Crank shaft.
Chinhu chinonyanya kukosha cheinjini. Zvinotora simba kubva padanda rekubatanidza uye rinoshandura 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 inofanirwa kusapfeka, yunifomu uye yakaenzana.
Kuti uderedze huwandu hwe crankshaft uye centrifugal simba rinogadzirwa panguva yekufamba, crankshaft jenari inowanzo gara isina. Imwe neimwe yejenari yepamusoro inopihwa negomba remafuta ekusuma kana kudhirowa mafuta ekuzora pamusoro wejenari. Kuti uderedze kushushikana kwekushushikana, kubatana kweiyo spindle neck, iyo crank pin uye ruoko rwe crank zvakabatanidzwa neinochinja arc.
Basa re crankshaft counterweight (inozivikanwawo se counterweight) ndere kuenzanisa iyo inotenderera centrifugal simba uye nguva yaro, uye dzimwe nguva iyo inodzokorodza inertial simba uye nguva yaro. Kana aya masimba uye nguva pachazvo zvakaenzana, huremu huremu hunogonawo kushandiswa kudzikisa mutoro pakutakura kukuru. Huwandu, saizi uye kuiswa kwechiyero kuyerwa kunofanirwa kutariswa zvichienderana nenhamba yemasilinda ejini, kurongeka kwemasilinda uye chimiro che crankshaft. Huremu huremu hunowanzo kukandwa kana kuumbwa mune imwe ne crankshaft, uye iyo yepamusoro-simba dizeli chiyero chechiyero chinogadzirwa zvakasiyana kubva ku crankshaft uye yobva yabatanidzwa pamwechete.
Kunyunguduka
Kuwana tembiricha yepamusoro uye yakaderera sarufa yakachena inopisa simbi ndiyo kiyi yekugadzira yepamusoro ductile iron. Midziyo yekugadzira yemumba inonyanya kuenderana nekapu, uye simbi inopisa haisi pre-desulfurization kurapwa; Izvi zvinoteverwa nekuchena kwakanyanya kwenguruve iron uye hurombo hwecoke quality. Simbi yakanyungudutswa yakanyungudutswa mucupola, yakanyungudutswa kunze kwechoto, yobva yapiswa uye inogadziriswa muchoto chekupinza. MuChina, kucherechedzwa kwesimbi yakanyungudutswa kuumbwa kwave kuchiitwa nevacuum yakananga kuverenga spectrometer.
kuumba
Iyo mhepo inokanganisa kuumba maitiro zviri pachena kuti yakakwirira kune yevhu jecha kuumba maitiro, uye inogona kuwana yakakwirira-chaiyo crankshaft castings. Iyo jecha mold inogadzirwa neiyi maitiro ine hunhu hwekusina rebound deformation, iyo inonyanya kukosha kune yakawanda-kukanda crankshaft. Vamwe vanogadzira crankshaft mudzimba kubva kuGermany, Italy, Spain nedzimwe nyika kuti vaunze maitiro ekuumba mhepo, asi kuunzwa kwemutsetse wese wekugadzira ingori nhamba diki yevagadziri.
Electroslag casting
Electroslag remelting tekinoroji inoshandiswa pakugadzirwa kwe crankshaft, kuitira kuti kuita kwe cast crankshaft kufanane neye forged crankshaft. Uye ine hunhu hwekukurumidza kusimudzira kutenderera, yakakwira simbi yekushandisa rate, yakapusa michina, yepamusoro chigadzirwa kuita uye zvichingodaro.
Kugadzira tekinoroji
Iyo otomatiki mutsetse ine inopisa die forging press uye yemagetsi hydraulic nyundo sezvo injini huru ndiyo nzira yekusimudzira yekugadzira crankshaft kugadzirwa. Iyi mitsetse yekugadzira inowanzotora matekinoroji epamberi sekucheka kwakaringana, roll forging (cross wedge rolling) kugadzira, yepakati frequency induction heat, kupedzisa hydraulic press finishing, etc. mabhandi uye mold shanduko michina yakadzoserwa kune turntable kuti iite inoshanduka yekugadzira system (FMS). Iyo FMS inogona otomatiki kushandura workpiece uye kufa uye otomatiki kugadzirisa ma paramita, uye inogara ichiyera panguva yekushanda. Ratidza uye rekodha data senge kuforoma ukobvu uye yakanyanya kudzvanywa uye enzanisa neyakagadzika kukosha kusarudza yakanakisa deformation yemhando zvigadzirwa. Iyo yose sisitimu inotariswa nekamuri yepakati yekudzora, ichigonesa kushanda kusingaitwe. Iyo crankshaft inogadzirwa neiyi nzira yekugadzira ine yakazara fiber yemukati simbi inoyerera mutsara, iyo inogona kuwedzera kuneta simba nekupfuura 20%.
Kana iwe uchida kuziva zvakawanda, ramba uchiverenga zvimwe zvinyorwa pane ino saiti!
Ndapota tifonere kana uchida zvigadzirwa zvakadaro.
