Roller roller bearing and its control method is when the bearing operation, rolling rolling rolling on the pavement and making a slide of a continuous sound, is typical of all bearings are essential. NSK bearings are roller sound with other sounds. Greater the rigidity of bearing, roller lower sound pressure level. Radial clearance is too small, acoustic sound pressure level and frequency of the Raceway will surge as the reduction in radial internal clearance.
Fatigue failure was a failure of the bearing surfaces, mainly for fatigue crack initiation and extension and fracture process, long-term effects of alternating load failures produced under the metal.
1, reasons: low overall bearing precision: selection of NSK bearings provides precision grade
2, reason: spindle not concentric bends or holes of the box method: repair of spindles or box
3, cause: the belt too tight: adjust belt tension proper
4, reason: poor lubrication method: select grades of lubricating materials and provided appropriate cleaning
5, reason: low Assembly quality: improving Assembly quality
6, reason: bearing shells lap method: replace the wear of bearings and related parts
7, method of axial force is too large: cleaning, adjusting seal ring gap required between 0.2~0.3mm, correct balancing of the impeller diameter and checking static balance value
8, bearing damage method: replace the NSK bearing
Control method of Raceway: Optional low noise bearings NSK bearings waviness is small, carefully selected conditions of use. Acoustic noise affecting the entire machinery of the Raceway, Raceway reduction can reduce the noise of the machinery as a whole.
