How to use the oil - bearing knowledge

1. Manual oil for equipment used by operators to lubricating oil pot or oil gun point oil hole, nozzle and oil cup refueling called manual for oil lubrication, mainly used in low speed, light load and sliding surfaces of a batch job, open gears, chains and other single friction pair. Controlled amount to rely on workers feel and experience. 2. Oil drip lubrication oil drip lubrication primarily use oil cup to the lubrication oil supply. Commonly used oil cup: needle valve type oil cup, pressure drops of oil oil cup, etc. Oil cup made multi-purpose light metals such as aluminum or aluminum alloy frame, glass inspection hole use transparent plastic or glass, in order to observe its internal oil level. 1) Needle valve type oil cup of the oil cup of the drops of oil is controlled by the needle valve, oil cup CPC an impact can be directly through the needle valve annular clearance of drops of oil. 2) Pressure drops of oil cup of the oil cup bottom have a needle valve, the valve stem through the operating cylinder oil cup out of external connection adjusting nut. Valve has closed by piston compressor exhaust through the spring pressure control, and can be used on the stem nut to regulate the amount of oil drip oil cup. 3) Jump pin type lubricating oil cup of the lubricating oil cup directly on the friction pair, generally by friction pair slight vertical vibration pump, set oil hole to jump needle drop and the lubrication friction pair. 4) The thermal oil cup this oil cups controlled by the temperature change of the friction pair. Temperature of friction pair by oil cup metal pipe to the oil cup of the air cavity on the expansion or contraction. When the air expands, oil cup inside the cavity pressure increases above, forcing a small amount of lubricating oil outflow oil cup into the friction pair; And in the air shrinkage, flow stops, so continuous action. The oil cup on some requirements go before starting friction pair cannot be applied. 5) Continuous pressure oil cup of the continuous oil cup because of the oil reservoir can remain unchanged under the oil pressure, so can ensure uniform automatic oil supply. 6) Uniform drip oil cup lube oil reservoir from above after even on the floating valve, added the following oil reservoir, the volume of oil to the friction pair to adjust by the needle valve. 7) Piston type oil cup of the drops of oil can leverage to adjust on the cup. 3. Wick and oil lubrication oil and wick MATS lubrication method is the wick, felt pad soaked in oil, application of siphon and capillary effect of oil absorption. The viscosity of the used oil should be lower. Oil and wick mat and so on has certain filtering effect, can keep the oil clean. Pad is commonly applied to gas lubrication difficulties or close to the bearing not easily, but by the velocity of the surface of the lubrication is unfavorable and exorbitant. Oil pad from dedicated sucked into lubricating oil in storage tank by the journal of supply in contact with it. Pad mainly used thick carpet manufacturing, when using, should be regular cleaning and drying, and then reassemble use. 4. Oil ring or oil chain lubrication oil rings or oil chain lubrication can only be used for horizontal axis, a ring is hanged on the shaft, the lower part of the ring in oil pool and the use of the friction shaft rotates, the oil ring spinning, lubricating oil to shaft neck, again on the surface of shaft neck diffusing into all lubricating points. Need to pay attention to axis should be no impact vibration, speed too high. 5. Oil bath and splash lubrication oil bath and splash lubrication is mainly used for closed gear, chain and internal combustion engine, etc. General use high-speed ( 5 m/s) Rotating parts from specially designed near the oil pool of oil to lubricating points. Sometimes in the shaft set with oil the wheels of the oil to the journal. Splash lubrication oil pool should be installed by oil, the oil level of oil pool depth should maintain a minimum with a round of submerged 2 ~ 3 depth. In order to facilitate heat dissipation, had better be in airtight gear box set on vent to strengthen case inside and outside air convection. 6. Pressure forced lubrication forced lubrication is inside the equipment set up small lubrication pump through the drive and motor drive, lubricating oil from the oil pool to lubricating points. Oil supply is intermittent, it can be used as a separate lubrication, also can be a few together lubrication pump. Forced lubrication, the lubricant with equipment of open and stop automatically send, stop. By adjusting the oil flow by the plunger stroke, by a few drops to a few minutes 1 drop per second. 1 ~ 4 mpa. To maintain the cleanness of lubricating oil, the oil pool should have certain depth, in order to prevent the inhalation of oil pool in the sediment. 7. Oil lubrication oil lubrication refers to the lubricating oil mixed with a certain pressure of compressed air in the injection valve after injection to the lubrication point of lubrication. On gear lubrication requirements under direct pressure send lubricating oil from the meshes into direction of gear tooth meshing backlash for lubrication. Of two-way rotating gear, the need to both sides of the gear are installed injection pipe. In worm gear drive, the injection should be started with the worm helical worm gear meshing side jet.
