Kuhlelo lwebhokisi lamagiya eplanethi, isithwali seplanethi sidlala indima ebalulekile emsebenzini kanye nomklamo webhokisi lamagiya. Ibhokisi lamagiya leplanethi liqukethe izingxenye eziningana, okuhlanganisaizingubo zelanga,amagiya eplanethi,igiya lendandatho,kanye ne-planet carrier. Nasi isizathu esenza i-planet carrier ibaluleke:

Ukusekelwa kwama-Planet Gears:

Isithwali seplanethi sisebenza njengesakhiwo esiyinhloko sokusekela amagiya eplanethi. Amagiya eplanethi ahlanganiswa kokubili ngegiya lelanga kanye negiya lendandatho, futhi ajikeleza igiya lelanga ngenkathi ejikeleza i-axis ephakathi yesithwali seplanethi.

Ukudluliswa kweTorque:
I-torque ekhiqizwa yi-input (exhunywe kugiya lelanga noma i-planet carrier) idluliselwa ku-output ngokusebenzisa i-amagiya eplanethi. Isithwali seplanethi sisiza ukusabalalisa le torque kumagiya eplanethi, okuwavumela ukuthi ajikeleze futhi afake isandla ekunciphiseni noma ekwandeni kwejubane legiya iyonke.

Ukusatshalaliswa Komthwalo:

Isithwali seplanethi sisiza ukusabalalisa umthwalo phakathiamagiya eplanethi.Lokhu kusatshalaliswa kuqinisekisa ukuthi umthwalo kugiya ngalinye uyalingana, kuvimbela ukugcwala ngokweqile kwamagiya ngamanye futhi kukhuthaza ukuqina nokuthembeka kwegiya.
