Feem ntau ntawm lub log tsav tsheb thiab txhua lub log tsav tsheb muaj cov gearboxes uas tig thiab hloov lub zog.Lub hauv paus ntawm xws li gearboxes yog bevel khub - nyeem tag nrho cov mechanisms, lawv hom, tsim thiab kev khiav hauj lwm, raws li zoo raws li lawv cov kev xaiv thiab hloov, nyob rau hauv tsab xov xwm.
Dab tsi yog conical khub?
Ib khub bevel yog ib hom iav kis tau tus mob ntawm lub tsheb thiab lwm yam khoom siv, tsim los ntawm ob lub bevel iav, lub axes ntawm lub kaum sab xis (feem ntau ncaj) rau ib leeg.
Hauv kev sib kis ntawm tsheb, tsheb laij teb thiab tshuab, nrog rau ntau yam khoom siv, feem ntau yuav tsum tau hloov cov kev taw qhia ntawm torque ntws.Piv txwv li, nyob rau hauv lub rear-log tsav tsheb, lub torque kis tau los ntawm lub kiv cua ncej yog perpendicular mus rau lub qag axis, thiab qhov no ntws yuav tsum tau tig 90 degrees los tsav lub log.Nyob rau hauv MTZ log tsheb laij teb nrog rau pem hauv ntej tsav qag, cov kev taw qhia ntawm lub torque flow yuav tsum tig 90 degrees peb zaug, txij li thaum lub axles ntawm lub log nyob rau hauv qab ntawm lub axis ntawm lub post beam.Thiab nyob rau hauv ntau chav nyob, tshuab thiab khoom siv, lub zog torque yuav tsum tau tig ntawm qhov sib txawv ntau zaus.Nyob rau hauv tag nrho cov no, ib tug tshwj xeeb iav tsheb ciav hlau raws li ob bevel gears yog siv - ib tug bevel khub.
Conical khub muaj ob lub luag haujlwm tseem ceeb:
- Kev sib hloov ntawm lub torque ntws ntawm ib lub kaum ntse ntse (feem ntau 90 degrees);
- Hloov tus nqi ntawm torque.
Thawj qhov teeb meem yog daws los ntawm tus tsim ntawm lub zog ntawm lub bevel khub, lub axes ntawm uas yog nyob rau ntawm ib tug kaum sab xis.Thiab qhov teeb meem thib ob yog daws los ntawm kev siv lub zog nrog ntau tus hniav sib txawv, vim tias lub tsheb ciav hlau iav nrog ib qho piv txwv tshwj xeeb yog tsim.
Bevel khub ua lub luag haujlwm tseem ceeb hauv kev ua haujlwm ntawm ntau lub tshuab kis tau tus mob thiab lwm lub tshuab, yog tias ib qho los yog ob lub iav hnav tawm los yog tawg, tag nrho cov khub yuav tsum tau hloov.Tab sis ua ntej yuav ib tug tshiab conical khub, koj yuav tsum to taub tus tsim ntawm no mechanism, nws cov uas twb muaj lawm hom, yam ntxwv thiab nta ntawm kev ua hauj lwm.
Hom thiab tsim ntawm conical khub
Txhua tus khub bevel muaj ob lub zog uas muaj lub ntsej muag zoo li ntawm qhov chaw pib, thiab kev sib tshuam ncej axes.Ntawd yog, lub zog ntawm cov khub muaj lub ntsej muag bevel, thiab lawv nyob ntawm txoj cai lossis sib txawv ntawm ib leeg.
Bevel khub sib txawv nyob rau hauv cov duab ntawm cov hniav thiab kev npaj ntawm lub zog sib piv rau ib leeg.
Nws yuav tsum tau muab sau tseg tias lub zog ntawm lub bevel khub, nyob ntawm seb lub hom phiaj, muaj lawv tus kheej lub npe:
● Cov tsav tsheb tsuas yog cogwheel xwb;
● Tus qhev yog lub iav.
Raws li cov duab ntawm cov hniav, conical khub yog:
● Nrog cov hniav ncaj;
● Nrog cov hniav nkhaus;
● Nrog cov hniav ncig;
● Nrog tangential (oblique) cov hniav.
