Bearing in operation process, in order to provide better performance, generally using grease lubricated bearings, bearing operation can decrease the friction degree and temperature, if the grease is bad, not only plays the role of relevant, using instead of bearing more unfavorable, so we must buy grease to learn how to identify the grease has changed.
Judge the method of lubricating grease metamorphism:
1, oil flow observation method
Take two cups, one Sheng to be oil check, another empty on the table will be filled with lubricating oil cup held high 30-40 cm away from the desktop and tilt, let oil flow slowly onto the empty cup, to observe the flow of lubricating oil, good quality flow should be slender even if without stop, oil flow unsteadiness and large flow, said lubricating oil has deteriorated.
2. Hand twisting
The lubricating oil is rubbed repeatedly between the thumb and index finger. The better lubricants feel lubricity, wear debris and no friction. If they feel the larger friction between the fingers, it indicates that there are more impurities in the lubricating oil and they can't be used again. New lubricants should be replaced.
3. Light method
On a sunny day, use a screwdriver to lubricating oil lifted, and the horizontal plane form an angle of 45 degrees. In contrast to sunlight, we observe the oil droplet situation. Under the light, we can see clearly that no debris in lubricating oil is good and can continue to function. If there is too much debris, lubricating oil should be changed.
4, oil drop trace method
Take a clean white filter paper, drop a few drops of oil in the filter paper, after the oil leakage, if the surface is black powder, touch resistance is acerbity, lubricating oil there are many impurities, good oil with no powder, dry and smooth to touch, and yellow mark.
