INA roller bearings rolling noise occurs causes and treatment methods'

Kunshan bearing manufacturer  vibration on INA roller bearing damage can be said to be commensurate with the sensitivity, peeling, dents, rust, cracks, wear, etc. will be in INA roller bearing vibration measuring reflected. Thus, by the use of special bearing vibration measurement can be measured size of the vibration, can be inferred by the frequency distribution of abnormal circumstances. The measured values ​​due to the use of roller bearings INA premise or sensor installation location is different, so each machine needs prior to analysis and comparison of measured values ​​determined after judgment scales.
     Temperature effects on the INA roller bearings, high temperature bearings are often expressed in an abnormal situation. Temperature is harmful INA roller bearing lubricant. Sometimes bearing overheating can be attributed to the bearing lubricant. If the bearing temperature over 125 ℃ even move to reduce long bearing life. Caused by high temperature bearings factors: lack of lubrication or excessive lubrication, the lubricant containing impurities, the load is too large, INA roller Bearing test machine wear, lack of space, and produce high-friction seals and so on.
   Therefore, continuous monitoring of INA roller bearing temperature is necessary, whether it is measuring the bearing itself, or other important parts. If the operating conditions remain unchanged in the case of temperature change can be said of any fault has occurred.
    Sweden INA roller bearing raceway raceway sound and control the sound is running when the bearing, which move the body to move in a raceway issued a slippery continuous sound, move the bearing will happen to all the unique basic sound. Generally equal to the raceway of the bearing acoustic sound plus other sounds. Ball bearing raceway sound is irregular frequencies above 1000Hz, its main frequency does not change with the speed, but the total sound pressure level increases with the speed acceleration. Bearing raceway loud, the sound pressure level of its raceway with the viscosity decreases with increasing; while the sound of a small roller bearings, and its level increased in viscosity to about 20mm2 / s or more, by reducing the transfer is somewhat increased.
    Greater rigidity of bearing raceway total sound pressure level is lower. If the radial clearance is too small, the total sound pressure level raceway and the main frequency will follow the reduction in radial clearance increased dramatically. Control raceway sound methods are: selection of low-noise bearings that waviness small bearings, carefully choose to use the premise. Raceway sound often affect the entire mechanical noise reduction raceway sound can reduce the overall mechanical noise.
    INA roller bearings jarring sound and control jarring sound is a cylindrical roller bearings on all occasions that may occur harsh impolite metal friction sound, mostly in grease lubricated bearings in larger models, while functions in the base oil more susceptible to deterioration of grease, oil lubrication in almost no time. In addition, more prone to winter, when subjected to pure radial load, radial clearance in big occasions easily occur, and with models of different sizes, at a particular speed range prone to both occur consecutively would intermittently thrown. INA roller bearing outer ring raceway take special processing methods to prevent jarring sound of a comeback, when necessary, use this bearing, or appropriate to reduce the radial clearance, using functional excellent match with the bearing grease and progress mechanical rigidity.
