Zvigadzirwa Zivo

Mhete yePiston isimbi yesimbi inoshandiswa kuisa mune iyo groove ye piston. Kune marudzi maviri ePiston zvindori: compression mhete uye mafuta mhete. Mhete yekumanikidza inoshandiswa kusimbisa musanganiswa unopisa mune chivakwa chengarava; Mhete yemafuta inoshandiswa kutsvaira mafuta akawandisa kubva kuCylinder.

Mhete ye piston isimbi yeiyo yelastic mhete ine hombe yekuwedzera yekuwedzera kuremara, iyo yakaunganidzwa muAngular Groove inoenderana nechikamu chemuchinjiko. Kudzokorora uye kutenderera piston mhete dzimba dzevadzvanyiriri hwegasi kana mvura kuti iite chisimbiso pakati peiyo mhete uye iyo silinda uye rimwe divi remhete uye rin'i groove.

Mhete dzePiston dzinowanzoshandiswa zvakanyanya mumakwikwi akasiyana siyana emasimba, sesheni dzepamhepo, majista, mahedheni, etny. zvimwe zvikamu zvekuita basa.

kukosha

Iyo piston mhete chikamu chepakati mukati meinjini yekumafuta, iyo inopedzisa chisimbiso cheganda rehuni pamwe chete neiyo cylinder, piston, etc. Nekuda kwekuita kwavo kwakasiyana kwemafuta, mhete piston inoshandiswa zvakare dzakasiyana. Mhete yekutanga yePiston yakaumbwa nekukanda, asi nekufambisira mberi kwehunyanzvi, simbi-pfuma inomirira pistoni yakazvarwa. , uye nekuenderera mberi kwekuvandudzwa kweinjini basa uye zvinodikanwa zvezvemamiriro ekunze

Basa

Izvo zvinoshandiswa zve piston mhete dzinosanganisira mabasa mana: Kuisa chisimbiso, kudzora mafuta (ekudzora mafuta), kupisa (kupisa (kupisa), uye kutungamira (tsigiro). Kuisa chisimbiso: zvinoreva kusimbisa gasi, kudzivirira gasi muchiratidzo kubva kumabhokisi kubva kuCrankcase Mhepo yekubhururuka haigone kuderedza simba reinjini, asi zvakare kudzikira mafuta, iro riri basa guru remhepo rin'i; Gadzirisaiwo mafuta (Oiri Dudziro Yemari Yakawandisa paCylinder Wall Firimu remafuta rinoita kuti madziro akaomeswa ekurongedza kweiyo cylinder, piston uye rin'i, iro riri basa rekuridza mhete. Mune injini dzazvino dzakakwirira-kumhanya, kutarisirwa kwakakosha kunobhadharwa kune chinzvimbo chePiston mhete kudzora iyo yemafuta firimu; Kupisa Kubata: Kupisa kwe pistoni kunoitwa kune cylinder liner kuburikidza ne piston mhete, kureva, inotonhorera. Sekureva kwedata akavimbika, 70-80% yekupisa kwe piston kumusoro kweiyo piston muCylinder Kufamba kwe pistoni, kunoderedza kuramba kupokana, uye kunodzivirira pistoni kubva pakugogodza cylinder. Kazhinji, iyo pistoni yeinjini injini inoshandisa maviri emhepo mhete uye imwe mhete yeoiri, nepo siel injini inowanzoshandisa madiki maviri mafuta uye imwe mhete. [2]

simba

Masimba arikuita piston mhete inosanganisira gasi rekumanikidza, iro simba rezvemusoro wekudzoreredza, rin'i rinoburitsa mwero wakadai sekutenderera kweshoko, radial kufamba, uye kufamba kwekutenderera. Mukuwedzera, nekuda kwehunhu hwayo hwekufamba, pamwe nekusagadzikana kwekutenderera, mhete ye piston isingaonekwe uye ne-axial kusarongeka, yekufambisa, etc. inokonzerwa ne-axial isina kujairika kufamba. Aya mafambiro asina kujairika anowanzo kudzivirira iyo piston mhete kubva pakushanda. Paunenge uchigadzira iyo piston mhete, inodikanwa kupa izere kutamba kune iyo yakafarirwa kufamba uye kudzora iyo isina kunaka.

inobata

Kupisa kwakanyanya kunogadzirwa nokuroverwa kunoendeswa kune iyo cylinder rusvingo kuburikidza ne piston mhete, saka inogona kutonhorera pistoni. Kupisa kwakasvibiswa kune cylinder rusvingo kuburikidza ne piston mhete inogona kazhinji kusvika makumi matatu kusvika makumi mana muzana ekupisa kwakanyudzwa pamusoro pe piston

mhepo yakasimba

Basa rekutanga rePiston rinoti kuchengeta chisimbiso pakati pe piston uye madziro eCylinder uye kudzora mweya kubhururuka kune zvishoma. Basa iri rinonyanya kuitwa negeji remuti Kuti udzivise kudzikisira pakati peiyo cylinder uye piston kana pakati pe cylinder uye rin'i. Mubate; Dzivirira kutadza kunokonzerwa nekuora kwemvura yeLubricating mafuta, nezvimwe

Kudzora kwemafuta

Basa repiri rePiston rin'i ndeyekunyatso bvarura mafuta eLubricating mafuta akasungirirwa neiyo silinda rusvingo uye chengetedza zvakajairika mafuta ekushandisa. Kana iwo magetsi anopiwa akawandisa, zvichayamwiswa muchiratidzo, chinowedzera kupindwa kwehunhu, uye kuchave nekupesvedzera kwakashata pakuita kweinjini nekuda kwebhoni deposits yakagadzirwa neCarustion.

