Chii chinonzi crankshaft? Ko crankshaft inoita sei? Kuumbwa kwe crankshaft?
Iyo crankshaft ndeimwe yeakakosha zvikamu zveinjini, inotora simba kubva padanda rekubatanidza uye inoshandura kuita torque kubuda kuburikidza ne crankshaft uye inotyaira zvimwe zvishongedzo painjini kuti ishande. Iyo crankshaft inobatwa ne centrifugal simba rekutenderera misa, periodic gasi inertia simba uye inodzokorodza inertia simba, izvo zvinoita kuti crankshaft itakure chiito chekukotama uye torsional mutoro. Naizvozvo, crankshaft inodiwa kuti ive nesimba rakakwana uye kuomarara, uye iyo jenari yepamusoro inoda kusapfeka, yunifomu uye yakaenzana. Iyo crankshaft inogadzirwa nekabhoni structural simbi kana ductile iron, uye mushure mekunge tsvimbo yekubatanidza yaiswa, inogona kutakura kukwira nekudzika (kudzoreredza) kufamba kwetambo yekubatanidza, uye kuishandura kuita denderedzwa (inotenderera) kufamba. Basa guru re crankshaft ndere kushandura kukwira nekudzika kudzokororwa kweinjini kuita kutenderera, zvichipa simba kune yese mechanika system.
Basa re crankshaft rinonyanya kusanganisira zvinotevera pfungwa:
Simba rekufambisa: Iyo crankshaft inotamisa simba repiston kune inobuda shaft nekushandura inodzokorodza mutsara kufamba kwepiston kuita denderedzwa inotenderera, uye inotyaira zvimwe zvikamu zveinjini kuti zvishande, senge mavharuvhu, piston, tsvimbo dzekubatanidza, nezvimwe. .
Transfer torque uye kumhanya: Iyo crankshaft inogona zvakare kuendesa torque yeinjini uye kumhanya kune inobuda shaft, kuitira kuti mota igadzire simba ichityaira, kuti injini ishande zvakajairika.
Kumira torque: Iyo crankshaft inodawo kumira torque uye inertial simba reinjini kuti ive nechokwadi chekushanda kwakajairika kweinjini.
Kudzora valve: Iyo crankshaft inodzora kupinza uye kupera kwemhepo mucylinder nekudzora kuvhura uye kuvhara kwevhavha kuti ive nechokwadi chekushanda kweinjini.
Kazhinji, crankshaft ndechimwe chezvikamu zvakakosha zveinjini, basa rayo ndere kushandura mutsara wepiston kutenderera kutenderera kutenderera kwe crankshaft kutyaira zvimwe zvikamu zveinjini kuti zvishande, asi zvakare zvinoda kumirisana nemhando dzakasiyana dzemasimba uye nguva kuti ive nechokwadi chekushanda kwakajairika kweinjini.
Iyo crankshaft inonyanya kuve nezvikamu zvinotevera:
Spindle neck: Iyo huru inotsigira chikamu che crankshaft, inotsigirwa neiyo huru inotakura muhombe inotakura imba ye crankcase. Axis yehuro yekuruka yese iri mumutsara wakatwasuka wakafanana.
Kubatanidza rod jenari (crank pin) : kutsauka kubva paaxis ye main shaft jenari kuisa iyo yekubatanidza tsvimbo jenari, uye pane imwe Angle pakati peiyo yekubatanidza tsvimbo jenari kushandura simba kubva kudanda rekubatanidza kuita torque inotenderera ye crankshaft. .
Crank (crank arm) : Chikamu chinobatanidza rod rod jenari uye main shaft jenari pamwechete kushandura simba kubva padanda rekubatanidza kuita torque inotenderera ye crankshaft.
Counterweight: inoshandiswa kudzikamisa iyo isina kuenzana centrifugal torque yeinjini, uye dzimwe nguva kudzikamisa chikamu chesimba rinodzokororwa inertia kuita kuti crankshaft itenderere zvakanaka.
Front-end shaft (yemahara magumo): inoshandiswa kuisa pombi yemvura pulley, crankshaft timing pulley, nezvimwe.
Rear end flange: inoshandiswa kuisa flywheel, rear end journal uye flywheel flange pakati pemafuta flange neshinda yekudzokera, kudzivirira mafuta kubva pakudonha.
Nheyo yekushanda ye crankshaft inosanganisira kushandura simba kubva padanda rekubatanidza kuita torque, iyo inobuda kuburikidza ne crankshaft uye inotyaira zvimwe zvinhu painjini kuti ishande. Mukuita uku, crankshaft inobatwa neiyo centrifugal simba rehuremu hunotenderera, iyo gasi inertia simba re periodic shanduko uye inodzosera inertia simba, uye inotakura chiito chekukotama uye torsional mutoro. Naizvozvo, crankshaft inoda kuve nesimba rakakwana uye kuomarara, uye iyo jenari yepamusoro inoda kusapfeka, yunifomu uye yakaenzana.
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
