Ratchet Pawl PM Sintered Part
Nyob rau hauv lub ratchet mechanism, lub luag hauj lwm ntawm Ratchet pawl PM sintered ib feem nres pawl yog los tiv thaiv lub ratchet los ntawm reversing.Ratchet pawl PM sintered ib feem ratchet mechanism, ib tug ib-txoj kev intermittent motion mechanism muaj li ntawm ratchet thiab pawl. Cov hniav ntawm ratchet feem ntau yog siv cov hniav ib-txoj kev, thiab lub pawl yog hinged ntawm lub rocker. Thaum lub rocker swings counterclockwise, tus tsav pawl yog muab tso rau hauv lub ratchet hniav kom thawb lub ratchet tig nyob rau hauv tib txoj kev.

Muaj nuj nqi
Hauv ratchet mechanism, kev ua haujlwm ntawm Ratchet pawl PM sintered ib feem nres pawl yog los tiv thaiv lub ratchet los ntawm kev thim rov qab.
Ratchet pawl PM sintered ib feem ratchet mechanism, ib-txoj kev sib quas ntus motion mechanism muaj li ntawm ratchet thiab pawl. Cov hniav ntawm ratchet feem ntau yog siv cov hniav ib-txoj kev, thiab lub pawl yog hinged ntawm lub rocker. Thaum lub rocker swings counterclockwise, tus tsav pawl yog muab tso rau hauv lub ratchet hniav kom thawb lub ratchet tig nyob rau hauv tib txoj kev.
Thaum lub pob zeb viav vias viav vias, lub ratchet swb hla lub ratchet log, thiab lub log ratchet nres. Thaum lub ratchet ua haujlwm, nws raug thawb ntawm lub pawl. Ib txhij, ratchet kuj tuaj yeem raug rau cov tshuaj tiv thaiv quab yuam ntawm ratchet.
Cov ntaub ntawv txuas ntxiv:
1. Lub hauv paus ntsiab lus ua haujlwm
Thaum lub rocker ntawm lub active feem swings counterclockwise, tus tsav pawl yog muab tso rau hauv cov hniav zawj ntawm lub ratchet, thiab lub ratchet yog thawb kom tig los ntawm lub kaum sab xis. Lub sijhawm no, qhov nres pawl swb ntawm tus hniav rov qab ntawm lub ratchet.
Thaum lub pob zeb pob zeb ntawm qhov chaw ua haujlwm viav vias clockwise, nres pawl tiv thaiv lub ratchet los ntawm kev tig clockwise, tab sis tus tsav pawl tuaj yeem xaub hla tus hniav rov qab ntawm lub ratchet, yog li lub ratchet tseem nyob twj ywm.
Zoo li qhov no, thaum rocking bar yog ua tiav reciprocating viav vias, ratchet tsuas yog ua rau ib txoj kev sib cuam tshuam. Nyob rau hauv tas li ntawd, lub reciprocating viav vias ntawm lub active feem yuav tau txais los ntawm lub cam mechanism ntawm lub viav vias follower, lub crank rocker mechanism, los yog los ntawm hydraulic kis tau tus mob thiab electromagnetic li.
2. Hom loj
1. Toothed ratchet (mechanism)
Ib leeg-ua yeeb yam ratchet mechanism, ob-ua yeeb yam ratchet mechanism, thim rov qab ratchet mechanism. Muaj cov hniav khov kho ntawm ntug sab nrauv lossis sab hauv; lub ratchet rotation lub kaum ntse ntse tsuas tuaj yeem yog ntau yam ntawm lub hauv paus lub kaum sab xis ntawm ob cov hniav uas nyob ib sab, thiab tuaj yeem hloov kho hauv cov theem. Cov qauv yog yooj yim, qhov chaw tsim khoom yog yooj yim, thiab lub zog yog txhim khu kev qha, tab sis nws yog ib qho yooj yim los ua suab nrov thiab cov hniav ntaj, thiab kev sib kis tsis zoo. Nws yog feem ntau siv nyob rau hauv lub transverse feed device ntawm lub worktable nyob rau hauv lub planer.
2. Kev sib txhuam ratchet (mechanism)
Lub zog yog kis los ntawm kev sib txhuam quab yuam ntawm lub pawl thiab lub ratchet log kom paub txog cov kauj ruam tsis sib xws ntawm lub ratchet log. Nws kuj yog feem ntau siv los ua tus nres lossis nres ntawm kev pub mis ntawm cov cuab yeej siv tshuab thiab cov tshuab tsis siv neeg.
