Iibheringi zomgubo zesinyithi zenziwe ngomgubo wesinyithi kunye nezinye izinto ezichasene ne-friction powders ezicinezelweyo, ezifakwe kwi-sintered, ezibunjiweyo kunye ne-oyile efakwe kwi-oyile.Zinesakhiwo se-porous.Emva kokuba ifakwe kwioli eshushu, iipores zizaliswe ngeoli yokuthambisa.Umphumo wokufunxa kunye nokufudumala okuxubeneyo kubangela ukuba isinyithi kunye neoli yandiswe ngokufudumeza, ukukhama ioli kwi-pores, kwaye emva koko i-friction surface isebenza njenge-lubrication.Emva kokuba ukuthwala kupholile, ioli iphinda ifakwe kwi-pores.

Iibheringi ze-powder metallurgy zikwabizwa ngokuba yi-oyile-bearing bearings.Xa iibheringi ezithwele ioli zikwimeko engasebenziyo, i-lubricant igcwalisa iipores zayo.Ngethuba lokusebenza, ukujikeleza kwe-shaft kuvelisa ukushisa ngenxa yokuxhatshazwa, kunye nokwandiswa kwe-thermal ye-bearing bush kunciphisa ama-pores.Ngoko ke, i-lubricant iphuphuma kwaye ingena kwisithuba sokuthwala.Xa ishaft iyeka ukujikeleza, iqokobhe elithweleyo liyaphola, imingxuma iyabuya, ize ioli yokuthambisa ifunxe ibuyele kwimingxuma.Nangona iibheringi ezithwele ioli zinokwenza ifilimu yeoli epheleleyo, kwiimeko ezininzi, iibheringi ezinjalo zikwimeko exubeneyo yefilimu yeoli engaphelelanga.

Iibheringi ze-Metallurgy zePowder zineempawu zexabiso eliphantsi, ukufunxwa kwe-vibration, ingxolo ephantsi, kwaye akukho mfuneko yokongeza ioyile yokuthambisa ngeeyure zokusebenza ezinde.Zifaneleke ngokukodwa kwiindawo zokusebenza ezingelula ukuthambisa okanye ukuvumela ukuba ioli ibe mdaka.I-Porosity yiparameter ebalulekileyo yokuthwala ioli.Iibheringi ezithwala i-oyile ezisebenza phantsi kwesantya esiphezulu kunye nomthwalo wokukhanya zifuna umxholo ophezulu weoli kunye ne-porosity ephezulu;iibheringi zeoli ezisebenza phantsi kwesantya esiphantsi kunye nomthwalo omkhulu zifuna amandla aphezulu kunye ne-porosity ephantsi.

Le ndlela yokuzala yaqanjwa ekuqaleni kwenkulungwane yama-20.Isetyenziswe ngokubanzi ngenxa yexabiso layo eliphantsi lokuvelisa kunye nokusetyenziswa okufanelekileyo.Ngoku iye yaba luphuhliso oluyimfuneko kwiimveliso ezahlukeneyo zemizi-mveliso ezifana neemoto, izixhobo zekhaya, izixhobo zomsindo, izixhobo zeofisi, oomatshini bezolimo, oomatshini bokuchaneka, njl. njl.
