Lub tshuab tsav saw yog dab tsi? Lub tshuab tsav saw yog ib txoj kev sib kis uas xa cov kev txav mus los thiab lub zog ntawm lub sprocket tsav uas muaj cov hniav tshwj xeeb mus rau lub sprocket tsav uas muaj cov hniav tshwj xeeb los ntawm cov saw.
Lub saw hlau tsav muaj lub peev xwm thauj khoom muaj zog (qhov nruj siab tso cai) thiab tsim nyog rau kev sib kis ntawm cov ncej sib luag ntawm qhov deb ntev (ob peb meters). Nws tuaj yeem ua haujlwm hauv qhov chaw nyuaj xws li kub siab lossis roj av. Nws muaj qhov tseeb tsim khoom thiab teeb tsa tsawg thiab tus nqi qis. Txawm li cas los xij, qhov ceev tam sim ntawd thiab qhov sib piv kis ntawm lub saw hlau tsav tsis ruaj khov, yog li qhov kis tsis ruaj khov thiab muaj qee qhov cuam tshuam thiab suab nrov. Nws feem ntau siv rau hauv kev tsuas, kev ua liaj ua teb, roj av, maus taus / tsheb kauj vab thiab lwm yam lag luam thiab tshuab, thiab ntau yam khoom siv kho vajtse, khoom siv hauv tsev, thiab kev lag luam hluav taws xob. Cov kab ntau lawm kuj siv ob chav ceev saw hlau los thauj cov cuab yeej.
Cov saw hlau uas hu ua ob chav ceev yog cov saw hlau dov. Qhov ceev txav V0 ntawm cov saw hlau tseem tsis hloov pauv. Feem ntau, qhov ceev ntawm cov dov = (2-3) V0.
Cov khoom siv automation ib txwm tsis tshua siv cov saw hlau tsav, vim tias qhov yuav tsum tau muaj peev xwm thauj khoom hauv qab cov xwm txheej ua haujlwm dav dav tsis siab, thiab qhov tseem ceeb dua yog muab tso rau ntawm kev kub ceev, kev raug siab, kev saib xyuas tsawg, suab nrov tsawg, thiab lwm yam. Cov no yog qhov tsis muaj zog ntawm cov saw hlau tsav. Feem ntau, lub zog ntawm kev tsim qauv mechanism thaum ntxov tsav cov khoom siv ntawm ntau lub mechanisms los ntawm kev sib kis saw hlau. Cov qauv mechanism khoom siv "ib axis, ntau qhov kev txav mus los" no zoo li muaj cov ntsiab lus kev txawj ntse, tab sis nws tsis nrov tam sim no (kev ywj pheej tsis zoo, kev hloov kho tsis yooj yim, kev tsim qauv siab), vim tias ntau daim ntawv thov hauv lub tuam txhab feem ntau yog cov khoom siv pneumatic, thiab ntau yam mechanisms Txhua tus muaj lub zog ywj pheej (lub tog raj kheej), thiab cov kev txav mus los tuaj yeem tswj tau yooj yim los ntawm kev programming.
Cov khoom sib xyaw ntawm cov saw hlau tsav yog dab tsi?
Kev tsav tsheb saw yog ib txoj kev sib kis uas cov saw xa lub zog los ntawm kev sib txuas ntawm cov menyuam thiab cov hniav ntawm lub sprocket. Cov khoom koom nrog hauv kev tsav tsheb saw suav nrog cov sprockets, saw, idlers thiab cov khoom siv cuam tshuam (xws li kev kho qhov nruj, cov lus qhia saw), uas tuaj yeem sib phim thiab siv tau raws li qhov xwm txheej tiag tiag. Ntawm lawv, cov saw yog tsim los ntawm cov menyuam, cov phaj sab hauv thiab sab nraud, bushings, pins thiab lwm yam.
Cov yam ntxwv tseem ceeb ntawm txoj kev tsav tsheb tsis tuaj yeem tsis quav ntsej.
1. Qhov Siab. Qhov deb ntawm nruab nrab ntawm ob lub log sib txuas ntawm cov saw hlau. Qhov siab dua, qhov loj dua ntawm cov khoom, uas tuaj yeem xa hluav taws xob ntau dua thiab dais tau cov khoom hnyav dua (rau kev sib kis ceev qis thiab hnyav, qhov siab yuav tsum xaiv qhov loj). Feem ntau, koj yuav tsum xaiv cov saw hlau uas muaj qhov siab tsawg kawg nkaus uas muaj peev xwm xa hluav taws xob xav tau (yog tias cov saw hlau ib kab tsis muaj peev xwm txaus, koj tuaj yeem xaiv cov saw hlau ntau kab) kom tau txais suab nrov qis thiab ruaj khov.
2. Qhov piv ntawm kev sib kis tam sim ntawd. Qhov piv ntawm kev sib kis tam sim ntawd ntawm lub saw hlau tsav yog i = w1 / w2, qhov twg w1 thiab w2 yog qhov ceev ntawm kev sib hloov ntawm lub sprocket tsav thiab lub sprocket tsav feem. i yuav tsum ua tau raws li qee yam mob (tus naj npawb ntawm cov hniav ntawm ob lub sprocket yog sib npaug, thiab qhov ntev ntawm sab nruj yog qhov lej ntawm lub sijhawm suab), yog qhov tsis hloov pauv.
3. Tus naj npawb ntawm cov hniav pinion. Kev nce tus naj npawb ntawm cov hniav pinion kom tsim nyog tuaj yeem txo qhov kev txav tsis sib xws thiab cov khoom thauj dynamic.
