The function of the automobile bearing is to support, and the bearing relies on the rolling contact between the components to support the transmission parts, so it has the characteristics of small sliding resistance, low power consumption, and easy starting.
Bearings have an important impact on the performance of the vehicle. In terms of reliability, once damaged, it will affect the driving of the vehicle. In terms of safety, the installation position of some bearings is very important, such as hub bearings, which are to support the weight of the entire vehicle. Once a failure occurs, it will affect the safety of the entire vehicle. In terms of comfort, bearings are not only closely related to the smooth operation of the vehicle, but also those bearings with poor quality are prone to generate greater noise.
The secret of the maintenance method of automobile bearings:
1. The vehicle should work within the rated load range. If it is seriously overloaded, it will directly cause the bearing to be overloaded, which will cause early failure of the bearing, and more seriously, it may cause vehicle failure and personal safety accidents.
2. It is necessary to prohibit the bearing from being subjected to some abnormal impact loads.
3. It is necessary to regularly check the use status of the bearings, and pay attention to whether there are abnormal noises or local sharp temperature rises in the bearing parts.
4: Lubricating oil or grease should be added regularly and quantitatively as required to ensure the normal operation of the bearing.
5. According to the usage status of the vehicle, the lubricating oil should be completely replaced at least every six months, and the bearing should be carefully inspected to prevent accidents.
6.The inspection method of the shaft in the maintenance state is: clean the disassembled bearing with kerosene or gasoline, carefully observe whether there is sliding or creeping on the inner and outer cylindrical surfaces of the bearing, and also look at the inner and outer raceway surfaces of the bearing Whether there is peeling and pitting, and whether there is wear and deformation of the rolling elements and cages, etc. We can judge whether the inspected bearing can continue to be used according to the comprehensive situation of the bearing inspection.
