Kulumikiza ndodo.
Ntchito yaikulu ya matailosi olumikizira ndodo ndi kulumikiza, kuthandizira ndikuyendetsa ndodo yolumikizira, pamene akuchepetsa kukangana ndi kuwonongeka pakati pa crankshaft ndi ndodo yolumikizira, kupirira kupsinjika kwakukulu komwe kumachitika panthawi yogwira ntchito ya injini, ndikuwonetsetsa kuti crankshaft ikhoza kuzungulira bwino.
Matailosi olumikizira ndodo ndi gawo lofunika kwambiri mu injini ya galimoto, amalumikiza pistoni ndi crankshaft, amasintha kayendedwe ka pistoni kukhala kayendedwe kozungulira ka crankshaft, ndikusamutsa mphamvu yogwira ntchito pa pistoni ku mphamvu yotulutsa ya crankshaft. Kapangidwe ka ma shingles a ndodo yolumikizira kumathandiza kuwonjezera mphamvu ya mafuta, motero kumawonjezera magwiridwe antchito ndi magwiridwe antchito a injini. Kuphatikiza apo, matailosi olumikizira ndodo amapiriranso kupsinjika kwakukulu komwe kumachitika panthawi yogwira ntchito ya injini, kuonetsetsa kuti crankshaft ikhoza kuzungulira mokhazikika. Zinthu zomwe zili mu matailosi olumikizira ndodo nthawi zambiri zimakhala kuphatikiza maziko a aluminiyamu ndi lead yamkuwa, yomwe imakhala ndi kukana bwino kuwonongeka komanso kutentha, ndipo imatha kukwaniritsa zosowa za injini ikagwira ntchito kwambiri. Pakupanga matailosi olumikizira ndodo, ukadaulo wopangira chitsulo cha bimetallic steel strip wa alloy ya aluminiyamu yokhala ndi chitsulo imagwiritsidwanso ntchito kuti ikhale yolimba komanso yodalirika.
Matailosi olumikizira ndodo amagwira ntchito yolumikiza, kuthandizira, ndi kuyendetsa mu makina olumikizira ndodo ya galimoto, ndipo malekezero awiriwa amalumikizidwa ndi ziwalo zogwira ntchito komanso zoyendetsedwa motsatana kuti atumize kuyenda ndi mphamvu. Mwachitsanzo, mu makina olumikizirana a pistoni ndi ma compressor, ndodo yolumikizira imagwiritsidwa ntchito kulumikiza pistoni ku crank, kusintha kayendedwe kobwerezabwereza ka pistoni kukhala kayendedwe kozungulira ka crank. Ndodo yolumikizira nthawi zambiri imapangidwa ndi zigawo zachitsulo, gawo lalikulu la gawo lopingasa nthawi zambiri limakhala lozungulira kapena looneka ngati I, pali mabowo mbali zonse ziwiri, mabowo ali ndi bushing ya bronze kapena singano zozungulira, kuti zinyamule pini ya shaft kuti ipange articulation.
Mwachidule, kumvetsetsa ndi kudziwa bwino ntchito ndi mfundo ya matailosi olumikizira ndodo kumatithandiza kumvetsetsa bwino mfundo yogwirira ntchito ndi kapangidwe ka injini zamagalimoto, ndikuwonjezera magwiridwe antchito okonza ndi kukonza magalimoto.
Kaya matailosi olumikizira ndodo ndi akulu kapena ang'onoang'ono
matailosi
Matailosi a ndodo yolumikizira ndi matailosi ang'onoang'ono. Mu injini ya galimoto, kukula kwa matailosi nthawi zambiri kumatanthauza matailosi oyendetsera galimoto, omwe matailosi akuluakulu amatanthauza matailosi a crankshaft, ndipo matailosi ang'onoang'ono ndi matailosi a ndodo yolumikizira. Matailosi a ndodo yolumikizira amatchedwa matailosi ang'onoang'ono chifukwa amalumikizidwa ndi ma diameters opyapyala a ndodo yolumikizira. Mabearing awa amapangidwa ndi chitsulo cholimba kwambiri chomwe sichimawonongeka, chogawidwa m'zigawo ziwiri zapamwamba ndi zapansi, zomwe zimayikidwa mu crankshaft ndi thupi la silinda, cholumikizira ndodo ndi cholumikizira cha crankshaft. Ntchito yayikulu ya matailosi a ndodo yolumikizira ndi kusunga mawonekedwe osalala mu injini ndikuthandizira ku crankshaft ya injini kudzera mu kapangidwe ka sliding friction.
Kodi matailosi olumikizira ndodo ndi otani?
Zipangizo zolumikizira matailosi zimaphatikizapo mkuwa, bronze, aluminiyamu, white alloy (babbitt) ndi zina zotero.
Aloyi wopangidwa ndi mkuwa: Ndodo yolumikizira imapangidwa ndi zinthu zopangidwa ndi mkuwa zokhala ndi mphamvu yolimba yonyamula katundu, ndipo pamwamba pa chipolopolo chonyamula katundu chimakutidwa ndi electroplated ndi wosanjikiza woletsa kusweka kuti chiwonjezere mphamvu yake yonyamula katundu komanso kukana kukangana. Kuphatikiza apo, makulidwe a khoma la chipolopolo chonyamula katundu chimagwiritsa ntchito ukadaulo wochepetsa matailosi kuti filimu yamafuta ya chipolopolo chonyamula katundu ikhale yofanana kwambiri panthawi yogwira ntchito ya injini ndikuteteza chipolopolo chonyamula katundu kuti chisasweke.
Bronze: Zipangizo za shingles zolumikizira ndodo zimaphatikizapo bronze, yomwe ndi chinthu chosatha kutha chomwe chimagwiritsidwa ntchito kuchepetsa kutha pakati pa mutu wa ndodo yolumikizira ndi buku la ndodo yolumikizira. Bronze ili ndi kutha kutha kutha komanso kusinthasintha, ndipo imatha kusunga magwiridwe antchito okhazikika m'malo otentha kwambiri komanso opanikizika kwambiri.
Maziko a aluminiyamu: Ma shingles olumikizira ndodo amaphatikizaponso kugwiritsa ntchito zipangizo za maziko a aluminiyamu, zomwe zimakhala ndi kukana kwabwino kwa kuwonongeka komanso kusinthasintha kuti zikwaniritse zofunikira kwambiri pakugwira ntchito kwa injini.
Chotsulo choyera (Babbitt): Mbali yakunja ya thailo yolumikizira, makamaka mkati, nthawi zambiri imapangidwa ndi chotsulo choyera (chotsulo cha polymetallic chokhala ndi tin ndi lead). Chotsulo choyera, chomwe chimadziwikanso kuti chotsulo cha babbitt, ntchito yake yayikulu ndi yofewa, yopaka mafuta komanso yosatha, zomwe zimathandiza kuchepetsa kukhudzana mwachindunji pakati pa zitsulo ndikuchepetsa kuwonongeka.
Mwachidule, kusankha zinthu za ma shingles a ndodo yolumikizira kwapangidwa kuti kupereke kukana kwabwino kwa kuwonongeka, kukana kutentha kwambiri komanso magwiridwe antchito ogwirizana ndi malo ovuta ogwirira ntchito a injini.
Ngati mukufuna kudziwa zambiri, pitirizani kuwerenga nkhani zina patsamba lino!
Chonde tiimbireni foni ngati mukufuna zinthu zotere.
Zhuo Meng Shanghai Auto Co., Ltd. yadzipereka kugulitsa zida zamagalimoto za MG&MAUXS zomwe zikulandiridwa kugula.
