Uhlalutyo lweendawo ezichanekileyo ezenziwe ngoomatshini: iinxalenye zemikhono

1.Zintoni iindawo zemikhono?

Amalungu emikhono ahlulahlulwe ngokweempawu zawo zolwakhiwo: amakhonkco okuthwala ahlukeneyo kunye nemikhono exhasa umzimba ojikelezayo, imikhono yokubhola kunye nemikhono yesikhokelo kwi-fixture, imikhono yesilinda kwi-injini yokutsha yangaphakathi, iisilinda zehydraulic kwinkqubo yehydraulic, kunye ne-electro-hydraulic servo. iivalve.umkhono, umkhono wokupholisa kwi-spindle yombane, njl.

2. Iimpawu zesakhiwo seendawo zemikhono

Ubume kunye nobukhulu beengxenye zemikhono ziyahluka ngeendlela ezahlukeneyo zokusetyenziswa, kodwa isakhiwo ngokubanzi sinezi mpawu zilandelayo:
1) I-diameter d yesangqa sangaphandle ngokuqhelekileyo incinci kunobude bayo L, ngokuqhelekileyo L / d <5.
2) Umahluko phakathi kobubanzi bomngxuma wangaphakathi kunye nesangqa sangaphandle sincinci.
3) Iimfuno ze-coaxiality zezangqa zangaphakathi nangaphandle zokujikeleza ziphezulu.
4) Isakhiwo silula.

3. Iimfuno eziphambili zobugcisa zokulungiswa kweengxenye zemikhono

Iindawo eziphambili zeengxenye zemikhono zidlala indima eyahlukileyo kumatshini, kwaye iimfuno zabo zobugcisa zihluke kakhulu.Iimfuno eziphambili zobuchwephesha zezi zilandelayo:
(1) Iimfuno zobugcisa zomngxuma ongaphakathi.Umngxuma ongaphakathi ngowona mgangatho ubalulekileyo weendawo zemikhono ezidlala indima exhasayo okanye ekhokelayo.Ngokuqhelekileyo ihambelana ne-shaft ehambayo, isixhobo okanye ipiston.Inqanaba lonyamezelo lwedayamitha ngokubanzi yi-IT7, kwaye umkhono ochanekileyo wokuthwala yi-IT6;ukunyamezelwa kwemilo kufuneka jikelele kulawulwe ngaphakathi konyamezelo lokuvula, kwaye umkhono ochanekileyo kufuneka ulawulwe ngaphakathi kwe-1/3 ~ 1/2 yokunyamezela ukuvuleka, okanye nokuba ncinane;ixesha elide Ukongeza kwiimfuno zokujikeleza, umkhono kufuneka ube neemfuneko ze-cylindricity yomngxuma.Ukuze kuqinisekiswe iimfuno zokusetyenziswa kweengxenye zemikhono, uburhabaxa bomphezulu bomngxuma ongaphakathi yiRa0.16 ~ 2.5pm.Ezinye iinxalenye zemikhono echanekileyo zineemfuno eziphezulu, ukuya kuthi ga kwiRa0.04um.
(2) Iimfuno zobugcisa kwisangqa sangaphandle: Umphezulu wesangqa sangaphandle uhlala usebenzisa ukulungelelaniswa kokuphazamiseka okanye ukulungelelaniswa kwenguqu ukufanisa imingxuma kwibhokisi okanye isakhelo somzimba ukuze udlale indima exhasayo.Inqanaba lokunyamezela ubungakanani bayo yi-IT6~IT7;ukunyamezela imilo kufuneka kulawulwe ngaphakathi kokunyamezela kwedayamitha yangaphandle;uburhabaxa bomphezulu yiRa0.63 ~ 5m.
(3) Ukuchaneka kwendawo phakathi kweendawo ezinkulu
1) Ukubambisana phakathi kwezangqa zangaphakathi nangaphandle.Ukuba i-sleeve ifakwe emngxunyeni kumatshini ngaphambi kokulungiswa kokugqibela, ke iimfuno ze-coaxiality kwizangqa zangaphakathi nangaphandle zomkhono ziphantsi;ukuba umkhono ugqitywe ngaphambi kokuba ufakwe kumatshini, iimfuno ze-coaxiality ziphezulu., ukunyamezela ngokubanzi 0.005 ~ 0.02mm.
2) I-Perpendicularity phakathi kwe-axis yomngxuma kunye nobuso bokuphela.Ukuba ubuso besiphelo somkhono buphantsi komthwalo we-axial ngexesha lomsebenzi, okanye isetyenziswe njengesalathiso sokumisa kunye nereferensi yendibano, ngoko ubuso besiphelo bunomgangatho ophezulu we-perpendicularity kwi-axis yomngxuma okanye i-axial circular runout ifuna ukunyamezela ngokubanzi kwe-0.005 ~ 0.02mm .

4. Ukucubungula iteknoloji yeengxenye zemikhono

Ezona nkqubo ziphambili zokulungisa iinxalenye zemikhono kukurhabaxa kunye nokugqitywa komngxuma ongaphakathi kunye nomphandle wangaphandle, ngakumbi ukurhabaxa kunye nokugqitywa komngxuma ongaphakathi yeyona nto ibalulekileyo.Iindlela eziqhelekileyo ezisetyenziswayo zibandakanya ukubhola, ukuphinda, ukubethelwa, ukulola, ukugaya, ukuzoba kunye nokusila.Phakathi kwazo, ukugrumba, ukugaya, kunye nokugrumba ngokuqhelekileyo kusetyenziswa njengoomatshini obunzima kunye nokugqiba imingxuma, ngelixa ukugrumba, ukugaya, ukuzoba kunye nokugaya kusetyenziswa njengokugqiba.

5. Ukukhethwa kwezinto eziphathekayo kwi-sleeve parts machining

Ukukhethwa kwezinto eziluhlaza kwiingxenye zemikhono ikakhulu kuxhomekeke kwiimfuno zokusebenza, iimpawu zesakhiwo kunye neemeko zokusebenza zamalungu.Amalungu eSeti ayenziwe ngokubanzi ngezinto ezinje ngentsimbi, intsimbi, ubhedu okanye ubhedu, kunye nomgubo wesinyithi.Ezinye iinxalenye zemikhono ezineemfuno ezikhethekileyo zinokuthatha i-double-layer metal structure okanye zisebenzise umgangatho ophezulu we-alloy steel.Isakhiwo sesinyithi esine-double-layer sisebenzisa indlela yokuphosa i-centrifugal ukugalela umaleko we-alloy ye-Babbitt kunye nezinye izinto ezithwala i-alloy kudonga lwangaphakathi lwentsimbi okanye i-cast iron bushing.Ukusebenzisa oku Nangona le ndlela yokuvelisa yongeza iiyure ezithile zomntu, inokugcina iintsimbi ezingenayo i-ferrous kwaye iphucule ubomi benkonzo yokuthwala.
