FAG automotive bearings use check and maintenance points during operation

The inspection of the automotive bearings during operation is very important and cannot be ignored. It mainly checks the rolling sound, vibration, temperature, lubrication status of the bearings and so on. Let us briefly introduce the rolling sound of FAG bearings. The size of the rolling sound and the sound quality should be checked by the sounder to check the running car bearings. The advanced tools will accurately determine the problem. Bearings Even with slight peeling and other damage, abnormal sounds and irregular sounds are emitted, which can be distinguished by the sounder.

Then the vibration of the car bearing is checked to see if the damage of the bearing is very sensitive. Whether it is peeling, indentation, rust, crack, wear, etc. will be reflected in the vibration measurement of the FAG bearing. Therefore, by using a special automotive bearing vibration measuring device (frequency The analyzer can measure the magnitude of the vibration, and the specific situation of the abnormality cannot be inferred by the frequency division. However, the value measured by each machine differs depending on the conditions of use of the bearing or the mounting position of the sensor. Therefore, it is necessary to analyze and compare the measured values ​​of each machine in advance to determine the judgment standard.

1. When using the car bearing, connect the surrounding environment cleanly, do not stick sweat and dirt. It is delineated by the staff who know the bearing, and it is especially necessary to be careful about acid, indentation, damage, etc. In order to ensure the function of the bearing, the FAG bearing should be protected, nursed and inspected according to the equipment's homework scale. The form includes monitoring the operation status, making up the smoothing agent, and checking the assembly on schedule.

2, bearings should not be stored directly on the ground (need to be more than 30cm off the ground) to prevent direct light and cold walls. In order to prevent rust, it is stored in an environment with a temperature of about 20 ° C and a humidity of 65%. The car bearings are arranged in an acidic atmosphere, which is prone to rust and discoloration. Gloves and kapok are used to wipe the bearings, shafts, and outer casings. The external and common sectors of FAG bearings are the cause of anomalies, and are necessary to be meticulous.

3, bearing measurement deviation, should be 10% of the public service as follows. The general measurement deviation value is 10% to 33%, and with the progress of the public service grade, the greater the proportion of deviation, that is, the smaller the public service, the higher the proportion of deviation, and the public service of the automobile bearing Above IT5, it is difficult to reach 10%. Measuring deviations not only means that the inspection of public service can be relaxed by 10%, but to give a certain safety margin to ensure that the user accepts the pass according to the scale.

4. Before the vehicle bearings are inspected, they must be arranged in a metal plate in the inspection occasion with the gauge block, the scale member and the measuring instrument used for the inspection. If the temperature of the objects is allowed to be uniform and room temperature is allowed to be faster. Bearings that have been dried or dried should be dripped into the smooth oil and immediately entrusted for inspection. At this time, there is no oil film shelter outside the FAG bearing. In all the inspection processes, the skin should not be directly hit and the operator should wear it. Clean gloves, or apply anti-rust agent on the hand, but it is necessary to prevent the anti-rust agent on the hand from mixing into the rotation of the car bearing, otherwise the measurement result will be faulty.https://www.supplyforever.com/
