Ohlelweni lwe-gearbox yeplanethi, ophethe iplanethi udlala indima ebalulekile ekusebenzeni nasekuklanyweni kwebhokisi likagiya.I-gearbox yeplanethi iqukethe izingxenye ezimbalwa, kufaka phakathi aigiya lelanga, amagiya eplanethi, aigiya lendandatho, kanye nomthwali weplanethi.Nakhu ukuthi kungani inkampani yenethiwekhi ibalulekile:

Ukusekelwa Kwezigiya Zeplanethi:

Isithwali seplanethi sisebenza njengesakhiwo esimaphakathi sokusekela amagiya eplanethi.Amagiya eplanethi anezikhala ngawo womabili amagiya elanga kanye negiya lendandatho, futhi azungeza igiya lelanga kuyilapho ezungeza i-eksisi emaphakathi yesithwali seplanethi.

Ukudluliswa kwe-Torque:

I-torque ekhiqizwe okokufaka (exhunywe egiyeni lelanga noma isithwali seplanethi) idluliselwa ekuphumeni ngamagiya eplanethi.Umthwali weplanethi usiza ukusabalalisa le torque kumagiya eplanethi, ukuwavumela ukuthi ajikeleze futhi abambe iqhaza ekwehliseni konke kwegiya noma ukukhuphuka kwesivinini.

Ukusatshalaliswa komthwalo:

Umthwali weplanethi usiza ukusabalalisa umthwalo phakathi kwamagiya eplanethi.Lokhu kusatshalaliswa kuqinisekisa ukuthi umthwalo egiyeni ngalinye uyalingana, kuvimbela ukugcwala ngokweqile kwamagiya ngamanye futhi kukhuthaze ukuqina nokuthembeka kuka-gearbox.
