Iiseti zegiya ze-helical ziqhele ukusetyenziswa kwiibhokisi zegiya ze-helical ngenxa yokusebenza kwazo kakuhle kunye nokukwazi ukuphatha imithwalo ephezulu. Ziqulathe iigiya ezimbini nangaphezulu ezinamazinyo e-helical adibana kunye ukuhambisa amandla kunye nentshukumo.
Iigiya ze-Helical zibonelela ngezibonelelo ezinje ngokuncipha kwengxolo kunye nokungcangcazela xa kuthelekiswa neegiya ze-spur, zizenza zilungele usetyenziso apho kubalulekile ukusebenza ngokuzolileyo. Bakwaziwa ngokukwazi kwabo ukuhambisa imithwalo ephezulu kuneegiya ze-spur ezinobungakanani obunokuthelekiswa.
Amazinyo ajikiweyo kwi-oblique kwi-axis gear. Isandla se-helix sichongwe njengasekhohlo okanye ngasekunene. Iigiya ze-helical zesandla sasekunene kunye nesandla sasekhohlo iigiya zehelical zidibana njengeseti, kodwa kufuneka zibe ne-engile ye-helix efanayo.
Iimpawu zeizixhobo ze-helical:
1. Unamandla aphezulu xa kuthelekiswa ne-axhobisa izixhobo 2. Isebenza ngakumbi ekunciphiseni ingxolo kunye nokungcangcazela xa kuthelekiswa nezixhobo ze-spur 3. Iigiya ezikumnatha zivelisa amandla okutyhala kwicala le-axial
Ukusetyenziswa kwezixhobo ze-helical:
1. Amacandelo othumelo 2. Imoto 3. Abanciphisi besantya
Amashishini aphezulu alishumi eTshayina, ixhotyiswe ngabasebenzi abangama-1200, ifumene izinto eziyi-31 zizonke kunye namalungelo awodwa omenzi wechiza ali-9 .Izixhobo zokuvelisa eziphucukileyo, izixhobo zokunyanga ubushushu, izixhobo zokuhlola.
Siza kubonelela ngeengxelo zomgangatho okhuphisanayo kubathengi ngaphambi kokuba yonke into ithunyelwe njengengxelo yobungakanani, isiqinisekiso sezinto eziphathekayo, ingxelo yokuphatha ukushisa, ingxelo echanekileyo kunye nezinye iifayile ezifunekayo zomthengi.
