Menene crankshaft? Menene crankshaft yake yi? A abun da ke ciki na crankshaft?
Crankshaft yana daya daga cikin mahimman sassa na injin, yana ɗaukar ƙarfi daga sandar haɗawa kuma ya canza shi zuwa fitarwa mai ƙarfi ta hanyar crankshaft kuma yana motsa wasu kayan haɗi akan injin don aiki. Ƙarfin crankshaft yana shafar ƙarfin centrifugal na taro mai juyawa, ƙarfin iskar gas na lokaci-lokaci da ƙarfin inertia mai jujjuyawa, wanda ke sa crankshaft ya ɗauki aikin lanƙwasa da nauyin torsional. Sabili da haka, ana buƙatar crankshaft don samun isasshen ƙarfi da ƙima, kuma farfajiyar jarida tana buƙatar zama mai jurewa, uniform da daidaitawa. An yi crankshaft da ƙarfe na tsarin carbon ko ductile iron, kuma bayan an shigar da sandar haɗin, zai iya ɗaukar motsi sama da ƙasa (maimaitawa) na haɗin haɗin, kuma ya juya shi zuwa motsi (juyawa). Babban aikin crankshaft shine canza motsin motsi sama da ƙasa zuwa motsi na jujjuyawa, don haka samar da ƙarfi ga tsarin injin gabaɗaya.
Matsayin crankshaft ya ƙunshi abubuwa masu zuwa:
Ikon watsawa: crankshaft yana canza ƙarfin fistan zuwa mashin fitarwa ta hanyar jujjuya motsi na madaidaiciyar motsi na piston zuwa motsi na madauwari, kuma yana motsa sauran sassan injin don aiki, kamar bawuloli, pistons, sanduna masu haɗawa, da sauransu. .
Canja wurin jujjuyawar motsi da saurin gudu: Har ila yau, crankshaft na iya canja wurin jujjuyawar injin da sauri zuwa mashigin fitarwa, ta yadda motar za ta iya samar da wuta yayin tuki, ta yadda injin zai iya aiki yadda ya kamata.
Jurewa jujjuyawar wuta: Har ila yau, crankshaft yana buƙatar jure juriya da ƙarfin inertial na injin don tabbatar da aiki na yau da kullun na injin.
Bawul ɗin sarrafawa: Ƙaƙwalwar ƙwanƙwasa tana sarrafa ci da shayewar iska a cikin silinda ta hanyar sarrafa budewa da rufewa na bawul don tabbatar da aikin injiniya na yau da kullum.
Gabaɗaya, crankshaft yana ɗaya daga cikin mahimman sassa na injin, aikinsa shine canza motsi na madaidaiciyar motsi na fistan zuwa madauwari na crankshaft don fitar da sauran sassan injin don yin aiki, amma kuma yana buƙatar yin aiki. jure nau'ikan ƙarfi da lokuta don tabbatar da aikin injin na yau da kullun.
crankshaft galibi ya ƙunshi sassa masu zuwa:
Spindle wuya: Babban ɓangaren tallafi na crankshaft, yana goyan bayan babban ɗamarar a cikin babban ɗaki na crankcase. Axis na wuyan sandal duk yana cikin layi madaidaiciya.
Jarida mai haɗawa (crank fil): karkata daga madaidaicin babban mujallar shaft don shigar da jarida mai haɗawa, kuma akwai takamaiman kusurwa tsakanin jaridar sanda mai haɗawa don canza ƙarfin daga sandar haɗin zuwa cikin jujjuyawar jujjuyawar crankshaft. .
Crank (hannun hannu): Bangaren da ke haɗa jaridar sanda mai haɗawa da babban jaridar shaft tare don juyar da ƙarfi daga sandar haɗi zuwa jujjuyawar juzu'i na crankshaft.
Ma'auni mai ƙima: ana amfani da shi don daidaita karfin jujjuyawar ingin mara daidaituwa, wani lokacin kuma don daidaita wani ɓangaren ƙarfin inertia mai jujjuyawar don sanya crankshaft ɗin ya juya sumul.
Shaft na gaba-gaba (ƙarshen kyauta): ana amfani da shi don shigar da injin famfo na ruwa, juzu'i na crankshaft, da sauransu.
Rear karshen flange: yi amfani da shigar da flywheel, na baya karshen jarida da kuma flywheel flange tsakanin mai flange da dawowar zaren, don hana mai daga yoyo baya.
Ka'idar aiki na crankshaft ya haɗa da canza ƙarfin daga sandar haɗawa zuwa juzu'i, wanda ke fitowa ta hanyar crankshaft kuma yana motsa wasu kayan haɗi akan injin don aiki. A cikin wannan tsari, crankshaft yana shafar ƙarfin centrifugal na taro mai juyayi, ƙarfin iskar gas na canji na lokaci-lokaci da kuma ƙarfin inertia mai maimaitawa, kuma yana ɗaukar aikin lanƙwasa da nauyin torsional. Sabili da haka, crankshaft yana buƙatar samun isasshen ƙarfi da ƙarfi, kuma farfajiyar jarida tana buƙatar zama mai jurewa, ɗaki da daidaitawa.
Da fatan za a kira mu idan kuna buƙatar irin waɗannan samfuran.
