NTN bearing oil using the environment of the main reasons of temperature rise

Want to make sure that NTN bearing life is longer, then from the surface to prepare more, including to the oilless bearing installation and use of the environment, regular maintenance and check if all correct, and should have a special personnel in charge. Believe everyone is just above said is not clear to the requirement of using the environment, the other should be more or less understand, so today we mainly use the importance of environment for bearing. Grasping the oilless bearing in the use of machinery parts and conditions of use and the environment condition is the precondition of choice suitable for NTN bearing. , need to get data and information on the following aspects: ( 1) Mechanism of function and structure, 2) The use of bearing parts ( 3) Bearing load ( Size, direction) ( 4) Rotation speed, 5) Vibration, shock, 6) Bearing temperature ( The surrounding temperature, temperature) ( 7) The surrounding atmosphere ( Corrosion, clean, lubricate) The choice of the ways of NTN bearing configuration, shaft is usually two bearings in the radial and axial support, at this point, called the oilless bearing on one side of the fixed side bearing, it bear radial and axial load, the fixed axis and the relative axial displacement between the bearing box. When NTN bearing temperature, first of all determine whether false action, such as really rise, should do the following treatment: ( 1) 。 Check the cooling water pressure, water flow and pipeline system is normal. If water is likely to be lower filter blockage, cannot be handled in a timely manner, to stop treatment, when confirm can work, then put into use. ( 2) 。 Should be to check if the governor oil pressure, oil pressure is low can lead to cooling water hydraulic valve closed. ( 3) 。 Check whether oil-free bearings have different sounds, and whether there are abnormal detection NTN bearing swing. ( 4) 。 Take oil whether there is a change of color, sample observation and test to see whether metamorphism. If confirm the degradation new oil should be replaced downtime. ( 5) 。 Check the oil standard oil level is normal, if abnormal, check that the sump oil discharge valve is shut. If the matter, should fill oil, if is the sealant mat permeability oil, should stop processing. When we are in the use of NTN import bearings, if it is found that the temperature is very high, is to stop the equipment running, and find out its reason, and provide solution for processing according to the above, but may be because of the oilless bearing heating for different reasons, so the solution is also different, so still have to treat, particular case is particular completed with the help of the technical staff.
