Plastic bearing of rolling mill and its control method for roll 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.
First of all, the impact of the rolling element and its control method for larger models of ball bearings or cylindrical roller 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.
Followed by the plastic bearing raceway groove sound sound and its control method is when bearing is running, the roller rolling on the surface of the raceway and a line of continuous sound, happened all IKO bearing characteristic 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 plastic 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 ring can increase sharply with the decrease of radial clearance, if you don't want it to have a voice, the best thing to do is to turn off the electricity, ha ha, actually we can use some maximum measures of reducing the noise of the bearing, generally speaking, trying to control the noise impact of IKO bearings, it must take countermeasures in view of the source of the noise, and to receive the cure effect.
In addition, more easily occur during the winter, when the plastic bearings of 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, if necessary, can choose the IKO bearings, or decrease the bearing radial clearance, the use of high performance grease and improve to suit the bearing parts of rigidity.
