Steps For Inspection And Maintenance Of Fag One-Way Bearing

Raceway sound of bearing and its control method raceway sound is a smooth and continuous sound generated by the rolling body rolling on the raceway surface when the Fag One-Way Bearing shaft is running. It is a unique basic sound that will occur in all fag bearings.The general sound of one-way bearing is the sound of raceway plus other sounds. The greater the rigidity of the bearing pedestal, the Fag One-Way Bearing lower the sound pressure level of the raceway sound.

Fag One-Way Bearing

If the radial clearance is too small, the sound pressure level and dominant frequency of raceway sound will increase sharply with the decrease of radial clearance.
Fatigue failure of one-way bearing is a surface form of failure, which is Fag One-Way Bearing mainly manifested in the initiation, propagation and fracture process of fatigue crack, and the long-term impact of load failure under alternation. Cracks are in two ways:
On the surface, this is the external load caused by the plastic deformation of the working surface and the periodic change of the Fag One-Way Bearing contact stress of the strain hardened surface during the rolling contact process of fag bearing,and finally the formation of the surface crack between the two from the developing inner surface, due to the lubricant and the open force of the working surface, Crack down on the wall and force the crack to move forward.
From the surface layer, under repeated pressure, the contact of Fag One-Way Bearing the surface will initially produce cracks at a certain depth at the place where the surface is exposed,and from the angle along the surface direction to a certain depth, from behind the surface of the contact surface, and beyond the Fag One-Way Bearing surface, and finally form corrosion stripping, leaving a horse pit.

From the surface of one-way bearing,or from the cracks in the surface layer, these two objectives (carburization, quenching and other surface heat treatment of parts. If there is uneven hardness, organization, and non-uniform internal stress and other disadvantages, the contact stress is generally affected by the opposite underground cracks.
If the surface quality of parts is poor, there is a defect (oxidation, decarburization), Poor friction or Fag One-Way Bearing lubrication, cracks from the surface.
The methods to control the sound of raceway are: select low-noise fag bearings, that is, bearings with small waviness, and carefully select the service conditions. Raceway noise often affects the noise of the whole machinery. Reducing raceway noise can reduce the noise of the whole machinery.
Rolling sound of one-way bearing and its control method rolling sound is the harsh metal friction sound that can occur in cylindrical roller bearings on all occasions. Most of it occurs in larger types of grease lubricated bearings,
which is more likely to occur in greases with degraded base oil performance, and almost does not occur in oil lubrication. In addition, it is easy to occur in winter. When bearing pure radial load, it is easy to occur in the case of large radial clearance, and it is easy to occur in a specific speed range with different models and sizes,both continuously and intermittently.
Special processing methods for the outer ring raceway can prevent the occurrence of Fag One-Way Bearing rolling sound.
If necessary, this kind of bearing can be selected,or the radial clearance of fag bearing can be appropriately reduced, the lubricating grease with excellent performance can be used and the rigidity of parts matched with the bearing can be improved
