Yintoni uMsebenzi wePiston Pin kwiPiston?
2021-12-24
Umsebenzi wepiston yepiston kukudibanisa ipiston kunye nesiphelo esincinci sentonga yokudibanisa, kunye nokuhambisa amandla phakathi kwepiston kunye nentonga yokudibanisa.
Iphini yepiston inomthwalo womothuko ngamaxesha athile, kwaye iyazijula ngokwawo, kwaye isebenza phantsi kweemeko ezimbi zokuthambisa. Ke ngoko, ipiston pin iyafuneka ukuba ibe namandla okwaneleyo kunye nokuqina, ukuqina okuhle komphezulu, ukumelana nokunxiba okufanelekileyo, kunye nobunzima obulula. Izikhonkwane zepiston ngokuqhelekileyo zenziwe ngeesilinda ezingenanto, ezenziwe ngentsimbi ephantsi kwekhabhoni kunye nentsimbi ephantsi-carbon alloy. Umphezulu wangaphandle ufakwe i-carburized kwaye ucinywe ukwandisa ubunzima. Emva kokugqiba, igudiswa ukuba ibe nokuchaneka okuphezulu kunye nokugqitywa komphezulu.
Ulwakhiwo olusisiseko lwepiston yepiston ngumzimba otyebileyo we-tubular, kwaye ezinye zinezakhiwo eziguquguqukayo ezinqamlezayo ngokweemfuno zamandla alinganayo.
Kukho iindlela ezimbini zokuqhagamshela ipiston yepiston kumngxuma wesitulo sepiston kunye nentonga yokudibanisa isiphelo esincinci somngxuma: uqhagamshelo olugcweleyo kunye noqhagamshelo oludadayo.
Uqhagamshelo oludadayo olupheleleyo luthetha ukuba xa i-injini ikwiqondo lobushushu eliqhelekileyo lokusebenza, iphini yepiston inokujikeleza ngokukhululekileyo kumngxunya wesitulo sepiston kunye nentonga yokudibanisa umngxuma omncinci womkhono wentloko. Njengoko kuboniswe kumzobo, kunye noqhagamshelo olugcweleyo, i-piston pin inokumelana nomthwalo omkhulu wempembelelo, igqoke ngokulinganayo, kwaye ibe nobomi obude benkonzo, kodwa inkqubo yendibano inzima kakhulu. Xa udibanisa ipiston yealuminiyam kunye nepiston, ipiston kufuneka ifudunyezwe emanzini okanye kwi-oyile kwiqondo lobushushu le-70-90 ℃ ukwandisa umngxuma wesitulo sepiston phambi kokufaka ipiston. Ukuze uthintele ukujikeleza kwe-axial yepiston yepiston, amakhonkco e-snap nawo afakwe kuzo zombini iziphelo zesitulo sephini.
Ukudityaniswa kwe-semi-floating kuthetha ukuba indawo enye ilungisiwe phakathi kwepiston yepiston kunye ne-piston pin yesihlalo somngxuma kunye nentonga yokudibanisa umngxuma omncinci wesiphelo. I-piston yepiston ngokubanzi igxininiswe kwintonga yokudibanisa encinci. Kuba akukho ntshukumo ihambelanayo phakathi kwepiston yepiston kunye nentonga yokudibanisa, akukho mfuneko yeringi ye-snap ukunqanda indawo ye-axial yepiston yepiston, oko kukuthi, i-semi-floating yepiston yepiston ayinayo i-snap ring, kwaye apho. akukho bushing kwisiphelo esincinci sentonga yokudibanisa. I-semi-floating piston pin inokunciphisa ingxolo ye-injini kwaye isuse iingozi ezinokubakho ezibangelwa yi-snap ring. Isetyenziswa kakhulu kwiinjini zokukhanya ezinesantya esiphezulu, ezifana neCherokee neCheetah, njl njl. iimoto zisebenzisa le fomu.
