IKO bearing the introduction of common cause damage

Most IKO bearing damage for many reasons, such as more than the original estimate of the load, the effective sealing, tight fit too small, as a result of bearing clearance, and so on. Any of these factors factors there is its special damage forms and will leave a special signs of deterioration. Examine the damaged bearing, therefore, in most cases can be found its possible reasons. Generally speaking, a third of the bearing damage is the result of fatigue damage, a third of the other is the result of bad lubrication, results from the third part of the other pollutants enter bearing improper handling or installation. However, the damage form is also related to the industrial difference. Pulp and paper industry, for example, mostly due to bad lubrication or pollution IKO bearing damage not caused by material fatigue; General bearing used in the manufacturing enterprises are caused by fatigue. Is not only a precious bearing need maintenance, is the common bearing also need maintenance, after all, a small screw is affect the global, if you think you can use longer IKO bearings, please always pay attention to these aspects. ( 1) Bearing raceway groove sound sound and its control method is when IKO bearing operation, the roller rolling on the surface of the raceway and 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 its total 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. And the rigidity of the bearing, the greater the raceway of the lower the total sound pressure level. Such as radial clearance is too small, the total sound pressure level and race master frequency will increase sharply with the decrease of radial clearance. Method to control the sound of raceway are: choose low noise IKO bearing waviness small IKO bearings, carefully select and use conditions. Race often affect the mechanical noise, reduce the raceway can reduce the mechanical noise. ( 2) 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. Control method of rolling body impact sound: decrease the radial clearance, materials for use with reasonable structure and flexibility of the bearing cage.
