Isenzo senduku yokuxhuma.
Iqhaza eliyinhloko lethayela lenduku yokuxhuma ukuxhuma, ukusekela nokushayela induku yokuxhuma, kuyilapho kunciphisa ukungqubuzana nokuguga phakathi kwe-crankshaft nenduku yokuxhuma, ukumelana nokucindezela okukhulu okukhiqizwa ngesikhathi sokusebenza kwenjini, nokuqinisekisa ukuthi i-crankshaft iyakwazi ukuzungeza. ngokuzinza.
Ukuxhuma i-rod tile kuyingxenye ebalulekile enjinini yemoto, baxhuma i-piston ne-crankshaft, baguqule ukunyakaza okuphindaphindayo kwe-piston ekunyakazeni okujikelezayo kwe-crankshaft, futhi badlulisele amandla asebenza ku-piston emandleni okukhipha i-crankshaft. Ukwakhiwa kwe-shingles yenduku yokuxhuma kusiza ukwandisa umphumela wokugcoba kawoyela, ngaleyo ndlela kuthuthukiswe ukusebenza kahle nokusebenza kwenjini. Ngaphezu kwalokho, amathayela enduku yokuxhuma aphinde amelane nokucindezela okukhulu okukhiqizwa ngesikhathi sokusebenza kwenjini, okuqinisekisa ukuthi i-crankshaft ingaba ukuzungezisa okuzinzile. Impahla ye-tile yenduku yokuxhuma ngokuvamile iyinhlanganisela yesisekelo se-aluminium kanye ne-copper lead, enokumelana okuhle kokugqoka kanye ne-thermal conductivity, futhi ingahlangabezana nezidingo zenjini ekusebenzeni komthwalo ophezulu. Enqubweni yokukhiqiza yokuxhuma amathayili wenduku, ubuchwepheshe bokucubungula i-bimetallic steel strip yensimbi-backed composite high tin aluminium base alloy nayo isetshenziselwa ukuthuthukisa ukuqina nokuthembeka kwayo.
I-tile yenduku yokuxhuma idlala indima yokuxhuma, ukusekela nokushayela kumshini wokuxhuma wemoto, futhi iziphetho ezimbili zincike kumalungu asebenzayo naqhutshwayo ngokulandelanayo ukuze adlulise ukunyakaza namandla. Isibonelo, emishinini yamandla e-piston ephindaphindayo kanye nama-compressor, induku yokuxhuma isetshenziselwa ukuxhuma i-piston ku-crank, ukuguqula ukunyakaza okuphindaphindayo kwepiston kube ukunyakaza okujikelezayo kwe-crank. Induku yokuxhuma ngokuvamile yenziwe ngezingxenye zensimbi, ingxenye eyinhloko yesigaba sesiphambano ngokuvamile iyindilinga noma i-I-shape, kunezimbobo emikhawulweni yomibili, imigodi ifakwe i-bronze bushing noma i-needle roller bearings, yokulayisha iphinikhodi ye-shaft yakha i-articulation.
Ngamafuphi, ukuqonda nokufunda indima kanye nomgomo wokuxhuma amathayela wezinduku kusisiza ukuba siqonde kangcono isimiso sokusebenza kanye nesakhiwo sezinjini zezimoto, futhi sithuthukise ukusebenza kahle kokukhanda nokugcinwa kwemoto.
Ukuthi i-tile yenduku yokuxhuma inkulu noma incane
ithayela
I-tile yenduku yokuxhuma iyithayela elincane. Enjini yezimoto, ubukhulu bethayili ngokuvamile bubhekisela kuthayela elithwalayo, lapho i-tile enkulu ibhekisela ku-tile ye-crankshaft, kanti i-tile encane iyi-tile yenduku yokuxhuma. Amathayela enduku yokuxhuma abizwa ngokuthi amathayela amancane ngoba axhunywe kumadayamitha enduku yokuxhuma emincane. Lawa ma-bearings enziwe ngensimbi ekwazi ukumelana nokuqina kokuqina, ihlukaniswe yaba izingcezu ezimbili ezingenhla neziphansi, ngokulandelana zifakwe ku-crankshaft nomzimba we-cylinder, induku yokuxhuma kanye nokuxhumeka kwe-crankshaft. Umsebenzi oyinhloko wethayela lenduku yokuxhuma ukugcina isimo sokusebenza kahle enjinini futhi sinikele ku-crankshaft yenjini ngokusebenzisa isakhiwo sokuslayida.
Iyiphi impahla ehlanganisa i-tile yenduku
Izinto zokuxhuma i-tile yenduku ikakhulukazi zihlanganisa i-copper base alloy, ithusi, isisekelo se-aluminium, i-alloy emhlophe (i-babbitt) njalonjalo.
Ingxubevange ye-Copper-base: Induku yokuxhuma yenziwe nge-copper-base alloy material enamandla okuthwala aqinile, futhi indawo engaphakathi yegobolondo elithwalayo ifakwe i-electroplated nge-anti-wear layer ukuze ithuthukise amandla ayo okuthwala kanye nokumelana nokungqubuzana. Ngaphezu kwalokho, ubukhulu bodonga lwegobolondo elithwalayo buthatha ubuchwepheshe bokunciphisa i-tile ukwenza ifilimu yamafutha yegobolondo elithwalayo ibe yinto efanayo ngesikhathi sokusebenza kwenjini futhi ivikele igobolondo elithwalayo ekugqokeni.
I-bronze: Impahla yama-shingles wenduku yokuxhuma ihlanganisa ithusi, okuyimpahla engagugi esetshenziselwa ukunciphisa ukuguga phakathi kwekhanda lenduku yokuxhuma kanye nejenali yenduku yokuxhuma. I-bronze inokumelana okuhle nokuguquguquka, futhi ingagcina ukusebenza okuzinzile ekushiseni okuphezulu nasezindaweni ezinengcindezi ephezulu.
Isisekelo se-Aluminium: Ukuxhuma ama-shingles wenduku kuhlanganisa nokusetshenziswa kwezinto eziyisisekelo ze-aluminium, ezinokumelana okuhle kokugqoka nokuvumelana nezimo ukuze zihlangabezane nezidingo eziphezulu zokusebenza kwenjini.
Ingxubevange emhlophe (Babbitt) : Ingaphezulu lethayela lenduku yokuxhuma, ikakhulukazi indawo engaphakathi, ngokuvamile yenziwa ngengxubevange emhlophe (ingxubevange ye-polymetallic equkethe ithini nomthofu). Ingxubevange emhlophe, eyaziwa nangokuthi i-babbitt alloy, umsebenzi wayo oyinhloko uthambile, uthambisa futhi awugugi, osiza ekunciphiseni ukuthintana okuqondile phakathi kwezinsimbi nokunciphisa ukuguga.
Kafushane, ukukhethwa kwezinto ezibonakalayo zezintambo zokuxhuma kuklanyelwe ukuhlinzeka ngokumelana okuhle kokugqoka, ukumelana nokushisa okuphezulu kanye nokusebenza kokuzivumelanisa nemvelo yokusebenza eyinkimbinkimbi yenjini.
