Lisebelisoa tsa Helical e sebelisoang ho Planetary gearbox helical gear jenereithara ea helical gearmotor
Mefuta ea likere tsa helical mefuta e 'meli ea mantlha: likere tse le 'ngoe tsa helical le likere tse habeli tsa helical. Li-gear tse le 'ngoe tsa helical li na le meno a sehiloeng ka lehlakoreng le le leng, li fana ka ts'ebetso e boreleli le e khutsitseng empa li hlahisa matla a axial a hlokang tšehetso e eketsehileng ea ho jara. Li-gear tse peli tsa helical, kapa herringbone gear, li na le lihlopha tse peli tsa meno a mabeli a nang le li-angles tse hanyetsanang. Moralo ona o hlakola matla a axial, o fana ka ts'ebetso e leka-lekaneng le e khutsitseng ka boima bo phahameng ba mojaro. Mefuta ena ka bobeli e ntlafatsa meshing ea lisebelisoa le ho fokotsa lerata ha e bapisoa le likere tsa spur, li etsa hore li tšoanelehe bakeng sa lits'ebetso tse fapaneng tsa torque e phahameng le tse nepahetseng.
