设备开动后,各部位的滚动轴承发出各种正常和异常声音。异常声音表明滚动轴承出现故障先兆或是故障已经发生。通过对滚动轴承各种声响的分析判断,可及时发现并排除各种故障,保障设备正常运转。 滚动轴承工作状态正常时的运转平稳、轻快,无阻滞现象,发出声音和谐,无杂音,表现为“哗哗”的声音,均匀连续而无间断。 若有下列声音时,则为异常声响。 “咝咝”的声音,是轴承内加脂量不够,润滑不良; “咝咝沙沙”的声音,是设备停机时间过长,或轴承径向间隙过小;
After the device is started, all parts of the rolling bearing issue a variety of normal and abnormal sound. Abnormal sound that rolling bearing failure or a fault has occurred. Through the analysis of all kinds of sound analysis of rolling bearings can be found in time and eliminate all kinds of faults, to ensure the normal operation of equipment. Rolling bearing work in normal conditions smooth, light, non-blocking phenomenon, issued a harmonious voice, no noise, the performance of “rushing” sound, even without interruption. If there is the following sound, it is abnormal sound. “咝 咝” sound is the amount of grease in the bearing is not enough, poor lubrication; “咝 咝 rustling” sound is the equipment downtime is too long, or bearing radial clearance is too small;
