HRB bearing small make up to introduce angular contact ball bearing raceway noise analysis

There is rotational, have HRB bearing ( ) Jiaxing bearing group sales co. , LTD. ( The company) Is bearing group co. , LTD. Established in jiaxing spot sales window, specializing in HRB brand bearings, facing the whole country, the existing stock 50 million yuan, covers the whole bearing, have very strong spot supply, is the group's retail sales center. Raceway is due to the angular contact ball bearing rotates roller rolling in the race 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, the high quality 6203 angular contact ball bearing raceway is 25 ~ 27 db. This noise to bear radial load of single row deep groove ball, angular contact ball bearing is the most typical it has the following characteristics: a. Randomness of noise and vibration; b。 The vibration frequency above 1 KHZ; c。 No matter how the speed of change, 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. Angular contact ball bearing stiffness increases, the lower the total sound pressure level, even if the speed increases, the total sound pressure level increases; f。 Lubricant viscosity is higher, 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. As is known to all, even if is to use the contemporary most advanced manufacturing technology and processing angular contact ball bearing parts, there will always be the working surface of varying degrees of tiny geometric error, thus make the raceway and rolling body produces slight fluctuations inherent vibration excitation vibration system. Although angular contact ball bearing raceway noise is inevitable, but can take work surface precision machining parts, choose right angular contact ball bearing and precise use angular contact ball bearing makes the noise reduction of vibration reduction.
