Mugodhi we crank.
Chinhu chinonyanya kukosha muinjini. Inotora simba kubva padanda rekubatanidza rori yorishandura kuita torque inobuda kuburikidza necrankshaft yoita kuti zvimwe zvinhu zviri painjini zvishande. Crankshaft inokanganiswa nesimba recentrifugal remass anotenderera, periodic gas inertia force uye reciprocating inertia force, izvo zvinoita kuti crankshaft ikwanise kukotama uye torsional load. Saka, crankshaft inodiwa kuti ive nesimba rakakwana uye kuomarara, uye nzvimbo yejournal inofanira kunge isingapfeki, yakafanana uye yakaenzana.
Kuti kuderedze huremu hwe crankshaft uye simba re centrifugal rinogadzirwa panguva yekufamba, crankshaft journal inowanzova isina chinhu. Nzvimbo yega yega yejournal ine gomba remafuta rekupinza kana kubvisa mafuta kuti aise pamusoro pejournal. Kuti kuderedze kuwanda kwekushushikana, kubatana kwemutsipa wespindle, crank pin ne crank arm zvakabatana ne transitional arc.
Basa re crankshaft counterweight (inozivikanwawo se counterweight) nderekuenzanisa simba rinotenderera re centrifugal uye nguva yaro, uye dzimwe nguva simba rinodzokororwa re inertial uye nguva yaro. Kana masimba aya nenguva dzacho zvakaenzana, huremu hwe balance hunogonawo kushandiswa kuderedza mutoro pa main bearing. Nhamba, saizi uye nzvimbo ye balance huremu inofanira kutariswa zvichienderana nehuwandu hwema cylinders einjini, kurongeka kwema cylinders uye chimiro che crankshaft. Balance huremu hunowanzo umbwa kana kuumbwa mu crankshaft, uye high-power diesel balance huremu hunogadzirwa hwakasiyana ne crankshaft uye hwobva hwabatanidzwa pamwe chete.
Kunyungudutsa
Kuwana simbi inopisa ine sarufa shoma uye inopisa ndiyo kiyi yekugadzira simbi yemhando yepamusoro ine ductile. Midziyo yekugadzira yemumba inonyanya kushandiswa pakugadzira cupola, uye simbi inopisa haisi mushonga we desulfurization usati wabviswa; Izvi zvinoteverwa nesimbi yenguruve isina kuchena zvakanyanya uye coke yakanaka. Simbi yakanyungudutswa inonyungudutswa mu cupola, yobviswa sarufa kunze kwechoto, yozodziiswa uye yogadziriswa mu induction furnace. MuChina, kuonekwa kwesimbi yakanyungudutswa kwave kuchiitwa ne vacuum direct reading spectrometer.
kuumba
Maitiro ekuumba mhepo ine simba remhepo ari nani pane maitiro ekuumba jecha revhu, uye anogona kuwana ma crankshaft castings akanyatsogadzirwa. Chiumbwa chejecha chinogadzirwa nemaitiro aya chine hunhu hwekusava ne rebound deformation, izvo zvakakosha zvikuru kune multi-throw crankshaft. Vamwe vagadziri ve crankshaft vemuno vanobva kuGermany, Italy, Spain nedzimwe nyika vanotanga maitiro ekuumba mhepo ine simba remhepo, asi kuunzwa kwemutsara wese wekugadzira inhamba diki chete yevagadziri.
Kukanda kweElectroslag
Tekinoroji yekunyungudutsa electroslag inoshandiswa pakugadzira crankshaft, kuitira kuti mashandiro e crankshaft yakakandwa aenzane neaya e crankshaft yakagadzirwa. Uye ine hunhu hwekukurumidzira kugadzirwa, kushandiswa kwesimbi kwakanyanya, michina iri nyore, mashandiro epamusoro echigadzirwa nezvimwewo.
Tekinoroji yekugadzira
Mutsetse weotomatiki une hot die forging press uye electric hydraulic hammer seyinjini huru ndiyo nzira yekugadzira crankshaft. Mitsetse iyi yekugadzira inowanzo tora matekinoroji epamusoro akadai sekucheka nemazvo, kugadzira roll forging (cross wedge rolling), kupisa kwepakati nepakati, kupedzisa hydraulic press finishing, nezvimwewo. Panguva imwe chete, vane michina yekubatsira yakaita sema manipulators, conveyor belts uye mold change devices inodzoserwa kuturntable kuti igadzire flexible manufacturing system (FMS). FMS inogona kuchinja otomatiki workpiece uye kufa uye kugadzirisa otomatiki parameters, uye kugara ichiyera panguva yekushanda. Ratidza uye nyora data senge forging thickness uye maximum pressure uye kuenzanisa ne fixed values kuti usarudze deformation yakanakisa yezvigadzirwa zvemhando yepamusoro. Sisitimu yese inotariswa ne central control room, zvichiita kuti kushanda kusina munhu. Crankshaft inogadzirwa nenzira iyi yekuumba ine fiber yakazara ye internal metal flow line, iyo inogona kuwedzera simba rekuneta neinopfuura 20%.
Kana uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonerei kana muchida zvigadzirwa zvakadaro.
