Sebopeho le molao-motheo oa ho sebetsa oa piston

Piston eohle e ka aroloa likarolo tse tharo: moqhaka oa piston, hlooho ea piston le skirt ea piston.

Mosebetsi o ka sehloohong oa piston ke ho mamella khatello ea mollo ka har'a silinda le ho fetisetsa matla ana ho crankshaft ka phini ea piston le molamu o kopanyang.Ho feta moo, piston e etsa kamore e tukang hammoho le hlooho ea silinda le lebota la cylinder.

Moqhaka oa piston ke karolo ea kamore ea mollo, kahoo hangata e etsoa ka libopeho tse fapaneng.Haholo-holo, piston ea enjene ea peterole e nka karolo e ka holimo e bataletseng kapa bokaholimo ba sekoti ho etsa hore kamore ea mollo e kopane ka sebopeho, e nyane sebakeng sa ho qhala mocheso, 'me e be bonolo ts'ebetsong ea tlhahiso.Hangata li-piston tsa convex li sebelisoa lienjineng tse peli tsa peterole.Moqhaka oa piston oa enjene ea disele hangata o entsoe ka likoti tse fapaneng.

Hlooho ea piston ke karolo e ka holimo ho setulo sa piston.Hlooho ea piston e na le lesale la piston ho thibela mocheso o phahameng le khatello e phahameng ea khase ho kena ka har'a crankcase, 'me ka nako e ts'oanang e thibela oli ho kena ka kamoreng ea mollo;mocheso o mongata o kenngoa ka holim'a piston o boetse o feta hloohong ea piston Karolo e fetisetsoa ho cylinder, ebe e feta ka mokhoa o pholileng.

Likarolo tsohle tse ka tlas'a piston ring groove li bitsoa piston skirts.Mosebetsi oa eona ke ho tataisa piston ho khutlisa ka har'a silinda le ho jara khatello ea lehlakore.Ha enjene e sebetsa, piston e tla kobeha le ho holofala ka lebaka la khatello ea khase e ka har'a silindara.Ka mor'a hore piston e chese, ho na le tšepe e ngata ho piston, kahoo katoloso ea eona e kholo ho feta libaka tse ling.Ho feta moo, piston e tla boela e hlahise deformation ea squeeze tlas'a ketso ea khatello ea lehlakore.Ka lebaka la deformation e ka holimo, karolo ea sefapano sa seaparo sa piston e fetoha ellipse e nang le axis e kholo ka tsela ea piston ea piston.Ho phaella moo, ka lebaka la kabo e sa lekaneng ea mocheso le boima ba piston ho latela tataiso ea axial, katoloso ea mocheso ea karolo ka 'ngoe e kholo ebile e nyenyane.
