Accurate Installation Can Effectively Control The Noise Of Ina Imported Bearing

Ina Imported Bearing

Raceway sound of ina imported bearing and its control method raceway sound is a smooth and continuous sound made by the rolling body rolling on the raceway surface when the shaft is running. It is a unique basic sound that will occur in all bearings. The general bearing sound is the raceway sound plus other sounds.

The greater the rigidity of the bearing pedestal, the lower the sound pressure level of the raceway sound. If the radial clearance is too small, the sound pressure level and dominant frequency of raceway Ina Imported Bearing sound will increase sharply with the decrease of radial clearance.

The fatigue failure of ina imported bearing is a failure surface form, which is mainly manifested in the initiation, propagation and fracture process of fatigue crack, and the long-term impact of load failure under alternation. Cracks in two ways

From the bearing surface, or from the cracks in the surface layer, These two objectives (carburizing, quenching and other surface heat treatment of parts). If there are uneven hardness, microstructure, and Ina Imported Bearing non-uniform internal stress and other disadvantages, the contact stress is generally under the influence of opposite underground cracks. If the surface quality of parts is poor, there is a defect (oxidation, decarburization), poor friction or lubrication, and surface cracks.

The methods to control the raceway sound are: select low-noise bearings, that is, ina imported bearings with small waviness, and carefully select the service conditions. Ina Imported Bearing Raceway noise often affects the noise of the whole machinery. Reducing raceway noise can reduce the noise of the whole machinery.

Accurate Installation Can Effectively Control The Noise Of Ina Imported Bearing

(1) Bearing raceway and sound control method are ina imported bearings when running.

On a continuous rolling sliding surface, they are printed with distinctive production ball foundation. In other words, Ina Imported Bearing the overall sound of roller bearings with other sounds. The ball rolling is irregular, and the above 1000Hz frequency will not change the main frequency of speed change, but the overall speed will rapidly increase the sound pressure level.

His influence on the raceway, the raceway sound pressure level is increased, the viscosity decreases, and the sound pressure level of a small roller bearing with medium viscosity increases is sound, Ina Imported Bearing which is related to 20 mm2 / s or more, decreases and increases. The greater the stiffness of ina inlet bearing, the lower the sound pressure level of the whole runway.

Such radial clearance is too small, the total sound pressure level of angular contact ball bearing is reduced, and the radial clearance is greatly increased with the main frequency. Control raceway sound: a small carefully selected service condition of optional low-noise bearing pulsation method. Resway often affects the noise of the whole machinery, and the noise reducer drum can reduce the general noise.

(2) Ball and control ball bearings or bearings with pure radial load are affected by large-scale listening mode.

During low-speed operation, due to the driving of centrifugal force, rolling in non-small area load will be affected by cage or raceway and noise. However, with the increase of speed, the noise will disappear. The impact on the method to control its working capital includes: appropriately reducing radial clearance and using a rational junction The mechanism is the flexibility of ina imported bearing cage.

(3) Bearing discordant noise and sound control of shock bearing,

ina imported bearing, his every harsh metal friction opportunity is mainly in fat lubricated bearing in larger model, while oil based on degradation performance is more prone to grease in any lubricating oil. In addition, it is more likely to occur in winter, when pure radial load, radial clearance and special occasions are vulnerable Damage, and at a specific speed, the size of different models is high, two will also produce continuous intermittence.

Outer ring raceway specific treatment methods to prevent discordant sound. If any, you can choose this ina imported bearing, or appropriately reduce the internal clearance of the bearing, excellent performance and bearing grease and matching part to improve the rigidity.
