Urabona ibiganiro byinshi kubyerekeranye na shitingi igororotse mugutunganya insinga no gutunganya utubari, ariko inkuru yukuri ntabwo iri murutonde rwibisobanuro. Ari muri grime, cycle yubushyuhe, hamwe no gutandukana byoroshye ubona gusa nyuma yo gukora toni 50 zicyuma kinini. Umuntu wese yibanze ku gukomera, ariko niba intangiriro idakwiye, ni inkoni nziza, ihenze itegereje gutera umurongo.
Imyumvire yibanze: Gukomera ntabwo arikintu cyose
Iyo amaduka menshi cyangwa na OEM zimwe zerekana a shaft, icya mbere cyamakuru ni burigihe hejuru. HRC 58, 60, birashoboka. Nukuri, ukeneye kwambara birwanya aho imizingo ihurira. Ariko nakuyeho ibiti byujuje ubukana nyamara byananiye imburagihe. Kunanirwa ntibyari hejuru; cyari umunaniro utangiza nka 5mm hepfo. Intangiriro yibikoresho yari ifite ubukana bubi. Munsi ya cycle yikurikiranya imitwaro yo kugorora, cyane hamwe nibiryo bidahuye, niho itanga.
Aha niho guhitamo ibikoresho biboneka. Ntabwo ari ibyuma gusa cyangwa ibyuma bivanze. Kuri shitingi ibona imbaraga nyinshi zingirakamaro, ukeneye urwego-rukomeye hamwe ninziza nziza. Ikintu nka 4140 cyangwa 4340, gikoreshwa neza nubushyuhe kugirango ubone imiterere ihamye ya martensitike unyuze mubice. Nabonye imyambarire igerageza kuzigama igiciro hamwe nicyuma giciriritse giciriritse kandi induction ikomera hejuru. Irakora, kugeza itabikora - kandi ikiruhuko ni catastropique, ntabwo buhoro buhoro.
Twari dufite ikibazo numukiriya ukoresha umurongo wihuta wicyuma cyicyuma. Baryaga bakoresheje ibiti buri mezi 8. Ibisobanuro byasaga neza ku mpapuro. Twabonye kimwe mubice byananiranye, dukora isesengura ryibyuma, dusanga itandukaniro rikomeye muri microstructure yibanze - ibimenyetso byo kuzimya bidakwiye. Ubuso bwari bukomeye, ariko intangiriro yari ibintu bitandukanye, intege nke. Gukosora ntabwo byari ibintu bikomeye, ahubwo byari inzira igenzurwa cyane. Nubwoko bwibigo bya nuance nka Qingdao Qiangsenyuan Technology Co., Ltd. (QSY) gusobanukirwa kuva mu myaka yabo ya casting no gutunganya. Ntabwo bakata ibyuma gusa; bayobora ibintu byose bihinduka, nibyingenzi kubintu bitsindagiye nkibi.
Geometrie & Tolerances: Aho Theory Ihurira Imashini
Igishushanyo gisaba kwihanganira kugororoka, vuga, 0.05mm kuri metero. Kugerwaho kumusarani mwiza cyangwa gusya. Ariko ibyo biri mubyumba bigenzurwa nikirere. Ikizamini nyacyo ni mugihe uruzitiro rufunguye mumurongo ugororotse, mbere yapakiwe, hanyuma ugashyuha kugeza kuri 60 ° C hamwe nubushyuhe hamwe nubushyuhe bwibidukikije. Iraguma igororotse? Cyangwa bisaba gufata akantu gato?
Kwihanganira diameter kubinyamakuru byandika nibindi byago bya kera. Gukomera cyane, kandi ushobora guhura nigihe cyo kwishyiriraho cyangwa gufatwa no kwaguka kwinshi. Kurekura cyane, kandi ukabona kwambara nabi, kunyeganyega, hanyuma, wobble yangiza ukuri kugororotse. Nkunda inzibacyuho igenzurwa, rimwe na rimwe ndetse nkerekana icyerekezo gito-kiyobora kitari buri gihe ku icapiro risanzwe, kugirango itunganyirize umurima rishoboke nta mashanyarazi ya hydraulic hamwe nisengesho.
Noneho hariho iherezo. Ibinyamakuru bikenera gusya neza, akenshi kuri 0.4 Ra cyangwa byiza. Ariko ibice biri hagati yintebe zizunguruka? Urashobora kubona imashini zikoreshejwe cyangwa ndetse zikarangira. Hariho impamvu. Iyo miterere irashobora gufasha mubyukuri kugumana amavuta no gukwirakwiza ubushyuhe neza kuruta ubuso bwiza. Nibintu bito, bifatika wiga mubona ibi bice muri serivisi, ntabwo bivuye kubishushanya gusa.
Imbyino yo Gukora: Gukina va Imashini kuva mu kabari
Ku bunini busanzwe, a shaft ni Byakorewe Mububiko Byahimbwe Cyangwa Buzengurutse. Birahanurwa. Ariko kuri diametero nini, ibintu bigoye byingenzi (nka flanges cyangwa imiterere idasanzwe yo kugereranya), cyangwa mugihe umusaruro wibintu ari ikintu kinini cyigiciro, gukina biba bishimishije. Aha niho ubuhanga bwo gushinga bwambere.
