Powder metallurgy bearings inogadzirwa nesimbi poda uye mamwe anti-friction zvinhu poda yakatsikirirwa, sintered, shaped and oil-impregnated.Vane porous structure.Mushure mekunyudzwa mumafuta anopisa, pores anozadzwa nemafuta ekuzora.Mhedzisiro yekusveta uye kupisa kunopisa kunoita kuti simbi nemafuta zvikure nekudziisa, kusvina oiri kubva mumapores, uye ipapo friction surface inoita semafuta.Mushure mokunge kutakura kunotonhora, mafuta anoyamwa zvakare mumapores.

Powder metallurgy bearings inonziwo mafuta-bearing bearings.Apo mafuta anotakura mabheji ari mumamiriro asina kushanda, mafuta anozadza pores ayo.Panguva yekushanda, kutenderera kwe shaft kunogadzira kupisa nekuda kwekukakavadzana, uye kuwedzera kwekupisa kwegwenzi rinotakura kunoderedza pores.Naizvozvo, lubricant inopfachukira uye inopinda mugomba rekutakura.Kana shaft ikamira kutenderera, goko rinotakura rinotonhora, maburi anopora, uye mafuta ekuzora anosvetwa zvakare mumapores.Kunyange zvazvo mabheji anotakura mafuta anogona kuumba firimu remafuta rakazara, kazhinji, mabheji akadaro ari mumisanganiswa yakasanganiswa mamiriro emafuta asina kukwana.

Powder metallurgy bearings ane hunhu hwemutengo wakaderera, vibration absorption, yakaderera ruzha, uye hapana chikonzero chekuwedzera mafuta ekuzora panguva refu yekushanda.Vanonyanya kukodzera nzvimbo dzekushanda dzisiri nyore kuisa mafuta kana kubvumira mafuta kuti ave netsvina.Porosity chinhu chakakosha parameter yekutakura mafuta.Oiri-inotakura mabheji anoshanda pasi pekumhanya kukuru uye mutoro wakareruka zvinoda yakakwira oiri yemukati uye yakakwirira porosity;mabheji anotakura mafuta anoshanda pasi pekumhanya kwakaderera uye mutoro wakakura unoda simba rakakura uye kuderera kweporosity.

Ichi chinyorwa chakagadzirwa mukutanga kwezana remakore rechi20.Yakave ichishandiswa zvakanyanya nekuda kwemutengo wayo wakaderera wekugadzira uye kushandiswa kuri nyore.Ikozvino yave budiriro yakakosha yezvakasiyana zvigadzirwa zvemaindasitiri senge mota, midziyo yemumba, maodhiyo emidziyo, midziyo yemuhofisi, michina yekurima, michini chaiyo, nezvimwe. Chikamu chekutanga che.