Tsigiro

Nekuti pistoni iri diki diki pane iyo dhizaini yeiyo cylinder, kana pasina piston mhete, pistoni haina kugadzikana mu cylinder uye haigone kufamba vakasununguka. Panguva imwecheteyo, mhete iyi inodzivirirawo piston kubva pakubata zvakananga cylinder uye anoita basa rinotsigira. Naizvozvo, mhete ye piston inofamba ichikwira nekudzika mudutu, uye nzvimbo yayo inotsvedza inobvumidzwa zvizere nemhete.

Kumusoro Kurapwa

Nitreid mhete: kuomarara kweiyo nitride layer iri pamusoro 950hv, iyo brittlense iri giredhi 1, uye ine simba rekupesana nekupesana nekushora. Chrome-yakarongedzwa mhete: Iyo Chrome-yakarongedzwa denderedzwa yakanaka, compact uye yakaomarara, yakanaka kupfeka micro-mics-trocks, iyo inokodzera kuchengetwa kwemafuta anononoka. Nhoroondo yefoni yefoni: Kuburikidza nemakemikari, denderedzwa firimu rinoumbwa pamusoro peiyo piston mhete, inotamba nzizi yechigadzirwa uye zvakare inovandudza iyo yekutanga inomhanya-mukuita kwemhete. Oxidation Mhete: Pasi pemamiriro ekudziya zvakanyanya uye akasimba oxidant, firimu renzara rinoumbwa pamusoro pechinhu chesimbi, chine hurongwa hwekushambadzira, huni hwekurwisa uye kutaridzika kwakanaka. Kune PVD uye zvichingodaro.

Zvinoenderana nebasa

Kune marudzi maviri e piston rinoridza: gasi ridza mhete uye mafuta mhete. Basa renyaya yegesi ndeyekuona chisimbiso pakati pe piston uye cylinder. Zvinotadzisa kukwikwidza kwakanyanya uye kukwira kwegwenzi kubva ku cylinder kubva kuCrankcase muzvipfuyo zvakakura, uye panguva imwe chete zvinoitwa nePiston kuenda kuCylinger rusvingo, iyo yabva kure nemvura inotonhorera kana mweya.

Mhete yemafuta inoshandiswa kutsvaira mafuta akawandisa pagwenzi remadziro, uye coat firimu remafuta emagetsi, iro risingakwanise kungopinda muchirwi nekupisa, asi zvakare kuderedza kupfeka uye misodzi ye pistoni, piston mhete uye cylinder. kupokana kwekupokana. [1]

Piston inobatanidza tsvimbo gungano

Pfungwa huru dzegungano dzeDizil Jenareta Piston inobatanidza boka reboka dzinotevera:

1. Dzvanya-kukwana inobatanidza tsvimbo yemhangura sleeve. Paunenge uchiisa iyo yemhangura yemhete yedanda rinobatanidza, zvakanaka kuti ushandise priniki kana kusuka, uye usazvirova nenyundo; gomba remafuta kana mafuta groove pamhangura yemhangura inofanira kuwiriranwa neoiri gomba pane iyo gomba rekubatanidza retsvimbo kuti ive nechokwadi chekusimbisa kwayo

2. Unganidza iyo pistoni uye tsvimbo inobatanidza. Kana uchiunganidza pistoni uye tsvimbo inobatanidza, teerera kune yavo chinzvimbo uye kutaridzika.

Matatu, akangwara akaiswa piston pini. Iyo piston Pin uye iyo PIN gomba ndiko kupindira kwakakodzera. Paunenge uchiisa, tanga kuisa pistoni mumvura kana mafuta uye kunyange kuzvipisa kusvika 90 ° C ~ 100 ° C. Mushure mekubvisa, isa tie tete munzvimbo yakakodzera pakati pePiston Pin zvigaro zvigaro, uye wobva waisa iyo yemafuta-yakafukidzwa piston piston pini mugwara rakatemerwa. mu piston pin gomba uye iyo inobatanidza tsvimbo yemhangura sleeve

Chechina, kuisirwa kweiyo piston mhete. Paunenge uchiisa piston mhete, teerera kune chinzvimbo uye kurongeka kwechirevo chimwe nechimwe.

Yechishanu, isa boka rekubatanidza rand.
