Nc state of lubrication method used by the car to know? Release date: 2020 01 - 06 clicks: 241 times in the process of the nc vertical lathe maintenance to keep the lathe work and reduce the wear and tear, must often to lubrication friction all parts of the lathe. Set car lubrication way we commonly used have the following kinds: 1. Lubrication by hand by hand to add lubricating oil or grease to friction parts, used for light load, low speed of friction pair or intermittent work. Such as the common machine tool guideway, hanging wheel and the roller chain ( Oil lubrication) , the tooth shape chain ( Brush oil lubrication) dn < 0。 6 * * * 10 of rolling bearing and ball screw pair ( With grease lubrication) And so on. 2. Lubrication oil by dead weight drops into the friction parts, used in small, easy to close to friction pair for quantitative oil supply of rolling bearing, sliding bearing is not important ( Peripheral speed < 4 - 5 m/s, light load) , chain, ball screw pair, circumferential speed < 5 m/s plate friction clutch, etc. 3. Wick lubricating oil used in the wick in the capillary action or using rotating shaft form of negative pressure self-priming lubrication, used for medium and low speed gear, need of sliding bearing in a vertical shaft oil is of medium speed, light load on the rolling bearing, etc. 4. Have mat used in oil in the oil lubrication capillary action or using rotating shaft form of negative pressure self-priming lubrication, used for peripheral speed < 4 m/s of the sliding bearing, etc. 5. Imbibition grease used in using rotating shaft form of negative pressure self-priming lubrication, used for peripheral speed> 3 m/s, bearing the intermittent < 0. 01 mm precision vertical lathe spindle bearing. 6. Centrifugal lubrication under the action of centrifugal force, lubricating oil flow continuously to lubricating points along the conical surface, used for loading on the vertical shaft of rolling bearing. 7. Part or all the oil bath lubrication friction surface in lubricating oil, used for medium and low speed friction pair, such as circumferential velocity < 12 - 14 m/s closed gear; Peripheral speed < 10 m/s worm, chains, rolling bearing; Peripheral speed < 12 - 14 m/s sliding bearing; Peripheral speed < 2 m/s plate friction clutch, etc. 8. Ring lubrication through rotating parts from the oil pool, oil or discharge to the lubrication part, used to smooth load, rotation speed is 100 - Sliding bearing of 2000 r/min. 9. Splash lubrication through rotating parts from the oil pool, oil or discharge to the lubrication part, used in closed gear, easily splashed oil bearing, high-speed sliding bearings, roller chain, plate friction clutch, etc. 10. Scraper lubrication through rotating parts from the oil pool, oil or discharge to the lubrication part, used in low speed ( 30 r / min) Sliding bearing. 11. Lubrication of roller rotate parts through from the oil pool, oil or discharge to the lubrication part, used to guide. 12. Spray lubrication with oil pump nozzle into the oil in the high pressure lubrication parts, rolling bearing for high-speed rotation. 13. Manual pump pressure lubrication using manual pump intermittently grease into the friction surface, no longer recycling of used lube oil usually use, to need less oil, gas low frequency of the guide rail, etc. 14. Pressure loop used lubricating oil pump pressure oil to the friction parts, used oil tank return, after cooling, filter used for circulation, used for high speed and overloaded or precision friction pair lubrication, such as rolling bearing, sliding bearing, roller chain and tooth shape chain, etc. 15. Automatic timing quantitative lubrication with oil pump will be lubricating oil pump, and make it through the quantitative valve cycle into the lubrication parts, used for nc machine tools, such as high degree of automation of machine tools on the guide rail, etc. 16. Oil mist lubrication use compressed air to make oil from the nozzle, the atomization and then into the friction surface, and make its precipitation in saturated state, let the thin layer of oil film on friction surface adhesion, lubrication and cooling effect, can greatly reduce the temperature of friction pair. Used in high speed ( Dn < 1 million) , light load of small and medium-sized, high speed rotary rolling bearing of ball screw, tooth shape chain, closed gear, guide rail, etc. Commonly used in an airtight chamber, make the oil mist is not easy to run away.
