With sound identification of TIMKEN bearings, bearings of knowledge

The sound device is adopted to the size of the rolling sound of TIMKEN bearings in operation and the quality inspection, TIMKEN bearing even with slight stripping damage, such as would an exception and irregular, and with the sound of the measuring device can distinguish. Listen to use hearing to identify irregular operation is a very common method. For example, with the aid of electronic stethoscope check feel a certain parts of the abnormal noise is often experienced methods used by the operator. If a TIMKEN bearings in good state to swing low whimpering sound. If a sharp hissing sound, make sound, and other irregular often said TIMKEN bearings in adverse to swing. High-pitched squeaky noise may be caused by improper lubrication. Improper TIMKEN bearing clearance can cause metal sound. TIMKEN bearing outer ring orbit of concave dent causes vibration of the orbit, and cause smooth and crisp voice. If because of the installation caused by hitting scar also can produce noise, the noise will be as the TIMKEN bearing rotating speed of high and low. If there are intermittent noise, rolling parts may be damaged. This voice is happens when the damaged surface is rolled out, TIMKEN bearings if pollutants often causes hissing sound. Serious with bearing damage can produce irregular and big noise. Can borrow TIMKEN bearing damage is by listening to sleep, but usually at this time has come to TIMKEN bearing must be replaced immediately. Therefore, good methods such as using techniques such as electronic condition monitoring instrument. Compared with old method USES a stick more precise forecast TIMKEN bearing condition.
