TIMKEN bearing import operation should be regular service points

1, best to lubricating grease lubrication TIMKEN bearing import is in the plan of equipment downtime during implementation, and added on a regular basis, at the same time, the old rid grease or via the drain the old oil out empty. Before adding fresh grease injection nozzle should be wiped clean. If there is no zerk bearing box, should open the bearing box cover or end cover, in order to remove the old grease, clean up after, supplement the same type of fresh oil. 2, lubricating oil, check the oil level of lubricating oil and the oil, in general, a normal oil level equipment oil level Windows or mark a third - Two-thirds of the range. Oil compensating way for oil cup, the display of the oil level represents oil compensating ability, and the bearing box oil level is to meet operation requirements, oil cup CPC a lower than a quarter of its total volume filling oil may be considered. Check and repair method oil, remove a small amount of oil as a sample and fresh oil, has the ability to unit may be considered for oil testing, to ensure the oil qualified. If the sample looks like clouds, so may be mixed with water as a result, people often say that oil emulsification, at this time should replace the lubricating oil. If the sample cheng dark color or thick, then may say lubricating oil has begun to carbonization, should be replaced the old oil thoroughly. If possible, use fresh oil to wash oil. Oil change, should ensure that the replacement with new and old the same type of lubricating oil, adding the meet the requirements of oil level. Use of the lubrication system of oil bath type, if the oil temperature 60 ℃ ( 140°F） The following, and no pollution of lubricating oil, the replacement of a lubricating oil a year. If the oil temperature at 60 100℃（ 140 - 210°F) Need to change four times a year, the lubricating oil. If the oil temperature at 100 - 120℃（ 210 - 250°F) , you need to be replaced every month lubricating oil. If the oil temperature at 120 ℃ ( 250°F) Above, the need to replace a weekly lubricating oil. The correct installation and maintenance is an important factor for normal operation of bearing, at the same time, must pay attention to maintain the purity of the bearing. Bearings must prevent polluted by contaminants and moisture, must have a correct installation and lubrication. In addition, the design of the bearing arrangement, the condition of the oil seal, the form of a lubricant and change cycle and special maintenance also play an important role, must be attention. 1, small mechanical can rotate with the hand, to confirm whether to rotate smoothly. Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on. If there is no abnormal can start power operation. 2, large machines cannot manual rotation, so after no-load start immediately cut off the power, machine idle, check whether there is presence of vibration, noise, rotating parts contact, etc. , confirmed after no abnormalities, into power operation. Dynamic operation, from the beginning of the no-load speed, slowly up to the rated operating conditions. Test run to check the items, whether there is abnormal sound, TIMKEN imports bearing temperature changes, lubricant leakage or discoloration, and so on. If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection. Bearing temperature, average according to the external temperature of the bearing. But using the oil hole directly measuring the temperature of the bearing outer ring more accurate. The bearing temperature, starting operation gradually increases, usually 1 ~ 2 hours after the temperature stability. If the bearing installation, the temperature will rise sharply, abnormal high temperature. The reason such as lubricant, bearing clearance is too small, too much bad installation, excessive friction sealing device, etc. High-speed rotation, imported bearing structure, selection of lubrication method error is also the reason. TIMKEN bearing import examination such as the rotation of the sound with a stethoscope, a strong metal noise, such as vision, irregular note that exception. Its reason has poor lubrication, shaft or precision bearing, bearing damage, foreign body intrusion, etc.
