The analysis of ball track noise

The analysis of ball track

In the process of using SKF bearing will often bring all kinds of noise. Today we are going to analyse one uncommon noise: ball track sound

Ball track sound is a kind of stable and successional noise that is made by the circulation of bearing when the ball is rolling in the ball track. People will notice it only when the sound pressure level and express are loud. Actually sound power of the ball track is limited. The sound of high quality 6203 bearing is 25-27dB, The single row deep groove ball bearing has the typical model of this noise. It has the following features:1.noise and vibration are random 2. Vibrating frequency is more than 1khz 3.No matter how rotating speed changes, the main frequence of noise almost is invariant,but the sound pressure level raise along with the increase of the rotating speed.4. when the radial backlash is increasing, the sound pressure level is increasing too. 5. the hardness of the bearing block is high, the total sound pressure level is low, even the speed is increased, the sound pressure level will be controled at low level. 6.the viscosity of lubricant is high, the sound pressure level is low. For grease, its viscosity and the shapes and sizes of curd fibres can influce the noise

The ball track sound generate from the vibration of the ferrule which is under load. And the stretch contact between furrule and ball construct nonlinearity vibration system. when the lubrication or the  process accuracy are low will excite the natural vibration which relate to the stretch features, becoming noise in the air. As we all know, Even if has used the contemporary most excellent technique to process the bearing part. Its running surface generally has all kinds of the small geometrical error, thus causes the ball track and the rolling body has the small fluctuation which stimulates vibrating system natural oscillation.

Although the noise of the NSK bearing is inevitable,  However may adopt the precision  components working surfact, selects the bearing correctly and precisely uses the bearing to reduce its noise.
