Isenzo senduku yokuxhuma ngaphambili kwemoto
Umsebenzi oyinhloko wenduku yokuxhuma ngaphambili kwemoto ukuguqula ukunyakaza okuphindaphindayo kwepiston kube ukunyakaza okuzungezisayo kwe-crankshaft, nokuguqula amandla asebenza ku-piston abe okukhiphayo kwe-torque ye-crankshaft, ngaleyo ndlela ukushayela isondo lemoto ukuze lijikeleze.
Ngokuqondile, induku yokuxhuma idlala indima ebalulekile enjinini:
Ukuxhuma i-piston kanye ne-crankshaft : Ingxenye eyodwa yenduku yokuxhuma ixhuma ipiston bese enye ixhuma i-crankshaft, ukuze ukunyakaza okuqondile kwepiston kuguqulwe kube ukunyakaza okujikelezayo kwe-crankshaft. Lokhu kuguqulwa kuyisisekelo ekusebenzeni kahle kwenjini, ngoba imoto idinga ukunyakaza okuzungezayo kwe-crankshaft ukuze ikhiphe amandla.
amandla okudlulisa : Induku yokuxhuma iphinde idlulisele amandla asebenza ku-piston ku-crankshaft, eguqulwa ibe yi-torque ye-crankshaft, ngaleyo ndlela ishayela amasondo emoto ukuze ajikeleze. Lokhu kudluliselwa kwamandla kuyinqubo eyinhloko ekuphumeni kwamandla enjini .
i-piston esekelayo : Induku yokuxhuma nayo idlala indima yokusekela ipiston ukuze kuqinisekiswe ukusebenza okuzinzile kwepiston kusilinda ngaphandle kokuzamazama noma ukucisha, ukuze kuqinisekiswe ukusebenza okuvamile kwenjini.
Ukugcinwa nokuhlola : Ukuze kuqinisekiswe ukusebenza okuvamile kwenduku yokuxhuma, kuyadingeka ukuhlola isimo senduku yokuxhuma njalo. Lokhu kuhlanganisa ukuhlola ukucinana kwamabholithi enduku yokuxhuma, ukuguga kwejenali kanye nezimbobo zamaphini e-piston, nokugcina ukugcotshwa okuhle, ukugwema umthelela wangaphandle, ukuhlola ibhalansi, njll.
Ngale misebenzi kanye nezinyathelo zokulungisa, ukusebenza okuvamile kwenjini yemoto kanye nokusebenza okuzinzile kwemoto kungaqinisekiswa.
Izinto eziyinhloko zenduku yokuxhuma ngaphambili kwemoto zifaka i-ductile iron, i-alloy steel, i-aluminium alloy kanye ne-titanium alloy. Ngayinye yalezi zinto inezinzuzo kanye nokungalungi futhi ifanele izimo zohlelo lokusebenza ezahlukene.
i-ductile iron : lena into esetshenziswa kakhulu injini yezimoto yokuxhuma, inamandla amakhulu nokuqina, ibiza kancane, ifanele izimoto ezijwayelekile.
insimbi ye-alloy : insimbi yokuxhuma insimbi inamandla aphakeme, ubulukhuni nokumelana nokugqokwa, kodwa izindleko ziphezulu, zilungele izimoto ezisebenza kahle kanye nemijaho.
ingxubevange ye-aluminium : i-aluminium ingxubevange exhuma induku isisindo sokukhanya, ukuqhutshwa kwe-thermal okuhle, isiza ukuthuthukisa ukusebenza kahle kukaphethiloli, kodwa amandla aphansi, alungele ukuphishekela izimoto ezingasindi kanye nezisebenza kahle kuphethiloli.
i-titanium alloy : induku yokuxhuma i-titanium alloy inamandla amakhulu, ukuminyana okuphansi kanye nokungagqwali okuhle, kodwa izindleko ziphezulu kakhulu, zilungele izimoto ezisezingeni eliphezulu nemijaho.
Ngaphezu kwalokho, induku yokuxhuma idinga ukupholishwa ngesikhathi somshini ukuze kuxazululwe izinkinga zekhwalithi ephezulu futhi kuthuthukiswe impilo yesevisi. Inqubo yokupholisha, okuhlanganisa ukubola, ukukhipha i-deoxidizing, nokususwa kwe-flash, ingenziwa kusetshenziswa umshini wokugaya odlidlizayo noma ophakathi nendawo.
