Ukuhlaziywa kwezingxenye ezijwayelekile ezenziwe ngomshini: izingxenye zemikhono

1.Ziyini izingxenye zemikhono?

Izingxenye zemikhono zihlukaniswa ngokwesakhiwo sazo: izindandatho ezithwele imikhono ehlukahlukene esekela umzimba ojikelezayo, imikhono yokubhoboza kanye nemikhono eqondisayo endaweni, imikhono yamasilinda enjinini evuthayo yangaphakathi, amasilinda amanzi ohlelweni olusebenza ngamanzi, kanye ne-electro-hydraulic servo. ama-valve.umkhono, umkhono wokupholisa ku-spindle kagesi, njll.

2. Izici zesakhiwo sezingxenye zemikhono

Isakhiwo nosayizi wezingxenye zemikhono ziyahlukahluka ngokusetshenziswa okuhlukene, kodwa isakhiwo ngokuvamile sinalezi zimpawu ezilandelayo:
1) Ububanzi d bendilinga yangaphandle ngokuvamile buncane kunobude bawo L, ngokuvamile L/d<5.
2) Umehluko phakathi kobubanzi bomgodi ongaphakathi kanye nendilinga yangaphandle mncane.
3) Izidingo ze-coaxiality zendilinga yangaphakathi nengaphandle yokuzungezisa ziphakeme ngokuqhathaniswa.
4) Isakhiwo silula.

3. Izidingo eziyinhloko zobuchwepheshe zokucubungula izingxenye zemikhono

Izindawo eziyinhloko zezingxenye zemikhono zidlala indima ehlukene emshinini, futhi izidingo zabo zobuchwepheshe zihluke kakhulu.Izidingo zobuchwepheshe eziyinhloko zimi kanje:
(1) Izidingo zobuchwepheshe zembobo yangaphakathi.Imbobo yangaphakathi iyindawo ebaluleke kakhulu yezingxenye zemikhono edlala indima yokusekela noma yokuqondisa.Ngokuvamile ifanelana neshaft ehambayo, ithuluzi noma ipiston.Izinga lokubekezelela ububanzi ngokuvamile i-IT7, futhi umkhono ophethe ukunemba yi-IT6;ukubekezelelwa komumo ngokuvamile kufanele kulawulwe ngaphakathi kokubekezelela imbobo, futhi umkhono onembe kakhudlwana kufanele ulawulwe ngaphakathi kwe-1/3~1/2 yokubekezelelana kwembobo, noma okuncane nakakhulu;isikhathi eside Ngaphezu kwezidingo eziyindilinga, umkhono kufanele ube nezidingo ze-cylindricity yembobo.Ukuze uqinisekise izidingo zokusetshenziswa kwezingxenye zemikhono, ubulukhuni obungaphezulu bembobo engaphakathi bungu-Ra0.16~2.5pm.Ezinye izingxenye zemikhono enembayo zinezidingo eziphakeme, ezifika ku-Ra0.04um.
(2) Izidingo zobuchwepheshe zendilinga yangaphandle: Indawo engaphandle indilinga ngokuvamile isebenzisa ukulingana kokuphazamiseka noma ukulingana koshintsho ukuze ifane nezimbobo ezisebhokisini noma kuhlaka lomzimba ukuze lidlale indima esekelayo.Izinga layo lokubekezelela usayizi wobubanzi yi-IT6~IT7;ukubekezelelana komumo kufanele kulawulwe ngaphakathi kokubekezelelana kobubanzi obungaphandle;ubulukhuni bobuso bungu-Ra0.63~5m.
(3) Ukunemba kwesikhundla phakathi kwezindawo ezinkulu
1) Ukubambisana phakathi kwendilinga yangaphakathi nengaphandle.Uma umkhono ufakwe emgodini emshinini ngaphambi kokucubungula kokugcina, khona-ke izidingo ze-coaxiality zemibuthano yangaphakathi nangaphandle yomkhono ziphansi;uma umkhono uqedwa ngaphambi kokufakwa emshinini, izidingo ze-coaxiality ziphakeme., ukubekezelelana ngokuvamile kungu-0.005 ~ 0.02mm.
2) I-Perpendicularity phakathi kwe-axis yembobo nobuso bokuphela.Uma ubuso bokuphela komkhono bungaphansi komthwalo we-axial phakathi nomsebenzi, noma busetshenziswa njengereferensi yokuma kanye nereferensi yomhlangano, khona-ke ubuso bokuphela bunombono ophezulu we-axis yembobo noma ukuphuma kwe-axial circular kudinga ukubekezelela ngokuvamile okungu-0.005~0.02mm .

4. Ukucubungula ubuchwepheshe bezingxenye zemikhono

Izinqubo eziyinhloko zokucutshungulwa kwezingxenye zemikhono ikakhulukazi ukugoqa nokuqedwa kwembobo engaphakathi nendawo yangaphandle, ikakhulukazi ukugoqa nokuqedwa kwembobo yangaphakathi yiyona ebaluleke kakhulu.Izindlela zokucubungula ezivame ukusetshenziswa zihlanganisa ukubhoboza, ukulungisa kabusha, ukubhoboza, ukulola, ukugaya, ukudweba nokugaya.Phakathi kwazo, ukubhoboza, ukugaya kabusha, kanye nokubhoboza ngokuvamile kusetshenziswa njengomshini onzima kanye nokuqeda imigodi kancane, kuyilapho ukubhola, ukugaya, ukudweba, nokugaya kusetshenziswa njengokuqeda.

5. Ukukhetha impahla yezingxenye zemikhono machining

Ukukhethwa kwezinto zokusetshenziswa zezingxenye zemikhono ikakhulukazi kuncike ezidingweni zokusebenza, izici zesakhiwo kanye nezimo zokusebenza zezingxenye.Izingxenye ezimisiwe ngokuvamile zenziwe ngezinto ezifana nensimbi, insimbi ecijile, ithusi noma ithusi, ne-powder metallurgy.Ezinye izingxenye zemikhono ezinezidingo ezikhethekile zingasebenzisa uhlaka lwensimbi oluphindwe kabili noma zisebenzisa insimbi ye-alloy yekhwalithi ephezulu.Isakhiwo sensimbi esinezingqimba ezimbili sisebenzisa indlela yokuphonsa eyi-centrifugal ukuthulula ungqimba lwe-Babbitt alloy nezinye izinto ezithwala ingxubevange odongeni lwangaphakathi lwensimbi noma insimbi ekhonjiwe.Ukusebenzisa lokhu Nakuba le ndlela yokukhiqiza yengeza amahora athile omuntu, ingonga izinsimbi ezingenayo insimbi futhi ithuthukise impilo yesevisi ye-bearing.
