Lisebelisoa tsa lisebelisoa tsa Helical ke karolo ea bohlokoa ka har'a li-gearbox tsa indasteri, tse fanang ka phetisetso ea matla e boreleli le e sebetsang hantle. Ho fapana le li-gear tsa spur, li-gear tsa helical li na le meno a harelaneng a kenang butle-butle, a fana ka ts'ebetso e khutsitseng le ho fokotsa ho thothomela. Sena se li etsa hore li tšoanelehe bakeng sa lits'ebetso tsa lebelo le phahameng, tse boima haholo tse fumanehang liindastering tse joalo ka tlhahiso, tlhahiso ea motlakase le ho sebetsana le thepa.

Meno a nang le mahlakoreng a li-helical gears a etsa hore ho be le sebaka se selelele sa ho kopana pakeng tsa likere, ho aba mojaro ka mokhoa o ts'oanang. Tšobotsi ena e matlafatsa nako e telele 'me e lumella lisebelisoa tsa helical ho sebetsana le torque e phahameng le meroalo ea matla, e li etsa hore li tšoanele li-gearbox tsa indasteri moo ho nepahala le ho tšepahala ho leng bohlokoa. Ho feta moo, moralo oa lisebelisoa tsa helical o fokotsa ho roala, o kenya letsoho bophelong bo bolelele ba ts'ebeletso le ho fokotsa litšenyehelo tsa tlhokomelo.

Li-gearbox tsa indasteri tse nang le likere tsa helical li sebelisoa mecheng e mengata e fapaneng, ho kenyeletsoa lits'ebetso tsa conveyor, li-crusher, li-mixer le mechini e meholo moo phepelo ea motlakase e boreleli e leng bohlokoa bakeng sa ts'ebetso e nepahetseng. Bokhoni ba lisebelisoa tsa helical ho sebetsa ka katleho e phahameng, leha e le ka tlas'a meroalo e boima, e ba etsa khetho e ratoang bakeng sa lits'ebetso tse hlokang indasteri.
