Cummins Moteri igice Moteri Piston 4095489/4089357/4095490 kuri Cummins QSK23 Moteri

Imiterere nihame ryakazi rya piston

Piston yose irashobora kugabanywamo ibice bitatu: ikamba rya piston, umutwe wa piston hamwe nijipo ya piston.

Igikorwa nyamukuru cya piston ni ukurwanya igitutu cyaka muri silinderi no kohereza izo mbaraga kuri crankshaft ukoresheje pin ya piston uhuza inkoni.Mubyongeyeho, piston ikora icyumba cyo gutwika hamwe n'umutwe wa silinderi hamwe nurukuta rwa silinderi.

Ikamba rya piston nigice cyicyumba cyo gutwika, kubwibyo akenshi bikozwe muburyo butandukanye.Byinshi, moteri ya lisansi piston ifata hejuru iringaniye cyangwa hejuru kugirango ishobore gutuma urugereko rwaka rwuzura mu miterere, ntoya mu bushyuhe bw’ubushyuhe, kandi byoroshye mubikorwa byo gukora.Piston ya convex ikoreshwa kenshi muri moteri ya lisansi ebyiri.Ikamba rya piston ya moteri ya mazutu ikozwe mubyobo bitandukanye.

Umutwe wa piston nigice kiri hejuru yintebe ya piston.Umutwe wa piston ufite impeta ya piston kugirango wirinde ubushyuhe bwinshi na gaze yumuvuduko mwinshi winjira mu gikarito, kandi icyarimwe kibuza amavuta kwinjira mu cyumba cyaka;ubushyuhe bwinshi bwakuwe hejuru ya piston nabwo bunyura mumutwe wa piston Igice kinyuzwa kuri silinderi, hanyuma kikanyura mumashanyarazi.

Ibice byose munsi ya piston impeta yitwa piston skirt.Igikorwa cyayo nukuyobora piston kwisubiraho muri silinderi no kwihanganira igitutu cyuruhande.Iyo moteri ikora, piston izunama kandi ihindurwe kubera umuvuduko wa gaze muri silinderi.Iyo piston imaze gushyuha, hari ibyuma byinshi kuri pin ya piston, bityo kwaguka kwayo bikaba binini kuruta ahandi.Mubyongeyeho, piston nayo izabyara guhindagurika munsi yigitutu cyuruhande.Nkigisubizo cyo guhindura ibintu hejuru, igice cyambukiranya ijipo ya piston gihinduka ellipse hamwe nigitereko kinini mu cyerekezo cya piston.Mubyongeyeho, kuberako ikwirakwizwa ryubushyuhe hamwe nuburemere bwa piston kuruhande rwerekezo ya axial, kwagura ubushyuhe bwa buri gice ni binini kandi bito.