3. Transcendent ratchet (mechanism)
Ntxiv rau qhov uas feem ntau siv los ua kom muaj kev sib cuam tshuam, nws tseem tuaj yeem ua tiav cov lus tsa suab, uas yog, qhov uas tau tsav tuaj yeem tig dhau ntawm qhov nquag. Siv nyob rau hauv lub rear qag ntawm lub tsheb kauj vab.
Nta thiab hom ratchet pawls
Toothed ratchet mechanism
Muaj ntau ntau hom ratchet mechanisms:
Los ntawm cov qauv
Lub ratchet mechanism tuaj yeem muab faib ua tus hniav ratchet mechanism thiab kev sib txhuam ratchet mechanism raws li daim ntawv qauv.
Lub toothed ratchet mechanism muaj cov qauv yooj yim thiab yooj yim rau kev tsim khoom; lub sijhawm piv ntawm kev txav thiab nres tuaj yeem pom tau los ntawm kev xaiv lub tshuab tsav tsheb tsim nyog. Qhov tsis zoo ntawm cov txheej txheem no yog tias cov hlab ntsha tuaj yeem hloov kho hauv cov kauj ruam nkaus xwb; lub suab nrov, cuam tshuam thiab hnav yog qhov loj, yog li nws tsis haum rau kev kub ceev.
Kev sib txhuam ratchet mechanism
Kev sib txhuam ratchet mechanism siv eccentric sector wedges los hloov lub ratchet nyob rau hauv lub toothed ratchet mechanism, thiab hloov lub ratchet log nrog toothless kev sib txhuam. Nws yog tus cwj pwm los ntawm kev sib kis ruaj khov thiab tsis muaj suab nrov; tus mob stroke tuaj yeem hloov kho steplessly. Txawm li cas los xij, vim kev sib kis los ntawm kev sib txhuam, yuav muaj kev swb. Txawm hais tias nws tuaj yeem ua lub luag haujlwm hauv kev tiv thaiv kev nyab xeeb, qhov tseeb ntawm kev sib kis tsis yog siab. Haum rau qhov ceev ceev thiab lub teeb load zaus.
Los ntawm kev koom tes
Lub ratchet mechanism tuaj yeem muab faib ua lwm yam meshing ratchet mechanism thiab ib qho meshing ratchet mechanism raws li txoj kev meshing.
Lub pawls los yog wedges ntawm sab nraud ratchet mechanism yog ntsia sab nraum lub ratchet, thaum lub pawls los yog wedges ntawm lub internal ratchet mechanism nyob rau hauv lub ratchet.
Internal ratchet mechanism
Vim qhov yooj yim ntawm kev ua, kev teeb tsa thiab kev saib xyuas, sab nraud meshing ratchet mechanism yog dav siv. Internal meshing ratchet mechanism yog tus yam ntxwv ntawm cov qauv compact thiab me me sab nraud qhov ntev.
Raws li daim ntawv txav ntawm tus neeg taug qab
Raws li daim ntawv txav ntawm tus neeg taug qab, lub ratchet mechanism tuaj yeem muab faib ua ib qho kev ua yeeb yam ratchet mechanism, ob lub yeeb yam ratchet mechanism thiab bidirectional ratchet mechanism.
Ib qho kev ua yeeb yam ratchet mechanism tsuas tuaj yeem thawb lub ratchet kom tig thaum lub active feem swings nyob rau hauv ib qho kev taw qhia.
Lub ob-txoj kev ratchet mechanism tsav ob pawls raws li thaum lub sij hawm reciprocating viav vias ntawm lub active rocker nyob rau hauv ob txoj kev, thiab thawb lub ratchet log ob zaug.
Qhov ob-acting ratchet mechanism feem ntau yog siv nyob rau hauv lub sij hawm uas lub load yog loj, qhov luaj li cas ntawm lub ratchet yog txwv, tus naj npawb ntawm cov hniav yog me me, thiab lub viav vias lub kaum sab xis ntawm lub active viav vias yog me dua cov hniav pitch ntawm lub ratchet.
Lub ratchet mechanism tau piav qhia saum toj no tsuas tuaj yeem ua ib txoj kev sib cuam tshuam hauv ib qho kev taw qhia. Ob txoj kev ratchet mechanism tuaj yeem paub qhov kev sib hloov ntawm lub ratchet nyob rau hauv ob txoj kev los ntawm kev hloov lub viav vias kev taw qhia ntawm lub ratchet. Daim duab qhia ob hom ntawm ob txoj kev ratchet mechanism, thiab ob txoj kev ratchet mechanism yuav tsum tau txais ib tug symmetrical hniav zoo.
