Cov saw hlau yog ib qho tseem ceeb tshaj plaws ntawm lub tsheb kauj vab. Nws yog lub luag haujlwm rau kev hloov lub zog los ntawm cov pedals mus rau lub log tom qab, ua rau lub tsheb kauj vab txav mus tom ntej. Tab sis koj puas tau xav paub tias muaj pes tsawg lub rollers feem ntau siv rau cov saw hlau tsheb kauj vab?
Hauv ntiaj teb tsheb kauj vab, cov saw hlau raug faib ua pawg los ntawm qhov siab, uas yog qhov deb ntawm cov pins sib law liag. Kev ntsuas qhov siab ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab qhov sib xws ntawm cov saw hlau nrog cov sprockets thiab cov saw hlau.
Cov saw hlau uas siv ntau tshaj plaws rau tsheb kauj vab yog 1/2 nti pitch saw. Qhov no txhais tau tias qhov deb ntawm nruab nrab ntawm ob lub pins roller sib law liag yog ib nrab nti. 1/2 nti pitch saw hlau siv dav hauv kev lag luam tsheb kauj vab vim lawv sib xws nrog ntau yam khoom siv drivetrain thiab lawv yooj yim siv.
Txawm li cas los xij, nws tsim nyog sau tseg tias cov saw hlau tsheb kauj vab muaj qhov dav sib txawv, uas tuaj yeem cuam tshuam rau lawv qhov sib xws nrog cov iav sib txawv. Qhov dav dav tshaj plaws rau cov saw hlau tsheb kauj vab yog 1/8 nti thiab 3/32 nti. Cov saw hlau 1/8″ feem ntau yog siv rau ntawm ib qho ceev lossis qee lub tsheb kauj vab iav ruaj khov, thaum cov saw hlau 3/32″ feem ntau yog siv rau ntawm ntau lub tsheb kauj vab ceev.
Qhov dav ntawm cov saw hlau yog txiav txim siab los ntawm qhov dav ntawm cov sprockets thiab cov txuas. Cov tsheb kauj vab ib zaug ceev feem ntau siv cov saw hlau dav dua rau kev ruaj khov thiab kev ruaj khov. Cov tsheb kauj vab ntau ceev, ntawm qhov tod tes, siv cov saw hlau nqaim dua kom haum rau ntawm cov cogs sib nrug ze.
Tsis tas li ntawd xwb, tus naj npawb ntawm cov iav hauv koj lub tsheb kauj vab lub drivetrain kuj tseem tuaj yeem cuam tshuam rau hom saw hlau siv. Cov tsheb kauj vab ib zaug ceev feem ntau siv 1/8 nti dav saw hlau. Txawm li cas los xij, cov tsheb kauj vab nrog cov iav derailleur xav tau cov saw hlau nqaim dua kom haum rau kev hloov pauv ntawm cov iav. Cov saw hlau no feem ntau muaj cov qauv tsim nyuaj dua thiab yuav raug cim nrog cov lej xws li 6, 7, 8, 9, 10, 11 lossis 12 ceev los qhia lawv qhov sib xws nrog lub drivetrain tshwj xeeb.
Yuav kom ntseeg tau tias koj txoj saw hlau ua haujlwm tau zoo tshaj plaws thiab siv tau ntev, nws yog ib qho tseem ceeb uas yuav tsum xaiv txoj saw hlau kom raug rau koj lub tsheb kauj vab. Kev siv txoj saw hlau tsis sib xws yuav ua rau kev hloov pauv tsis zoo, hnav ntau dhau thiab ua rau cov khoom siv tsav tsheb puas tsuaj.
Yog li ntawd, nws yog ib qho tseem ceeb kom sab laj nrog cov lus qhia ntawm cov chaw tsim khoom lossis nrhiav kev qhia ntawm tus kws kho tsheb kauj vab thaum xaiv cov saw hlau hloov rau koj lub tsheb kauj vab. Lawv tuaj yeem pab koj txiav txim siab qhov dav ntawm cov saw hlau thiab tus lej ceev uas haum rau koj lub tsheb kauj vab lub zog.
Hauv kev xaus lus, hom saw hlau uas siv ntau tshaj plaws hauv cov saw hlau tsheb kauj vab yog 1/2 nti pitch saw hlau. Txawm li cas los xij, yuav tsum xav txog qhov dav ntawm saw hlau thiab kev sib haum xeeb nrog lub tsheb kauj vab lub iav. Kev xaiv cov saw hlau zoo ua kom muaj kev sib kis hluav taws xob du thiab zoo, ua rau muaj kev caij tsheb zoo dua.
