1. Isisindo senduku yokuxhuma ipiston sinethonya elithile emehlukweni webanga lengalo, ikakhulukazi ezinjinini ezinkulu zedizili ezinesivinini esiphansi.
Umthetho wethonya lesisindo senduku yokuxhuma i-piston kumehluko webanga lengalo ngokuvamile: lapho isisindo se-shaft ngayinye eyinhloko sifana nomfaniswano kanye nephephabhuku eliyinhloko kanye nehlathi eliphansi elithwalayo linamathele kahle, susa induku yokuxhuma i-piston. Uma umehluko webanga lengalo yasekuqaleni uphozithivu , Inani eliphozithivu liyehla futhi lisondele kuziro noma inani eliyinegethivu, ukuze i-axis ye-crankshaft ijwayele ukugoba esiqondisweni sokunikezwayo esikhuphukayo. Ezinjinini zikadizili ezincane neziphakathi nendawo, ngenxa yesisindo esilula senduku yokuxhuma ipiston kanye nokuqina okuphezulu kwe-crankshaft, alikho ithonya elisobala ebangeni lengalo ye-crankshaft ngaphambi nangemva kokususwa kwenduku yokuxhuma ipiston, ngokuvamile engadluli. 0.03mm.
2. Umthelela wezimo zokulayisha umkhumbi kumehluko webanga lengalo ye-crankshaft.
Lokhu kungenxa yokusabalalisa okungalingani kwe-buoyancy kanye nesisindo sokulayisha ku-hull, okuyenza igobe ngokunwebeka futhi ikhubazekile, okuthinta ukuguqulwa kwesisekelo somshini futhi iguqule umehluko webanga lengalo ye-crankshaft. Egumbini lenjini ye-midship, lapho umthwalo ugxile engxenyeni engemuva nangemuva komkhumbi, kuzokwenza ukuthi i-hull igobele phezulu, okubangela ukuthi i-axis ye-crankshaft nayo igobele phezulu. Njengoba ukufakwa nokulungiswa kwe-crankshaft kuvame ukwenziwa lapho umkhumbi ungenalutho, ukunakwa okuphelele kufanele kukhokhwe esimweni sokulayisha. Lapho ubeka isisekelo, kuhle kakhulu ukwenza umehluko webanga lengalo ye-crankshaft ube positive (ngisho noma i-eksisi i-concave). Ngale ndlela, lapho umkhumbi ulayishwe kakhulu, isikebhe sizoba nesimo se-convex, ukuze i-axis ye-crankshaft icishe iqonde. Le ndlela ayifanele kuphela igumbi lenjini ye-midship, kodwa futhi negumbi lenjini elingemuva. Ngaphezu kwalokho, nakuba i-ballast yomkhumbi, amanzi ahlanzekile namafutha kunomthelela ofanayo kumehluko webanga lengalo njengokulayisha, ngoba umthelela awumkhulu, uvame ukunganakwa futhi awubalwa.
3. Umthelela wokuguga okungalingani kwe-abheri eyinhloko emehlukweni webanga lengalo ye-crankshaft.
Uma ibhereyidi eyodwa noma amaningi egugile, ijenali eyinhloko izocwila ngokungalingani, okuzoshintsha umehluko webanga lengalo ye-crankshaft. Ukuguga okungalingani kwe-bearing eyinhloko kubangelwa ikakhulukazi ukungalingani kwamasilinda asetshenziswayo, ukungahlangani kahle kwe-bearing eyinhloko, ukwehluleka kwesistimu yokugcoba, izinga elibi lamafutha okugcoba, noma izinga elibi le-wear- i-alloy resistant of individual bearings.
