Nyob rau hauv kev lag luam machinery thiab automation cov cuab yeej, txoj kev sib txuas ntawm motors thiab tsav shafts ncaj qha cuam tshuam rau kev ua hauj lwm efficiency, stability, thiab kev pab lub neej. Kev xaiv ib qho kev sib txuas tsim nyog yuav tsum tau xav txog cov yam ntxwv ntawm kev thauj khoom, kev txhim kho precision, kev saib xyuas yooj yim, thiab cov nqi them. Hauv qab no yog ob peb lub cev muaj zog tsav ncej kev sib txuas nrog rau lawv qhov zoo thiab qhov tsis zoo.
1. Kev sib txuas sib txuas
Couplings sawv cev rau ib qho ntawm cov kev sib txuas uas siv dav tshaj plaws ntawm cov motors thiab tsav shafts. Lawv lub luag haujlwm tseem ceeb yog xa cov torque thaum them nyiaj rau misalignment ntawm ob lub shafts (xws li radial, axial, lossis angular sib txawv). Raws li kev sib txawv ntawm cov qauv, cov couplings tuaj yeem raug cais raws li hauv qab no:
(1) Rigid Couplings

● Qhov tsis zoo:Cov khoom elastic degrade dhau sijhawm, yuav tsum tau hloov pauv raws sijhawm; qis dua torque kis tau tus mob ntau tshaj li nruj couplings.
(3) Universal Joint Couplings
● Cov yam ntxwv zoo:Pab kom loj angular deflection (15℃-45 degree) ntawm tus ntoo khaub lig-shaft lossis pob-thiab-socket mechanisms.
● Qhov zoo:Kho kom haum rau cov txheej txheem spatial complex, xws li hauv tsheb tsav tsheb lossis kev tsim kho tshuab.
● Qhov tsis zoo:Qhia kev sib hloov ceev ceev (yuav tsum tau siv ua ke rau kev them nyiaj); cov nqi kho mob siab dua.
2. Siv Tsav Tsheb
Hloov lub zog ntawm txoj siv sia (piv txwv li, V- txoj siv sia, txoj siv sia synchronous) thiab pulleys, tsim txoj kev sib txuas yooj yim.
● Qhov zoo:
◆ absorbs kev co thiab poob siab, haum rau ntev - kis tau tus mob (txog li ob peb meters).
◆ Siv txoj hlua khi thaum lub sij hawm dhau los tiv thaiv cov khoom siv; yooj yim txij nkawm.
● Qhov tsis zoo:
◆ Kev sib kis qis dua (kwv yees . 90%–95%); txoj siv sia hnav thiab ncab, yuav tsum tau ua kom lub sijhawm ntev.
◆ Thaum synchronous siv los tiv thaiv slippage, lawv xav tau siab installation parallelism.
3. Gear Connection
Fais fab kis tau los ntawm cov iav khub (spur, helical, los yog cab iav).
● Qhov zoo:
◆ Cov iav sib piv, kev ua haujlwm siab (txog 98%), thiab muaj peev xwm thauj khoom siab, tsim nyog rau cov ntawv thov hnyav -.
◆ Cov qauv tsim thiab lub neej ua haujlwm ntev (txog kaum txhiab teev nrog lubrication kom zoo).
● Qhov tsis zoo:
◆ High manufacturing precision yuav tsum thiab tus nqi kuj; iav meshing tuaj yeem tsim suab nrov thiab kev co.
◆ Yuav tsum tau lubrication tsis tu ncua thiab kev kho kom yooj yim.
4. Direct Flange Txuas
Lub cev muaj zog thiab cov khoom siv thauj khoom tau txuas ncaj qha los ntawm flange, feem ntau siv hauv kev tsim qauv xws li twj thiab kiv cua.
● Qhov zoo:
◆ High structural rigidity nrog kev sib kis efficiency mus txog 100%, tshem tawm cov kev poob nruab nrab.
◆ Yam tsawg kawg nkaus qhov yuav tsum tau muaj, haum rau siab -precision, siab- daim ntawv thov ceev (xws li, CNC tshuab cuab tam spindles).
● Qhov tsis zoo:
◆ Xav tau kev sib tw coaxial nruj heev ntawm lub cev muaj zog thiab kev thauj khoom, ua rau kev teeb tsa thiab kev ua haujlwm nyuaj.
◆ Tsis tuaj yeem them nyiaj rau qhov tsis raug; kev vibrations yuav ncaj qha mus rau lub cev muaj zog.
5. Sib nqus coupling
Ua kom tsis muaj - kis tau tus mob siv cov hlau nplaum ruaj khov lossis electromagnetic induction.
● Qhov zoo:
◆ Ua tiav kev sib cais ntawm kev vibration, xoom hnav, txij nkawm -dawb.
◆ Tolerates loj misalignment, haum rau corrosive los yog kaw ib puag ncig (xws li, tshuaj twj tso kua mis).
● Qhov tsis zoo:
◆ Txwv tsis pub muaj peev xwm kis tau tus mob; kub kub yuav ua rau demagnetization; tus nqi siab.
Cov lus pom zoo xaiv
● High- daim ntawv thov precision (piv txwv li, cov khoom siv semiconductor):Ua ntej qhov kev sib txuas tsis sib xws lossis kev sib txuas ncaj qha flange kom ntseeg tau tias kev sib kis rigidity.

● Ntev - kis tau tus mob (piv txwv li, conveyor kab):Siv cov tsav tsheb muab tus nqi zoo tshaj -kev ua tau zoo.
Kev txiav txim siab txog kev saib xyuas
● Tsis tu ncua tshuaj xyuas kev sib txuas; recalibrate yog hais tias sib txawv tshaj li tso cai txwv.
● Saib xyuas txoj siv tawv nruj thiab hnav kom tsis txhob ntog lossis tawg.
● Xyuas kom huv si lubrication rau iav kev sib txuas los tiv thaiv cov hniav nto pitting.
Hauv cov ntsiab lus, txoj kev sib txuas ntawm cov motors thiab tsav shafts yuav tsum muaj kev xav zoo raws li kev ua haujlwm tshwj xeeb. Nrog rau kev txhim kho thev naus laus zis, cov kev daws teeb meem tshiab (xws li, carbon fiber couplings, ntse sib nqus couplings) tau txais kev pom zoo nyob rau hauv siab -kawg daim ntawv thov, muaj peev xwm ntxiv ntsuas kev ua tau zoo thiab cov nqi xav tau yav tom ntej.
