Hauv kev yuav khoom ntawm cov khoom lag luam, qhov sib txawv ntawm qhov tseeb ob-kab chains thiab cuav ob-kab sprockets yog qhov tseem ceeb thiab ncaj qha cuam tshuam rau kev ua haujlwm ruaj khov thiab kev nyab xeeb ntawm cov khoom siv. Raws li ib feem tseem ceeb ntawm kev sib txuas lus, qhov tseeb ob-kab saw hlau ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm kev sib kis los ntawm kev sib raug zoo ntawm ob txoj hlua sib txuas, thiab tau siv dav hauv ntau hom kev thauj mus los. Txawm li cas los xij, qhov cuav ob-kab sprockets nyob rau hauv kev ua lag luam yog tiag tiag disguised li ib-kab chains. Cov khoom no tsis tsuas yog tsis tuaj yeem ua raws li cov hniav iav, tab sis kuj yooj yim ua rau cov saw hlau poob thiab tawg, uas ua rau muaj kev nyab xeeb.
Txhawm rau kom paub qhov txawv ntawm qhov tseeb thiab qhov tsis tseeb ntawm ob kab chains, koj yuav tsum xub saib xyuas qhov tsos. Qhov tshwm sim ntawm cov saw hlau ob-kab qhov tseeb yog qhov sib xws thiab puag ncig, thiab tsis muaj cov yas deformation tom qab cov saw yog khoov, thaum qhov tsis tseeb ob-kab kab sprocket yog ntxhib thiab tsis sib xws, thiab nws tsis yooj yim rau rebound tom qab khoov. Qhov thib ob, cov khoom siv yog qhov tseem ceeb. Qhov tseeb ob-kab saw yog ua los ntawm cov khoom siv zoo thiab muaj zog, uas yog hnav-tiv taus thiab deformation-resistant tom qab kev kho kub kub; thaum qhov cuav ob-kab sprocket tuaj yeem siv cov ntaub ntawv tsis zoo thiab hnav tau yooj yim. Thaum kawg, lub koob npe nrov npe tsis tuaj yeem raug ignored. Ob-kab chains ntawm cov npe niaj hnub raug tshuaj xyuas nruj me ntsis ua ntej tawm hauv lub Hoobkas, nrog rau kev tiv thaiv kev ua txhaum cai nruj thiab lav zoo; Cov khoom cuav thiab shoddy tsis muaj cov kev lees paub thiab nyiam cov neeg siv khoom los ntawm tus nqi kom zoo dua.
Txhawm rau kom muaj kev nyab xeeb ntawm kev siv ob-kab chains, nws raug nquahu kom ntxuav thiab tswj lawv tsis tu ncua, hloov cov saw hlau nyob rau lub sijhawm, thiab ib txwm yuav cov npe tsis tu ncua. Kev pabcuam lub neej ntawm ob-kab chains yog txwv, feem ntau 1 txog 2 xyoos, thaum lub sijhawm hnav yuav tsum tau kuaj xyuas tsis tu ncua thiab hloov lub sijhawm yog tias tsim nyog. Thaum yuav khoom, cov khoom lag luam nrog lub koob npe zoo thiab kev lees paub zoo yuav tsum tau muab qhov tseem ceeb kom tsis txhob yuav cov khoom lag luam qis vim yog kev ntshaw rau pheej yig, thiaj li ua kom muaj kev nyab xeeb thiab nyob deb ntawm kev nyab xeeb.
