Chifukwa Chake Kusintha Lamba Nthawi Kungakhale Kovuta

Njira zosinthira lamba wanthawi zimasiyana malinga ndi mtundu wa lamba. Ntchito ndi kukonza ziyenera kuchitidwa motsatira malingaliro a wopanga.

Magalimoto ambiri ndi magalimoto opepuka amakhala ndi malamba oyendera nthawi. Injini zodutsa, zomwe zimadziwika kuti front wheel drive, zitha kukhala zachinyengo kuchotsa ndikusintha lamba wanthawi.

Pali mitundu itatu ya malamba a nthawi

• Lamba wanthawi yokhala ndi camshaft imodzi yokha
• Nthawi yokhala ndi ma camshaft awiri apamwamba
• Lamba wokhala ndi mano awiri okhala ndi ma camshaft awiri apamwamba

Lamba wanthawi yokhala ndi camshaft imodzi yokha

Kusintha lamba wanthawi yayitali wa kamera kungakhale ntchito yovuta. Magalimoto ena amakhala ndi mabulaketi, ma pulleys, kapena mapaipi ozizirira kutsogolo kwa chivundikiro cha nthawi. Kusunga camshaft ndi crankshaft pamzere ndikosavuta mukasintha lamba wanthawi.

Nthawi yokhala ndi ma camshaft awiri apamwamba

Malamba apawiri owongolera nthawi ya kamera amathanso kukhala ovuta. Magalimoto ambiri pamsika masiku ano ali ndi kapangidwe ka mutu wa silinda momwe sitima ya valve imalowa m'chipinda choyaka moto pakona ya madigiri makumi anayi mpaka makumi asanu ndi atatu. Izi ndizofunikira kwambiri pochotsa lamba wanthawi yake chifukwa cha kusanja kwa sitima ya valve. Lamba wanthawiyo akachotsedwa pa camshaft yapawiri, ma camshaft onse amadzazidwa ndi akasupe. Kamshaft imodzi ikhoza kukhala ndi shaft katundu, zomwe zimapangitsa kuti camshaft ikhalebe pamalo pomwe lamba amachotsedwa. Komabe, sipadzakhala katundu pa camshaft ina ndipo shaft idzazungulira pansi pa kuthamanga kwa masika. Izi zingapangitse kuti valavu igwirizane ndi pisitoni, zomwe zimapangitsa kuti valavu ikhale yopindika.

Pofuna kuteteza camshaft kuti isazungulire pamene lamba wa nthawi yake achotsedwa, chida chotsekera cha cam chiyenera kugwiritsidwa ntchito. Chida cha loko cha cam chimatseka ma camshaft onse ndikuwagwirizanitsa kuti asazungulira.

Lamba wokhala ndi mano awiri okhala ndi ma camshaft awiri apamwamba

Mtundu wovuta kwambiri wosinthira lamba wanthawi, ndipo ukhoza kukhala wovuta kwambiri kuchita, ndi lamba wapawiri wapawiri. Lamba wamtunduwu ndi lamba umodzi womwe umagwiritsidwa ntchito pamainjini osinthira av okhala ndi mitu iwiri ya camshaft. Ma injini ambiri a V-6 amatha kukhala ndi lamba wamtunduwu. Mukasintha lamba wamtunduwu, ndikofunikira kukhala ndi zida ziwiri zotsekera cam popeza pali mitu iwiri ya silinda pa injini.

Pa injini zopingasa, lamba wanthawiyo akhoza kukhala ovuta kuchotsa chifukwa cha malo ochepa oti apeze lamba. Pa magalimoto ena ndikosavuta kuchotsa lamba pamwamba pa injini, koma pamagalimoto ambiri magudumu ndi matayala amayenera kuchotsedwa ndi chotchinga chamkati ngati chatsekeredwa kuti apeze zotchingira zapansi. chivundikiro cha nthawi. Zophimba nthawi zambiri tsopano ndi chidutswa chimodzi, zomwe zimapangitsa kuchotsedwa kwa balancer ya harmonic yomwe ili pa crankshaft.

Pa injini zina, kukwera kwa injini kumasokoneza kuchotsa lamba wa nthawi ndikupangitsa kuti zikhale zovuta kuchotsa lamba. Pamenepa, kuthandizira injini ndi kuiletsa kuti isasunthe kumathandizira kuchotsa ndi kuyika zida za injini, zomwe zimadziwika kuti mafupa a galu.

Malamba a nthawi ayenera kusinthidwa malinga ndi malingaliro a wopanga. Kusintha lamba wanthawi kale kuposa nthawi zonse ndikotheka, koma osavomerezeka.

• Chenjerani: Ngati lamba wa nthawi wathyoka, onetsetsani kuti mwayang'ana injini kuti muwone ngati ili ndi phokoso kapena phokoso. Komanso, sinthani nthawi, ikani lamba watsopano, ndipo yesani kuyesa kutayikira kuti muwonetsetse kuti injiniyo ndiyoyenera kugwira ntchito bwino. AvtoTachki ili ndi ntchito zosinthira lamba wanthawi.
