IKO oilless bearing noise solution

Just running IKO bearing noise from race, would disappear with the increase of rotational speed. Running some time without oil bearing noise may also because isn't doing a good bearing lubrication, and installation. Impact of the rolling element and its control method for larger model of ball IKO bearings under pure radial load speed, due to centrifugal force is lesser, roller in the rolling body will impact the load area or race and making noises. But with the increase of rotational speed, the noise will disappear. Control method of rolling body impact sound: decrease the radial clearance, use with reasonable structure and material with kindliness IKO bearing cage. IKO bearing raceway groove sound sound and its control method is when the oilless bearing operation, its rolling on the surface of the raceway and rolling body a line of continuous sound, is unique to occur in all rolling bearings of the basic sound. General bearing ring raceway is combined with other sounds. Ball bearing raceway is irregular, frequency above 1000 hz, its main frequency does not change with speed, but the sound pressure level increases with speed to speed up. Raceway large bearings, the rolling sound of sound pressure level decrease with the increase of the viscosity; The raceway small bearings, the sound pressure level in the viscosity increases to about 20 was/s above, from decreased to increase somewhat. The rigidity of the bearing, the greater the raceway of sound pressure level is lower. Such as radial clearance is too small, the sound pressure level and the main frequency of the raceway sound can increase sharply with the decrease of radial clearance. Method to control the sound of raceway are: choose low noise oilless bearing is IKO bearing waviness is very small, that is, carefully select and use conditions. Race often affect the mechanical noise, reduce the raceway can reduce the mechanical noise. ( 1) Choose low noise IKO bearings; This will depend on the buy high quality bearing, generally good bearing steel is a high material, with high density, the characteristics of high patience; ( 2) Try to eliminate noise from the oilless bearing application link, is in the link above to add lubricating oil, must choose good lubrication materials, can be twice the result with half the effort; ( 3) Sensitive to avoid resonance with the host, to avoid the resonance speed; This need professional installation and debugging, can avoid resonance problem; ( 4) If the other method is invalid, sound insulation and noise elimination of additional measures to install some voice control equipment, etc. , roll bearing of rolling mill and its control method is IKO bearing in the harsh metal can occur in all occasions, mostly happens in large type bearing grease lubrication, and in the base oil performance degradation occurred more often in grease, almost does not occur when oil lubrication. In addition, more easily occur during the winter, when under pure radial load, the radial clearance prone to big occasions, and with different size, easy to happen in a certain speed range, both continuous and intermittent. External ring raceway take special processing method can prevent the occurrence of roll ring, can choose this kind of bearing, if necessary or appropriate to reduce the oilless bearing radial clearance, the use of high performance grease and improve to suit the bearing parts of rigidity.
