Kuyini ukuzala okuphezulu?

Ukufaka i-superfinishing kuyindlela yokushelela okuwukunyakaza kokuphakelayo ukuze kuzuzwe ukugaya okuncane.

Ingaphezulu ngaphambi kokuqedwa okuphezulu ngokuvamile liphenduka ngokunemba futhi liphansi. Ikakhulukazi, isho indlela yokucubungula eshelelayo esebenzisa ingcindezi encane kucezu lokusebenza ngethuluzi lokugwaza elihlaziywe kahle (itshe likawoyela) ngaphansi kokugcotshwa okuhle nezimo zokupholisa, futhi lenza ukunyakaza kwe-oscillation okusheshayo nokufushane okuphindaphindayo kucezu lokusebenza oluzungeza endaweni ethile. isivinini ekuqondeni kokuzungeza kwesiqephu esomile esiqondile.

Iyini indima yokuthwala i-superfining?

Enkambweni yokukhiqiza yama-rolling bearings, i-superfinishing iyinqubo yokugcina yokuthwala indandatho yokucubungula, edlala indima ebalulekile ekunciphiseni noma ekuqedeni ukuphambuka kwesiyingi okushiywe ngokugaya ukucubungula, ukulungisa iphutha lomumo womsele, ukucwenga ubulukhuni bayo obuphezulu, ukuthuthukisa ukuguquguquka kwesiyingi. izakhiwo zomzimba nezomshini zendawo, ukunciphisa ukudlidliza nomsindo we-bearing, kanye nokwenza ngcono umsebenzi wokuthwala.

Ingahlanganiswa kulezi zici ezintathu ezilandelayo

1. Kunganciphisa ngempumelelo ukuzungeza. Enqubweni yokuqeda kakhulu, ukuze kuqinisekiswe ukuthi itshe likawoyela lihlala lisebenza endaweni yegagasi futhi alixhumani nomkhombe, i-arc yetshe likawoyela lithintana nendawo yokusebenza.≥ubude begagasi be-waviness ebusweni bomsebenzi, ukuze ingcindezi yokuxhumana ye-crest ibe mkhulu, futhi ukuphakama kwe-convex kuyasuswa, ngaleyo ndlela kuncishiswe ukuzulazula.

2. Thuthukisa iphutha le-groove lomjaho ophethe ibhola. Ukuqedela kakhulu kungathuthukisa ngempumelelo iphutha le-groove cishe elingama-30% wemigwaqo yomjaho.

3. Ingaveza ukucindezeleka okucindezelayo ebusweni bokugaya okuhle kakhulu. Enqubweni yokuqeda phezulu, ukuguqulwa kwepulasitiki okubandayo kukhiqizwa ikakhulukazi, ukuze emva kokuqedwa okuphezulu, ukucindezeleka okusalayo okucindezelayo kwakhiwa phezu kwendawo yokusebenza.

4. Ingakwazi ukwandisa indawo yokuxhumana yendawo yokusebenza ye-ferrule. Ngemuva kokuphothula okukhulu, indawo ephethe ukuthintana kwendawo yokusebenza ye-ferrule ingakhuphuka isuka ku-15% ~ 40% ngemuva kokugaya iye ku-80% ~ 95%.  

Iqukethe inqubo yokuqedela:

1. Ukusika ama-bearings

 

Lapho ingaphezulu letshe lokugaya lithintana nesiqongo se-convex sendawo yomjaho onzima, ngenxa yendawo encane yokuxhumana namandla amakhulu endaweni yeyunithi, ngaphansi kwesenzo sokucindezela okuthile, itshe lokugaya kuqala isenzo "sokusika okuhlanekezelwe" sesiqephu sokusebenza esithwalayo, ukuze ingxenye yezinhlayiya ezilumayo ebusweni betshe lokugaya iwe futhi ibe yisiqephu, iveze okusanhlamvu okusha okuhlabayo okubukhali kanye nemiphetho enqunyiwe. Ngesikhathi esifanayo, i-surface bump ye-workpiece ethwala inqunywa ngokushesha, futhi ungqimba wokuwohloka kwe-crest kanye nokugaya ebusweni bomsebenzi othwalayo kususwa ngokusika nokuhlehla. Lesi sigaba sibizwa ngokuthi yisigaba sokusika, futhi sikulesi sigaba lapho ingxenye enkulu yemali yensimbi isuswa khona.

2. Ukusika isigamu sama-bearings

Njengoba umshini uqhubeka, ingaphezulu le-workpiece elithwalayo lihamba kancane kancane. Ngalesi sikhathi, indawo yokuxhumana phakathi kwetshe lokugaya kanye nobuso be-workpiece iyanda, ingcindezi yendawo ngayinye iyancipha, ukujula kokusika kunciphisa, futhi umthamo wokusika uyancipha. Ngesikhathi esifanayo, ama-pores ebusweni betshe lokugaya avinjiwe, futhi itshe lokugaya lisesimweni sokusika. Lesi sigaba saziwa njengesigaba sokusika isigamu sokuqeda ukuthwala, lapho izimpawu zokusika ebusweni bomsebenzi othwalayo ziba lula futhi zibe ne-gloss emnyama.

3. Isiteji sokuqeda

Lesi sigaba singahlukaniswa ngezinyathelo ezimbili: esinye yisigaba soguquko sokugaya, kanti esinye yisiteji sokugaya ngemva kokumiswa kokusika.

Isigaba soshintsho lokugaya:

Uhlamvu lwe-abrasive luyazilola, unqenqema lwezinhlamvu ze-abrasive lubushelelezi, i-chip oxide iqala ukufakwa endaweni engenalutho yetshe likawoyela, i-powder abrasive ivimbela ama-pores amatshe kawoyela, ukuze okusanhlamvu okulimazayo kunqunywe kuphela. ngobuthakathaka, okuhambisana ne-extrusion nokugaya, khona-ke ukuqina kwendawo yokusebenza kuyancishiswa ngokushesha, futhi ubuso betshe lamafutha buhlanganiswe ne-black chip oxide.

Misa isigaba sokugaya:

Itshe lamafutha kanye ne-workpiece friction komunye nomunye kuye kwaba bushelelezi kakhulu, indawo yokuxhumana yanda kakhulu, ukucindezela kwehla, okusanhlamvu okulimazayo kuye kwakwazi ukungena efilimini yamafutha kanye nokuxhumana ne-workpiece, lapho ukucindezelwa kwefilimu yamafutha kwendawo yokuthwala. ilingana nomfutho wetshe likawoyela, itshe lamafutha liyantanta. Ngesikhathi sokwakhiwa kwefilimu yamafutha, akukho mphumela wokusika. Lesi sigaba siyingqayizivele ekuqedeni okuphezulu.
