Zizindikiro za Pulley Yolakwika kapena Yolakwika
Zizindikiro zodziwika bwino zimaphatikizapo chimbalangondo chowonongeka kapena pulley, kufinya m'dera lamagalimoto, ndi ma pulleys owoneka bwino.
Ma pulleys apakatikati ndi ma pulleys a injini omwe ali ndi udindo wowongolera ndi kumangirira malamba oyendetsa injini. Malamba oyendetsa injini amayendetsedwa mozungulira magawo osiyanasiyana a injini monga alternator, pampu yamadzi, pampu yowongolera mphamvu, ndi kompresa yowongolera mpweya mwanjira inayake. Pulley ya idler idapangidwa kuti iperekenso mfundo ina yozungulira yosalala lamba wamoto kuti njira yomwe mukufuna ifike. Mainjini ambiri amagwiritsa ntchito munthu wachabechabe m'modzi komanso wosagwira ntchito m'modzi, ngakhale kuti mapangidwe ena amagwiritsa ntchito anthu ocheperapo. M'kupita kwa nthawi, osagwira ntchito amatha ndipo amafunika kusinthidwa. Kawirikawiri pulley yoipa kapena yolakwika imayambitsa zizindikiro zingapo zomwe zingadziwitse dalaivala ku vuto.
1. Zovala zowoneka bwino
Chimodzi mwa zizindikiro zoyamba za vuto ndi pulley yosasamala ndi kuvala kowonekera pa pulley. M'kupita kwa nthawi, pamene pulley imazungulira pafupi ndi lamba, zigawo zonsezi zimayamba kuwonongeka. Izi zitha kuyambitsa zikwapu zowoneka pamwamba pa pulley chifukwa cholumikizana ndi lamba. Pakapita nthawi, pulley ndi lamba amavala mpaka kukangana kumachepetsedwa, zomwe zingayambitse lamba.
2. Kulira kwa lamba
Chizindikiro china chodziwika bwino chavuto lomwe lingakhale lopanda ntchito ndi malamba a injini. Ngati pamwamba pa pulley yongogwira ntchito yatha kapena kapuyo agwira kapena kugwidwa, izi zingapangitse lamba wa injini kufuula pamene akugwedeza pamwamba pa pulley. Nthawi zina, pulley yolephera imatha kumangirira kapena kutsetsereka, zomwe zimapangitsa kuti lamba aziwombera injini ikayamba. Vutoli lidzafika poipa kwambiri pamene pulley ikupitiriza kutha.
3. Kuwonongeka konyamula kapena pulley.
Chizindikiro china, chodziwika bwino cha vuto la pulley ndi kuvulazidwa kwa bere kapena pulley. Zikavuta kwambiri, kunyamula kapena pulley yokha imatha kuvala mpaka kusweka kapena kusweka, kugwa, kapena kugwidwa. Izi zikhoza kusokoneza kuzungulira kwa lamba ndikuyambitsa mavuto amtundu uliwonse. Pulley yothyoka kapena yogwidwa ingapangitse lamba kuthyoka mwamsanga kapena, m'malo ovuta kwambiri, lamba kutuluka mu injini. Injini yopanda lamba imatha kukumana ndi zovuta monga kutenthedwa ndi kuyimilira, chifukwa ndi lamba woyendetsa yemwe amathandizira zida za injiniyo.
Ma Idler pulleys ndi gawo lodziwika bwino pamagalimoto ambiri amsewu omwe pamapeto pake amafunikira kusinthidwa, makamaka pamagalimoto okwera kwambiri. Mapuleti aliwonse a injini ndi ofunika kwambiri pa ntchito yonse ya injini, chifukwa ndi lamba wa V-ribbed ndi ma pulleys omwe amalola injini kugwira ntchito bwino itatha. Ngati mukuganiza kuti pulley yanu yapakatikati ikhoza kukhala ndi vuto, khalani ndi katswiri waluso, monga "AvtoTachki", fufuzani galimotoyo kuti mudziwe ngati pulley iyenera kusinthidwa.
