SKF bearing lubrication technique solution of Raceway noise analysis

Rolling road sound source is due to ring the inherent vibration after the load. Due to the rings and rolling elements of nonlinear vibration of elastic contact form system. When lubricating or when machining accuracy is not high stimulation and the inherent vibration of elastic features, passing into the air becomes noise. As we all know, even using the most highly skilled manufacturing technology of processing components of SKF bearing, its surface will always exist with varying degrees of tiny geometric errors, so that between the raceways and rolling elements produce micro-wave excited vibration inherent vibration.
One, bearing oil lubrication method
Quantitative supply drops of lubricating oil for lubricating oil bearing part, drop a drop of oil content of individual 3-8 second, excessive amount of oil will cause increase in bearing temperature.
Second, bearing the oil bath lubrication method
Oil bath lubrication is the most common lubrication methods in SKF bearings, suitable for low and medium speed of SKF bearing lubrication. Bearing a partial immersion in a slot, lubricating oil by the rotation of the bearing components, then flow back into the oil tank oil level should be slightly lower than the center of the lowest rolling element.
Three, the radiation of the bearing lubrication
Oil pump low pressure oil nozzle Jet to bearings, into oil the bearings in the bearing flow oil Groove at the other end. In the bearings rotate at high speed, rolling and maintained also with commensurate high rotating speed so that the surrounding air causing air flow, with individual smooth way it is difficult to send the lubricant in the bearing when necessary using a low-voltage radiation of smooth oil spray to bearings, nozzle position should be placed between the inner ring and maintain Central.
Four, bearing lubrication method
Filtration of oil pump in oil sent to SKF bearing part, through the bearing lubricating oil filter again after cooling after use. Because of circulation oil can be taken away for sure heat, to cool off the bearing, therefore law practical for high speed bearing parts.
Five spray lubrication, bearings method
Dry shrinkage caused by air through sprayer mixed with varnish oil mist, radiology bearings, air can effectively cool the bearing and avoid intrusion. This method is suitable for high-speed, low-temperature bearing part is smooth.
Although bearing Raceway noise is inevitable, however high-precision machining parts surface can be taken, proper selection of SKF bearings and precise use of bearing making noise damping.
