FAG bearing is large production of machinery parts, and manufacturing precision requirements is strict, technology Shang professional degree is high, therefore for most easy buy to of bearing varieties,, should is purchased than repair more cost-effective, in addition to economic sexual yiwai, bearing of repair also has its technical, this on requirements repair who full understanding bearing corresponding of technology requirements, and bearing and parts in structure Shang, and technology Shang and material Shang of features, otherwise is difficult to guarantee FAG bearing repair has is requirements of effect.
(1) the benchmark unchanged combination repair method. At the time of repair and accuracy of dimension chain, according to baseline coincidence principle, only use a datum as the base, the design basis, while all other surface repairs to the surface as the base. This combination repair base, easy to check accuracy, reducing the accumulated error. For example, the variable speed fluid couplings in repair, usually bearing body as the base.
(2) datum transformation composite repair method. Sometimes design basis deformation is too large and cannot be used, choose other as the baseline, while dimension chain integration. For example, the FAG bearing deformation is too large, you should Swing components as the benchmark, reprocess-tuning of bearing, bearings and then processed according to the new size, adjust the Assembly dimension chains using fitting method of the adjustment ring, by order of dimension chain testing repair, final control precision of closed loop end.
Another role of FAG bearings seal is to prevent grease leaking from the bearing components. If the oil spill will quickly undermine the normal lubrication of bearings, bearing burned out because of a fever. Sealing undesirable not only afflicting conspicuous, but also pollution of machinery, equipment and processing products. Therefore, in order to make the machine run properly, FAG bearings a good seal is essential.
Select FAG bearing sealing device of the type you should consider the following factors:
1. bearing ring of magic.
2. the structural characteristics of bearing components.
3. the rotational speed of the bearing (bearing the circumference).
4. types of lubricants for bearings (lubricating oil or grease).
5.FAG the operating temperature of the bearing.
