and other factors of rolling imported bearings. Without proper lubrication, imported bearings cannot function properly. Analysis of the causes of bearing damage indicates that around 40% of imported bearing failures are related to poor lubrication. Therefore, excellent lubrication of INA bearings is an effective measure to reduce conflicts and wear in imported bearings.
In addition, proper lubrication of imported bearings also plays a role in heat dissipation, rust prevention, sealing, and shock mitigation. It is important to ensure that the lubricants are not expired or ineffective and that the selection of lubricants is correct. For harvesting machine imported bearings, there are two types of lubrication: oil lubrication and grease lubrication. For large models of gearbox, GL-5 80W90 gear oil is usually selected for oil lubrication. Lithium-based molybdenum disulfide grease is commonly used for grease lubrication. For the lower unit of a smooth torque converter, Mobil XHP222 or better grease lubrication is necessary.
