Intshukumo yesixhobo sokulawula ixesha lemoto.
Izixhobo zexesha zingeniswa kwiinkqubo zokungenisa kunye nokukhupha kwiinjini zokutsha zangaphakathi, kwiiwashi kunye nezinye iinkqubo zendawo ezinobudlelwane obulandelelanayo ukugqiba imisebenzi yomatshini.
Iindlela ezintathu zothumelo lwegiya lexesha: ityathanga lokuqhuba, ibhanti lezinyo lokuqhuba, igiya yokuqhuba.
Iigiya ezilungileyo nezingalunganga ze-injini yemoto ziqhutywa yibhanti enamazinyo, enezibonelelo zesakhiwo esilula, ingxolo ephantsi, ukusebenza kakuhle, ukuchaneka okuphezulu kokuhanjiswa, ulungelelwaniso oluhle, njl., kodwa amandla ayo aphantsi, kwaye kulula ukuwenza. ubudala, ukolula deformation okanye ukwaphuka emva kokusetyenziswa ixesha elide. Ibhanti yamazinyo ikwimeko evaliweyo kwi-cover yangaphandle, engafanelekanga ukujonga imeko yayo yokusebenza. Kukho imoto Mitsubishi, akukho iimpawu isiqalo, emva ioli, uphando sesekethe, impazamo kusekho, kwaye ke uvule ikhava yegumbi valve, wafumanisa ukuba ingalo yevalve rocker ayisebenzi, uzimisele ukuba ibhanti izinyo ixesha laphukile. Emva kokutshintshwa kwemveliso entsha, injini ayisayi kuqalisa. Ngenxa yokuba, xa ibhanti lezinyo liphukile ekusebenzeni, i-camshaft iyayeka ukusebenza, kwaye i-crankshaft iya kuqhubeka ijikeleza i-Angle ethile okanye inani lokujika phantsi kwesenzo sokujikeleza kwe-inertia ye-flywheel okanye inertia yesixhobo sokuhambisa. Ngeli xesha, i-injini ayikwazi ukusebenza, kwaye ngakumbi, isigaba sevalve sitshabalalisiwe, kwaye ipiston iya kugoba intonga yevalve kwindawo evulekileyo, okukhokelela ekubeni ivalve ivalwe ngokukhululekileyo. Ke ngoko, ezinye iinjini ezinamabhanti anamazinyo aphukileyo, nokuba uphawu lwegiya lwexesha luphinde lwalungiswa, kwaye ibhanti lexesha elitsha lamazinyo litshintshwa, injini ayikabi lula ukuyiqalisa, okanye kunzima ukuyiqala, kodwa umsebenzi awuqhelekanga. , kunye nesenzeko "sokucaphuka", "ukudubula", amandla angonelanga, kunye nomsindo owandayo. Kule meko, kuphela ngokususa intloko ye-cylinder kunye nokutshintsha i-valve inokuthi imeko yobugcisa be-injini ibuyiselwe ngokupheleleyo. Umzuzu kunye nemeko yesenzo se-valve kufuneka ihambelane nemeko kunye nexesha lokuhamba kwepiston, kwaye i-crankshaft kunye ne-camshaft ayikho kwi-axis, kufuneka zidibaniswe yinkqubo yokuhambisa, inkqubo yokuhambisa igqityiwe. ngamagiya amabini kunye nekhonkco okanye ibhanti, ke iigiya ezimbini zibizwa ngokuba zizixhobo zexesha, iigiya ezimbini ziphawulwe, Emva kokufaka ikhonkco okanye ibhanti ngokophawu, kunokuqinisekisa ukuba umzuzu kunye nesenzo sesenzo sevalve sichanekile.
Umsebenzi wesigqubuthelo sesixhobo sexesha kukukhusela igiya yexesha kuthuli kunye namanzi. Indima yesixhobo sexesha kukubeka isikali sexesha lokugqitywa kwemisebenzi yokulawula efanelekileyo kwisixhobo somatshini.
Isixhobo sexesha sisixhobo esidlala indawo yesikali sexesha lokugqitywa kwemisebenzi yolawulo efanelekileyo kwisixhobo somatshini. Izixhobo zexesha zingeniswa kwiinkqubo zokungenisa kunye nokukhupha kwiinjini zokutsha zangaphakathi, kwiiwashi kunye nezinye iinkqubo zendawo ezinobudlelwane obulandelelanayo ukugqiba imisebenzi yomatshini.
Indima yesixhobo sexesha: inokudlala indima yokubeka isikali sexesha ekugqityweni kwemisebenzi yokulawula efanelekileyo kwisixhobo somatshini.