Gears nrog cov hniav ncaj yog qhov yooj yim tshaj plaws hauv kev tsim - lawv raug txiav mus rau lub axis ntawm lub log.Circular hniav yog complex, lawv raug txiav nyob ib ncig ntawm ib ncig ntawm ib tug tej txoj kab uas hla.Tangential (los yog oblique) cov hniav zoo ib yam li cov hniav ncaj, txawm li cas los xij, lawv tau deflected los ntawm cov iav axis.Qhov nyuaj tshaj plaws yog cov hniav curvilinear, qhov tsis txaus ntseeg uas tau teeb tsa los ntawm ntau yam qauv (kev ua haujlwm).Xws li ntau yam nyob rau hauv cov duab ntawm cov hniav ntawm bevel iav yog piav qhia los ntawm qhov sib txawv ntawm lub peev xwm ntawm lub zog thiab lawv lub suab nrov.Gears nrog cov hniav ncaj tiv taus qhov tsawg tshaj plaws, lawv kuj yog qhov nrov tshaj plaws.Oblique hniav iav tsis muaj suab nrov thiab khiav zoo dua.Thiab cov khoom loj tshaj plaws tuaj yeem tiv taus cov iav nrog cov hniav nkhaus thiab ncig, lawv kuj yog qhov nrov tshaj plaws.
Raws li qhov txheeb ze ntawm lub zog, cov khub tau muab faib ua ob pawg loj:
● Ordinary, nrog rau coincident vertices ntawm thawj qhov chaw ntawm lub zog (uas yog, yog hais tias koj xav txog tej yam lub zog nyob rau hauv daim ntawv ntawm cones, ces lawv vertices yuav converge ntawm ib tug taw tes);
● Hypoid, nrog kev hloov chaw ntsug ntawm qhov chaw pib ntawm lub zog.
Conicalkhub nrog cov hniav ncigHypoid conical khub nrog nkhaus hniav
Nyob rau hauv thawj rooj plaub, lub axes ntawm lub zog yog nyob rau hauv ib lub dav hlau, nyob rau hauv lub thib ob - nyob rau hauv ib tug ntawm cov dav hlau, lub axes yog offset.Hypoid gears tsuas yog tsim los ntawm bevel iav nrog oblique lossis nkhaus hniav, lawv muaj peev xwm thauj khoom siab thiab ua haujlwm yuav luag ntsiag to.
Bevel iav tuaj yeem ua rau tib lub sijhawm nrog cov ncej lossis cais los ntawm nws.Feem ntau, cov ncej muaj me me-inch iav, lub zog loj ntawm cov tsav qag gearboxes muaj qhov loj sab hauv rau mounting ntawm cov vaj tsev sib txawv.Cov iav yog ua los ntawm cov qib tshwj xeeb ntawm cov hlau siv ntau yam thev naus laus zis - tig thiab milling, knurling, stamping ua raws li knurling, thiab lwm yam. Conical khub yuav tsum tau lubrication tas li rau lawv txoj haujlwm, thiab cov hom roj tshwj xeeb yog siv hauv cov iav hypoid.
Performance thiab standardization ntawm bevel iav
Ntawm cov yam ntxwv tseem ceeb ntawm bevel iav yuav tsum tau hais txog:
● Iav piv - xam los ntawm qhov piv ntawm tus naj npawb ntawm cov hniav ntawm lub iav thiab lub log (feem ntau yog nyob rau hauv qhov ntau ntawm 1.0 mus rau 6.3, txawm tias nws yuav txawv ntawm txoj kev loj);
● Qhov nruab nrab ib txwm thiab sab nraud cov khoom siv ncig;
● Geometric qhov ntev ntawm cov iav.
Kuj tseem muaj lwm qhov tsis zoo ntawm cov iav bevel, tab sis thaum lub sijhawm ua haujlwm lossis kho lub iav los yog lwm yam kev siv, lawv tsis siv.
Nws yuav tsum tau muab sau tseg tias nyob rau hauv Russia tus yam ntxwv thiab tsim nta ntawm bevel gears yog standardized, lub zog thiab cov mechanisms lawv tus kheej yog tsim nyob rau hauv raws li GOST 19325-73 (feem ntau rau tag nrho cov zog raws li bevel zog), 19624-74 (spur zog. ), 19326-73 (lub zog nrog cov hniav ncig), GOST 1758-81 thiab lwm yam.
