Nyob rau hauv ib lub cav niaj hnub muaj cov mounted units, uas yog tsav los ntawm ib tug siv.Rau ib txwm ua haujlwm ntawm tus tsav, ib chav tsev ntxiv tau qhia rau hauv nws - lub zog siv lub zog.Nyeem tag nrho txog chav tsev no, nws cov qauv tsim, hom thiab kev ua haujlwm, nrog rau kev xaiv thiab hloov pauv hauv kab lus.

 

Dab tsi yog qhov tsav siv tensioner?

Tsav txoj siv tensioner (cov menyuam nro lossis tsav txoj siv tensioner) - chav tsev ntawm lub tshuab tsav rau mounted units ntawm lub cav combustion;ib tug menyuam nrog lub caij nplooj ntoos hlav lossis lwm yam txheej txheem uas muab qhov tsim nyog ntawm qhov nro ntawm txoj siv tsav.

Qhov zoo ntawm kev tsav tsheb ntawm mounted units - lub tshuab hluav taws xob, lub twj tso kua mis dej, lub twj tso kua mis lub zog (yog tias muaj), lub tshuab cua txias compressor - feem ntau nyob ntawm kev ua haujlwm ntawm lub zog hluav taws xob thiab lub peev xwm ua haujlwm ntawm tag nrho lub tsheb.Ib qho kev tsim nyog rau kev ua haujlwm ib txwm muaj ntawm kev tsav tsheb ntawm cov mounted yog qhov tseeb nruj ntawm txoj siv sia siv hauv kev tsav tsheb - nrog lub zog tsis muaj zog, txoj siv tawv yuav plam raws cov rub, uas yuav ua rau muaj qhov hnyav ntxiv thiab txo qis hauv cov khoom siv. efficiency ntawm cov units;Kev nro ntau dhau kuj ua rau tus nqi hnav ntawm cov khoom tsav thiab ua rau cov khoom tsis txaus ntseeg.Nyob rau hauv niaj hnub motors, qhov yuav tsum tau degree ntawm nro ntawm tus tsav txoj siv yog muab los ntawm ib tug auxiliary chav tsev - ib tug nro cov menyuam los yog ib tug yooj yim tensioner.

Tus tsav txoj siv tensioner yog qhov tseem ceeb rau kev ua haujlwm ntawm lub zog ib txwm, yog li qhov no yuav tsum tau hloov pauv thaum muaj kev ua haujlwm tsis zoo.Tab sis ua ntej yuav ib tug tshiab roller, koj yuav tsum to taub nws cov uas twb muaj lawm hom, tsim thiab lub hauv paus ntsiab lus ntawm kev ua hauj lwm.

 

Hom thiab tsim ntawm tsav siv tensioners

Txhua txoj siv tawv tensioner muaj ob ntu: ib qho khoom siv tensioning uas tsim kom muaj lub zog tsim nyog, thiab cov menyuam uas xa cov quab yuam no mus rau txoj siv.Kuj tseem muaj cov khoom siv uas siv cov tensioner-damper - lawv muab tsis tau tsuas yog qhov tsim nyog txoj siv tawv nruj, tab sis kuj txo qhov kev siv ntawm txoj siv thiab pulleys ntawm cov units nyob rau hauv ib ntus hom ntawm kev khiav hauj lwm ntawm lub hwj chim unit.

Lub tensioner tuaj yeem muaj ib lossis ob lub rollers, cov khoom no yog tsim los ntawm cov hlau lossis yas log nrog lub ntsej muag ua haujlwm du uas siv txoj hlua khi.Cov menyuam yog mounted ntawm ib tug tensioning ntaus ntawv los yog nyob rau hauv ib tug tshwj xeeb bracket los ntawm ib tug dov bearing (pob los yog cov menyuam, feem ntau ib-kab, tab sis muaj cov khoom siv nrog ob-kab bearings).Raws li txoj cai, qhov chaw ua haujlwm ntawm cov menyuam yog du, tab sis muaj cov kev xaiv nrog cov dab tshos lossis tshwj xeeb protrusions uas tiv thaiv txoj siv tsis txhob ntog thaum lub cav khiav.

Cov chais yog ntsia ncaj qha rau ntawm cov khoom siv tensioning los yog ntawm qhov nruab nrab ntawm qhov sib txuas ntawm ntau yam qauv.Cov khoom siv tensioning tuaj yeem muab faib ua ob pawg raws li txoj kev kho qhov nro quab yuam ntawm txoj siv tsav:

● Nrog phau ntawv hloov kho qhov ntsuas ntawm qhov nro;
● Nrog kev hloov kho tsis siv neeg ntawm qhov ntsuas qhov nro.

