Kuphuculo lweshaft ejikeleziswayo kwindawo ebifudula iyisibambi esetyenziswa kwinkqubo yokwenziwa kweemveliso zelatex eziditshiweyo apho ishafti idityaniswe neyunithi edityanisiweyo kwikhonkco lokuhambisa kunye nebhodi eqengqwayo ehlala yangaphambili. umntu owayefudula ephethe uquka iqumrhu eliqengqelekayo elinesiqingatha sokuphumla esisembindini (15) esikwaziyo ukujongana nowangaphambili; i-shaft cross-section shaft ene-d-shaped kwaye ikhuselekile kumzimba we-roller kwaye; ukutshixa kuthetha ukubamba nokutshixa eyokuqala. umzimba oqengqelekayo womnini wangaphambili onesikhokelo sangaphambili esisembindini kwindawo yekhefu kwaye sidibana ngokudibana nokuvuleka komlomo wangaphambili. ishafti enecandelo elinqamlezileyo elimilo engu-d kwelinye icala elikhuselweyo ngokutshixwa lithetha ukuba libunjwe ngokubonakalayo kwi-engile yasekunene kwisikhokelo sangaphambili; esinye isiphelo se-shaft sidityaniswe kwiyunithi yokudibanisa ehambelana nekhonkco lokuhambisa. indlela yokutshixa iyashenxiswa ecaleni komgca ohamba phakathi weshafti ngendlela ecalanye yomnini iseti kwaye ivulwe ngesenzo sentlakohlaza yendlela ecalanye yokukhusela nokutshixa yangaphambili ngokuqinileyo.

Ulungiselelo kunye nendlela yokudibanisa abanini bangaphambili” idiza ilungiselelo kunye nendlela yokuhlanganisa abo babefudula bengabanini-ndawo endaweni yesiqhelo yalowo wayekade ephethe indlela yokwandisa ubuninzi kunye nemveliso kwimveliso yeeglavu. Indlela yokudibanisa abo babefudula bengabanini kwimveliso yeeglavu yopapasho olubhengeziweyo ibandakanya iphini elincanyathiselwe ekupheleni kweshafti nganye exeliweyo esuka kwitsheyini ekhankanyiweyo; iihenjisi ezimbini ezincanyathiselwe kwisikhonkwane ngasinye zithwala isibambi esincamatheleyo, okuthetha ukuba ababini ababefudula babamba babelana ngolwandiso lweshafti enye, apho iperi yeehenjisi kulwandiso lweshafti enye iya kuba nenye phezu kwenye ngexesha lemveliso yeglavu kunye nesibini sabanini bangaphambili. Ekupheleni kweshafti zolwandiso ngalunye oluxeliweyo zahlulwe ngesibini sabanini bangaphambili sithambethelwe ngamadigri angama-90 ukusuka kwindawo yawo yokuqala ngexesha leenkqubo ezifana noshicilelo kunye neglavu. ukuhluba. Nangona kunjalo impumelelo yokuhluthwa kolu lungiselelo lungentla lwabanini bangaphambili ayikafikeleli kwinqanaba elifunekayo. Ngaphezu koko, ngolu lungiselelo lungasentla kukho amathuba okudlula iiglavu ngexesha lenkqubo yokuhlutha, ephinda inciphise ukusebenza kakuhle kwenkqubo yokuvelisa iiglavu.
