Isenzo senduku yokuxhumanisa engaphambili yemoto
Umsebenzi oyinhloko wenduku yokuxhumanisa yangaphambili yemoto ukuguqula ukunyakaza okulandelanayo kwepiston kube ukunyakaza okujikelezayo kwe-crankshaft, nokuguqula amandla asebenza ku-piston abe umphumela we-torque we-crankshaft, ngaleyo ndlela kushukumise isondo lemoto ukuthi lijikeleze .
Ngokuqondile, induku yokuxhuma idlala indima ebalulekile enjinini:
I-piston exhumanisayo kanye ne-crankshaft : Ukuphela kwenduku exhumanisayo kuxhuma i-piston kanti okunye ukuqeda kuxhuma i-crankshaft, ukuze ukunyakaza okuqondile kwe-piston kuguqulwe kube ukunyakaza okujikelezayo kwe-crankshaft. Lokhu kuguqulwa kubalulekile ekusebenzeni kahle kwenjini, ngoba imoto idinga ukunyakaza okujikelezayo kwe-crankshaft ukuze ikhiphe amandla .
Amandla okudlulisa : Induku yokuxhuma iphinde idlulisele amandla asebenza ku-piston iye ku-crankshaft, eguqulwa ibe yi-torque ye-crankshaft, ngaleyo ndlela iqhube amasondo emoto ukuthi ajikeleze. Lokhu kudluliselwa kwamandla kuyinqubo ebalulekile ekukhishweni kwamandla enjini .
I-piston esekelayo: Induku yokuxhuma idlala indima yokusekela i-piston ukuqinisekisa ukusebenza okuzinzile kwe-piston kusilinda ngaphandle kokunyakazisa noma ukuvala, ukuze kuqinisekiswe ukusebenza okuvamile kwenjini.
Ukugcinwa nokuhlolwa: Ukuze kuqinisekiswe ukusebenza okuvamile kwenduku yokuxhuma, kubalulekile ukuhlola isimo senduku yokuxhuma njalo. Lokhu kuhlanganisa ukuhlola ukuqina kwamabholti enduku yokuxhuma, ukuguguleka kwemigodi ye-jenali kanye ne-piston pin, nokugcina ukugcotshwa okuhle, ukugwema ukuthinteka kwangaphandle, ukuhlola ibhalansi, njll.
Ngale misebenzi kanye nezinyathelo zokulungisa, ukusebenza okuvamile kwenjini yemoto kanye nokusebenza okuzinzile kwemoto kungaqinisekiswa.
Izinto eziyinhloko zenduku yokuxhumanisa imoto ngaphambili zifaka insimbi ethambile, insimbi ehlanganisiwe, i-aluminium alloy kanye ne-titanium alloy . Ngayinye yalezi zinto inezinzuzo kanye nokungalungi futhi ifanelekela izimo ezahlukene zokusetshenziswa.
insimbi ethambile: lena yinto esetshenziswa kakhulu yokuxhuma injini yezimoto, inamandla aphezulu nokuqina, inezindleko eziphansi, ifanele izimoto ezijwayelekile.
Insimbi ye-alloy: induku yokuxhuma yensimbi ye-alloy inamandla aphezulu, ubulukhuni kanye nokumelana nokuguguleka, kodwa izindleko ziphakeme, zifanele izimoto ezisebenza kahle kanye nomjaho.
I-aluminium alloy : induku yokuxhuma i-aluminium alloy isisindo esilula, ukuhanjiswa okuhle kokushisa, kusiza ukuthuthukisa ukusebenza kahle kukaphethiloli, kodwa amandla aphansi, afanelekela ukuphishekela izimoto ezilula nezokusebenzisa kahle uphethiloli .
I-alloy ye-titanium: Induku yokuxhuma i-alloy ye-titanium inamandla aphezulu, ukuminyana okuphansi kanye nokumelana okuhle nokugqwala, kodwa izindleko ziphezulu kakhulu, zifanele izimoto ezisebenza kahle kakhulu kanye nezimoto zomjaho.
Ngaphezu kwalokho, induku yokuxhuma idinga ukupholishwa ngesikhathi sokucubungula ukuze kuxazululwe izinkinga zekhwalithi yobuso futhi kuthuthukiswe impilo yesevisi. Inqubo yokupholishwa, okuhlanganisa ukususa amalahle, ukususa i-oxidizing, kanye nokususwa kwe-flash, ingenziwa kusetshenziswa umshini wokugaya odlidlizayo noma we-centrifugal.
