FAG bearing Raceway Raceway and its control method for FAG bearings operation, rolling rolling rolling on the pavement made slippery sounds in a row are all rolling FAG bearing specific basic sound occurs. FAG bearing Raceway acoustic sound that is combined with other sounds. Balls FAG bearing raceways are irregular, above 1000Hz frequency, frequency of rate changes with the speed, but the overall sound pressure level increases with accelerating speed of. FAG bearings Raceway, its acoustic sound pressure level Raceway diminishes with the increase of viscosity and sound little FAG bearing Raceway, its sound pressure level in the viscosity increases to about 20mm2/s above, by reduction to increased. More rigid you FAG bearings, roller lower the overall sound pressure level of sound. Radial clearance is too small, and Raceway total sound pressure level and frequency will increase sharply as the reduction in radial internal clearance. Method of controlling the rolling sound:
Use low-noise FAG FAG bearings bearing corrugated-small, carefully choose the conditions of use. Raceway often affects the entire mechanical noise, reduce Raceway can reduce the noise of machinery as a whole.
FAG bearings disassembly inspections, according to circumstances of FAG bearings FAG bearings injury trouble and cause of the damage.
1. surface metal Raceway spalling
FAG rolling bearings and on the inner and outer ring raceways are subjected to periodic pulse loads, resulting in periodic contact stress. When the number of stress cycles after a certain threshold is reached, in the rolling elements or inner and outer ring raceways produces fatigue spalling on the face. If the FAG bearing load is too large, will exacerbate this fatigue. In addition, the FAG bearing Setup is not straight, bent axis, roller flaking can also arise. FAG bearing Raceway fatigue spalling can reduce the running accuracy of the shaft, body vibration and noise.
2. the FAG bearing burn
FAG bearings burn on its roller, rolling temper. Reason is lack of lubrication, lubricants in general quality of burns or deterioration does not meet your needs, and FAG bearings fitted too tightly.
3. plastic deformation
FAG bearing raceways and rollers uniform does not appear on the contact surface of the crater, indicate the plastic deformation of FAG bearings. The reason for this is a FAG bearings under static and impact loads or loads of great, local stresses exceed the yield limit of material on the surface of the work, which generally occur in low-speed rotation of FAG bearings.
4. the FAG bearing seat cracks
FAG crack of bearing rings may be FAG bearing too tight, FAG bearing foreign or internal ring is loose, inclusive deformation of FAG bearings, FAG bearings installed processing poor surface.
5. cage fracture
The reason for this is lack of lubrication, rolling breaks, the seat tilt.
6. keep on rolling metal adhesion
Possible cause is the rolling was stuck in a cage or lack of lubrication.
7. seat Raceway badly worn
May is a circle out of the hands of foreign objects, insufficient lubricants or lubricant brands do not fit.
