Control of KOYO cylindrical roller bearing noise processing method

In general, to control noise impact of KOYO bearing, it must take countermeasures in view of the source of the noise, and to receive the cure effect. The main way is: ( 1) Choose low noise cylindrical roller bearings; ( 2) Sensitive to avoid resonance with the host, to avoid the resonance speed; ( 3) Try to eliminate noise from the cylindrical roller bearing application link; ( 4) In the other method is invalid, sound insulation and noise elimination of additional measures. When KOYO bearing temperature, first determines whether the misoperation, as did rise, should do the following: check the cooling water pressure, water flow and pipeline system is normal. If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. Should be to check if the governor oil pressure, oil pressure is low can lead to cooling water hydraulic valve closed. To check whether there is sound, KOYO bearings and detection of cylindrical roller bearing place whether there are abnormal. Take oil whether there is a change of color, sample observation and test to see whether metamorphism. If confirm the degradation new oil should be replaced downtime. Check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut. If the matter, should fill oil, if is the sealant mat permeability oil, should stop processing.
