Momwe ma pulleys amagwirira ntchito
Pali mitundu iwiri ikuluikulu ya ma pulleys amagalimoto: ma crank pulleys ndi zowonjezera. Ma pulleys ambiri amayendetsedwa ndi crankshaft main pulley, yomwe imamangidwira ku crankshaft. Injini ikamathamanga, crank pulley imazungulira, kusuntha kupita ku zida zina kudzera pa lamba wa V-ribbed kapena V-belt.
Nthawi zina camshaft imakhala ndi mphamvu yochotsa mphamvu, ndi camshaft yolumikizidwa ndi crankshaft ndi malamba oyendetsedwa ndi sprocket kapena maunyolo. Pankhaniyi, zida zoyendetsedwa ndi camshaft pulley zimayendetsedwanso mwachindunji ndi crankshaft.
Momwe Pulley Amagwirira Ntchito
Pamene imodzi ya pulleys yowonjezera imazungulira chifukwa cha kayendetsedwe ka lamba woyendetsa galimoto, imapangitsa kuti chowonjezeracho chizitsegulidwa. Mwachitsanzo, kusuntha kwa pulley ya jenereta kumapangitsa mphamvu ya maginito kupanga, yomwe imasandulika kukhala magetsi, zomwe zimapangitsa kuti jenereta igwire ntchito. Pulley yowongolera mphamvu imakakamiza ndikuzungulira madzimadzi kuti kuyendetsa kumakhala kosavuta. Nthawi zambiri, injini ikathamanga, ma pulleys amayatsa zowonjezera. Komabe, pali zosiyana. Mwachitsanzo, kompresa yanu ya air conditioner ili ndi clutch yomangidwira kotero imazungulira momasuka ngakhale mulibe choyatsira mpweya.
Ma tensioner ndi idler roller ndi osiyana pang'ono. Salamulira zowonjezera kapena kupereka mphamvu. Pulley yapakatikati nthawi zina imatha kusintha chowonjezera, kapena kungophatikizidwa mu lamba wa serpentine, kupanga gawo la njira yovuta ya lamba. Ma pulleys awa si ovuta kwambiri - amangokhala ndi makina a cylindrical ndi kunyamula, ndipo akamazungulira, amazungulira momasuka. Ma tensioner roller amagwira ntchito mofananamo, koma amasunganso malamba olimba bwino. Amagwiritsa ntchito zitsulo zodzaza masika ndi zomangira kuti agwiritse ntchito bwino dongosolo.
Ichi ndi chithunzithunzi chosavuta cha ma pulleys a lamba m'galimoto yanu. Zomwe muyenera kudziwa ndikuti popanda makina ovuta a pulley pansi pa hood, galimoto yanu ikadapanda kuwongolera.
