Hlukanisa phakathi kwama-bearings azigcobayo kanye nama-bearings afakwe uwoyela

 

Kuyiniokufakwe uwoyelaibhere?

Indlela yokugaya i-powder metallurgy inezimbobo futhi inezinzuzo zobuchwepheshe zokulungisa inani, usayizi, ukuma kanye nokusatshalaliswa kwama-pores ngokukhululeka enkambisweni yokukhiqiza. Isebenzisa izimbobo zomzimba okugaya, ifakwa u-10%-40% (ingxenye yevolumu) kawoyela wokugcoba, futhi isetshenziswa esimweni sokuhlinzekwa ngowoyela ngokwakho. Ngesikhathi sokusebenza, izinga lokushisa le-bearing liyakhuphuka, futhi njengoba i-coefficient yokwanda kukawoyela inkulu kuneyensimbi, ingena ngokuzenzakalelayo endaweni eshelelayo ukuze igcobe i-bearing. Ama-bearing afakwe uwoyela angasetshenziswa isikhathi eside namafutha owodwa, futhi avame ukusetshenziswa ezimweni lapho ukugcwalisa uphethiloli kungafanele.

 

Kuyiniukuzigcobaibhere?

Amabheringi azigcobayozihlukaniswe ngama-bearings azigcobayo ahlanganisiwe, ama-bearings azigcobayo aqinile, ama-bearings azigcobayo anezinto ze-bimetallic, kanye nama-bearings akhethekile azigcobayo.

 

Enye yezinhlobo ezinkulu zama-bearings azigcobayo aqinile (okubizwa ngokuthi i-JDB) yi-bearings entsha egcotshwe ngotshani enezici zombili ze-bearings zensimbi kanye ne-lubrication bearings ezingenawo amafutha, elayishwa yi-metal matrix futhi igcotshwe ngezinto zokugcoba eziqinile eziklanywe ngokukhethekile.

 

Inezici zomthamo ophezulu wokuthwala, ukumelana nokushayisana, ukumelana nokushisa okuphezulu, ikhono eliqinile lokuzigcoba, njll., ifaneleka kakhulu emithwalweni esindayo, isivinini esiphansi, ukubuyisana noma ukujika kanye nezinye izikhathi okunzima ukuzigcoba nokwenza ifilimu kawoyela, futhi ayikwesabi ukuguguleka kwamanzi kanye nokuguguleka kwamanye ama-asidi. Imikhiqizo isetshenziswe kabanzi emishinini yokuphonsa eqhubekayo yensimbi, imishini yokugoqa, imishini yezimayini, isikhunta, imishini yokuphakamisa, imishini yendwangu, ukukhiqizwa kwamandla omoya, imikhumbi, ama-turbine omusi, ama-turbine amanzi, imishini yokubumba umjovo kanye nemigqa yokukhiqiza imishini. Ukumelana nokuguguleka kuphindwe kabili kunokwe-bushings evamile.

 

Umehluko phakathiamabheringi afakwe uwoyela kanye namabheringi azigcobayo

 

1. I-bearing efakwe uwoyela yenziwe nge-powder yensimbi ehlanganisiwe, enesikhala sesakhiwo esingu-10-40%; I-matrix ye-bearing ezigcobayo ezifakwe ngaphakathi iyi-centrifugal casting; Ubuningi be-substrate buphakeme kakhulu, amandla okubopha aphezulu kunalawo e-bearing efakwe uwoyela, futhi impilo yenkonzo inde kunaleyo ye-bearing efakwe uwoyela.

 

2. Izinto zokugcoba zebheri elifakwe uwoyela uwoyela wokugcoba, futhi ifilimu kawoyela inobukhulu obanele bokuqeda ukuxhumana okuqondile phakathi kwezindawo ezimbili zokungqubuzana. Ngalesi sikhathi, kukhona ukungqubuzana phakathi kwama-molecule oketshezi kuphela, ngakho-ke i-coefficient yokungqubuzana incane kakhulu (f = 0.001~0.008), okunciphisa kakhulu ukungqubuzana nokuguguleka. Izinto zokugcoba ezifakwe kubheri elizigcobayo ziyinto eqinile yokugcoba, engase ibe nomphumela omuhle wokugcoba ngisho nangaphansi kwezimo ezingenawo uwoyela, okungaqinisekisa ukugcobisa okungaphazamiseki nokuqhubekayo, futhi impilo yayo yokugcoba ephumelelayo ihambisana nokuphila kwe-matrix;

 

Uwoyela wokugcoba kubhereyi efakwe uwoyela uyashintshashintsha futhi kulula ukuwulahla, futhi ukulahleka kwefilimu kawoyela wokugcoba kuyasheshiswa ngaphansi kokushisa okuphezulu kanye nokucindezela okuphezulu, futhi umphumela wokugcoba ofanele awukwazi ukutholakala; Esikhwameni sethusi se-graphite, i-lubricant eqinile idluliselwa noma ibuyiselwe emuva endaweni yokungqubuzana ngokungqubuzana, futhi i-lubricant eqinile emgodini noma emseleni idluliselwa noma ibuyiselwe emuva ukuze yakhe ifilimu yokudlulisa eqinile ene-lubricant enhle, ukunamathela okuqinile kanye nokumbozwa okufanayo endaweni yokungqubuzana, okunciphisa kakhulu ukungqubuzana kanye nokuguguleka. Njengoba ukungqubuzana kuqhubeka, i-lubricant eqinile ehlanganisiwe ihlinzekwa njalo endaweni yokungqubuzana, ukuqinisekisa ukugcotshwa okuhle kwe-friction pair ngesikhathi sokusebenza kwesikhathi eside.
