Thrust ball bearing installation ends, in order to check to see if the installation correctly, must carry on the running inspection. Small mechanical can use hand rotation, to confirm whe ther smooth rotation. Check the project has for foreign body, scars and indentation caused to seize up, because install bad, installation seat processing bad and produce torque is not stable, due to clearance is too small, installation error, seal friction caused by the excessive torque and so on. If no abnormality can start power operation.
Large machinery can t manual rotation, so light started immediately cut off power, mechanical idle, check for vibration, noise, rotating parts have contact and so on, make sure no abnormalities, into the power operation.bearing roller bearings
Power operation, from light slow start, slowly to improve set conditions of rated operation. Test running check events, whether to have abnormal sound, bearing the variation of the temperature, lubricant leakage or color, etc. If abnormal, shall be immediately suspend operation, check the mechanical, when necessary, to rem ove the bearing inspection.
Thrust ball bearing temperature, can generally be according to bearing external temperature speculation. But using oil hole direct measurement of the temperature of bearing ring more accurate. Bearing temperature, from the operation began to gradually raised, usually 1 ~ 2 hours after the temperature stability. If the bearing installation is bad, the temperature will rise sharply, abnormal high temperature. Its reason such as lubricant too much, bearing clearance is too small, installation and undesirable, seal friction too. High speed rotating occasions, bearing structure, the choice of the ways of lubrication error to wait also is the reason.abec 9 bearings
Thrust ball bearing rotation tone with stethoscope and inspection, a strong metal noise, different sound, such as irregular sound that anomaly. The reasons are as bad lubrication, shaft or bearing accuracy bad, bearin g damage, foreign bodies, intrusion etc.
Check the bearing don t let the bearing exposure to pollutants or moisture environment. If work interrupt, should with oil paper/plastic film or similar material overlying had machine. If in the don t remove and may carry out the inspection situation cleaning exposed bearing, want to be coated with brush with oil solvent cleaning, again with a lint-free cloth dry or use compressed air blow dry (be careful not to let the bearing component starting rotation). To a small mirror and similar dentists use of that kind of probe to check bearing the orbit plane, maintainer and beads. Do not clean encryption cap or dust bearing; Just wipe its external surface can. If the bearing is damaged situations that need to replace it. In the regular shutdown maintenance period change bearing than due to the array bearing damage the selected into sudden shutdown losses more more economical.bearing manufacturer
Lubricant is very important to bearing is not only, but for all the thrust ball bearing. But please note that Japan bearing shoulds not be add too much grease. And then change bearing the lubricant. Use oil lubrication bearing in reducing for used engine oil, if can of words, should go into fresh oil and let the machine in low speed rotation for a few minutes. As far as possible oil collecting residual pollutant, and then purging except the oil. And the use of grease lubrication bearing in the replacement grease, the use of Joe except apparatus should avoid contact with cotton objects to any part of the bearing. Because these residues of fiber may wedge in rolling piece and between damage, especially the application of bearing more need to pay attention to this problem.
Not only thrust ball bearing workpiece surface quality bad, and the resistance to crystal asked corrosion performance decline. When the thrust ball bearing workpiece serious overheating caused grain bulky, also make in steel and iron chain mass increase, easy to cause the hot working performance deterioration.
