Muri moteri yimodoka ,.silindiri boresbiri mubintu bikomeye cyane - bigira ingarukaimikorere ya moteri, gukoresha amavuta, gukoresha peteroli, no kuramba.
Nyuma yuburyo nkagukina, kurambirana, na kimwe cya kabiri - kurangiza, imyanda ya silinderi iracyafite:
Ibimenyetso by'ibikoresho hamwe n'ubuso budasanzwe
Shiraho amakosa(hanze - ya - kuzenguruka, taper)
Imyitwarire isigaye hamwe nibibanza bikomeye
Kubwibyo, aimashinini Nka Nkauburyo bwa nyuma bwo gutunganyaKuri:
Kugera kuridiameter neza na geometriebisabwa kuri piston - kugeza - silinderi ikwiye.
Tanga aumusaraba - gukuramo ubusoibyo bituma amavuta agumana neza kandi asiga amavuta.
Kurahoumunota wibikoresho(mubisanzwe 0.02–0.1 mm) kubigerahomicron - urwego rwukuri.
Gutezimbereubusugire bwubuso, kugabanya guterana amagambo, no kwaguraubuzima bwa moteri.
Imikorere yimashini yicyubahiro mubikorwa byo guhagarika moteri
| Imikorere | Ibisobanuro |
|---|---|
| Ibipimo Byukuri | Kugera ku kwihanganira gukomeye - mubisanzwe ± 0.002 mm - muri diameter. |
| Ubuso Kurangiza Kugenzura | Bitanga ubuso bwiza (Ra ≈ 0.2–0.4 µm) bubereye gufunga impeta ya piston no gusiga. |
| Gukosora Geometrike | Ikosora uburinganire, kugororoka, hamwe na silindrike amakosa yasizwe mbere yo kurambirwa cyangwa gucukura. |
| Imiterere yimiterere | Bitanga ibyifuzoumusaraba - icyitegererezo(mubisanzwe dogere 30–45 dogere) yo kubika amavuta. |
| Kuruhuka Stress | Kuraho ibyangiritse hejuru yubushakashatsi bwambere kandi byongera imbaraga zumunaniro. |
Uburyo Igikorwa Cyicyubahiro Cyakozwe (Intambwe - na - Intambwe)
1. Kwitegura
Guhagarika moteri yashyizwe kumashini ya honing.
Cylinder bores ihujwe naumurongo.
A igikoresho cyo kubaha (mandel)ifite ibikoreshoamabuye abrasivenakuyobora inkwetoni Byahiswemo Bishingiye ku bunini bwa bore n'ibikoresho (mubisanzwe bikozwe mu cyuma cyangwa aluminiyumu hamwe na linine).
2. Gukora ibikorwa
(a) Gusezerana ibikoresho
Mandel yaguka mumazi cyangwa mumashini kugirango akande amabuye abrasive byoroheje kurukuta rwa bore.
(b) Guhinduranya icyarimwe no gusubiranamo
Umutwe wicyubahirokuzunguruka (100-300 rpm)mugihegusubiranamo mu buryo (10-30 m / min)imbere.
Iyimuka ihuriweho irema iumusaraba - icyitegererezohejuru ya silinderi.
(c) Kugenzura Gukuraho Ibikoresho
Amabuye abrasive yatemye hejuru ya microscopique hejuru.
Inzira irakurikiranirwa hafiubunini bwa bore, geometrie, hamwe nubuso burangije.
Coolant (mubisanzwe amavuta yamavuta cyangwa emuliyoni) ikoreshwa kuri:
Kuraho imyanda
Gira ubukonje
Gusiga amavuta ibikorwa
3. Automatic Muri - Igipimo cyo gupima
CNC igezweho cyangwa servo - imashini igenzura ikoreshwa:
Ibipimo byo mu kirere cyangwa LVDTsgupima bore diameter mugihe nyacyo
Kugenzura ibitekerezoguhita uhindura igitutu cyamabuye cyangwa uburebure bwa stroke
4. Kurangiza na Plateau Honing
Akenshi abibiri - icyiciro cyicyubahiro:
Icyubahiro gikabije:Kuraho amakosa akomeye yimiterere kandi igera hafi ya {{0} size ingano yanyuma.
Kurangiza cyangwa plateau honing:Koresha abrasives nziza kugirango ukore ubuso hamweimpinganaamavuta - kugumana ibibaya- byiza kuri ring piston ikora - muri.
Ibisubizo Ibiranga Ubuso
| Parameter | Agaciro gasanzwe | Intego |
|---|---|---|
| Kuzenguruka | Ntabwo munsi cyangwa bingana na 2 µm | Kugenda neza piston |
| Ubuso bukabije (Ra) | 0.2–0.4 µm | Kugenzura amakimbirane |
| Umusaraba - inguni | Impamyabumenyi 30 - 45 | Kugumana amavuta meza |
| Ikigereranyo cya Plateau | 50–70% | Kugabanya kwambara mugihe cyo kuruhuka - muri |
Incamake
| Icyerekezo | Ibisobanuro |
|---|---|
| Dukeneye icyubahiro | Kugirango ugere kubisobanuro bihanitse, kurangiza neza, hamwe namavuta - retometive geometrie muri moteri ya silinderi. |
| Imikorere nyamukuru | Gukosora ibipimo, kurangiza hejuru, gushiraho imiterere, kugabanya imihangayiko. |
| Uburyo bwo Gutunganya | Kuzunguruka no gusubiranamo amabuye abrasive imbere muri bore kugirango akureho ibintu byiza no gukora microtexture igenzurwa. |
| Ibisubizo | Piston itunganijwe - gufunga silinderi, gukoresha amavuta make, ubuzima bwa moteri ndende, no gukora neza. |
