INA bearings in the application process because of their own quality and external conditions; its bearing capacity, rotation accuracy and wear resistance will change. When the function index of INA bearing is lower than the application demand and can not work normally; INA bearing will suffer from defects and even failure; after the accidental condition of INA bearing failure, the machine and equipment will stop; present various abnormalities such as utility loss Phenomenon; therefore, the need to detect the cause of the attack in a short period of time; and adopt the corresponding approach.
In order to make the INA bearing adhere to the function and use it for a long time under excellent conditions. It is necessary to view and protect the INA bearing; inspection and protection are important to prevent problems; in the operation, check the INA bearing's tumbling sound, oscillation, temperature and smoothing agent.
2. INA bearing oscillation
The oscillation of the INA bearing has a significant effect on the failure of the INA bearing. For example, shedding, indentation, rust, cracks, and abrasions are all reflected in the INA bearing oscillation test. Therefore, after selecting a special INA bearing oscillation measuring device (frequency analyzer and oscillator, etc.), the amplitude of the oscillation can be measured. The frequency distribution can infer the specific condition of the anomalous oscillation. The measured value is different due to the operating conditions of the INA bearing or the orientation of the sensor equipment. Therefore, it is necessary to analyze and compare the measurement values ​​of each machine beforehand and conclude the specification.
3. The temperature of the INA bearing usually increases the temperature of the INA bearing with the start of the operation, and reaches a stable condition after 1 to 2 hours. The normal temperature of the INA bearing is different due to the heat capacity, heat dissipation, speed and load of the machine. If it is smooth and the equipment is not suitable, the INA bearing temperature will rise sharply and it will show abnormal high temperature. At this time, it is necessary to stop and adopt the necessary precautions.
4. The smoothness of the smoothing agent has an important influence on the fatigue life of the tumbling INA bearing and the conflict, wear, temperature rise, oscillation, etc., without normal smoothness, the INA bearing can not work. Analysis of the damage of the INA bearing is indicated by the fact that about 40% of the INA bearing damage is related to poor smoothness. The outstanding smoothness of the INA bearing is therefore a useful way to reduce INA bearing conflicts and wear. In addition, the smoothness of INA bearings also contributes to heat dissipation, rust prevention, sealing, and flat cushioning. To ensure that the smoothing agent does not expire, the selection should be correct. Harvester INA bearing smooth and oily smooth and grease smooth two, large model gearbox oil smooth selection with GL-580W90 gear oil; grease smoothing usually with molybdenum disulfide lithium-based smooth grease, smooth torque increaser stepless shifting lower It is necessary for the equipment to be smooth with Mobil XHP222 or better grease.
