Bearing rolling sound check maintenance care

The sound device is adopted to the size of the rolling sound and sound quality of bearing in operation to stop check, bearing even with slight stripping damage, also an exception and irregular, and with the sound of the measuring device can distinguish. Application of hearing to identify irregular operation is a very common way. For example, with the aid of electronic stethoscope check feel a certain parts of the abnormal noise is often have experienced operators use solution. If the bearing in good state to swing low whimpering sound. If a sharp hissing sound, make sound, and other irregular often said bearing in adverse to swing. Sharp make noise may be caused by inappropriate smooth. Inappropriate bearing clearance will form metallic sound. Bearing outer ring sunken orbit of dents on the tracks will make up the vibration, and form a smooth loud voice. If the device is formed by the striking scar also can produce noise, the noise will be different with bearing speed up and down. If there are intermittent noise, rolling parts may be damaged. When the sound is attack damage appearance is rolling out of date and bearing inner if pollutants often provoked hissing sound. Serious with bearing damage can produce irregular and big noise. A, bearing cleaning rough washing and fine washing stop, bearing and the metal frame can be put in use at the bottom of the container. B, coarse, with a brush in oil and other things clear smooth fat or adhesive. If at this time in oil bearing, pay attention to due to foreign bodies such as damage to the rolling surface. C, fine cleaning, turn gradually in the oil bearing, must stop seriously. Usually use detergent for neutral aqueous diesel or kerosene, according to the demand is also sometimes used warm lye, etc. No matter use which kinds of detergent, often should filter stick to clean. After cleaning, coating anticorrosive oil or antirust grease on the bearing immediately. 2, checking and judging: in order to distinguish with the statue bearing whether to apply, bearing to inspect the dimension precision, rotating accuracy, internal clearance and the matching surface, raceway surface, adhere to the rack and seal rings etc. About the result that can be used by bearing or knowledge of bearing stop judging. Bearing discriminant standard according to the mechanical properties and important degree and inspection cycle. If you have the following injury, bearing not to use, must change. A fracture and defect of bearing parts. B raceway surface material on the surface of the rolling strip.
