Kodi crankshaft m'galimoto ndimotani ndipo imagwira ntchito bwanji

Crankshaft mgalimoto

Crankshaft ndi gawo la injini yamagalimoto yoyendetsedwa ndi gulu la pisitoni. Imasinthitsa makokedwe kupita ku flywheel, yomwe imazungulira magiya opatsira. Kupitilira apo, kusinthaku kumafalikira kumayendedwe oyendetsera magudumu oyendetsa.

Magalimoto onse pansi pa hood omwe amaikidwa injini zoyaka mkati, yokhala ndi makina oterewa. Gawoli limapangidwira mtundu wa injini, osati mtundu wamagalimoto. Pogwira ntchito, crankshaft imadzipukusa motsutsana ndi mawonekedwe amkati oyaka moto momwe adayikiramo. Chifukwa chake, m'malo mwake, ma minders nthawi zonse amayang'anitsitsa kukulira kwa zinthu zopaka ndi chifukwa chake zidawonekera.

Kodi crankshaft imawoneka bwanji, ili kuti ndipo ndizovuta ziti?

Mbiri ya Crankshaft

Monga chinthu chodziyimira chokha, crankshaft sinawonekere usiku wonse. Pachiyambi, teknoloji ya crank idawonekera, yomwe idagwiritsidwa ntchito m'madera osiyanasiyana a ulimi, komanso mafakitale. Mwachitsanzo, ma crank oyendetsedwa ndi manja adagwiritsidwa ntchito kuyambira 202-220 AD. (m’nthawi ya ufumu wa Han).

Chodziwika bwino cha zinthu zotere chinali kusowa kwa ntchito yosinthira mayendedwe obwereza kukhala ozungulira kapena mosemphanitsa. Zogulitsa zosiyanasiyana zopangidwa ndi mawonekedwe a crank zidagwiritsidwa ntchito mu Ufumu wa Roma (zaka za II-VI AD). Mafuko ena apakati ndi kumpoto kwa Spain (Celtiberians) ankagwiritsa ntchito mphero zomangirira, zomwe zinkagwira ntchito pa mfundo ya crank.

M'mayiko osiyanasiyana, luso limeneli lakonzedwa bwino ndi kugwiritsidwa ntchito pa zipangizo zosiyanasiyana. Ambiri a iwo ankagwiritsidwa ntchito potembenuza magudumu. Cha m'zaka za m'ma 15, makampani opanga nsalu anayamba kugwiritsa ntchito ng'oma zomwe zikopa za ulusi zinkawombera.

Koma crank yokhayo sipereka kasinthasintha. Chifukwa chake, ziyenera kuphatikizidwa ndi chinthu china chomwe chingapereke kutembenuka kwamayendedwe obwereza kukhala kasinthasintha. Katswiri wina wachiarabu Al-Jazari (anakhalako kuyambira 1136 mpaka 1206) anapanga crankshaft yathunthu, yomwe, mothandizidwa ndi ndodo zolumikizira, imatha kupanga masinthidwe otero. Anagwiritsa ntchito njira imeneyi m’makina ake pokwezera madzi.

Pamaziko a chipangizochi, njira zosiyanasiyana zinapangidwa pang'onopang'ono. Mwachitsanzo, munthu wina wa m’nthawi ya Leonardo da Vinci, dzina lake Cornelis Corneliszun, anamanga makina ocheka matabwa omwe ankayendetsedwa ndi makina oyendera mphepo. Mmenemo, crankshaft idzachita ntchito yosiyana poyerekeza ndi crankshaft mu injini yoyaka mkati. Mosonkhezeredwa ndi mphepo, mtengowo unkazungulira, womwe, mothandizidwa ndi ndodo zomangira ndi zikwapu, umasintha mayendedwe ozungulira kukhala oyenda mobwerezabwereza ndikusuntha macheka.

Pamene makampani akukula, ma crankshafts adatchuka kwambiri chifukwa cha kusinthasintha kwawo. Injini yothandiza kwambiri mpaka pano idakhazikitsidwa pakusintha kwamayendedwe obwereza kuti ayende mozungulira, zomwe zingatheke chifukwa cha crankshaft.

Kodi crankshaft ndi chiyani?

Monga mukudziwa, m'mainjini oyaka kwambiri amkati (momwe injini zina zoyaka zamkati zimagwirira ntchito, werengani m'nkhani ina) pali njira yosinthira mayendedwe obwereza kukhala mayendedwe ozungulira. Chitsulo champhamvu chimakhala ndi ma pistoni okhala ndi ndodo zolumikizira. Mpweya wosakanikirana ndi mafuta zikalowa mu silinda ndikutenthedwa ndi mphamvu, mphamvu zambiri zimatulutsidwa. Kutulutsa mpweya kumakankhira pisitoniyo pansi pakatikati.

Zitsulo zonse zimakhala pa ndodo zolumikiza, zomwe zimamangiriridwa ku crankshaft yolumikiza magazini. Chifukwa chakuti nthawi yogwiritsira ntchito masilindala onse ndi yosiyana, zotsatira za yunifolomu zimagwiritsidwa ntchito pamakina oyeserera (kuthamanga kwakanthawi kumadalira kuchuluka kwa zonenepa zamagalimoto). Izi zimapangitsa kuti crankshaft izizungulira mosalekeza. Kuyenda kozungulira kumatumizidwa ku flywheel, ndipo kuchokera pamenepo kudzera pa clutch kupita ku gearbox kenako kuma wheel wheel.

Chifukwa chake, crankshaft idapangidwa kuti isinthe mayendedwe amitundu yonse. Gawoli nthawi zonse limapangidwa molondola kwambiri, popeza ukhondo wosinthasintha wa shaft mu gearbox umadalira kuyanjana ndi ndendende yoyeserera kokhotakhota kwa wina ndi mnzake.

Zida zomwe crankshaft imapangidwa

Kupanga ma crankshafts, chitsulo kapena ductile chitsulo chimagwiritsidwa ntchito. Cholinga chake ndikuti gawolo lili ndi katundu wolemera (makokedwe apamwamba). Chifukwa chake, gawo ili liyenera kukhala lamphamvu kwambiri komanso lolimba.

Kupanga zosintha zachitsulo, kuponyera kumagwiritsidwa ntchito, ndikusintha kwazitsulo. Kuti apange mawonekedwe abwino, lathes amagwiritsidwa ntchito, omwe amayang'aniridwa ndi mapulogalamu amagetsi. Chogulitsacho chikayamba kupangika, chimakhala mchenga, kuti chikhale cholimba, chimakonzedwa pogwiritsa ntchito kutentha kwambiri.

Kapangidwe ka crankshaft

Chovalacho chimayikidwa m'munsi mwa injini molunjika pamwamba pa sump yamafuta ndipo chimakhala ndi:

• magazini yayikulu - gawo lothandizira la gawo lomwe limayikidwa chonyamula mota;