Thawj pab pawg suav nrog cov txheej txheem yooj yim tshaj plaws hauv kev tsim, uas siv eccentric thiab swb tensioning li.Lub eccentric tensioner yog tsim nyob rau hauv daim ntawv ntawm ib tug roller nrog ib tug offset axis, thaum tig ib ncig ntawm lub rollers yog coj los ze zog los yog deb ntawm txoj siv, uas muab ib tug kev hloov nyob rau hauv nruj quab yuam.Lub slider tensioner yog tsim nyob rau hauv daim ntawv ntawm ib tug menyuam mounted rau ib tug movable slider uas yuav txav tau raws li qhov zawj ntawm phau ntawv qhia (bracket).Kev txav ntawm cov menyuam raws li cov lus qhia thiab nws qhov kev txhim kho hauv txoj haujlwm xaiv yog ua los ntawm cov ntsia hlau, cov lus qhia nws tus kheej raug ntsia rau ntawm txoj siv, yog li ntawd, thaum cov menyuam txav raws nws, lub zog quab yuam hloov.

Cov khoom siv nrog kev hloov kho ntawm txoj siv tawv nruj ntawm cov tshuab niaj hnub no tsis tshua siv, vim tias lawv muaj qhov tsis zoo - qhov yuav tsum tau hloov qhov cuam tshuam thaum thawj qhov kev teeb tsa ntawm qhov no thiab raws li txoj siv sia stretches.Xws li cov tensioners tsis tuaj yeem muab qhov tsim nyog ntawm txoj siv tawv nruj thaum lub sijhawm ua haujlwm tag nrho, thiab kev hloov kho phau ntawv tsis tas yuav txuag qhov xwm txheej - tag nrho qhov no ua rau hnyav hnyav ntawm cov khoom tsav.

Yog li ntawd, niaj hnub motors siv tensioning li nrog tsis siv neeg hloov.Cov tensioners zoo li no tau muab faib ua peb pawg raws li tus qauv tsim thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm:

● Raws li torsion springs;
● Raws li compression springs;
● Nrog dampers.

Cov cuab yeej siv dav tshaj plaws yog ua raws li cov torsion springs - lawv yog cov compact thiab ua tau zoo rau lawv txoj haujlwm.Lub hauv paus ntawm cov cuab yeej yog qhov loj-inch coiled caij nplooj ntoos hlav tso rau hauv lub khob cylindrical.Lub caij nplooj ntoos hlav nrog ib co coil yog tsau nyob rau hauv lub khob, thiab lub opposite coil rests ntawm lub bracket nrog ib tug roller, lub iav thiab lub bracket yuav tig tau ntawm ib tug tej lub kaum sab xis txwv los ntawm cov nres.Hauv kev tsim cov cuab yeej, lub iav thiab lub bracket yog tig ntawm ib lub kaum ntse ntse thiab tsau rau hauv txoj hauj lwm no los ntawm cov cuab yeej kev nyab xeeb (xyuas).Thaum mounting lub tensioner ntawm lub cav, lub check raug tshem tawm thiab lub bracket yog deflected nyob rau hauv qhov kev txiav txim ntawm lub caij nplooj ntoos hlav - yog li ntawd, cov menyuam rests tiv thaiv txoj siv, muab qhov tsim nyog degree ntawm nws cuam tshuam.Nyob rau hauv lub neej yav tom ntej, lub caij nplooj ntoos hlav yuav tuav lub teeb nro, ua kev hloov tsis tsim nyog.

Cov khoom siv raws li compression springs yog siv tsawg dua, vim tias lawv siv ntau qhov chaw thiab tsis muaj txiaj ntsig.Lub hauv paus ntawm lub tensioning ntaus ntawv yog ib tug bracket nrog ib tug roller, uas muaj ib tug swivel kev twb kev txuas nrog ib tug twisted cylindrical caij nplooj ntoos hlav.Qhov thib ob kawg ntawm lub caij nplooj ntoos hlav yog mounted rau ntawm lub cav - qhov no ua kom ntseeg tau qhov tsim nyog siv kev cuam tshuam.Raws li nyob rau hauv cov ntaub ntawv dhau los, qhov nro quab yuam ntawm lub caij nplooj ntoos hlav yog teem rau ntawm lub Hoobkas, yog li tom qab kev txhim kho cov cuab yeej ntawm lub cav, ib daim tshev los yog fuse ntawm ib tug txawv tsim raug tshem tawm.

Kev loj hlob ntawm tensioners nrog lub caij nplooj ntoos hlav compression yog ib qho khoom siv nrog dampers.Lub tensioner muaj cov qauv tsim zoo ib yam li tau piav qhia saum toj no, tab sis lub caij nplooj ntoos hlav hloov los ntawm lub damper, uas yog mounted rau bracket nrog cov menyuam thiab lub cev muaj zog nrog kev pab los ntawm eyelets.Lub damper muaj lub compact hydraulic shock absorber thiab lub caij nplooj ntoos hlav coiled, thiab lub shock absorber tuaj yeem nyob rau hauv ob qho tib si hauv lub caij nplooj ntoos hlav thiab ua raws li kev txhawb nqa rau lub caij nplooj ntoos hlav kawg.Lub damper ntawm tus qauv tsim no muab cov kev cuam tshuam ntawm txoj hlua uas tsim nyog, thaum smoothing tawm qhov kev vibration ntawm txoj siv tawv thaum pib lub cav thiab nyob rau hauv lub sijhawm hloov pauv.Lub xub ntiag ntawm lub damper rov txuas ntxiv lub neej ntawm lub tsav ntawm cov mounted units thiab xyuas kom meej nws cov hauj lwm zoo dua.

