Ama-powder metallurgy bearings enziwe ngempushana yensimbi nezinye izimpushana zezinto ezilwa nokungqubuzana ezicindezelwe, ezisikiwe, ezibunjiwe futhi zifakwe uwoyela.Banesakhiwo esinezimbotshana.Ngemva kokucwiliswa ngamafutha ashisayo, ama-pores agcwele amafutha okugcoba.Umthelela wokumunca kanye nokushisa okungqubuzanayo kubangela ukuba insimbi namafutha akhule ngokufudumeza, ukukhama uwoyela aphume ezimbotsheni, bese indawo yokungqubuzana isebenza njengokuthambisa.Ngemva kokuphola kokuthwala, amafutha adonswa abuyele ezimbotsheni.

Ama-powder metallurgy bearings abizwa nangokuthi ama-oil-bearing bearings.Lapho ama-bearing aphethe amafutha esesimweni esingasebenzi, i-lubricant igcwalisa izimbotshana zayo.Ngesikhathi sokusebenza, ukujikeleza kwe-shaft kudala ukushisa ngenxa yokungqubuzana, futhi ukwanda okushisayo kwesihlahla esithwalayo kunciphisa ama-pores.Ngakho-ke, i-lubricant iyachichima futhi ingena igebe lokuthwala.Lapho umphini uyeka ukujikeleza, igobolondo elithwele liyaphola, izimbotshana ziyalulama, futhi amafutha okugcoba aphinde amuncwa abuyele ezimbotsheni.Nakuba ama-bearing aphethe uwoyela angase enze ifilimu kawoyela ephelele, ezimweni eziningi, ama-bearings anjalo asesimweni sokungqubuzana okuxubile sefilimu kawoyela engaphelele.

Ama-powder metallurgy bearings anezici zezindleko eziphansi, ukumuncwa kokudlidliza, umsindo ophansi, futhi asikho isidingo sokwengeza uwoyela wokugcoba phakathi namahora amade okusebenza.Zifanele ikakhulukazi ezindaweni zokusebenza okungelula ukuzigcoba noma ukuvumela uwoyela ukuba ungcolile.I-Porosity iyipharamitha ebalulekile yokuthela amafutha.Ama-bearing aphethe uwoyela asebenza ngaphansi kwejubane eliphezulu nomthwalo wokukhanya adinga okuqukethwe okuphezulu kwamafutha kanye ne-porosity ephezulu;ama-bearings aphethe uwoyela asebenza ngaphansi kwejubane eliphansi nomthwalo omkhulu adinga amandla aphezulu kanye ne-porosity ephansi.

Lesi sihloko sasungulwa ekuqaleni kwekhulu lama-20.Isetshenziswe kabanzi ngenxa yezindleko zayo eziphansi zokukhiqiza nokusetshenziswa okulula.Manje isiphenduke ukuthuthukiswa okubalulekile kwemikhiqizo yezimboni ehlukahlukene njengezimoto, izinto zikagesi zasendlini, izinto ezilalelwayo, izinto zasehhovisi, imishini yezolimo, imishini enembayo, njll. Ingxenye eyisisekelo ye.
