Jiaxing bearing, bearing raceway noise related knowledge

Jiaxing bearing group sales co. , LTD. , is the spot sales center of jiaxing bearing factory, specializing in HRB bearings, application in production design and related machinery has a wealth of technical experience, today we are together and we learn the bearing raceway noise related knowledge. Roll bearing raceway noise, noise is due to the rolling element bearing rotates in raceway rolling and inspire a smooth and continuous noise, only when the sound pressure level or tone great concern. Actually raceway sparked by the sound of sound energy is limited, such as in normal circumstances, quality of 6203 bearing raceway is 25 ~ 27 db. This noise to bear radial load of single row deep groove ball bearing is the most typical, it has the following features: a, randomness of noise and vibration; B, vibration frequency above 1 KHZ; C, no matter how change speed, the main frequency noise almost unchanged while the sound pressure level increase with the increase of rotational speed; D, when the radial clearance increases, the sound pressure level increased dramatically; E and bearing rigidity increases, the lower the total sound pressure level, even if the speed increases, the total sound pressure level increases; F, the higher the viscosity of lubricant, the lower the sound pressure level, but for grease lubrication, the viscosity, the shape of soap fiber size can influence the noise value. Raceway acoustic source lies in the inherent vibration caused by ring after exposure to the load. Because of the ring and rolling body elastic contact nonlinear vibration system. When lubrication or the machining accuracy is not high will stimulate the related to the elastic characteristics of natural vibration and passed to the was noise in the air. Despite the rolling bearing noise is unavoidable, but can take work surface precision machining parts, the correct selection of bearing and precise use of bearing noise vibration reduction.
