Smooth fat NSK tapered roller bearing used in the importance of maintenance

Removed in order to distinguish the NSK tapered roller bearing whether can use, check after wash bearing. Examination of raceway surface, rolling surface, cooperate with the abrasion of the state, adhere to the rack, the increase of the bearing clearance and has nothing to do with dimension precision landing damage, abnormal. The small ball bearing type respectively, then the inner ring with one hand support level, rotate the outer ring can confirm fluently. Bearing maintenance: bearing cleaning: removing NSK tapered roller bearing under repair, the appearance of the first recorded bearing, confirm the residual stock of lubricant, sampling inspection with lubricant, bearing. Common use gasoline, kerosene as a cleaning agent. Is bearing industry, using the kind of smooth fat quantity biggest bearing in high speed wire-rod mill, accounts for about 70% points with the amount of fat. Because that kind of smooth fat chose fiber and delicate, white light to filter of lithium do thickener, application of mineral oil as base oil, the very light is difficult to know the foot to low bearing reduce the vibration value of the request. Another benefit is no bad good pumping, whether mechanical fatliquoring, is still the manual besmear butter, tough is contracted. The price is low, and the smooth fat NSK tapered roller bearing can be greatly reduced. However, due to the application of mineral base oil, make the kind of smooth fat is rust removal and rust on the function of some physical and chemical purpose to play close button. Such as bearing life can reach 200 hours, linear guide to common problems. Starting and running torque is - 20 ℃ test when there is no problem. The smooth fat application at ordinary temperatures - 20 ~ 120 ℃, when is above 150 ℃ high temperature applications, basic oil evaporation too fast, will flow out serious phenomenon, such as bearing application life shortens greatly. 1. Oil bath lubrication oil bath lubrication of the bearing is a bearing in the ordinary way of lubrication, suitable for low, medium speed, bearing lubrication. NSK tapered roller bearing part will be immersed in the tank, the lubricating oil by the bearing parts of rotation, and then flow back to the oil level of oil tank should be slightly lower than the lowest in the middle of the roller. 2. Bearing lubrication drops of oil lubrication is suitable for need to ration oil to NSK tapered roller bearing parts, drops of oil every 3 - individually A drop of it is advisable to 8 seconds, too much oil will make bearing temperature increased. 3. Circulating oil lubrication of the bearing with oil pump will be filtered oil walks to the bearing parts, after NSK tapered roller bearing lubricating oil filter cooling after use. Because circulating oil can take away heat, must make the bearing cooling, therefore method is suitable for high speed bearing parts. 4. Air spray lubrication of the bearing with the monotony of contraction after the sprayer and lubricating oil mixed form oil mist, radial bearings, can effectively make the bearing cooling airflow and can prevent the intrusion. This method is suitable for high speed and low temperature lubrication bearing parts. 5. Radiation lubrication bearing with oil pump will shoot the oil in the low pressure of nozzle to the NSK tapered roller bearing, into the bearing of the bearing at the other end into the oil in the tank. When bearing at high speed, rolling body and maintain frame with commensurate high rotate speed makes the surrounding air, the air in separate lubrication way is difficult to be sent to the bearing lubricating oil, the necessary spray lubricating oil with low radiation to bearing, the position of the nozzle should be placed in the middle of the inner ring and maintain frame between.
