Oil lubricated sliding bearing lubrication methods - bearing knowledge

Oil lubricated sliding bearing lubrication is commonly used method is: ( 1) Manual lubrication when found bearing lubricating oil is insufficient, timely with the oiler oil supply, it is the most primitive way. This method is difficult to maintain a certain oil and a greater risk of inadvertently forgotten refueling, usually only used for light load, low speed or intermittent movement of the occasion. The best on the oil-way set dust cover or ball valve, and filter felt, cotton, wool, etc. ( 2) Oil drip lubrication from the container through hole, needles, valve and other supplies roughly quantitative lubricating oil, is the most classic drip oil cup. Drops of oil varies with oil viscosity and bearing clearance and the oil hole position different significant changes. Used for peripheral speed is less than 4 ~ 5 m/s in the light load and load bearing. ( 3) Ring lubrication can only be used for horizontal spindle lubrication method. Depend on the shaft and rotating ring oil pool of lubricants to bearing. Applicable to the diameter of axle is greater than 50 mm medium speed and high speed bearing. Oil ring had better be seamless, bearing width to diameter ratio less than 2, can use only one oil ring, otherwise need two oil ring. ( 4) Wick lubrication by capillary action of wick and siphonage drew the lubricating oil in the oil cup to the bearing, used for peripheral speed is less than 4 ~ 5 m/s in the light load and load bearing. Wick and filtering effect. ( 5) Lubrication oil pad using pad capillary action, the grease to the diameter of axle surface in oil pools. This method can make the friction surface often keep clean, but the dust will plug wool stoma cause insufficient oil supply. Oil pad amount of lubricating oil is only 1/20 of its oil lubrication. ( 6) Oil bath lubrication bearing part of immersed in the lubricating oil lubrication method. This method used in the thrust bearing of vertical shaft, and should not be used for horizontal spindle radial bearing. ( 7) Splash bearing by panting and splash of rotating parts in the fuel tank of lube oil supply bearing, bearing is suitable for high speed. ( 8) Will spray lubrication oil atomizing spray on the surface of the friction, lubrication method, suitable for high speed bearing. ( 9) Pressure lubrication oil supply oil to the bearing lubrication pump pressure, will flow from the bearing lubricating oil recycling into the oil pool to use cycle, is the largest oil, and the most stable lubrication method, suitable for high speed and overloaded, important sliding bearing.
