Itshintsha njani itekhnoloji yokuzala?

Kule minyaka imbalwa idlulileyo, uyilo lweebheringi luqhubele phambili ngokuphawulekayo luzisa ukusetyenziswa kwezinto ezintsha, ubuchule obuphambili bokuthambisa kunye nohlalutyo oluntsonkothileyo lwekhompyuter..

Iibheringi zisetyenziswa phantse kuzo zonke iintlobo zoomatshini abajikelezayo. Ukusuka kwizixhobo zokhuselo kunye nezixhobo ze-aerospace ukuya kwimigca yemveliso yokutya kunye nesiselo, imfuno yala macandelo iyanda. Okubaluleke kakhulu, iinjineli zoyilo ziya zifuna izisombululo ezincinci, ezikhaphukhaphu kunye nezizinzileyo ukuze zanelise nolona vavanyo lwemeko yokusingqongileyo.

 

Isayensi yezinto

Ukunciphisa ingxabano yindawo ephambili yophando kubavelisi. Izinto ezininzi ezichaphazela ukukhuhlana okunje ngokunyamezelwa komgangatho, ukugqiba komphezulu, ubushushu, umthwalo wokusebenza kunye nesantya. Ukuqhubela phambili okubonakalayo kuye kwenziwa ekuthwaleni intsimbi kule minyaka idlulileyo. Iintsimbi zanamhlanje, ezicocekileyo kakhulu zineentsimbi ezincinci kunye ezincinci ezingezizo ezentsimbi, zinika iibhereyidi zebhola ukuchasana nokudinwa koqhagamshelwano.

 

Ubuchwephesha bokwenza intsimbi yanamhlanje kunye ne-de-gassing buvelisa intsimbi enamanqanaba asezantsi e-oxides, i-sulphides kunye nezinye iigesi ezinyibilikileyo ngelixa iindlela ezingcono zokuqina zivelisa iintsimbi ezinzima kunye nezingagugiyo. Ukuqhubela phambili koomatshini bokuvelisa kwenza abavelisi beebheringi ezichanekileyo bagcine ukunyamezelana okusondeleyo kumacandelo okuthwala kunye nokuvelisa iindawo zoqhagamshelwano eziphuculweyo, zonke ezinciphisa ukungqubana kunye nokuphucula ukulinganiswa kobomi.

 

Iintsimbi ezintsha ze-400-grade stainless (X65Cr13) ziye zaphuhliswa ukuze kuphuculwe amanqanaba engxolo kunye neentsimbi eziphezulu ze-nitrogen zokumelana nokukhula okukhulu. Kwiindawo ezinobungozi kakhulu okanye ubushushu obugqithisileyo, abathengi ngoku banokukhetha kuluhlu lwe-316-grade beebheringi zensimbi ezingenasici, iibheringi ze-ceramic ezigcweleyo okanye iibheringi zeplastiki ezenziwe kwi-acetal resin, i-PEEK, i-PVDF okanye i-PTFE. Njengoko ushicilelo lwe-3D lusetyenziswa ngokubanzi, kwaye ngoko luxabisa ngakumbi, sibona amathuba okwandisa ukuveliswa kwezinto ezigciniweyo ezingabonakaliyo kwiincinci ezincinci, into eya kuba luncedo kwiimfuno zevolumu ephantsi yeebheringi zeengcali.

 

Ukuthambisa

 

Ukuthambisa kusenokuba kuthabathe eyona ngqalelo. Nge-13% yokungaphumeleli kokuthwala okubangelwa yimiba yokuthambisa, ukuthwala i-lubrication yindawo ekhula ngokukhawuleza yophando, exhaswa ngabafundi kunye namashishini ngokufanayo. Ngoku kukho izithambisi ezininzi ezingakumbi enkosi ngenxa yezinto ezininzi: uluhlu olubanzi lweeoyile zokwenziwa ezikumgangatho ophezulu, ukhetho olukhulu lwee-oyile ezityebileyo ezisetyenziselwa ukwenziwa kwegrisi kunye neentlobo ezininzi zezongezo ze-lubricant ukunika, umzekelo, amandla aphezulu omthwalo. okanye ukuxhathisa umhlwa okukhulu. Abathengi banokuchaza iigrisi zengxolo ephantsi ehluzwe kakhulu, igrisi enesantya esiphezulu, izithambisi zamaqondo obushushu agqithisileyo, izithambisi ezingangeni manzi kunye nezinganyangekiyo ngamachiza, izithambisi ezinevacuum ephezulu kunye nezithambisi zegumbi elicocekileyo.

 

Uhlalutyo lwekhompyutha

 

Enye indawo apho ishishini elithwalayo lenze inkqubela phambili kukusetyenziswa kwesoftware yokulinganisa. Ngoku, ukuthwala ukusebenza, ubomi kunye nokuthembeka kunokwandiswa ngaphaya koko kwaphunyezwa kwiminyaka elishumi eyadlulayo ngaphandle kokwenza ilabhoratri ebiza ixesha elibizayo okanye uvavanyo lwasendle. Uhlalutyo oluphezulu, oluhlanganisiweyo lwe-rolling element bearings lunokunika ingqiqo engenakuthelekiswa nanto kwintsebenzo yokuthwala, yenza kube lula ukukhetha ukuthwala kwaye uthintele ukusilela kwangaphambili.

 

Iindlela zobomi bokudinwa okuphezulu kunokuvumela ukuqikelela okuchanekileyo kwezinto kunye noxinzelelo lomdyarho, ukudibana kweembambo, uxinzelelo lomphetho, kunye nokuncitshiswa koqhagamshelwano. Bakwavumela ukuphambuka kwenkqubo epheleleyo, uhlalutyo lomthwalo kunye nohlalutyo lokungalungi kakuhle. Oku kuya kunika iinjineli ulwazi lokuguqula uyilo lokuthwala ukuze lukwazi ukumelana noxinzelelo oluphuma kwisicelo esithile.

 

Enye inzuzo ecacileyo kukuba isofthiwe yokulinganisa inokunciphisa ixesha kunye nezibonelelo ezichithwe kwisigaba sokuvavanya. Oku akukhawulezisi nje kuphela inkqubo yophuhliso kodwa kwakhona kunciphisa iindleko kwinkqubo.

 

Kucacile ukuba uphuhliso lwesayensi yemathiriyeli emitsha kunye nezixhobo ezikumgangatho ophezulu zokulinganisa ziya kubonelela iinjineli ngengqiqo efunekayo ukuyila kunye nokukhetha iibheringi zokusebenza kakuhle kunye nokuqina, njengenxalenye yemodeli yenkqubo yonke. Uphando oluqhubekayo kunye nophuhliso kwezi nkalo ziya kubaluleka ekuqinisekiseni ukuba iibheringi ziyaqhubeka nokutyhala imida kwiminyaka ezayo.
