Mea fa'aoga helical fa'aaogaina i le Planetary gearbox helical gear generator helical gearmotor
Ituaiga o le helical gears e lua ituaiga autu: tasi helical gears ma double helical gears. O mea fa'aoga helical e tasi e tipiina nifo i le tulimanu e tasi, e maua ai le gaogao ma le filemu ae fa'atupuina malosi'aga e mana'omia ai le lagolago fa'aopoopo. O mea fa'ailo fa'alua, po'o mea fa'aoga o le herringbone, o lo'o iai ni seti se lua o nifo fa'afeagai. O lenei mamanu e faʻaumatia ai malosiaga faʻamalosi, ofoina atu sili atu paleni ma sili atu le faʻatinoga faʻatasi ai ma le maualuga o le uta gafatia. O ituaiga uma e lua e faʻaleleia ai le faʻaogaina o mea e faʻaogaina ma faʻaitiitia le pisapisao pe a faʻatusatusa i spur gears, ma faʻaogaina ai mo le tele o faʻaoga maualuga ma saʻo.
