Deep groove ball bearing structure damage what problem?

Deep groove ball bearing structure damage what problem? Source: bearing | last updated: - 2020 08 - 07 deep groove ball bearing structure damage what problem? From the deep groove ball bearing damage analysis, found that the structure of the following problems: 1, the seal has a problem. In particular, there are part of the shaft end need lubricants, when lubricant PH value is less than 6, bearing will soon be corrosion, the ball can't normal running and eventually lead to deep groove ball bearing rust and ran inside and outside the circle, serious when glue ontology, spindle all scrap. 2, the problem of deep groove ball bearing axial force. Except for lubricants invade the corrosion damage, the bearing will appear 'apart' phenomenon, namely the ball bearings from the 'basket' scattered to the roller, the plate cylinder and rubber roller, rubber and other surface severely damaged. General solutions are: modified adhesive ontology, set up reliable sealing structure, in order to prevent the lubricant in the bearing. Adjust the deep groove ball bearings, bearing has the correct clearance and axial force, avoid mechanical damage caused by bearing loose. How to check whether the metamorphic 1 deep groove ball bearing grease. Illumination method on a clear day, use a screwdriver to lubricating oil lifted, and horizontal Angle of 45 degrees. Contrast sunshine, observe the oil situation, under the light, can see clearly without wear debris in lubricating oil is good, can continue to function, if excessive wear debris, lubricating oil should be changed. 2. Oil droplets trace method take a clean white paper, number of oil drops on the filter paper, after waiting for lubricating oil leakage, if the surface is black powder, touch resistance acerbity feeling, is the lubricant inside has many impurities, good oil powder, with the hand feels dry, smooth, and yellow. 3. Take oil flow observation two cups, one of which need to be checked out of the lubricating oil, empty on the desktop, the other will leave the measuring cup with lubricating oil for high 30 - desktop 40 cm and tilt, let oil flow slowly to the empty cup, to observe the flow situation, good quality lubricant oil flow should be long and thin, uniform, continuous, if appear oil flow fast and slow, and sometimes has a large flow, the said lubricating oil has deteriorated. 4. Hand twist to lubricating oil twist between thumb and forefinger grinding repeatedly, good lubricating oil hand feel less lubricity, wear debris, no friction, if feel fingers between the larger friction feeling such as sand, suggests that the impurity, lubricating oil can no longer use, a new lubricating oil should be replaced.
