Amaqhinga okukhetha izinto ezithwala izinto ezityibilikayo: Uthelekiso lokusebenza kunye nohlalutyo lwesicelo

Kuyilo kunye nokukhethaiibheringi ezityibilikayo, iipropati zezinto ezibonakalayo zimisela ngokuthe ngqo umthamo wazo womthwalo, ubomi benkonzo, kunye nokuzinza kokusebenza. Iimatrices zesinyithi ezahlukeneyo zibonisa umahluko omkhulu kubulukhuni, ukumelana nobushushu, ukuhambelana kokungqubana, kunye nokunciphisa amaxabiso e-PV (uxinzelelo x isantya), zifuna ukuhambelana ngokuchanekileyo ngokusekelwe kwiimeko zokusebenza.

 

Iialloy ze-babbitt ezisekwe kwi-tin (ezifana ne-B83/B88)

 

Zaziwa ngokukwazi kwazo ukunamathela kakuhle kunye nokuhambelana kwazo, zifunxa ngokufanelekileyo ukungcola kwaye zivumelane nokuguquguquka okuncinci kwe-shaft. Zikwanokumelana nokugqwala okugqwesileyo kwaye zifanelekile kwizicelo eziphakathi neziphantsi, ezinomthwalo onzima, kunye nezicelo ezichaphazeleka rhoqo. Nangona kunjalo, amandla azo aphantsi kakhulu kunye nokuthambekela kokuthamba kumaqondo obushushu aphezulu kuthintela ukusetyenziswa kwazo kwiindawo ezinesantya esiphezulu okanye ezinobushushu obuphezulu.

 

I-bronze yetin (udidi oluqhelekileyo: ZCuSn10P1)

 

 

Inamandla aphezulu oomatshini kunye nokumelana nokuguguleka, ifanelekile kwiimfuno eziphezulu, eziqhubekayo. Nangona kunjalo, umphezulu wayo oqinileyo ukhokelela ekusebenzeni kakubi, kufuna ukuchaneka okuphezulu kwejenali, kwaye ithambekele kwiindawo ezishushu ezikufutshane ngexesha lokusebenza kokuqala, nto leyo efuna ukuhlanganiswa okucokisekileyo.

 

Ii-alloys ezidityanisiweyo ezisekwe kwi-aluminium (ezifana ne-AlSn20Cu)

 

Uxinano oluphantsi luvumela uyilo olukhaphukhaphu, ngelixa lukwabonelela ngokuhanjiswa kobushushu obuhle kakhulu kunye nokuzinza kobushushu obuphezulu, okubenza bafaneleke ngokukodwa kwiimeko zokusebenza ezikhawulezayo, ezishushu kakhulu, kunye neemeko eziguquguqukayo. Iimpawu zabo zokuzithambisa ngokwazo zigqwesile kwiibheringi eziphambili zeenjini zeemoto, nto leyo ebenza babe lukhetho oluphambili lwezinto ezisetyenziswa kwiinjini zanamhlanje zokutsha kwangaphakathi.

 

Uthelekiso loMsebenzi:

 

Ngovavanyo lobunzima, uhlalutyo lozinzo lobushushu, kunye novavanyo lwexabiso lomda we-PV, kunokubonwa ukuba nangona i-babbitt alloy ithambile, inika ukuhambelana okuqinileyo; ibronze inika iipropati ezintle zokuthwala umthwalo kodwa ifuna ukulingana ngokuchanekileyo; kwaye ii-aluminium-tin alloys zibonelela ngeenzuzo kwisantya kunye nokunyamezela ubushushu, okwenza ukusebenza kwazo ngokubanzi kufaneke ngakumbi kwiimeko zokusebenza eziguquguqukayo nezintsonkothileyo.

 

Uhlalutyo lweSicelo seTyala:

Kutheni iibheringi ze-aluminium-tin alloy zisetyenziswa kakhulu kwiinjini zezithuthi eziphambili?

Impendulo ikumandla azo agqwesileyo okudinwa kunye nokukwazi kwawo ukucima ubushushu. Ukuqala nokuma rhoqo kwenjini, kunye nokusebenza ngesantya esiphezulu, kubangela ukuguquguquka okukhulu komthwalo wobushushu. Izixhobo ezisekwe kwi-aluminium azipheleli nje ekususeni ubushushu obunokungqubana ngokukhawuleza kodwa zigcina ukuthambisa ngesigaba sazo esithambileyo ngexesha lokuqhekeka kwefilimu yeoyile okwethutyana, zithintela ukuxhuzula kwaye ziphucula kakhulu ukuthembeka.

 

Ukukhethwa kweibhereyithaizixhobo zifuna ulungelelwaniso phakathi kwezinto ezine ezibalulekileyo: amandla okuthwala umthwalo, ukusebenza ngaphakathi, ukumelana nobushushu, kunye nobomi. Akukho "zinto ezisetyenziswa kwihlabathi liphela". Kuphela ngokwenza uvavanyo olucwangcisiweyo olusekelwe kwiimeko zokusebenza zokwenyani apho ibhalansi efanelekileyo phakathi kokusebenza kunye neendleko inokufezekiswa.
