Impamvu Imashini Yicyubahiro ikenewe mugukora impeta ya Piston
Impeta ya piston igomba kuba ifitebidasanzwe geometrie nubuso burangijekwemeza:
BirakwiyeIkidodohagati ya piston na silinderi
Kugenzurwafirime ya peterolihejuru ya silinderi
Ntarengwaguterana no kwambaramugihe cya moteri
Nyuma yuburyo nkaguhindukira, gusya, no gukubitaimpetadiameter y'imbere (ID), diameter yo hanze (OD), namu masoirashobora kuba ifite:
Ibimenyetso byo gutunganya microscopique
Kugoreka gato (hanze - ya - kuzenguruka, taper)
Ubuso butemewe bwo kubika amavuta no gukora - muri
Rero,icyubahiro kirasabwaKuri:
Kugeramicron - urwego ruzengurutse na diameter nezay'irangamuntu cyangwa OD.
GutezimbereUbuso bwo kurangiza no gutwara ibintuyo kunyerera neza kuri silinderi bore.
Kubyara amicrotextureifata amavuta yo gusiga neza.
Kurahoibimenyetso by'ibikoresho bisigayeno gutunganya geometrie nyuma yo kuvura ubushyuhe cyangwa gusya.
Imikorere yimashini yicyubahiro mubikorwa bya Piston
| Imikorere | Ibisobanuro |
|---|---|
| Igipimo Cyuzuye | Ingano yanyuma yimpeta ID / OD kugeza muri ± 0.001–0.002 mm. |
| Gukosora no gukosora Cylindricity | Kurandura kugoreka guterwa no kuvura ubushyuhe cyangwa gutunganya mbere. |
| Ubuso Kurangiza Gutezimbere | Kugera ku ndorerwamo - nka cyangwa ubuso bwa plateau (Ra ≈ 0.1–0.3 µm). |
| Ubuso bwo kubika amavuta | Bibyara micro - umusaraba - ibyatsi cyangwa ibibaya byububiko kugirango bisizwe neza. |
| Kugabanya Ubuvanganzo no Kwambara | Kongera imikorere ya piston impeta no gukora neza moteri. |
Uburyo Igikorwa Cyicyubahiro Cyakozwe (Intambwe - na - Intambwe)
1. Gutegura Igikorwa
Impeta ya piston nayo ifatanyekugiti cyecyangwa muriibirindirokuri amandel.
Imashini yicyubahiro yashyizweho ukurikijeingano yimpeta nibikoresho(bikunze guterwa ibyuma, ibyuma, cyangwa molybdenum - impeta zometseho).
2. Gushiraho Igikoresho
A kubaha mandel cyangwa umutweyashyizwemoamabuye abrasiveni Byakoreshejwe.
Ubusanzwe abrasivesdiyama, CBN (cubic boron nitride), cyangwa oxyde ya aluminium, ukurikije ubukana bwimpeta no kurangiza ibisabwa.
Amabuye nikwaguka, gukoresha igitutu kimwe hejuru yimbere cyangwa hanze.
3. Gukora ibikorwa
(a) Gusezerana no Kwimuka
Umutwe wicyubahiroKuzunguruka(mubisanzwe 200-600 rpm) mugiheGusubiranamokuri frequency nyinshi (inkoni 20-60 / min).
Uku guhuza gukomatanya gukata neza, hejuru kandi birashobora kubyara amicro - umusaraba - icyitegererezoigihe bibaye ngombwa.
(b) Kugenzura Umuvuduko no Kugaburira
Hydraulic cyangwa servo - yagenzuwe yagutse ikoresha igitutu gihoraho kugirango habeho no gukuraho imigabane.
Gukuraho ibikoresho ni bike - mubisanzwe5–20 µm- ariko hamwe na geometrike yukuri.
(c) Ubukonje
Kubaha amavuta cyangwa ibicurane bya sintetike bihanagura ibice byiza, amavuta, kandi bikonjesha ibihangano byakazi.
4. Gukurikirana no gupima
Muri - inzira yo gupimacyangwasisitemu yo gupima ikireregukurikirana ingano ya bore cyangwa indangamuntu mubyukuri - igihe.
Ingano yikora ifunga - off yemeza ko impeta yose yujuje kwihanganira.
Kubyinshi - umusaruro mwinshi,byinshi - imashini izunguruka cyangwa umubumbe wimashinizikoreshwa mugihe kimwe cyo kuzamura impeta nyinshi.
5. Kurangiza (Plateau cyangwa Mirror Honing)
Urupapuro rwanyuma rukoreshabyiza - grit amabuyekoroshya ubuso hejuru mugihe usize amavuta - kugumana ibibaya.
Iyi "ikibaya"ikora imiterere igenzurwa igabanya kwambara mugihe moteri yambere ikora - mugice.
Ibisubizo Ubuso nibiranga Ibipimo
| Parameter | Agaciro gasanzwe | Intego |
|---|---|---|
| ID / OD Ubworoherane | ± 0.001–0.002 mm | Ikidodo cyuzuye gikwiye muri piston groove na silinderi bore |
| Kuzunguruka | Ntibiri munsi cyangwa bingana na 1.0 µm | Kuzunguruka neza hamwe nigitutu kimwe |
| Ubuso Bwuzuye (Ra) | 0.1–0.3 µm | Kuringaniza kunyerera no kugenzura amavuta |
| Umusaraba - Fata Inguni | Impamyabumenyi 20 - 40 dogere (niba bikenewe) | Kubika amavuta neza no gusiga amavuta |
| Ikigereranyo cya Plateau | 60–80% | Kwihuta byihuse - no kwambara bike |
Kubaha Iboneza Impeta ya Piston
| Andika | Ibisobanuro | Gusaba |
|---|---|---|
| Kubaha imbere | Hone diameter y'imbere (kuri piston groove ikwiye) | Bikunze kugaragara |
| Icyubahiro cyo hanze | Kurangiza diameter yo hanze (kubutaka bwa silinderi) | Byakoreshejwe mugucunga neza impeta-bore Imigaragarire |
| Flat Surface Honing | Irangiza impande zimpeta | Kugirango kunyerera neza muri piston |
| Imashini zubaha imibumbe | Imirongo myinshi ihinduranya impeta nyinshi icyarimwe | Hejuru - imirongo itanga umusaruro |
Incamake
| Icyerekezo | Ibisobanuro |
|---|---|
| Dukeneye icyubahiro | Kugirango ugere ku busobanuro buhanitse, bworoshye, n'amavuta - hejuru yisubiraho hejuru yimpeta ya piston kugirango ushireho moteri nziza kandi wambare ubuzima. |
| Imikorere nyamukuru | Gukosora ibipimo, kuzamura uruziga, kurangiza hejuru, no gusiga amavuta. |
| Uburyo bwo Gutunganya | Kugenzura gukata gukuramo ukoresheje kuzunguruka no gusubiranamo amabuye munsi ya coolant flow. |
| Ibisubizo | Impeta ihoraho ya geometrie, guterana hasi, kugenzura amavuta meza, no kongera igihe kirekire mumikorere ya moteri. |