Uruzitiro rushyizweho rukeneye inzira itagira inenge kugirango wirinde kugabanuka kwimbere imbere cyangwa guhuzagurika bihinduka impungenge. Ibyiza nuko ushobora kwegera net net, ukabika umwanya munini wo gutunganya kumyanda. Ikibi nuko ugomba rwose kugira ibizamini bikomeye bidasenya (NDT). Twakoze igeragezwa mumyaka yashize kumurongo munini wa diameter kumurongo wumuringa. Twajyanye na casting kugirango duhuze amazu yimyubakire. Ingingo ya mbere yatsinze igenzura ryose ariko yananiwe gukora ikizamini cya ultrasonic - agace gato, kegeranye na porosity zone neza ahantu hahanamye. Byagombaga gusiba. Ikigeragezo cya kabiri, hamwe no kuvugurura amarembo hamwe na riser igishushanyo mbonera, cyari gikomeye.
Ubu ni ubwoko bwubushobozi ushakisha mubitanga. Isosiyete nka QSY, hamwe namateka maremare muri Igikonoshwa na gushora imari, irashobora kuyobora aya mahitamo. Igikonoshwa ni cyiza kubice byibyuma nicyuma hamwe nubuso bwiza burangiye kandi buringaniye, mugihe ishoramari ryakozwe kurwego rushimishije, ruvanze-ruremereye. Bashobora gusuzuma niba igiti cyakozwe neza kuva mukibaho gikomeye Imashini ya CNC ibigo cyangwa niba inzira yo gukina ikora neza, kandi bafite ubumenyi bwa metallurgjiya kugirango bagaragaze uburenganzira nikel cyangwa cobalt kwambara cyane cyangwa ibidukikije byangirika.
Uburyo bwo Kunanirwa: Inkuru Shafts Zivuga
Wiga byinshi mubice byacitse kuruta igice cyuzuye. Ubuso bwavunitse nigitabo cyamateka. Ivunika risukuye, indege imwe hamwe nibimenyetso byinyanja biva kumurongo umwe? Kunanirwa kunanirwa. Bitangirira kumyitozo yibibazo - birashoboka ko imfuruka ityaye kumpera yumuhanda utarasakaye neza, cyangwa ikimenyetso cyibikoresho byakoraga nka micro-crack.
Ndibuka igiti cyakomeje kogosha urufunguzo rwa Woodruff. Umuntu wese yakomeje kuzamura ibikoresho byingenzi. Hanyuma, twarebye inzira nyine. Yakozwe hamwe nurusyo rusanzwe rusize, hasigara hasi, kare. Igice cyatangiriye aho. Igisubizo cyari amabwiriza yoroshye kumashini: Shyira radiyo mururwo rufunguzo rwo hasi, nini nkuko igishushanyo kibyemerera. Ntabwo wigeze unanirwa. Niminota itanu yo gutunganya ibintu byinshi moderi ya CAD itanerekana.
Ikindi gisanzwe, kunanirwa byoroshye ni torsional umuyaga-up. Ku kugorora hamwe no kuzunguruka, uruziga rwohereza umuriro. Niba diameter idashushanyijeho umutwaro wa torsional, ubona gutandukana. Ibi ntibisenya igiti ako kanya; gusa bituma uburyo bwo kugorora budahuye kandi bwangiza ubuziranenge bwibicuruzwa. Urashobora kwirukana ikibazo kumayinga, ugahindura imizingo, mbere yuko utekereza kugenzura niba igiti ubwacyo kizunguruka munsi yumutwaro.
Kwishyira hamwe & Ibyiyumvo bya Shaft nziza
Ubwanyuma, a shaft ntabwo ari ikirwa. Nibice bya sisitemu ifite ibyuma, amazu, imizingo, hamwe nimashini. Igiti cyiza gishobora kurekurwa no guhuza nabi mugihe cyo kwishyiriraho. Buri gihe dushimangira uburyo bwo kwishyiriraho: koresha lazeri ihuza, ntabwo urwego rwumwuka. Reba imyanda ahantu henshi ukurikije uburebure bwa shaft imaze kwicara mubitereko byayo, ntabwo ari ku ntebe gusa.
Hariho kandi ibyiyumvo bidafatika byunvikana neza. Impirimbanyi. Iyo uzunguruka kuruhuka ruhoraho mbere yo kwishyiriraho, bigomba guhinduka neza nta bibanza biremereye. Ubuso bugomba kuba busukuye, udakoresheje imirongo yabatangabuhamya ushobora gufata urutoki. Uburemere bugomba kumva bukwiranye nubunini bwabwo nibikoresho - ikimenyetso cyubucucike buhoraho, cyane cyane muri verisiyo.
Abatanga isoko babona aribo bagiye hasi muruganda ubwabo. Bazi ko uruhare rwabo rugomba gukorera ahantu habi, kunyeganyega, ahantu hashyushye. Ntabwo ari igishushanyo kuri bo gusa. Iyo ukoranye numufatanyabikorwa utanga ubuhanga bwa casting kubwinyangamugayo nibintu byuzuye Imashini ya CNC kubikorwa byanyuma nibikorwa - nka serivise ihuriweho wasanga muri firime ifite umwirondoro wa QSY - ntabwo ugura ibice gusa. Urimo kugura igice cyo kwizerwa. Nibyo bituma umurongo wo gutunganya ukora, guhinduranya nyuma yo kwimuka. Intego ni uko igiti aricyo kintu cyanyuma abakozi bashinzwe kubungabunga batekereza.
