Bevel Gear Spiral Gearing bakeng sa Spiral Gearboxes ke moralo o ikhethileng oa gear o kopanyang sebopeho sa angular sa li-bevel gear le meno a boreleli, a tsoelang pele a spiral gearing. Ho fapana le li-bevel gear tsa setso tse otlolohileng, li-bevel gear tse potolohang li na le meno a kobehileng, a fellang ka ts'ebetso e boreleli, e khutsitseng le bokhoni bo phahameng ba mojaro. Li-gear tsena li sebelisoa hangata li-gearbox tse potolohang, moo li loketseng ho fetisetsa motsamao pakeng tsa li-shaft tse sa tsamaellaneng, hangata ka sekhutlo sa likhato tse 90. Moralo oa meno a potolohang o thusa ho aba mojaro ka ho lekana haholoanyane, o fokotsa ho tsofala le ho ntlafatsa bokhoni. Sena se etsa hore li lokele haholo lits'ebetsong tse kang li-differentials tsa likoloi, mechini ea indasteri le lisebelisoa tse nepahetseng. Li-bevel gear tse potolohang li netefatsa phetiso e ntle ea torque, ts'ebetso e phahameng le ho tšoarella, e leng se etsang hore e be khetho e tsebahalang bakeng sa litsamaiso tsa li-gear tse sebetsang hantle.
Ho kenya gear ea bevel e kobehileng bakeng sa gearmotor reducer, Meno a gear a ne a kobehile, ho nepahala ke ISO8. Thepa: Tšepe ea alloy ea lebokose la 8620. Phepo e futhumetseng: Carburization ho 58-62HRC.
