Amashishini anxulumene nomgubo wesinyithi asetyenziswa ikakhulu kushishino lweemoto, ukuveliswa kwezixhobo, ishishini lesinyithi, i-aerospace, ishishini lomkhosi, izixhobo, izixhobo ze-hardware, izixhobo zombane zasekhaya kunye neminye imimandla yokuvelisa iinxalenye ezisecaleni kunye nophando, imathiriyeli ekrwada enxulumeneyo, imveliso encedisayo, yonke into. Iintlobo zezixhobo zokulungiselela umgubo, ukuvelisa izixhobo zokucoca. Iimveliso ziquka iibheringi, iigiya, izixhobo zokusika i-carbide, iifeyi, iimveliso ezingqubanayo njalo njalo. ezinye izibini zokuqhobosha kufuneka ziveliswe nge-powder metallurgy technology.Kwiminyaka yakutshanje, iinxalenye ze-P/M zemoto ziye zaba yeyona marike inkulu kushishino lweP/M eTshayina.Malunga ne-50% yamalungu e-auto ngamalungu e-P/M.

(1) Usetyenziso :(iimoto, izithuthuthu, oomatshini belaphu, oomatshini bokuthunga bamashishini, izixhobo zombane, izixhobo zehardware.Izixhobo zombane, oomatshini bokwakha, njl.njl.) zonke iintlobo zomgubo wesinyithi (isiseko sentsimbi)

Ngoko.Ukusuka kwimoto, iinxalenye zesithuthuthu kuzo zonke iinxalenye zesinyithi somgubo zibalwa ngomlinganiselo wokunyuka.Ungabona ukuba.Isixhobo se-powder metallurgical ikwindawo yophuhliso olukhawulezayo kuyo yonke i-powder metallurgical parts.If ngokuhambelana neempawu ze-metallurgical. Izixhobo zokwahlula.Izixhobo zezolwakhiwo.Ubunzima obupheleleyo bamacandelo ezakhiwo kuyo yonke intsimbi-esekelwe kwiindawo zikhulu kakhulu kunezinye iindawo.Intlobo ngeentlobo kunye nemveliso yezixhobo zesinyithi zomgubo ziyanda imihla ngemihla, kunye nomda wesicelo sabo. iya isiba banzi.

Oku kungenxa: 1) xa igiya ineegophe ezingaqhelekanga, i-eccentricity, i-radial protrusions okanye imingxuma: xa igiya inemingxuma engaqhelekanga, izitshixo, amacala acaba, i-splines, imingxuma yesikwere, imingxunya ye taper; imingxunya kunye nemingxuma yobunzulu obuhlukeneyo kwicala le-axial direction.Iindlela zesinyithi somgubo zilula ukwenziwa kwaye zifuna ukucutshungulwa ngoomatshini kancinci okanye akukho matshini.Igiya yesinyithi somgubo ngokubanzi kunye nenkqubo yokuvelisa isinyithi somgubo, kufuneka amanyathelo amahlanu kuphela.Okukuthi ukwenza i-sintering yonyango lobushushu ukuthambisa Ioyile yokuntywiliselwa.Umatshini kunye nokuveliswa ngezinto zokugalela kunye nokwenza izinto.Emva kwemoto ngaphandle kwesangqa ngaphakathi kwesangqa esinye okanye ezibini zobuso besiphelo, i-groove yokugaya, i-keyway, i-hobbing gear, i-deburring, unyango lobushushu, ukufudumala kunye ezinye iinkqubo ezilishumi.Ngoko ke, xa i-powder metallurgy method isetyenziselwa ukuvelisa.Ngenxa yephondo labasebenzi, izinto eziphathekayo, ukusebenza kakuhle kwemveliso, ukusetyenziswa kwezixhobo ezincinci, ukonga amandla.Imveliso yeGeariindleko ze-ion ziyancipha kakhulu.2) xa usenza iigiya nge-powder metallurgy method.Izinga lokusetyenziswa kwezinto eziphathekayo lingafikelela ngaphezu kwe-95%.Oku kungenxa yokuba: I-A.Shape enokuthi yenziwe ngokuthe ngqo kwiindawo ezigqityiweyo: B.Nayiphi na inkunkuma yokudibanisa ngaphambi kokucoca .Inokucutywa kwaye isetyenziswe kwakhona.Oku akunakwenzeka xa iigiyeri zenziwe ngezinye iindlela zomatshini.3) Ukuveliswa kwakhona kwezixhobo zesinyithi somgubo womgubo kulungile kakhulu.Ngenxa yomgubo;Isixhobo seTaijin senziwa ngokucinezela ngundo.Phantsi kweemeko eziqhelekileyo zokusetyenziswa, umngundo unokucinezela amashumi amawaka ukuya kumakhulu amawaka ezixhobo ezidityanisiweyo. Zenziwe ngomatshini
