Iyini i-crankshaft? Yenzani i-crankshaft? Ukwakheka kwe-crankshaft?
I-crankshaft ingenye yezingxenye ezibaluleke kakhulu zenjini, ithatha amandla enduku yokuxhumanisa bese iyiguqula ibe yi-torque output nge-crankshaft bese iqhuba ezinye izesekeli enjinini ukuthi zisebenze. I-crankshaft ithintwa amandla e-centrifugal obunzima obujikelezayo, amandla e-periodic gas inertia kanye namandla e-reciprocating inertia, okwenza i-crankshaft ithwale isenzo sokugoba kanye nomthwalo wokugoba. Ngakho-ke, i-crankshaft iyadingeka ukuthi ibe namandla nokuqina okwanele, futhi ubuso bejenali budinga ukumelana nokuguguleka, bufane futhi bulinganisele. I-crankshaft yenziwe ngensimbi yesakhiwo sekhabhoni noma i-ductile iron, futhi ngemva kokufakwa kwenduku yokuxhumanisa, ingathwala ukunyakaza okuphezulu nokuphansi (reciprocating) kwenduku yokuxhumanisa, futhi iyiguqule ibe ukunyakaza okujikelezayo (retating). Umsebenzi oyinhloko we-crankshaft ukuguqula ukunyakaza okuphezulu nokuphansi okuphindaphindayo kwenjini kube ukunyakaza okujikelezayo, ngaleyo ndlela inikeze amandla ohlelweni lonke lwemishini.
Indima ye-crankshaft ihlanganisa ikakhulukazi amaphuzu alandelayo:
Amandla okudlulisa: I-crankshaft idlulisela amandla e-piston ku-output shaft ngokuguqula ukunyakaza okuqondile okubuyelanayo kwe-piston kube ukunyakaza okujikelezayo okujikelezayo, futhi iqhube ezinye izingxenye zenjini ukuthi zisebenze, njengama-valve, ama-piston, izinduku zokuxhuma, njll.
Dlulisa i-torque kanye nesivinini: I-crankshaft ingadlulisela i-torque kanye nesivinini senjini ku-output shaft, ukuze imoto ikwazi ukukhiqiza amandla ngenkathi ishayela, ukuze injini isebenze kahle.
Ukumelana ne-torque: I-crankshaft idinga futhi ukumelana ne-torque kanye namandla angaphakathi enjini ukuqinisekisa ukusebenza okuvamile kwenjini.
I-valve yokulawula: I-crankshaft ilawula umoya wokungenisa kanye nokukhipha umoya esilinda ngokulawula ukuvulwa nokuvalwa kwe-valve ukuqinisekisa ukusebenza okuvamile kwenjini.
Ngokuvamile, i-crankshaft ingenye yezingxenye ezibaluleke kakhulu zenjini, indima yayo ukuguqula ukunyakaza okuqondile okuhambisanayo kwe-piston kube ukujikeleza okujikelezayo kwe-crankshaft ukuze kuqhutshwe ezinye izingxenye zenjini ukuthi zisebenze, kodwa futhi kudingeka imelane namandla ahlukahlukene kanye nezikhathi ukuqinisekisa ukusebenza okuvamile kwenjini.
I-crankshaft ikakhulukazi yakhiwe yizingxenye ezilandelayo:
Intamo yesipindo: Ingxenye eyinhloko esekelayo ye-crankshaft, esekelwa yi-bearing eyinhloko endlini yokuthwala eyinhloko ye-crankcase. I-axis yentamo yesipindo yonke isemgqeni ofanayo oqondile.
Ijenali yenduku yokuxhuma (iphinikhodi ye-crank): ukuphambuka kusuka ku-axis yejenali yeshaft eyinhloko ukuze kufakwe ijenali yenduku yokuxhuma, futhi kukhona i-Angle ethile phakathi kwejenali yenduku yokuxhuma ukuguqula amandla avela endukwini yokuxhuma abe yi-torque ejikelezayo ye-crankshaft.
I-Crank (ingalo ye-crank): Ingxenye exhumanisa ijenali yenduku yokuxhuma kanye nejenali ye-shaft eyinhloko ndawonye ukuguqula amandla avela endukwini yokuxhuma abe yi-torque ejikelezayo ye-crankshaft.
Isisindo esiphikisayo: isetshenziselwa ukulinganisela i-torque ye-centrifugal engalingani yenjini, futhi ngezinye izikhathi ukulinganisela ingxenye yamandla e-inertia aphindaphindayo ukwenza i-crankshaft ijikeleze kahle.
Umgodi ongaphambili (ingxenye ekhululekile): osetshenziselwa ukufaka i-pulley yepompo yamanzi, i-pulley yesikhathi se-crankshaft, njll.
I-flange yangemuva: isetshenziselwa ukufaka i-flywheel, i-journal yangemuva kanye ne-flange ye-flywheel phakathi kwe-flange yamafutha kanye nentambo yokubuyisa, ukuvimbela uwoyela ukuthi ungaphumi emuva.
Umgomo wokusebenza we-crankshaft uhilela ukuguqula amandla avela endukwini yokuxhuma abe yi-torque, ekhishwa nge-crankshaft futhi iqhube ezinye izesekeli enjinini ukuthi zisebenze. Kule nqubo, i-crankshaft ithintwa amandla e-centrifugal esisindo esijikelezayo, amandla e-inertia yegesi okushintsha ngezikhathi ezithile kanye namandla e-inertia aphindaphindayo, futhi ithwala isenzo sokugoba kanye nomthwalo wokugoba. Ngakho-ke, i-crankshaft idinga ukuba namandla nokuqina okwanele, futhi ubuso bejenali budinga ukumelana nokuguguleka, bufane futhi bulingane.
Sicela usishayele ucingo uma udinga imikhiqizo enjalo.
I-Zhuo Meng Shanghai Auto Co., Ltd. izibophezele ekuthengiseni izingxenye zezimoto ze-MG&MAUXS futhi wamukelekile ukuzithenga.
