INA thin wall bearing running noise in solution

INA bearing in rolling bearing inspection project there is sound, vibration, temperature, lubrication condition and so on, are as follows: 1 bearing rolling sound use of the size of the audio equipment and sound quality sound check the operation of the thin wall bearing, bearing even slight detachment and other damage, abnormal intonation and the voice of the irregular measuring device is to distinguish the sound measurement. 2 bearing vibration of bearing vibration was highly sensitive to the damage of INA bearings, such as peeling, indentation, corrosion, cracks, wear, etc. Will be reflected in the bearing vibration measurement, therefore, through the use of special thin wall bearing vibration measurement ( Frequency analyzer, etc. ) , measuring the size of the vibration frequency analysis, can be inferred by unusual circumstances. For the position of the bearing under the condition of use or installation of sensors measured values are different, so each machine needs to be pre-determined standard analysis and comparison of measured values. 3, the temperature of the bearing temperature bearing, general bearing temperature outside the room, can be concluded that if the hole, can be used to directly measure temperature of bearing outer ring, is more appropriate. Normally, 1 - INA bearing temperature operation 2 hours, slowly to reach a steady state. Bearing the normal temperature of the heat capacity of the machine, heat capacity, speed and load changes. If the check and troubleshooting thin wall bearing lubrication operation, installation of the appropriate department, bearing temperature rise will be all of a sudden, the abnormal high temperature will stop running, take the necessary preventive measures. Block the increase rigidity, the lower the total sound pressure level, therefore this type of speed increase, the total sound pressure level did not increase. Grease lubricant viscosity is higher, but for, the lower the sound pressure level, the shape and size of soap fiber viscosity influence the noise value. No matter how to change the speed of the bearing factory, the main frequency noise sound pressure level is almost the same speed increase. Though straight thin-walled bearing raceway noise voice is inevitable, but can adopt high precision machining parts of the surface of the work, the correct selection and use, make the precision bearing vibration noise. Random vibration noise. Thin wall bearing ring, the natural vibration caused by load source of raceway. When the lubrication or the machining accuracy is not high, this will stimulate the INA bearing vibration inherent flexibility characteristics of moving into the air, and then passed to the noise. Because of race and rolling elements constitute a nonlinear elastic contact vibration system. When the increase of the radial clearance, sound pressure level significantly increased.
