On the Reasons for the Ventilator Bearing Noise and its Control

Abstract:

According to the phenomenon that the increasing noise of the ventilator in Longyan Beishan Coal Mine are caused by the bearings, this paper starts analyzing the reasons for the noise of the ventilator bearing, and thinks that the noise is mainly the active noise from the air and noise from the machines which are caused by vibrations. The noise of the ventilator bearing is related to such factors as its size, material, structure design, processing, assembling, loading, and lubrication. So it puts forward that workers should try to choose light, small-sized bearings so as to improve the quality of assembly, adjust the space and apply preloaded force; the workers should strengthen maintenance, use proper lubrication and enhance the monitoring.
