The vibration of imported bearings has a significant impact on their failure. For instance, phenomena such as spalling, indentation, rust, cracking, and wear are all reflected in the vibration testing of imported bearings. Therefore, by using special imported bearing vibration measurement equipment (frequency analyzers, vibration meters, etc.), the magnitude of the vibration can be measured. The specific conditions of abnormal vibrations can be inferred from the frequency distribution. The measured values can vary due to the operating conditions of the imported bearings or the orientation of the sensors, so it is necessary to analyze and compare the measurement values of each machine beforehand to determine the criteria for selecting imported bearings.
Typically, the temperature of imported bearings gradually increases as the operation begins, reaching a stable state after about 1 to 2 hours. The normal temperature of imported bearings varies due to the machine's heat capacity, heat dissipation, speed, and load. If lubrication or installation is improper, the temperature of the imported bearings can rise sharply, leading to abnormally high temperatures. In such cases, it is necessary to shut down the machine and take the necessary precautionary measures.
Smoothness is crucial for the fatigue life and wear resistance of imported roller bearings, as well as for minimizing friction, wear, temperature rise, and vibration. Without proper smoothness, the imported bearings cannot operate effectively. Analysis of the causes of imported bearing damage indicates that about 40% of such damages are related to poor lubrication. Therefore, INA's lubrication is an effective measure to reduce friction and wear in imported bearings.
In addition, the smoothness of imported ball bearings plays a role in heat dissipation, rust prevention, sealing, and shock absorption. It is crucial to ensure that the lubricant does not expire or become ineffective, and the selection must be accurate. The smoothness of imported combine harvester ball bearings comes in two types: oil-based and grease-based. For large machinery gearboxes, choose GL-5 80W90 gear oil; grease-based lubrication typically uses molybdenum disulfide lithium-based grease. The variable speed transmission unit of the smooth torque enhancer must use Mobil XHP 222 or a superior grease lubricant.