Hauv kev xaus, nws yuav tsum tau muab sau tseg tias tus qauv piav qhia muaj tensioners nrog ob qho tib si ib thiab ob lub rollers.Nyob rau hauv rooj plaub no, cov khoom siv nrog ob lub rollers tuaj yeem muaj ib qho khoom siv tensioning, los yog cais cov khoom siv rau txhua tus rollers.Muaj lwm yam kev daws teeb meem, tab sis lawv tau txais kev faib me me, yog li peb yuav tsis xav txog lawv ntawm no.

 

Cov teeb meem ntawm kev xaiv, hloov thiab hloov kho ntawm tus tsav siv tensioner

Lub nro cov menyuam ntawm txoj siv tsav, zoo li txoj siv sia nws tus kheej, muaj cov peev txheej tsawg, kev txhim kho uas yuav tsum tau hloov.Ntau hom tensioners muaj cov peev txheej sib txawv - qee qhov ntawm lawv (qhov yooj yim eccentric) yuav tsum tau hloov tsis tu ncua thiab ua ke nrog kev hloov ntawm txoj siv, thiab cov khoom siv raws li cov springs thiab nrog cov dampers tuaj yeem ua haujlwm yuav luag txhua lub sijhawm ua haujlwm ntawm lub zog.Lub sijhawm thiab txheej txheem rau kev hloov cov khoom siv tensioning yog qhia los ntawm cov chaw tsim khoom ntawm ib lub zog tshwj xeeb - cov lus pom zoo no yuav tsum tau ua nruj me ntsis, txwv tsis pub muaj ntau yam tsis zoo rau lub zog hluav taws xob, suav nrog nws cov jamming (vim overheating vim nres lub twj tso kua mis. ).

Tsuas yog cov hom thiab cov qauv ntawm cov tensioners uas tau pom zoo los ntawm cov chaw tsim khoom ntawm lub zog hluav taws xob yuav tsum raug coj los hloov, tshwj xeeb tshaj yog rau cov tsheb nyob rau hauv warranty.Cov khoom siv "tsis yog haiv neeg" yuav tsis sib haum nrog cov yam ntxwv ntawm "native", yog li lawv cov kev teeb tsa ua rau muaj kev hloov pauv ntawm qhov nro quab yuam ntawm txoj siv sia thiab kev ua haujlwm tsis zoo ntawm kev ua haujlwm ntawm cov tsav ntawm cov mounted units.Yog li ntawd, xws li ib tug hloov yuav tsum tau resorted rau tsuas yog nyob rau hauv heev mob.

Thaum muas cov khoom siv tensioning, koj yuav tsum yuav tag nrho cov khoom tsim nyog rau nws (yog tias lawv tsis suav nrog) - fasteners, brackets, springs, thiab lwm yam. Qee zaum, koj tuaj yeem nqa tsis tau tag nrho cov tensioners, tab sis kho cov khoom siv - tsuas yog chais nrog ntsia. bearings, brackets, dampers assembled nrog springs, thiab lwm yam.

Kev hloov ntawm txoj siv tawv tensioner yuav tsum tau ua raws li cov lus qhia rau kev kho thiab tu lub tsheb.Qhov kev ua haujlwm no tuaj yeem ua tau ob qho tib si nrog txoj siv hlua khi thiab nrog txoj siv tawv tshem tawm - nws tag nrho yog nyob ntawm tus tsim ntawm tus tsav thiab qhov chaw ntawm lub tensioning ntaus ntawv.Txawm li cas los xij, kev teeb tsa lub caij nplooj ntoos hlav tensioners yeej ib txwm ua raws li tib txoj kev: cov cuab yeej thiab txoj siv tawv yog thawj zaug ntsia rau hauv lawv qhov chaw, thiab tom qab ntawd cov tshev raug tshem tawm - qhov no ua rau kev tso tawm ntawm lub caij nplooj ntoos hlav thiab qhov nro ntawm qhov chaw. siv.Yog hais tias yog vim li cas lub installation ntawm xws li ib tug tensioner yog ua tsis raug, ces nws yuav nyuaj rau re-install nws.

Yog hais tias lub tensioning ntaus ntawv raug xaiv thiab ntsia rau ntawm lub cav, lub tsav ntawm cov units yuav ua hauj lwm ib txwm, kom ntseeg tau tias lub lag luam ntawm tag nrho cov hwj chim unit.
