Cov khoom tseem ceeb ntawm txhua yam ntawm elevator yog qhov sib txawv, tab sis lawv feem ntau muaj yim ntu: traction system, kev taw qhia system, tsheb, qhov rooj kaw lus, qhov hnyav sib npaug, hluav taws xob rub lub cev, hluav taws xob tswj qhov system, kev tiv thaiv kev nyab xeeb.
Of elevator tau muab faib ua ob pawg: elevators thiab escalators.Cov khoom tseem ceeb ntawm txhua yam ntawm elevator yog qhov sib txawv, tab sis lawv feem ntau muaj yim ntu: traction system, kev taw qhia system, tsheb, qhov rooj kaw lus, qhov hnyav sib npaug, hluav taws xob rub lub cev, hluav taws xob tswj qhov system, kev tiv thaiv kev nyab xeeb.Feem ntau ntawm lub elevator lub ntsiab cov cav tov yog nyob rau saum toj, nrog rau lub cev muaj zog thiab tswj system.Lub cev muaj zog yog tig los ntawm lub iav los yog (thiab) rub, raws li lub chassis thiab lub zog txav mus los.Lub kaw lus tswj xyuas kev ua haujlwm thiab lwm yam haujlwm ntawm lub cev muaj zog, suav nrog kev tswj kev pib thiab nres ntawm lub elevator, thiab kev saib xyuas kev nyab xeeb.
Muaj ntau yam yuav tsum tau lubricated nyob rau hauv elevator khoom, xws li traction gearboxes, hlau ropes, guideways, hydraulic bumpers thiab sedan qhov rooj machines.
Rau ib tug toothed traction of elevator, txo lub iav lub thawv ntawm nws cov traction system muaj kev ua haujlwm ntawm kev txo cov zis ceev ntawm lub tshuab traction thiab ua kom cov zis torque.Traction iav reducer gearbox qauv muaj ntau yam uas nquag siv turbine worm hom, bevel iav hom thiab hom planetary iav.Cov turbine worm hom traction tshuab turbine feem ntau siv cov bronze hnav resistant, cov cab siv cov nplaim carburized thiab quenched alloy steel, cov cab iav iav hniav zawv zawg loj dua, cov hniav sib cuag lub sij hawm ntev, thiab kev sib txhuam thiab hnav yog qhov tseem ceeb.Yog li ntawd, tsis muaj teeb meem dab tsi ntawm turbine worm tsav, muaj qhov siab siab thiab tiv thaiv hnav.
Ib yam li ntawd, bevel iav thiab planetary iav tsheb laij teb kuj muaj qhov siab siab thiab tiv thaiv hnav teeb meem.Tsis tas li ntawd, cov roj siv rau cov tsheb laij teb yuav tsum muaj fluidity zoo ntawm qhov kub thiab txias thiab zoo oxidation stability thiab thermal stability ntawm qhov kub thiab txias.Yog li ntawd, lub reducer iav lub thawv nrog cov hniav traction tshuab feem ntau xaiv cov turbine cab iav roj nrog lub viscosity ntawm VG320 thiab VG460, thiab hom roj lubricating no kuj tseem siv tau los ua lub lubrication ntawm cov escalator saw.Kev ua tau zoo ntawm kev hnav thiab lubrication tau zoo heev.Nws tsim cov roj zaj duab xis muaj zog heev ntawm cov hlau nto thiab ua rau cov hlau nto ntev.Nws tuaj yeem txo qhov kev sib txhuam ntawm cov hlau, kom lub iav tuaj yeem tau txais lubrication zoo thiab kev tiv thaiv tam sim ntawd thaum pib.Gear lubricating roj muaj cov dej tsis zoo, oxidation kuj thiab muaj zog adhesion.Nws tuaj yeem txhim kho qhov nruj ntawm lub thawv iav (worm gearbox) thiab txo cov roj to.
Rau cov roj ntawm lub gearbox ntawm lub tshuab traction, qhov kub ntawm lub tshuab qhov chaw thiab cov kabmob ntawm lub elevator iav lub thawv yuav tsum tsawg dua 60 ° C, thiab cov roj kub hauv lub chassis yuav tsum tsis pub tshaj 85 ° C. Cov roj yuav tsum. siv raws li cov qauv sib txawv thiab kev ua haujlwm ntawm of the elevator, thiab cov roj, roj kub thiab roj to yuav tsum tau them sai sai rau.
