Yintoni umngxuma owenziweyo?
Ishaft yentsimbi eyenziweyoyinxalenye yentsimbi ye-cylindrical eyenziwe ngentsimbi eye yafumana inkqubo yokubumba. Ukubumba kubandakanya ukubumba isinyithi usebenzisa amandla acinezelayo, ngokuqhelekileyo ngokuyifudumeza kwiqondo lobushushu eliphezulu kwaye emva koko ufake uxinzelelo ngokuyibethelela, ukuyicofa okanye ukuyiqengqa. Le nkqubo ikhokelela kwi-shaft eneempawu eziphuculweyo zoomatshini ezifana nokomelela okuphuculweyo, ukuqina, kunye nokumelana nokunxiba xa kuthelekiswa neeshafti ezenziwe ngentsimbi etyhidiweyo okanye ngoomatshini.
I-shafts yensimbi eyenziweyo isetyenziswa ngokubanzi kwizicelo ezahlukeneyo zoshishino apho ukusebenza okuphezulu kunye nokuqina kubalulekile. Iipropathi zabo eziphezulu zoomatshini zibenza balungele ukusetyenziswa kwiindawo ezisingqongileyo, ezinje ngeenjini zeemoto, iisistim ze-aerospace, kunye noomatshini abanzima. Ishafti ekhutshiweyo licandelo elibalulekileyo elisetyenziswa kwimizi-mveliso emininzi, idume ngamandla ayo akhethekileyo, ukuqina, kunye nokuqina. Olu hlobo lwe-shaft lwenziwa ngenkqubo eyaziwa ngokuba yi-forging, apho isinyithi sibunjwa ngokufaka i-high-pressure forces. Kweli nqaku, siza kuphonononga iimpawu eziphambili kunye nenkqubo yokwenziwa kweeshafu ezibunjiweyo ngokweenkcukacha ngakumbi.
Iimpawu zeeShafti zeNtsimbi ezenziweyo
1.Amandla aphezulu:Enye yezona zinto zibalulekileyo eziluncedo kwiishafu zentsimbi ezibunjiweyo ngamandla azo aphezulu. Inkqubo yokuqulunqa ilungelelanisa isakhiwo sengqolowa yensimbi, okwenza izinto eziphathekayo zidibanise kwaye zifanane. Oku kubangela i-shaft ekwazi ukumelana nokudinwa kunye noxinzelelo, ngokukodwa phantsi kwemithwalo ephezulu kunye neemeko ezijikelezayo. Iishafti ezakhiweyo azifane zifumane iziphene ezifana ne-porosity, ezinokuthi zenzeke kwiindawo ezityhidiweyo.
2.Ukuphucula Ukuqina:Iishafu zentsimbi ezenziweyo zibonisa ukomelela okuphuculweyo. Inkqubo yokubumba idala i-homogenous material eneziphene ezimbalwa zangaphakathi, eziphucula ukuxhathisa kwayo kwiimpembelelo, iintanda, kunye nokwaphuka. Oku kwenza i-shafts yentsimbi ekhuniweyo ifaneleke kwizicelo apho icandelo linokuthi libe phantsi kokutshatyalaliswa okanye impembelelo ephezulu.
3.Ukonyuka koKuhlala ixesha elide:Ngenxa yamandla aphezulu kunye nokuqina okunikezelwa ngexesha lenkqubo yokubumba, i-shafts yentsimbi eyenziweyo ihlala ixesha elide phantsi kweemeko zokuguga kunye nokukrazula. Ziyakwazi ukuxhathisa ngokukodwa ukunxiba kwi-friction kwaye ziyakwazi ukugcina ingqibelelo yazo kwiimeko ezinzima, zibenze zilungele umatshini ojikelezayo kunye nezicelo ezinzima.
4.Ukumelana nokuFatigue:Ukumelana nokukhathala kweeshafu zentsimbi ezibunjiweyo yenye yezona zinto zibalulekileyo. Ukuqulunqa kuphelisa i-voids yangaphakathi enokuthi yenze buthathaka inxalenye, ngaloo ndlela inciphisa umngcipheko wokungaphumeleli kwimithwalo ye-cyclic.

5.UKuxhathisa iCorrosion:Ngokuxhomekeke kwi-alloy ethile esetyenzisiweyo kwinkqubo yokubumba (umzekelo, insimbi engenasici, intsimbi ye-alloy), i-shafts yentsimbi ekhuniweyo inokunika ukuxhathisa okugqwesileyo. Iishafu zentsimbi ezenziwe ngezinto ezikwaziyo ukumelana nomhlwa ziyakwazi ukumelana nokuchanabeka kubumanzi, imichiza, kunye neemeko ezirhabaxa zokusingqongileyo, zizenza zilungele ukusetyenziswa kwimizi-mveliso efana neyaselwandle, yokulungisa imichiza namandla.
Iindidi zeeShafti zentsimbi ezibunjiweyo
1.HotIiShafti zentsimbi ezibunjiweyo
Kwi-forging eshushu, intsimbi ifudumala kwiqondo lokushisa ngaphezu kwendawo yayo yokuvuselela, ngokuqhelekileyo phakathi kwe-900 ° C ukuya kwi-1,300 ° C (1,650 ° F ukuya kwi-2,370 ° F), ukuvumela ukubunjwa lula. Le yeyona ndlela ixhaphakileyo yokubumba i-shafts enkulu yensimbi, njengoko iqinisekisa ukuba izinto eziphathekayo zigcina amandla kunye nokunyaniseka ngexesha lokuguqulwa.
