Chii chinonzi crankshaft? Chii chinoitwa necrankshaft? Muumbirwo wecrankshaft?
Crankshaft ndeimwe yezvikamu zvakakosha zveinjini, inotora simba kubva patsvimbo yekubatanidza yoishandura kuita torque inobuda kuburikidza necrankshaft uye inofambisa zvimwe zvishandiso painjini kuti zvishande. Crankshaft inokanganiswa nesimba re centrifugal re rotating mass, periodic gas inertia force uye reciprocating inertia force, izvo zvinoita kuti crankshaft ikwanise kukotama uye torsional load. Nokudaro, crankshaft inodiwa kuti ive nesimba rakakwana uye kuomarara, uye nzvimbo yejournal inofanira kuramba yakasakara, yakafanana uye yakaenzana. Crankshaft yakagadzirwa nesimbi ye carbon structural kana ductile iron, uye mushure mekunge connecting rod yaiswa, inogona kutakura kumusoro nekudzika (reciprocating) kufamba kwe connecting rod, uye kuishandura kuita denderedzwa (kutenderera). Basa guru re crankshaft nderekushandura kumusoro nekudzika kwe turnoff yeinjini kuita rotary motion, nokudaro ichipa simba kune system yese ye mechanical.
Basa re crankshaft rinosanganisira zvinhu zvinotevera:
Simba rekutumira: Crankshaft inoendesa simba repiston ku output shaft nekushandura reciprocating linear motion yepiston kuita denderedzwa rinotenderera, uye inofambisa zvimwe zvikamu zveinjini kuti zvishande, zvakaita semavharuvhu, mapiston, connecting rods, nezvimwewo.
Kufambisa torque nekumhanya: Crankshaft inogona zvakare kuendesa torque nekumhanya kweinjini kuenda ku output shaft, kuitira kuti mota igone kugadzira simba panguva yekutyaira, kuitira kuti injini igone kushanda zvakanaka.
Kutsungirira torque: Crankshaft inofanirawo kutsungirira torque uye inertial force yeinjini kuti ive nechokwadi chekuti injini inoshanda zvakanaka.
Vharuvhu yekudzora: Crankshaft inodzora mhepo inopinda uye inoburitsa mweya mu cylinder nekudzora kuvhurwa nekuvharwa kwevharuvhu kuitira kuti injini ishande zvakanaka.
Kazhinji, crankshaft ndeimwe yezvikamu zvakakosha zveinjini, basa rayo nderekushandura kufamba kwepiston kunodzokororwa kuita kutenderera kwecrankshaft kuti ifambise zvimwe zvikamu zveinjini kuti zvishande, asiwo inoda kutsungirira masimba akasiyana-siyana nenguva kuti ive nechokwadi chekuti injini inofamba zvakanaka.
Crankshaft inonyanya kuve nezvikamu zvinotevera:
Mutsipa wespindle: Chikamu chikuru chinotsigira crankshaft, chinotsigirwa nebearing huru iri mubearing housing yecrankcase. Axle yespindle neck yese iri mumutsetse wakatwasuka.
Chinyorwa chetsvimbo yekubatanidza (crank pin): kubva pa axis yebhuku guru reshaft kuti uise bhuku retsvimbo yekubatanidza, uye pane imwe Angle pakati pebhuku retsvimbo yekubatanidza kuti simba ribve patsvimbo yekubatanidza riende ku torque inotenderera ye crankshaft.
Crank (ruoko rwecrank): Chikamu chinobatanidza journal yetsvimbo inobatanidza nejournal yeshaft huru pamwe chete kuti simba rinobva patsvimbo inobatanidza rive torque inotenderera yecrankshaft.
Kurema kwakaenzana: kunoshandiswa kudzikamisa torque yeinjini isina kuenzana, uye dzimwe nguva kudzikamisa chikamu chesimba reinertia rinodzokororwa kuita kuti crankshaft itenderere zvakanaka.
Mugodhi wepamberi (wakasununguka): unoshandiswa kuisa pulley yepombi yemvura, pulley yenguva yecrankshaft, nezvimwewo.
Flange yekumashure: inoshandiswa kuisa flywheel, rear end journal uye flywheel flange iri pakati peflange yemafuta ne thread yekudzosa, kudzivirira mafuta kuti asadonhedze.
Pfungwa yekushanda kwecrankshaft inosanganisira kushandura simba kubva patsvimbo inobatanidza kuita torque, iyo inoburitswa kuburikidza necrankshaft uye inosundira zvimwe zvinhu painjini kuti zvishande. Mukuita uku, crankshaft inokanganiswa nesimba recentrifugal remass anotenderera, simba regesi rekuchinja kweperiodic uye simba rekudzoka kweinertia, uye ine basa rekukotama uye mutoro wekutenderera. Nokudaro, crankshaft inofanira kuva nesimba rakakwana uye kuomarara, uye pamusoro pejournal inofanira kunge isingagoni kupfeka, yakafanana uye yakaenzana.
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
