Bearing additional sealing selection should pay attention to what matters?
As we all know, in order to make the bearing seal bearing can in good lubricating conditions and normal working environment, give full play to the performance, prolong the service life of the bearing, and to prevent lubricant leakage and dust, vapor, or other pollutants invasion.
Its bearing seal is mainly divided into its own seal and external seal, with its own seal, mainly refers to the bearing itself is made into a sealing device, such as bearings, with dust cover, sealing ring and so on. The sealing space is small, and the installation and disassembly are convenient, and the cost is relatively low.
The so-called bearing additional sealing performance device, refers to the installation of end caps and other internal manufacturing into a variety of performance sealing devices, and bearings with the choice of sealing, we must pay attention to the following matters.
1, bearing lubricant and types (grease and oil), the working environment of the bearing, space size, the utility model has the advantages of supporting structure, allowing the angle deviation, sealing surface circumferential velocity, the bearing temperature, manufacturing cost.
2, the vehicle should be within the rated load range, if serious overloading will lead directly to bearing overload, will lead to early failure of bearings, more serious will cause vehicle failure and personal safety accidents.
3 、 forbid the axle to bear the abnormal impact load.
4, regularly check the use of bearings, pay attention to observe the bearing parts are abnormal sound and local sharp temperature rise phenomenon, according to requirements, regular and quantitative filling lubricating oil or grease.
5, according to the use of vehicles, at least every six months to completely replace the lubricating oil, and the bearings carefully checked.
6, under the condition of bearing maintenance inspection: the disassembly of the bearing under the kerosene or gasoline clean, carefully observe the inner and outer cylindrical surface of the bearing is a sliding or creeping phenomenon, bearing inner raceway surface without spalling, pitting, rolling body and cage for wear and deformation, according to the overall situation of the bearing check whether to continue to use, the judgment of the bearings. |
