1. The bearing raceway and the sound control method are INA bearings during operation. On a continuously rolling sliding surface, there are printed distinctive ball foundations. In other words, the overall sound of the roller bearing with other sounds. The ball rolls irregularly, above the frequency of 1000Hz, it will not change the main frequency of the speed change, but the overall speed rapidly increases the sound pressure level.

It affects the raceway. The sound pressure level of the raceway is increased by decreasing the viscosity. For a small roller bearing, the sound pressure level of the medium viscosity increase is soundly related to 20 square millimeters/second or more, decreasing and increasing. The greater the INA bearing stiffness, the lower the sound pressure level of the entire runway. If the radial clearance is too small, the total sound pressure level of the angular contact ball bearing and the reduction of the main frequency will greatly increase the radial clearance. Control of raceway sound: a small selection of carefully selected conditions for use with low-noise bearing pulsation methods.


2. The pure radial load of ball and control ball bearings or bearings is influenced by the large listening mode. At low speeds, due to the centrifugal force driving on a non-small area load rolling will affect the cage or raceway and noise. However, as the speed increases, the noise will disappear.

The impact on the method to control its working capital includes: appropriately reducing the radial clearance, using a rational structure is the flexibility of the INA bearing cage.


3. Bearing discordant noise and sound-controlled shock bearings, INA bearings each of his harsh metal friction opportunities, mainly in fat-lubricated bearings in larger models, while oil based on degradation performance is more likely to appear Grease, in any lubricant.
