GEZ-ES-2RS Radial Spherical Plain Bearings Features

The raceway noise of spherical plain bearing is a kind of steady and continuous noise which is excited by the rolling of the rolling body in the raceway when the bearing rotates.In fact, the sound energy excited by raceway sound is limited. For example, under normal circumstances, the sound of bearing raceway is 25 ~ 27dB.This noise to bear radial load of single row deep groove ball bearing as the most typical. Randomness of noise and vibration. Vibration frequency above 1 KHZ. No matter how the speed of change, the main noise frequency is almost the same sound pressure level increases with the increase of rotational speed. And when the radial clearance increases, the sound pressure level has increased dramatically. Bearing stiffness increases, the lower the total sound pressure level, even if the speed increases, the total sound pressure level increases. 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.

The raceway sound of spherical joint bearing is caused by the inherent vibration of the ring under load.The elastic contact between the ring and the rolling body constitutes a nonlinear vibration system.When the lubrication or machining precision is not high, it will stimulate the inherent vibration related to the elastic characteristics, which will become noise when transferred to the air.Even if the most advanced manufacturing technology is used in the processing of bearing parts, there will always be small geometric errors of different degrees on the working surface, so that there will be small fluctuations between the raceway and the rolling body to stimulate the natural vibration of the vibration system.Although it is inevitable, but it can adopt high precision machining parts working surface, the correct selection of bearings and accurate use of bearings to reduce noise and vibration.
