Self-aligning roller bearing lubrication method

Bearing - Comfortable and durable - Self-aligning roller bearing electricity department author July 20 for your explanation: self-aligning roller bearing lubrication method ( 1) Oil bath lubrication oil bath lubrication is widespread use of low or medium speed oil level should be in the center of the oil level of the lowest rolling element. Want to provide a kind of vision, so you can keep the proper oil level ( 2) Drip drip lubrication bearing lubricants widely used Yu Xiaoqiu running speed is relatively high, the oil is stored in the visible oiler. Oil drop rate is controlled by the top of the screw. （ 3) Splash lubrication with the lubrication method, the oil spill to the upper bearing by the rotation of the gear or simple dish installed near the bearing, without bearing submerged in oil. It is usually used for auto transmission and final drive gears. The method is used for speed reducer. （ 4) Circulation lubrication cycle are normally used for high speed running need lubricating bearing cooling and used at high temperature of bearing. Oil supply by on the right side of the pipe through the bearing, through the drainage pipe on the left. After cooling in the reservoir, through the pump and filter returns the spherical roller bearings. Oil drain should be greater than oil duct such excess oil no backup housing. Self-aligning roller bearing lubrication method ( 一) Jet spray lubrication lubrication is typically used for ultra high speed bearing, such as the jet engine bearing d m n valve ( D m: roller pitch diameter mm; N: speed in RPM) More than 1 million. Lubricating oil spray one or more of the nozzle under pressure directly into the bearing. General jet lubrication oil spray, circle, cage guide surface. Under the condition of running at high speed, bearing the air around the rotating oil injection is deflection. Oil from the nozzle jet speed should be more than 20% of the inner ring of the outer circumferential velocity ( And the guide surface of the cage) 。 More uniform cooling and better distribution of temperature for a given is to use more of the nozzle to realize the amount of oil. Oil is compulsory eduction of lubricant can reduce the resistance and oil can be effectively carry heat. （ b） Oil mist lubricating oil mist lubrication, also known as the oil mist lubrication, using spray to the oil mist in the bearing. This method has the following advantages: ( 1) Because you need less oil, the oil mixing small resistance, faster. （ 2) Near the bearing of pollutants slightly less for spills. （ 3) Continuous supply of light oil more easily; Extending the bearing life, therefore, the lubrication method is used for high speed spindle bearing machine, high-speed pump, mill roll neck, etc. ( Figure 12. 9) 。 For large oil mist lubrication of the bearing, bearing recommended counseling. Self-aligning roller bearing lubrication methods: oil/air lubrication method using oil/air lubrication method, a very small amount of oil piston intermittently excrete a constant into a constant flow of compressed air pipe. Oil flow pipeline along the wall and close to constant flow. The main advantage of the oil/air lubrication is: ( 一) Due to the minimum necessary to provide oil, this method is suitable for high speed because the heat generated by the less. （ b） Because of the minimum amount of oil bearing temperature is stable. In addition, because a small amount of oil, there is almost no atmospheric pollution. （ c) Because only the fresh oil is supply bearing, oil deterioration will not need to be considered. （ d） Due to the supply of compressed air has been bearing, high internal pressure, dust, cutting fluid and could not enter. For these reasons, this method is mainly used for the high speed machine tool spindle, etc. Bearing comfortable and durable, )
