I-Working Principle of Zinc-Aluminium Alloy Bushings

Ukuqina Okuphezulu Ne-Wear-I-Resistant Matrix: I-Zinc{1}}i-aluminium alloy iqukethe cishe u-27% we-aluminium. Ngemva kokuqiniswa, inani elikhulu le-aluminium{4}}izigaba zokuqinisa i-zinc intermetallic compound ziyakhiwa, kuthuthukisa kakhulu ubulukhuni namandla aqinile (kufika ku-400–430 MPa), ihlinzeka ngesakhiwo esizinzile sokusekela esincanyana phakathi nokungqubuzana, nokunciphisa ukuguga.

I-self-Indlela Yokuzigcoba:
Kuma-graphite-ashumekiwe amahlahla,{1}}i-graphite emsulwa ephezulu ishunyekwa ezimbotsheni ezingaphezulu ze-matrix (evala u-20%–30% wendawo yokungqubuzana). Ngesikhathi sokungqubuzana, i-graphite idlulela endaweni yokuhlangana ngaphansi kwesenzo esishisayo nesemishini, yenze ifilimu yokugcoba eqhubekayo, inciphisa i-friction coefficient ibe ngu-0.06–0.12, ithola uwoyela{7}}ukugcoba kwamahhala.

Kuwoyela onezimbotshana{0}}aqukethe izakhiwo ze-polymer, uwoyela{1}}izinto ze-polymer ezifakiwe zishunyekwa ngaphakathi kwe-bushing, eqhubeka ekhipha okokugcoba ngohlelo "lwe-micro{2}}lokunikezwa kukawoyela", ehlisa insimbi eqondile-ku{4}}ukuthintana kwensimbi.

Ukugcotshwa Okusizwa Ngokwesakhiwo: Amanye amadizayini afaka izimbobo zikawoyela nezinhlelo zokuvala i-silicone, okuvumela uwoyela wangaphandle ukuthi ungeze ukugcoba, nokusebenzisa ukunwebeka kwe-silicone ukuvala izimbobo ngokuzenzakalelayo, ukuvimbela ukuvuza kukawoyela kanye nokwelula izikhawu zokulungisa.

I-Lightweight kanye Nezinzuzo Zezindleko: Ukuminyana kwezinki{0}}ze-aluminium alloy cishe ku-5.0 g/cm³, 40%–45% lighter kunealloys yethusi, futhi izindleko ze-raw material zingu-30%–40% kuphela wezinto ezisekelwe ekhopha, okuyenza ifanelekele izinhlelo zokusebenza ezizwelayo isisindo nezindleko.
