Niaj hnub no kuv yuav qhia ob peb yam sib quas ntus motion mechanisms, feem ntau suav nrog: ratchet mechanism, sheave mechanism, cam intermittent motion mechanism, thiab tsis tiav iav mechanism.
1. Ratchet mechanism
Ib-txoj kev sib cuam tshuam cov lus tsa suab mechanism tsim los ntawm ratchet thiab pawl. Nws feem ntau muaj cov rocker, pawl thiab ib lub ratchet sab nraud. Lub rocker yog ib qho kev tawm tswv yim tawm tswv yim, thiab lub ratchet yog ib qho kev tawm suab.
Qhov zoo: Lub ratchet mechanism muaj cov qauv yooj yim, kev tsim khoom yooj yim thiab txhim khu kev qha, thiab lub kaum sab xis ntawm lub ratchet tuaj yeem hloov kho raws li qhov xav tau.
Disadvantages: Lub ratchet mechanism muaj me me kis tau tus mob thiab ua rau muaj kev cuam tshuam thiab suab nrov thaum ua haujlwm. Yog li ntawd, ratchet mechanism tsuas yog haum rau cov xwm txheej uas qhov kev sib hloov ceev tsis siab, lub kaum sab xis tsis loj, thiab lub zog qis.
2. Sheave mechanism
Lub tshuab sheave yog ib txoj kev sib tshuam sib cuam tshuam mechanism tsim los ntawm ib tug sheave thiab ib tug cylindrical tus pin, kuj hu ua Maltese mechanism. Nws yog feem ntau siv los hloov qhov kev sib hloov tas mus li ntawm qhov tsav tsheb mus rau hauv unidirectional periodic kev sib hloov ntawm qhov tsav nrog pauses.
Sheave mechanisms suav nrog sab nraud meshing, internal meshing, thiab spherical sheaves. Cov yam ntxwv ntawm lub sheave mechanism yog cov qauv yooj yim, txhim khu kev qha kev ua haujlwm thiab kev siv tshuab siab. Txawm li cas los xij, kev tsim khoom thiab kev sib dhos qhov yuav tsum tau muaj siab, thiab lub kaum sab xis tsis tuaj yeem hloov kho.

3. Tsis tiav iav mechanism
Lub iav tsis tiav yog ib qho kev sib tshuam ntawm kev hloov pauv ntawm lub iav mechanism. Tsuas yog ib tus hniav lossis ob peb tus hniav tsuas yog ua rau ntawm lub log tsav ntawm lub tshuab no, thiab raws li qhov xav tau ntawm lub sijhawm txav thiab lub sijhawm tsis sib xws, cov hniav yog tsim rau ntawm lub log tsav. Tus naj npawb ntawm cov iav hniav uas mesh nrog tsav iav hniav.
Cov iav tsis tiav muaj cov qauv yooj yim, yooj yim rau kev tsim khoom, thiab ua haujlwm ntseeg tau. Lub sijhawm txav mus los thiab lub sijhawm so ntawm lub log tsav tuaj yeem hloov pauv hauv qhov dav. Txawm li cas los xij, lub log tsav tau muaj kev cuam tshuam loj thaum nws pib nkag thiab tshem tawm, yog li nws feem ntau tsuas yog siv nyob rau hauv qis ceev thiab lub teeb load.

4. Cov iav tsis muaj vaj huam sib luag
Cov iav uas tsis yog lub voj voog tseem hu ua cov iav tshwj xeeb. Lawv yog cov iav nrog ib qho indexed curved nto es tsis yog ib tug rotating nkhaus nto. Tom qab nws tsim ib lub iav khub nrog lwm lub iav, thaum lub sij hawm meshing txheej txheem, nws instantaneous angular tshaj tawm piv hloov raws li ib qho kev cai lij choj tsim.
Cov iav tsis muaj vaj huam sib luag tau siv dav hauv ntau lub tshuab tshwj xeeb xws li cov cuab yeej siv hluav taws xob, cov cuab yeej daws teeb meem, tshuab luam ntawv, thiab cov tshuab textile kom ua tiav qee qhov kev xav tau lossis txhim kho cov lus tsa suab thiab cov yam ntxwv zoo.
