Rau cov khoom siv tua hluav taws, txhua yam khoom siv ua lub luag haujlwm tseem ceeb hauv kev ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Ob yam tseem ceeb uas feem ntau siv hauv kev tiv thaiv hluav taws kub yog cov couplings nruj thiab hloov tau yooj yim couplings. Txawm hais tias lawv ua haujlwm zoo sib xws, lawv muaj cov yam ntxwv tshwj xeeb uas ua rau lawv sib nrug.
Lub coupling yog ib qho cuab yeej siv los txuas ob lub shafts ua ke, xa hluav taws xob los ntawm ib tus ncej mus rau lwm qhov. Hauv kev tiv thaiv hluav taws, cov pob qij txha yog siv los txuas cov kav dej uas nqa dej mus rau qhov chaw ntawm hluav taws. Rigid couplings, raws li lub npe qhia, muab kev sib txuas ruaj khov thiab ruaj khov ntawm ob lub shafts. Lawv feem ntau yog ua los ntawm cov hlau thiab xav tau kev sib raug zoo meej thaum lub sijhawm teeb tsa. Rigid couplings yog siv dav hauv kev tiv thaiv hluav taws uas tsis tas yuav txav los yog hloov tau yooj yim.
Flexible couplings, ntawm qhov tod tes, yog tsim los kom haum rau misalignment ntawm shafts thaum tseem xa hluav taws xob zoo. Lawv feem ntau yog ua los ntawm cov ntaub ntawv elastic, xws li roj hmab, thiab muaj qee qhov kev hloov pauv. Hauv kev tiv thaiv hluav taws, kev sib txuas yooj yim muaj qhov zoo ntawm qhov kev txav los yog kev vibration vim tias lawv tuaj yeem nqus kev poob siab thiab them nyiaj rau qhov tsis zoo.
Qhov sib txawv tseem ceeb ntawm kev sib txuas ua ke thiab hloov tau yooj yim yog lawv lub peev xwm los xa cov torque thiab haum rau kev txav mus los. Rigid couplings muab kev sib txuas nruj kom ntseeg tau qhov siab tshaj plaws torque kis tau tus mob, tab sis muaj kev txwv tsis pub dhau. Lawv feem ntau yog siv thaum cov axes zoo sib xws thiab txav tsis muaj kev txhawj xeeb. Cov couplings yooj yim, ntawm qhov tod tes, tso cai rau me ntsis misalignment thiab txav thaum tseem xa cov torque zoo. Lawv tsim nyog rau cov xwm txheej uas thermal expansion lossis vibration tuaj yeem tshwm sim, xws li kev tiv thaiv hluav taws kub nruab rau hauv cov tsev siab.
Hauv cov ntsiab lus, txawm tias ob qho tib si nruj thiab hloov tau yooj yim yog qhov tseem ceeb hauv kev tiv thaiv hluav taws, lawv sib txawv hauv lawv lub peev xwm kom haum rau kev txav mus los thiab tsis zoo. Rigid couplings muab kev ruaj ntseg thiab ruaj khov kev sib txuas thiab yog qhov zoo tshaj plaws uas tsis muaj kev txav los yog hloov tau yooj yim. Kev sib txuas tau yooj yim, ntawm qhov tod tes, yog tsim los them nyiaj rau kev sib raug zoo thiab kev txav mus los, ua kom muaj kev sib kis tau zoo nyob rau hauv cov xwm txheej zoo. Kev nkag siab txog qhov sib txawv ntawm cov couplings no yog qhov tseem ceeb rau kev xaiv cov khoom kom raug rau ib daim ntawv thov tiv thaiv hluav taws.
