Uthotho lwebhokisi yegiya ye-T ye-spiral bevel eneentlobo ezahlukeneyo ibekwe emgangathweni, yonke imiyinge ye-1:1, 1.5:1, 2:1.2.5:1,3:1.4:1, kunye no-5:1, zezona zokwenyani.Umndilili wokuphumelela ngama-98%.
Kukho kwishafti ye-einput, iishafti ezimbini zokufaka, ishaft ephuma kwicala elinye kunye necala eliphindwe kabini leshaft yokuphuma.
Isixhobo se-Spiral bevel sinokujikeleza kumacala omabini kwaye sihamba kakuhle, ingxolo ephantsi, ukungcangcazela okukhanyayo, ukusebenza okuphezulu.
Ukuba umlinganiselo awukho 1: 1, ukuba isantya segalelo kwi-shaft-extendable shaft, isantya semveliso siya kuncitshiswa;ukuba isantya segalelo kwishaft ephindwe kabini, isantya semveliso siya kuncitshiswa.
