conversations.value: Roupeda: Only send bearing noise work path, with the increase of rotational speed, disappeared. Oil-free bearings work sometimes also can send voice for bearing lubrication and installation is no good.
  Acoustic shock and rolling element bearing model control method under large pure radial load low speed work, due to centrifugal force with no load roller rolling body or send shock separator, path noise. But as the speed increases, the sound disappeared.
  Voice to impact roller: related management methods to reduce the radial clearance, reasonable structure, it USES material with gentle character bearing cage.
  Bearing on the racecourse voice and audio path oilless  SKF Bearings  management method, the rolling road face, rolling roller in continuous smooth rolling bearing, all major sound unique voice. General bearing voice is the voice of the racecourse, combined with other sounds. Ball bearing, the racecourse sound frequency is wrong, in the above 1000 hz frequency and speed change is not true, but the sound pressure level increases, accelerate the turnover. The racecourse voice big bearing, lawn audio sound pressure level to reduce the viscosity of growth path; Sound small bearings, the sound pressure level increasing viscosity is about more than 20 was/s. Big pillow, stiffness ratio dropped sound path. As the radial clearance is too small, the lawn audio sound pressure level and the main frequency will increase as the radial clearance decreased sharply.
  Management path selection methods are: voice low noise bearing without oil bearing, namely the ripple is small, carefully selected conditions of use. The sound part of the racecourse, reduce machine noise acoustic path can reduce the mechanical noise.
  (1) choose low noise bearings; Depending on to buy high quality bearings, bearings, write good is high, the steel material has high stability, especially high density;
  (2) from the oil bearing application link to eliminate the noise, the fat is in the above link + oil must choose good lubricant, can impact;
  (3) does not occur resonance, the resonance speed to avoid the host sensitive; This problem need professional installation and debugging, can avoid resonance;
  (4) if the other method is invalid, to take further measures to isolate and sound editing equipment, some voice control and so on.
  Bearing is bearing and the pay-off pay-off method control sound sharp metal friction in all cases, mainly in the grease lubricated bearing, large oil lubrication performance deterioration occurs mainly in oil almost does not occur. In addition, in the winter, when there is lighter, when under pure radial load, radial clearance miracle lung type and size is different from the specific speed range, is easy to occur, continuous interruptions. Outer ring raceway take special treatment can prevent sound, choose when necessary without oil bearing, bearing radial clearance, or appropriate to reduce the use of high performance, improve the lubrication bearing rigid institutions.
