Crankshaft yog ib qho tseem ceeb tshaj plaws ntawm lub cav, nws txoj haujlwm yog ua kom cov pa roj av, kiv cua sib txuas, cov hluav taws xob nce qib, thiab lwm yam.)
Crankshaft flywheel group: 1- pulley; 2- crankshaft timing tooth belt wheel; 3- crankshaft sprocket; 4- Crankshaft; 5- Crankshaft tseem muaj kabmob (saum); 6- Flywheel; 7- Ceev Sensor Teeb Liab Generator; 8, 11- Pawm ncoo; 9- Crankshaft cov kabmob (hauv qab); 10- Crankshaft caps npog npog.
Thaum cov crankshaft ua haujlwm, nws yuav tsum tiv thaiv cov kev hloov pauv ntawm cov kev hloov pauv, ntxiv rau lawv lub zog kom txaus, thiab tawv ncauj, kev coj nyab, kev coj ua zoo thiab kev sib npaug zoo. Lub crankshaft feem ntau yog ua los ntawm nruab nrab carbon alloy steel, thiab cov neeg sau xov xwm chaw tau kho los ntawm kev ua haujlwm siab quenching lossis nitregencal. Shanghai Santana Cav Crankshaft yog ua los ntawm cov roj carbon me nruab nrab hauv nruab nrab. Lub Audi JW thiab Yuchai YC6105QC tshuab yog ua los ntawm cov nqi qis, high-lub zog tsis tshua muaj cov hlau nrog cov coj zoo hnav tsis kam.
Lub crankshaft yog feem ntau muaj nyob ntawm sab xub ntiag, lub caj qaum tseem ceeb, ib qho Crank, ib qho kev sib ntaus sib tua, kev sib txuas sib txuas cov ntawv sau ua Rod phau ntawv xov xwm thiab lub nraub qaum. Ib tug crank yog tsim los ntawm kev sib txuas cov nkauj sau nkauj sib txuas thiab nws sab laug thiab txoj cai nco txog. Tus naj npawb ntawm crank ntawm crankshaft nyob ntawm tus naj npawb thiab kev npaj ntawm cov kheej kheej kheej kheej. Lub crankshaft ntawm ib lub tshuab raj kheej tsuas muaj ib qho crank xwb; Tus naj npawb ntawm crank ntawm crankshaft ntawm ib lub cav hauv-line yog sib npaug nrog cov nab hau; Tus naj npawb ntawm cranks hauv crankshaft ntawm lub v cav yog sib npaug li ib nrab ntawm cov cooj ntawm cov thooj voos kheej kheej. Cov ncej pem hauv ntej-kawg ntawm lub crankshaft yog nruab nrog lub pulley, lub sijhawm iav, thiab lwm yam, uas yog siv los tsav lub twj tso dej thiab cov khoom siv valve. Lub spindle caj dab ntawm crankshaft yog ntsia hauv lub ntsiab cov kabmob tseem ceeb ntawm lub tog raj kheej thiab yog siv los txhawb cov crankshaft. Cov phau ntawv sau cov ntawv sau sib txuas yog siv los nruab cov pas nrig sib txuas, thiab cov crank txuas lub ntsiab qauv phau ntawv xov xwm sib txuas nrog kev sib txuas sib txuas cov ntawv xov xwm. Txhawm rau sib npaug ntawm cov quab yuam centrifugal thaum cov crankshaft rotates, ib qho kev sib npaug thaiv yog muab rau crankshaft. A connecting flange is provided at the rear end of the crankshaft to connect the flywheel to the crankshaft by bolts. To lubricate the connecting rod journal, a lubricating passage is drilled from the main shaft journal to the connecting rod journal. Cov crankshaft tseem ceeb yog qhov yooj yim hauv kev teeb meem, lub teeb nyob rau hauv kev ua haujlwm, thiab feem ntau tau siv cov pob tshab, uas tau siv dav hauv nruab nrab thiab tshuab me me.
Cov duab ntawm crankshaft thiab txoj kev txheeb ze ntawm txhua tus crank tsuas yog nyob ntawm tus naj npawb ntawm cov thooj voos kheej kheej thiab kev npaj ua haujlwm ntawm txhua lub tog raj kheej. When arranging the engine work sequence, the following rules should be followed as far as possible:
Ua rau ob lub voos kheej kheej ntawm kev ua haujlwm txuas ntxiv raws li qhov ua tau kom txo tau cov kabmob ntawm ob lub sijhawm "Huab Cua Loos" cuam tshuam rau kev txhawb nqa lub cav.
Cov kev npaj ntawm crankshaft thiab crank ntawm nyob rau hauv-kab plaub-stroke cav. Kev ua haujlwm ntu ntawm cov hauv-kab plaub-stroke plaub-stroke lub cav yog 720 = 180 °, lossis lub cav hluav taws xob ua ntu zus) yog 1-3-4-4-4-3. Cov khoom ua haujlwm ntawm lub voj voog ua haujlwm feem ntau siv tau muaj ib sab-ob sab sib zog thawb cov ntaub nrog flanging thiab round tshuab raj muaj peb daim ntawv. Lub tshuab qhwv ntaub qhwv yog ib daim ntawv sib tshooj nrog kev sib txhuam cov txheej txheem sab nraud, uas tau teeb tsa hauv qhov zawj ntawm lub cev lossis cov kabmob tseem ceeb. Txhawm rau tiv thaiv kev sib hloov ntawm cov ntaub qhwv qhwv, lub tshuab thawb qhwv tau muaj kev thab plaub hauv qhov zawj. Qee cov ntaub qhwv ntsej muag siv 4 daim ua kom muaj ob qhov kev txwv zoo sib xws, thiab qee qhov siv 2 daim ntawm kev txwv. Sab nrog anti-strong hlau yuav tsum ntsib rau crankshaft.
