IKO CAM bearing lubrication knowledge skills to solve noise analysis - bearing raceway
Raceway acoustic source lies in the inherent vibration caused by ring after exposure to the load.
Because of the ring and rolling body elastic contact nonlinear vibration system.
When lubrication or the machining accuracy is not high will stimulate the related to the elastic characteristics of natural vibration and passed to the was noise in the air.
As is known to all, even if is to use the contemporary the most advanced manufacturing technology and processing IKO bearing parts, there will always be the working surface of varying degrees of tiny geometric error, thus make the raceway and rolling body produces slight fluctuations inherent vibration excitation vibration system.
A, bearing lubrication oil drops oil lubrication is suitable for need to ration oil bearing parts, drops of oil every 3 - individually
A drop of it is advisable to 8 seconds, too much oil will cause the bearing temperature increased.
Second, and CAM bearing oil bath lubrication oil bath lubrication is common in the CAM bearing lubrication way, suitable for low and medium speed IKO bearing lubrication.
Bearing a partial immersion in the slot, the bearing parts of lubricating oil by rotating, then flow back to the oil level of oil tank should be slightly lower than the lowest in the middle of the roller.
Three radiation lubrication, bearings with oil pump nozzle shot into the bearing, the oil in the low pressure into the bearing of the bearing at the other end into the oil in the tank.
When bearing at high speed, rolling body and maintain frame to match the rotation of the high speed air cause air flow around, it is difficult to be sent to the bearing lubricating oil in individual smooth way, then must smooth oil spray with low radiation to bearing, the status of the nozzle should be placed in the middle of the inner ring and maintain frame between.
Four, the cycle of bearing lubrication oil pump will be filtered oil walks to the CAM bearing parts, through the bearing lubricating oil filter cooling after use.
Because circulating oil can take away heat, must make IKO bearing cooling, therefore method suitable for high speed bearing parts.
Five, spray lubrication of the bearing with air dry contraction after the sprayer and smooth oil mixed oil mist, radial bearings, can effectively make the bearing cooling airflow and can avoid intrusion.
This method is suitable for high speed and low temperature bearing parts is smooth.
Despite the rolling bearing noise is unavoidable, but can take work surface precision machining parts, the correct selection of bearing and precise use of bearing noise vibration reduction.