Iindlela ezintathu zothumelo lwegiya lexesha: ityathanga lokuqhuba, ibhanti lezinyo lokuqhuba, igiya yokuqhuba. Iigiya ezilungileyo nezingalunganga ze-injini yemoto ziqhutywa yibhanti enamazinyo, enezibonelelo zesakhiwo esilula, ingxolo ephantsi, ukusebenza kakuhle, ukuchaneka okuphezulu kokuhanjiswa, ulungelelwaniso oluhle, njl., kodwa amandla ayo aphantsi, kulula ukuguga, ukuxinezeleka. i-deformation okanye i-fracture emva kokusetyenziswa kwexesha elide, kwaye akulula ukujonga imeko yayo yokusebenza.
Umzuzu kunye nemeko yesenzo sevalve kufuneka ihambelane nemeko kunye nomzuzu wokuhamba kwepiston, kwaye i-crankshaft kunye necamshaft azikho kwi-axis, kwaye kufuneka kubekho inkqubo yokuhambisa phakathi kwabo ukudibanisa, inkqubo yokuhambisa. igqitywe ngamagiya amabini kunye netyathanga okanye ibhanti, ke ezi zimbini zibizwa ngokuba ziigiya zexesha.
Ukusilela kwesixhobo sexesha le-injini yemoto
Xa injini isebenza, yenza isandi esiqhubekayo okanye esinesingqi ngaphambili enjinini. Kwiimeko eziqhelekileyo, isantya esiphezulu, isandi esikhulu; Isandi asitshintshi xa ubushushu buguquka; Isandi sokuqhekeka komlilo omnye asipheli.
Izizathu ezinokwenzeka zesandi esingaqhelekanga sesixhobo sexesha
(1) Umsantsa womdibaniso wegiya mkhulu kakhulu okanye umncinci kakhulu
(2) Umgama osembindini phakathi komngxunya ongundoqo we-crankshaft kunye ne-camshaft ephethe umngxuma utshintsha ngexesha lokusetyenziswa okanye ulungiso, ube mkhulu okanye ube mncinci; Imigca esembindini yekrankshaft kunye necamshaft ayihambelani, okukhokelela ekudakaleni kakubi kweegiya.
(3) Ubume bezinyo lwegiya alucutshungulwanga, i-deformation ngexesha lokunyanga ubushushu okanye indawo yezinyo igugile kakhulu;
(4) I-gap yokukrazula ayiqinile okanye ukusika kweengcambu kwenzeka ngexesha lokujikeleza kwegiya;
(5) umphezulu wezinyo uneziva, ukubola okanye ukwaphuka kwamazinyo;
(6) Isixhobo sikhululekile okanye siphumile kwi-crankshaft okanye kwi-camshaft;
(7) igiya yokujongana nesetyhula okanye ukuphuma kweradial kukhulu kakhulu;
(8) i-crankshaft okanye i-camshaft axial clearance inkulu kakhulu;
(9) Iigiya azitshintshwa zibe ngazibini.
(10) Emva kokutshintsha i-crankshaft kunye ne-camshaft ethwele isihlahla, indawo yokuhlangana kwegiya iyatshintshwa.
(11) i-camshaft ye-timing gear yokulungisa i-nut ikhululekile.
(12) i-camshaft yexesha lokulahlekelwa kwezinyo, okanye ukugqabhuka kwe-radial.
Isixhobo sexesha iimpawu zesandi esingaqhelekanga
1) Isandi sinzima ngakumbi, ngamanye amaxesha sinesingqisho, ngamanye amaxesha asikho isingqisho, ngamanye amaxesha siphakathi, ngamanye amaxesha siyaqhubeka.
2) Xa i-injini ingasebenzi okanye isantya sitshintsha, kukho ingxolo encinci kunye nencinci kwisigqubuthelo segumbi legiya ngexesha, kwaye ingxolo iyanyamalala emva kokuba isantya sonyuswe, kwaye ingxolo ibonakala xa injini iyancipha ngokukhawuleza. .
I-3) Ezinye izandi azichatshazelwa yiqondo lokushisa kunye novavanyo olulodwa lwe-cylinder fire break, kwaye ezinye zichaphazelekayo yiqondo lokushisa, akukho sandi xa iqondo lokushisa liphantsi, kwaye xa iqondo lokushisa liphakama ngokuqhelekileyo, isandi sibonakala.
4) Ezinye izandi zikhatshwa kukungcangcazela kwesigqubuthelo segumbi lezixhobo zexesha, kwaye ezinye izandi azikhatshwa kukungcangcazela.
