Ithonya le-curvature radius yesigaba se-convex ne-concave kusihambisi sebhande

I-Arch phakathi kwesigaba esiphambanweni sebhande le-convex

     Ingxenye ye-convex yesithwala sebhande ivame ukwenzeka maphakathi kwesigaba sebhande esiqonde entengweni, yomibili iphume phakathi. Futhi ibhande lizokwehliswa, futhi nezinga lokulimala lebhande lizokhuthazwa ngemuva kokuthi lisongwe libe yisikhawu sesigubhu sokuqondisa kabusha noma isigubhu sokushayela. Isizathu esiyinhloko sokugoqa nokwephula ukuthi inani lokungezwani lobude beyunithi phakathi nangaphandle kwengxenye yesiphambano sebhande lihluke kakhulu, ukuze ibhande lishelele phakathi ukuze lenze ukugoqa noma ukuphuka. Umehluko wenani lokungezwani ngobude beyunithi ngalinye uhlobene nobubanzi be-curvature yengxenye ye-convex ne-groove Angle ye-roller. I-Angle ye-groove ikhudlwana, i-radius engxenyeni ye-convex encane, futhi ukuqina nokuqhekeka kunzima kakhulu. Lapho i-groove Angle yesithwala sebhande ingaphezu kwama-degree angama-40, noma esigabeni esiqondile sekhanda lokuhambisa ibhande noma umsila we-roller groove I-Angle change interval ingenzeka i-arch nesaphulelo, ngalesi sikhathi kufanele inciphise i-groove engela noma yenze ubude be ushintsho isikhawu, ukuze inkatho ibhande engela inguquko slow. Okokuhambisa ibhande le-convex, irediyamu egobile yesigaba se-convex kufanele inyuswe ngangokunokwenzeka futhi i-groove Angle ye-roller kufanele yehliswe ngaphansi kwesisekelo sokwanelisa amandla wokuhambisa.

Ibhande esigabeni se-convex liboshwe phakathi kwe-flat flat ne-oblique roll

Isimo sokuthi ibhande linamathele phakathi kwe-roller eyisicaba ne-roller ethambekele ekusetheni i-roller set evame ukwenzeka kumishini yokuthutha ngobuningi. Njengomshini wokulayisha, isitaki se-stacker. Lesi senzakalo senzeka kalula lapho isikhundla sempande ye-cantilever yalolu hlobo lwemishini singaphansi kwe-cantilever. Ngalesi sikhathi, kubuye kufane nesigaba se-convex sebhande. Ngenxa yomkhawulo wesikhundla sejometri nosayizi, kunzima ukuhlangabezana nosayizi odingwa yi-curvature radius yesigaba se-convex yenguquko. Lapho ibhande litholakala empandeni ye-cantilever, uma isigaba se-convex sakhiwa kuphela ngeqoqo elilodwa noma amabili ama-idlers, ibhande lizonamathela phakathi kwe-flat flat kanye ne-oblique roll ye-idlers. Isixazululo ukuguqula isigaba se-convex esakhiwe iqembu lokuqala elilodwa noma amabili ama-idlers abe ngamaqembu amane noma amahlanu noma amaqembu angaphezu kwalokho.

Isigaba se-concave siyaphuma futhi siphambukiswa ngumoya lapho siqala

Uma kungekho okuthathwayo kusihambisi sebhande ekuqaleni kwebhande, ibhande lizoshaya esigabeni se-concave sesikhawu, lapho umoya uzoshaya ibhande, ngakho-ke, kungcono ukufaka isondo lebhande lengcindezi esigabeni se-concave yokuhambisa ibhande ukugwema ukuqhuma kwebhande noma ukushaywa umoya.