Kev siv cov conical khub hauv tsheb
Bevel iav feem ntau yog siv nyob rau hauv gearboxes ntawm kis ntawm lub tsheb rau ntau lub hom phiaj:
Lub bevel khub yog ib qho ntawm lub hauv paus ntawm tsav qag gearbox
● Raws li cov iav tseem ceeb hauv lub gearboxes ntawm lub axles ntawm lub log tsav tsheb thiab txhua lub log tsav tsheb.Feem ntau, xws li ib tug kis tau tus mob yog ua nyob rau hauv daim ntawv ntawm ib tug khub ntawm lub zog sib txawv, ib tug ntawm cov ( qhev) yog mounted ncaj qha rau ntawm qhov sib txawv vaj tse.Lub iav ib leeg yog tsim ua ke nrog cov ncej, ob lub iav yog ua los ntawm cov ncej thiab lwm lub iav (bevel lossis cylindrical);
● Raws li lub sab sauv thiab qis gearboxes ntawm kev tsav tsheb pem hauv ntej ntawm lub log tsheb laij teb.Nyob rau hauv lub Upper gearboxes, ob lub zog muaj peev xwm muaj tib tus naj npawb ntawm cov hniav thiab qhov ntev, lawv tau ua tib lub sijhawm nrog lawv cov ncej.Nyob rau hauv qis gearboxes, lub iav tsav yog ua los ntawm txoj kab uas hla loj thiab muaj qhov tshwj xeeb tsim rau kev sib txuas nrog lub log;
● Hauv ntau chav sib kis thiab lwm lub tshuab.Cov khub conical tej zaum yuav muaj cov qauv sib txawv, tab sis feem ntau lawv sib haum rau cov lus hais saum toj no.
Yog li, lub tsheb muaj peev xwm muaj los ntawm ib qho (ntawm ib lub tsheb nrog ib lub qag tsav) mus rau peb (hauv tag nrho lub log tsav peb-qag) lossis ntau dua (hauv ntau lub tsheb nrog txhua lub log tsav) bevel khub, thiab hauv tsheb laij teb nrog rau pem hauv ntej tsav qag muaj plaub bevel khub, tsawg kawg yog ib tug ntxiv xws li mechanism yuav siv tau nyob rau hauv lub kis tau tus mob ntawm lub tsheb laij teb tig lub torque mus rau lub hwj chim tshem tawm ncej.
Yuav ua li cas xaiv thiab hloov ib tug conical khub kom raug
Thaum lub sij hawm ua hauj lwm ntawm lub tsheb, lub conical khub yog raug rau ib tug tseem ceeb loads - nws yog los ntawm nws hais tias tag nrho cov torque los ntawm lub cav yog nkag mus rau lub tsav qag, thiab nws kuj yuav raug kev vibrations, shocks thiab shocks vim muaj kev cuam tshuam nrog lwm yam. ntu.Raws li qhov tshwm sim, dhau sijhawm, cov hniav ntawm cov iav hnav tawm ntawm cov ntsiab lus ntawm kev sib cuag, chips thiab hardening tuaj yeem tshwm sim hauv lawv, thiab qee zaum cov hniav tau tawg tag.Tag nrho cov no yog manifested los ntawm deterioration ntawm lub mechanism thiab muaj suab nrov.Yog tias xav tias muaj kev ua haujlwm tsis zoo, lub tshuab yuav tsum tau muab tshem tawm thiab kuaj xyuas, thaum lub iav tawg, lub bevel khub yuav tsum tau hloov.Nws tsis ua rau kev hloov pauv tsuas yog ib qho ntawm lub zog, txij li qhov no lub tshuab yuav sai sai dhau los ua qhov teeb meem dua.
Ib tug conical khub yuav tsum tau muab coj los hloov, uas nyob rau hauv tsim, loj thiab cov yam ntxwv sib haum mus rau lub yav tas los ntsia mechanism.Yog tias tsim nyog, koj tuaj yeem xaiv lub tshuab nrog lub iav sib txawv, uas yuav txhim kho kev ua haujlwm ntawm lub tsheb.Txawm li cas los xij, xws li kev hloov pauv yuav tsum tau ua nrog ceev faj thiab tsuas yog muaj kev ntseeg siab tias nws muaj peev xwm thiab ncaj ncees - qhov no tuaj yeem tshaj tawm los ntawm cov chaw tsim khoom nws tus kheej lossis cov kws tshaj lij.
Kev hloov cov iav bevel yuav tsum tau ua raws li cov lus qhia rau kev kho lub tsheb lossis tsheb laij teb.Feem ntau, txoj haujlwm no yuav tsum muaj kev cuam tshuam tseem ceeb hauv lub tsav qag thiab lub gearbox - los hloov lub zog, nws yog ib qho tsim nyog yuav luag tag nrho cov qag thiab nws cov txheej txheem.Qee zaum, bearings thiab sealing ntsiab yuav tsum tau hloov - lawv yuav tsum tau yuav ua ntej.Thaum txhim kho lub zog thiab sib sau ua ke lub gearbox, nws yog ib qho tsim nyog yuav tsum siv cov chaw tsim khoom pom zoo lubricants.Thiab tom qab kev kho tiav lawm, lub sijhawm luv luv ntawm lub gearbox yog tsim nyog.
Nrog rau kev xaiv kom raug thiab hloov cov khub conical, kho qhov sib kis tau zoo yuav ua haujlwm tau zoo, ua nws txoj haujlwm hauv txhua hom.
