The rolling bearing way voice and control method is rolling say when running bearings, the roller on the way in rolling rolling sends out one kind of gliding continuous voice, is all FAG bearing happen every special basic sound. The general one-way bearing sound that is rolling and other way voice sound. The greater the rigidity of the bearing, roll say the lower the pressure level. Such as radial clearance is too small, the rolling say pressure level and the main frequency will be as radial clearance decreased sharply increase.

One-way bearing fatigue failure is a failure to surface forms, main show is fatigue crack initiation, expand, and fracture process, in alternate produced under the load of the fault of the long-term effects of metal. Cracks in two aspects:

1, on the surface, this is FAG in the rolling bearing contact process, as in the work of the surface of the plastic deformation and strain hardening the surface contact stress caused by the periodical change of external load function, and finally in small crack development from the inside surface, in between the formation of surface crack, because the job of the surface of the Xie into the lubricant, the power of the open, to crack down on on the wall, forcing crack forward;

2, from facing, under the pressure of repeatedly, the surface contact, first exposure to the surface where in certain depth crack the gap, and the Angle of direction along the surface, to certain depth, from the surface of the in response, and beyond to the surface, and finally form stripped corrosion, leaving a horse pit.

From one-way bearing on the surface, or from the surface crack, the two objectives (parts carburizing, quenching and other surface heat treatment, if uneven hardness after, organization, and the internal stress of non-uniform and other adverse, the contact stress generally have the opposite from under the influence of underground cracks, if parts surface quality is poor, there is a defect (oxidation, decarburization), friction or bad lubrication, from surface crack.
Roll control the way voice method: choose low noise FAG bearing namely small bearing striation, deliberate choice use conditions. Roll say often affect the entire machine noise, reducing groove sound can reduce the noise of the machinery.

One way of rolling bearings rolling sound and control method is run over with rolling cylindrical roller bearing in all cases it could have happened to harsh metal friction sound, occurs mostly in the larger type bearing grease lubrication, and in the performance degradation of oil complexes are more likely to happen, in oil lubrication almost does not occur. In addition, in winter are easy to occur, when subject to pure radial load, in radial clearance great occasion easy to occur, and with the different size, in a particular speed range easy to happen, not only will continuously happen and will appear intermittently. Foreign circle groove adopt the special processing method can prevent the emergence of rolling rolling sound and, when necessary, can choose the bearing, or reduced FAG bearing radial clearance, use the good performance of grease and improve and bearing match the rigid parts
