The use of the TIMKEN bearing maintenance matters needing attention

TIMKEN bearing raceway groove sound sound and its control method is when a one-way 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 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. Control of raceway acoustic methods are: using low noise bearing is 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. Rolling bearing is precision components, and its use should be measured accordingly. No matter how high performance bearing use, if use undeserved, will not get the desired performance. About TIMKEN bearing the use of the matters needing attention are as follows: 1, carefully use in use for bearing strong impact, will produce scar and creasing, become the cause of the accident. Severe cases, can crack, fracture, so must pay attention to. 2, keep the bearing and its surrounding clean even the eyes can't see the little dust, will also bring bad influence to the bearings. So, keep the surrounding clean, dust from invading bearing. 3, using appropriate tools to avoid operation with existing tools to replace, must use the appropriate tools. 4, to pay attention to the corrosion of the bearing TIMKEN bearing operation, sweat will become the cause of rust. Pay attention to the operation with clean hands, it is better to try to bring gloves. 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, use with reasonable structure and material with kindliness one-way bearing cage.
