Yiziphi izinzuzo zokubumba ama-piston rods?

Izinduku ze-piston ezakhiwe zidume ngamandla azo aphezulu nokuthembeka, okuwenza abe yinketho ekhethwayo ezimbonini ezahlukahlukene. Enye yezinzuzo eziyinhloko zama-piston rods ilele esakhiweni esingokwemvelo sokusanhlamvu okuvela enqubweni yokwenza. Ngokungafani nezinti ze-piston ezicijile noma ezenziwe ngomshini, ezingase zibonise amaphethini okusanhlamvu angajwayelekile kanye ne-voids yangaphakathi, izinti zepiston ezibunjiwe zinesakhiwo sokusanhlamvu esicolisisiwe esilandela i-contour yengxenye. Lokhu kuqondaniswa kwezinhlamvu kuthuthukisa izici zemishini ye-shaft, okuhlanganisa amandla aqinile, ukumelana nokukhathala, nokuqina komthelela. Ngenxa yalokhu, izinti ze-piston ezibunjiwe zibonisa ukuqina okukhethekile futhi zingamelana nezinhlelo zokusebenza ezinengcindezi ephezulu, zizenze zilungele izingxenye ezibalulekile emishinini, amasistimu ezimoto, okokusebenza kwe-aerospace, nokunye.

Ngaphezu kwalokho, inqubo yokubumba ivumela ukulawula okunembile kokuma nobukhulu be-shaft, okuholela ekunembeni okuphakeme kobukhulu nokuqedwa kwendawo. Ngokungafani nokusakazwa, okuvamise ukudinga ukusetshenzwa okubanzi ukuze kuzuzwe isimo esifiselekayo kanye nekhwalithi ephezulu, izinti zepiston ezibunjiwe zingakhiqizwa zibe yisimo esiseduze nenetha, kuncishiswe imfucuza yezinto ezibonakalayo futhi kuncishiswe izindleko zomshini. Ukuwohloka okulawulwayo kwensimbi ngesikhathi sokubumba kuqeda i-voids yangaphakathi kanye ne-porosity evame ukutholakala kuma-cast piston rods, okuholela ku-microstructure eminyene futhi efana ne-homogeneous. Lokhu buqotho obubonakalayo obuthuthukisiwe buhumusha ukumelana okuthuthukisiwe ngokumelene nokukhathala, ukugqwala, nokuguga, okunweba impilo yesevisi ye-shaft nokunciphisa ingozi yokwehluleka ngaphambi kwesikhathi.

Ngokungeziwe ezicini zazo zokulungisa nokunemba kobukhulu, izinti ze-piston ezibunjiwe zinikeza ukuguquguquka ekukhetheni impahla, okuvumela abakhiqizi ukuthi balungise ukwakheka kwe-shaft ukuze kuhlangatshezwane nezidingo ezithile zokusebenza. Izinsimbi ezihlukahlukene kanye nama-alloys kungakhiwe kube yizinduku ze-piston, okuhlanganisa i-carbon steel, i-alloy steel, insimbi engagqwali, i-titanium, nama-alloys asekelwe ku-nickel, ngayinye inikezela ngezakhiwo ezihlukile ezifanele ukusetshenziswa okuhlukile. Ama-piston rods angabuye enziwe ngendlela oyifisayo ngezici ezengeziwe ezifana nokhiye, izintambo, ama-splines, nama-flange, okuthuthukisa ukusebenza kwawo nokuhambisana nezingxenye zokukhwelana. Kungakhathaliseki ukuthi isetshenziswa emishinini yezimboni esindayo noma amathuluzi anembayo, izinti ze-piston ezifojiwe zinikeza onjiniyela nabaklami isisombululo esinokwethenjelwa nesingabizi kakhulu sokudlulisa amandla, izinto ezisekelayo ezijikelezayo, nokugcina ubuqotho bemishini.

Kafushane, izinti ze-piston ezibunjiwe zigqama ngamandla azo akhethekile, ukwethembeka, kanye nokuguquguquka, okuwenza abe izingxenye ezibalulekile ezinhlobonhlobo zezinhlelo zokusebenza kuzo zonke izimboni. Ngokusebenzisa izinzuzo zenqubo yokubumba, abakhiqizi bangakhiqiza izinti ze-piston ezibonisa izakhiwo zemishini ephakeme, ukunemba kobukhulu, nobuqotho bezinto ezibonakalayo uma kuqhathaniswa nezinye izindlela zokukhiqiza. Kungakhathaliseki ukuthi zingaphansi kwemithwalo ephezulu, izindawo ezinokhahlo, noma izimo zokusebenza ezinzima, izinti ze-piston ezibunjiwe zinikeza ukusebenza okungenakuqhathaniswa nokuphila isikhathi eside, okuqinisekisa ukwethembeka nokusebenza kahle kwemishini ebucayi nemishini.
