Worm gears thiab bevel gears yog ob hom iav siv hauv ntau daim ntawv thov. Nov yog qhov sib txawv tseem ceeb ntawm lawv:
Qauv: Cov cab cab muaj cov kab mob cylindrical (ntsia hlau zoo li) thiab lub log uas muaj cov hniav hu ua worm iav. Cov kab mob muaj cov hniav helical uas koom nrog cov hniav ntawm cov kab mob cab. Ntawm qhov tod tes, bevel iav yog conical nyob rau hauv cov duab thiab muaj kev sib tshuam shafts. Lawv muaj cov hniav txiav rau ntawm lub khob hliav qab.
Kev taw qhia:Worm iavfeem ntau yog siv thaum lub tswv yim thiab cov zis shafts nyob rau ntawm txoj cai kaum rau ib leeg. Qhov kev npaj no tso cai rau siab iav piv thiab torque sib npaug. Bevel gears, ntawm qhov tod tes, yog siv thaum lub tswv yim thiab cov zis tawm shafts tsis yog sib npaug thiab sib tshuam ntawm ib lub kaum ntse ntse, feem ntau 90 degrees.
Kev ua tau zoo: Bevel iavfeem ntau ua tau zoo dua ntawm kev xa hluav taws xob piv rau cov kab mob cab. Cov kab mob cab muaj qhov zawv zawg ntawm cov hniav, ua rau muaj kev sib txhuam ntau dua thiab ua haujlwm qis dua. Qhov kev ua zawv zawg no tseem ua kom muaj cua sov ntau dua, xav tau ntxiv lubrication thiab txias.
Gear Ratio: Cov iav iav yog lub npe hu rau lawv cov iav sib piv siab. Ib qho pib cab iav tuaj yeem muab qhov sib piv txo qis, ua rau lawv tsim nyog rau cov ntawv thov uas yuav tsum tau txo qhov nrawm. Bevel gears, ntawm qhov tod tes, feem ntau muaj cov iav qis dua thiab siv rau kev txo qis qis lossis hloov pauv hauv kev coj ua.
Backdriving: Worm gears muaj qhov ntsuas tus kheej, txhais tau tias tus cab tuaj yeem tuav lub iav hauv txoj hauj lwm yam tsis muaj kev sib tsoo ntxiv. Cov cuab yeej no ua rau lawv zoo tagnrho rau cov ntawv thov uas nws yog qhov tseem ceeb los tiv thaiv kev tsav tsheb rov qab. Bevel gears, txawm li cas los xij, tsis muaj qhov cuam tshuam tus kheej thiab yuav tsum muaj kev sib tsoo sab nraud lossis kev xauv lub tshuab kom tiv thaiv kev rov qab.
Nyob rau hauv cov ntsiab lus, worm gears yog haum rau daim ntaub ntawv uas yuav tsum tau high gear ratios thiab self-locking peev xwm, thaum bevel gears yog siv rau kev hloov ncej cov lus qhia thiab muab lub zog kis tau tus mob. Qhov kev xaiv ntawm ob yog nyob ntawm cov kev cai tshwj xeeb ntawm daim ntawv thov, nrog rau qhov xav tau iav piv, efficiency, thiab kev ua haujlwm.
