Traction Sheave
traction log yog hlua hlua ntawm lub tshuab traction, tseem hu ua traction hlua log lossis tsav hlua log. Nws yog ib qho khoom siv rau kev xa cov hluav taws xob traction hauv elevator, uas siv cov kev sib txhuam ntawm cov hlua hlau traction thiab cov hlua hlua ntawm lub traction log rim kom xa hluav taws xob, thiab tau nruab rau ntawm cov cab iav ncej hauv lub reducer. Yog hais tias nws yog ib tug gearless traction tshuab, nws yuav tsum tau ntsia rau ntawm ib sab ntawm lub nres, nyob rau tib axis li lub cev muaj zog ncej thiab nres ncej.
(1) Cov khoom siv thiab cov qauv tsim rau cov log tsheb traction
① Cov khoom thiab cov txheej txheem yuav tsum tau: Vim lub fact tias lub traction log yuav tsum tau dais tag nrho cov dynamic thiab zoo li qub loads ntawm lub tsheb, load peev xwm, counterweight thiab lwm yam khoom siv, nws yuav tsum tau hais tias lub traction log muaj siab zog, zoo toughness, hnav tsis kam, thiab cuam tshuam tsis kam. Yog li ntawd, QT60-2 ductile hlau feem ntau yog siv rau hauv cov khoom. Txhawm rau txo qhov hnav ntawm traction steel hlau hlua nyob rau hauv lub traction log zawj, ntxiv rau xaiv ib tug haum zawj hom, yuav tsum muaj qhov tsim nyog yuav tsum tau rau lub roughness thiab hardness ntawm qhov chaw ua hauj lwm ntawm lub zawj.
② Txoj kab uas hla ntawm lub log traction: Txoj kab uas hla ntawm lub log traction yuav tsum siab dua 40 npaug ntawm txoj kab uas hla ntawm txoj hlua hlau. Hauv kev xyaum, nws yog feem ntau coj li 45-55 zaug, qee zaum txawm ntau dua 60 zaug. Vim hais tias txhawm rau txo qhov nce ntawm qhov ntim ntawm lub tshuab traction, qhov txo qis ntawm cov reducer nce, yog li nws txoj kab uas hla yuav tsum tsim nyog.
③ Kev tsim kho ntawm lub log traction: tag nrho lub log traction tau muab faib ua ob ntu, nrog lub nruas nyob nruab nrab thiab lub log rim hom hlua groove txiav ntawm lub log. Lub log sab nraud yog haum nrog lub nruas sab hauv thiab txuas nrog pob khawm bolts los tsim ib lub log traction tag nrho. Cov ncej ntawm nws lub log traction yog cov cab iav ncej hauv lub reducer.
(2) Cov duab ntawm traction log hlua zawj
Lub zog traction ntawm lub qub cheeb tsam txav of elevator yog tsim los ntawm kev sib txhuam quab yuam ntawm txoj hlua traction thiab traction log hlua zawj.
