NSK bearing noise disposal methods in the application

Bearings are installed in the process of the secondary reason is: the emergence of scars NSK bearings are installation, assembly, outer ring and inner ring tilt; Or it is emerging in the process of the installation and assembly of the charge load, ultimate bearing emerging scars. Is installing a bearing do you want to work in accordance with the standard, will not cause many achievements, such as installing a way or method not when, NSK bearings will constitute the raceway surface and bone surface bearing emergence of linear scars. The installation of deep groove ball bearing indirect response when using the fine degree of the bearing, stature and function. Bearing quality and so on various aspects are good match, but the rolling bearing is fine parts, its use should be cautious to stop accordingly. No matter how high performance bearing use, if use undeserved, will not get the desired performance. Using the attention to matters relating to NSK bearings with the following article: ( 1) , adhere to the bearing and the surrounding clean. Even the eyes can't see the little dust, also can bring bad influence to NSK bearing. So, to stick around, clean the dust from invading bearings. ( 2) And watch carefully. Give bearing intense impact in practice, which will produce scar and creasing, become the cause of the accident. Serious situation, can crack and fracture, so must pay attention to. ( 3) , use the appropriate operating tools. To prevent the substitution of existing tools for, it is necessary to use appropriate tools. ( 4) And to pay more attention to the bearing corrosion. NSK bearings operating, hand sweat will become rusty. To pay more attention to operation with clean hands, it is better to try to bring gloves. General speaking, trying to control the noise impact of NSK bearings, essential countermeasures and approaches for the source of the noise ability receive treats the effect. The main way is: ( 1) Choose low noise cylindrical roller bearings; ( 2) To prevent resonance with the host attack, sensitive to avoid the resonance speed; ( 3) Try to eliminate the noise from the cylindrical roller bearing application link; ( 4) When other methods fail, sound insulation and noise elimination of additional measures. NSK bearings when temperature increases, the first criterion whether misoperation, as does increase, should do the following treatment: check the cooling water pressure, water flow and pipeline system can be normal. If water is likely to be lower filter infarction, not timely, you stop disposal, when confirm can work, then put into use. Check the governor oil pressure, if the low oil pressure can cause cooling water hydraulic valve closed. Check the NSK bearings can have different sounds, and detection of cylindrical roller bearing degrees whether there are abnormal. Can take oil sample check color have change, look whether metamorphosis and stop the test. If confirm the degradation, should stop to change a new oil. Can check the oil standard oil level is normal, if abnormal, check the tank oil discharge valve will shut. If have shut, should fill oil, if be the sealing rubber gasket of oil leakage, should stop the treatment.