4. Umthelela wesimo sokupholisa senjini kadizili esikhaleni sengalo ye-crankshaft.
Isimo esibandayo senjini kadizili sisho isimo lapho izinga lokushisa layo lilingana nezinga lokushisa lendawo, kanti izinga lokushisa lisho izinga lokushisa lenjini kadizili ngemuva kwesikhathi sokusebenza. Ngaphansi kwezimo ezifanayo zezinye izimo, umehluko webanga lengalo elilinganiselwe phakathi kwesimo esibandayo kanye nesimo esishisayo senjini kadizili wehlukile. Umthetho ojwayelekile uthi: ukulinganisa esimweni esishisayo kuzokwandisa umehluko webanga lengalo ekuqondeni kwevelu engalungile kunesilinganiso esimweni esibandayo. . Uma umehluko wegebe lengalo ungalungile esimweni esibandayo, inani elingalungile liyakhuphuka esimweni esishisayo; uma umehluko wegebe lengalo ulungile esimweni esibandayo, inani eliphozithivu liyehla futhi livame ukuba uziro noma libe negethivu esimweni esishisayo. Esimeni esishisayo, i-axis ye-crankshaft igoba ibheke phezulu.
5. Umthelela wesisindo se-flywheel kumehluko webanga lengalo ye-crankshaft.
Ngemva kokufakwa kwe-flywheel, umehluko webanga lengalo le-crank ngasekugcineni kwe-flywheel uyakhuphuka ngendlela yenani elinegethivu noma wehle ngayo lapho kunevelu ephozithivu khona, futhi i-axis ye-crankshaft ivamise ukugobela phezulu. Umthelela wesisindo se-flywheel uzobandakanya umehluko webanga lengalo le-crank yesibili ukusuka ekugcineni kwe-flywheel. Lokhu kungenxa yokuthi i-arch engenhla ye-crankshaft ikhubazekile futhi ukuthwala kuhlukanisiwe nokuthwala. I-axis yayo iyafana naleyo ye-crank ngasekugcineni kwe-flywheel, kodwa izinga lokuthonya lincane.
6. Umthelela wokucinana kwamabhawodi ekhona elingaphansi noma ngamabholithi kumehluko webanga lengalo ye-crankshaft.
Ngemuva kokuthi injini kadizili isebenze isikhathi esithile, amanye amabhawodi okusetshenzwa kulengwa kanye namabhawodi azoxega. Kuthinta ukusebenza okuvamile kwezinjini zikadizili. Kungenzeka ukuthi isimo sesisekelo somshini sizoshintsha, esizoshintsha umehluko webanga le-crankshaft arm. Uma injini kadizili ilungiswa, ngaphambi kokuhlolwa kwe-crankshaft centerline, qala uhlole ukuthi amabhowuthi okusetshenzwa kwe-anchor axegekile yini, nokuthi amabhlogo womcamelo phakathi kwesihlalo senjini kanye nesisekelo se-hull akhululekile yini. Lapho uhlola, sebenzisa isando esincane ukuze ushaye kancane iphedi. Uma kunomsindo omkhulu lapho uthepha, kusho ukuthi oxhumene naye muhle. Ukuqiniswa kwama-bolts kufanele kwenziwe ngokuhambisana nezindlela nezidingo ezichazwe encwadini yeziqondiso. Izinhlangothi ezingakwesokunxele nezingakwesokudla kufanele ziqiniswe ngesikhathi esifanayo, futhi ama-bolts kufanele aqiniswe kusukela phakathi kuya ezinhlangothini ezimbili izikhathi ezimbili.
Ngemva kokuhlaziya kabanzi izici ezihlukahlukene ezithinta umehluko webanga le-crank arm, kungaphethwa ngokuthi “umehluko webanga le-crank arm uyinani ngaphansi kwezimo ezithile, futhi uyinani elihlobene. Uma izimo zishintsha, inani lomehluko webanga lengalo liphinde libe Ukushintshwa". Ngakho-ke, lapho uhlaziya umehluko webanga lengalo, kufanele uqale uqonde izimo zokulinganisa, bese uziqhathanisa ngaphansi kwezimo ezicishe zifane, ngaphandle kwalokho ngeke kube nenjongo. . Ngemuva kokuthi i-crankshaft ifakwe i-flywheel kanye ne-piston yokuxhuma induku, uma ama-bearings ayinhloko e-coaxial, umehluko webanga le-crank arm ungase ungabi wonke uziro, uma umehluko webanga le-crank uphelele uziro, akusho ukuthi ama-bearings amakhulu Kumelwe abe yi-coaxial Ngokuvamile akunakucatshangwa ukuthi ikhwalithi engcono kakhulu yokuhlanganisa yilapho umehluko webanga le-crank arm ulungiswa ukuze ube uziro.
