In high speed, high temperature conditions, NSK bearings has grease lubrication of import not timely lubricating oil can be used. Through the cycle of lubricating oil, can take a lot of heat. Viscosity is an important characteristic of lubricating oil, the size of the viscosity of oil directly influence the liquidity and formed between the friction surface of the oil film thickness, bearing operating temperature lubricant viscosity is generally 12-15 CST. The GaoYingXuan speed low viscosity, the more heavy load rappel/abseil stations should be higher viscosity. Commonly used lubricating oil have JiXieYou, high speed JiXieYou, turbine oil, compression oil, transformer oil, cylinder oil etc.
Oil lubrication methods include:
1. The drops of oil lubrication
Drops of oil lubrication is suitable for the need to supply quantitative NSK bearings components to import oil, drop the amount of oil every 3 to 8 seconds general a advisable, too much oil amount will cause bearing temperature increased.
2 circulating oil lubrication
Be filtered with oil pump oil conveying to bearing parts, through the NSK bearings imported oil filter again after cooling after use. Due to circulation oil can take away a certain quantity of heat, make bearing cooling, reason this law is applicable to the high speed bearings components.
3. Oil bath lubrication
Oil bath lubrication is the most common lubrication method, suitable for low, medium speed NSK bearings imported the lubrication, bearing part of the dip in the slot, by rotating bearing parts lubricant with on, and then come back to the oil tank face should be slightly lower than the minimum of the roller center.
4. Jet lubrication
With oil pump will be high pressure oil through the nozzle to shoot to bearing, NSK bearings imported into the oil in the other end into the oil bearing. In bearing high speed rotating, rolling body and maintains a also with very high rotation speed around to air form air, using general lubrication methods, it is hard to lubricating oil to bearing, then must use the method of high pressure jet will lubricating oil spray to bearing, nozzle should be put in the position of the inner circle and maintains a center between.
5. Spray lubrication
The compressed air with dry by spray and lubricating oil mix formation oil mist, jet bearing, the air can effectively make bearing cooling and prevent the impurities invasion. This method is suitable for high speed, high temperature NSK bearing parts imported lubrication.
