Yintoni i-crankshaft? Yenza ntoni i-crankshaft? Ukwakhiwa kwe crankshaft?
I-crankshaft yenye yezona ndawo zibalulekileyo ze-injini, ithatha amandla kwi-rod yokudibanisa kwaye iyiguqule ibe yi-torque output ngokusebenzisa i-crankshaft kwaye iqhube ezinye izincedisi kwi-injini ukuba zisebenze. I-crankshaft ichatshazelwa ngamandla we-centrifugal yobunzima obujikelezayo, amandla e-inertia yegesi ephindaphindiweyo kunye ne-inertia yamandla aphindaphindayo, okwenza ukuba i-crankshaft ithwale isenzo sokugoba kunye nomthwalo ojikelezayo. Ke ngoko, i-crankshaft iyadingeka ukuba ibe namandla okwaneleyo kunye nokuqina, kwaye umphezulu wejenali kufuneka unganxibi, ufane kwaye ulungelelane. I-crankshaft yenziwe nge-carbon structural steel okanye i-ductile iron, kwaye emva kokuba intonga yokudibanisa ifakwe, inokuthwala i-up and down (i-reciprocating) intshukumo yentonga yokudibanisa, kwaye iyiguqule ibe yisetyhula (ejikelezayo). Umsebenzi ophambili we-crankshaft kukuguqula intshukumo ebuyela phezulu nasezantsi ye-injini ibe yintshukumo ejikelezayo, ngaloo ndlela inika amandla kuyo yonke inkqubo yomatshini.
Indima yecrankshaft ikakhulu ibandakanya la manqaku alandelayo:
Amandla okuhambisa: I-crankshaft idlulisela amandla episton kwi-shaft ephumayo ngokuguqula intshukumo ebuyelayo yomgca wepiston ibe yintshukumo ejikelezayo ejikelezayo, kwaye iqhube ezinye iindawo ze-injini ukuba zisebenze, njengeevalve, ipistons, iintonga zokudibanisa, njl. .
I-torque yokudlulisa kunye nesantya: I-crankshaft inokudlulisa i-torque ye-injini kunye nesantya kwi-shaft yokuphuma, ukuze imoto ikwazi ukuvelisa amandla ngelixa iqhuba, ukuze injini isebenze ngokuqhelekileyo.
Ukumelana netorque: I-crankshaft nayo kufuneka imelane netorque kunye namandla angasebenziyo e-injini ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini.
I-valve yokulawula: I-crankshaft ilawula ukungena kunye nokukhupha umoya kwi-cylinder ngokulawula ukuvulwa kunye nokuvala i-valve ukuqinisekisa ukusebenza okuqhelekileyo kwe-injini.
Ngokubanzi, i-crankshaft yenye yezona ndawo zibaluleke kakhulu ze-injini, indima yayo kukuguqula intshukumo ephindaphindayo yepiston ibe kumjikelezo ojikelezayo we-crankshaft ukuqhuba ezinye iindawo ze-injini ukuba zisebenze, kodwa kwakhona kufuneka ukumelana neentlobo ezahlukeneyo zemikhosi kunye namaxesha okuqinisekisa ukusebenza okuqhelekileyo kwe-injini.
I-crankshaft ikakhulu iqulathe la malungu alandelayo:
Intamo esontayo: Elona candelo lixhasayo lecrankshaft, lixhaswe ngowona mthombo wezindlu ze crankcase. I-axis yentamo yokusonta yonke ikumgca othe ngqo ofanayo.
Ijenali yentonga yokudibanisa (i-crank pin) : iyaphambuka kwi-axis yejenali ye-shaft engundoqo ukufakela ijenali yentonga yokudibanisa, kwaye kukho i-Angle ethile phakathi kwejenali yentonga yokudibanisa ukuguqula amandla ukusuka kwintonga yokudibanisa ukuya kwi-torque ejikelezayo ye-crankshaft. .
I-Crank (i-crank arm) : Indawo edibanisa ijenali yokudibanisa intonga kunye nejenali ye-shaft engundoqo kunye ukuguqula amandla ukusuka kwintonga yokudibanisa ukuya kwi-torque ejikelezayo ye-crankshaft.
I-Counterweight: isetyenziselwa ukulinganisa i-torque ye-centrifugal engalungelelananga ye-injini, kwaye ngamanye amaxesha ukulinganisa inxalenye yamandla aphindaphindayo e-inetia ukwenza i-crankshaft ijikeleze kakuhle.
Ishafti yangaphambili (isiphelo esikhululekileyo) : isetyenziselwa ukufaka ipuli yempompo yamanzi, i-crankshaft timing pulley, njl.
Ukuphela kweflange ngasemva: esetyenziselwa ukufakela i-flywheel, ijenali yesiphelo esingasemva kunye neflange ye-flywheel phakathi kweflange yeoli kunye nomsonto wokubuya, ukuthintela i-oyile ekuvuzeni ngasemva.
Umgaqo wokusebenza we-crankshaft ubandakanya ukuguqula amandla ukusuka kwintonga yokudibanisa ukuya kwi-torque, ephuma kwi-crankshaft kwaye iqhube ezinye izincedisi kwi-injini ukuba zisebenze. Kule nkqubo, i-crankshaft ichaphazeleka ngamandla e-centrifugal yobunzima obujikelezayo, i-gas inertia force of periodic change kunye ne-reciprocating inertia force, kwaye ithwala isenzo sokugoba kunye nomthwalo we-torsional. Ke ngoko, i-crankshaft kufuneka ibe namandla okwaneleyo kunye nokuqina, kwaye umphezulu wejenali kufuneka unganxibi, ufane kwaye ulungelelane.
