Lisebelisoa tsa Helicalpinion shafte bapala karolo ea bohlokoa ts'ebetsong e nepahetseng ea li-gearbox tsa helical, tse sebelisoang hangata liindastering tse kang likoloi, tlhahiso ea matla le tlhahiso. Li-gear tsa helical li na le meno a sekametseng lehlakoreng, e leng se lumellang phetiso ea matla e bonolo le e khutsitseng ha e bapisoa le likere tse otlolohileng.

The pinion shaft, gear e nyenyane ka har'a gearbox, meshes e nang le lisebelisoa tse kholoanyane kapa sete ea lisebelisoa. Sebopeho sena se fana ka phetisetso e phahameng ea torque ka ho sisinyeha le lerata le fokotsehileng. Moralo oa eona o tiisa kabo e ntle ea mojaro ho feta meno a mangata, e matlafatsang ho tšoarella ha sistimi ea lisebelisoa.

Lisebelisoa tse kang tšepe ea alloy kapa tšepe e thata-thata hangata li sebelisoa bakeng sa li-pinion shafts ho mamella meroalo e boima le ho senyeha. Ho feta moo, li-shafts tsena li etsoa ka mokhoa o nepahetseng oa mochini le kalafo ea mocheso ho netefatsa tlhophiso e nepahetseng le bophelo bo bolelele ba ts'ebeletso.
