Cylindrical ZogXam cov ntaub ntawv chaw tsim khoom, feem ntau yog siv rau parallel ncej muag khoom kis, yuav tsum muaj kev suav ua kom ntseeg tau tias kev ua tau zoo. Qhov tseem ceeb uas tsis yog xav txog suav nrog cov iav sib piv, lub suab seev, thiab cov hniav hniav suav. Lub iav piv, txiav txim siab los ntawm cov hniav ntawm tus naj npawb ntawm cov hniav ntawm lub iav tsav tsheb mus rau cov iav tsav, cuam tshuam rau cov ceev thiab lub zog ntawm cov kab ke.
Txhawm rau laij cov suab lub taub ntawm lub taub, siv cov qauv:
Lub suab diam = diametral pitch / tus naj npawb ntawm cov hniav
Qhov twg txoj kab sib txawv ntawm cov hniav ib nti ntawm lub iav lub taub. Lwm qhov kev suav tseem ceeb yog lub iav tus qauv, muab los ntawm:
Module = naj npawb ntawm cov hniav / suab lub taub
Kev xam raug ntawm tus hniav profile thiab spacing yog qhov tseem ceeb kom tiv thaiv cov teeb meem mahing thiab xyuas kom meej. Tsis tas li ntawd, tshuaj xyuas rau cov iav ua kom zoo thiab cov thaub qab yog qhov tseem ceeb los tswj kev ua tau zoo thiab thanevity. Cov kev suav no pab nyob rau hauv kev tsim qauv siv txiaj ntsig zoo, ruaj ruaj, thiab haum rau lawv cov ntawv thov.
Tus tub tuag tuagHelical zogZoo ib yam li cov spur gears tsuas yog hais tias cov hniav yog nyob rau ntawm cov hniav ntawm cov nqaj hlau.
Hniav lub zog yog ntau dua vim tias cov hniav ntev dua
Great nto tiv toj rau ntawm cov hniav tso cai rau cov iav iav kom muaj lub nra ntau dua li cov iav spur
Lub ntev ntawm kev sib cuag reducers qhov ua tau zoo ntawm cov iav iav cuam tshuam rau ib qho spur iav.
