Kuhlelo lwePlanethi Yegiya, iplanethi yenethiwekhi idlala indima ebalulekile emsebenzini ophelele kanye nokwakhiwa kwe-Gearbox. Ibhokisi legiya leplanethi liqukethe izakhi eziningana, kufaka phakathi aI-Sun Gear,Amagiya weplanethi,i-ring gear,kanye nePlanethi Yesithwali. Nakhu ukuthi kungani umthwali weplanethi kubalulekile:

Ukusekelwa kwamagiya weplanethi:

Umthwali weplanethi usebenza njengesakhiwo sokusekelwa esiphakathi samagiya weplanethi. I-Planet Goes Mesh nge-Sun Gear negiya lendandatho, futhi bazungeza ezungeze i-Sun Gear ngenkathi bevuselela i-axis ephakathi yomthwali weplanethi.

Ukuhanjiswa kwe-torque:
I-torque ekhiqizwa okokufaka (ixhunywe egiya lelanga noma iplanethi yenethiwekhi) idluliselwa kokukhishwayo ngeAmagiya weplanethi. Umthwali weplanethi usiza ukusabalalisa leli qhinga kumagiya weplanethi, okubavumela ukuba bajikeleze futhi bafake isandla ekunciphiseni kwamagiya noma ukushesha.

Ukusatshalaliswa kwemithwalo:

Isithwali seplanethi sisiza ukusabalalisa umthwalo phakathi kweamagiya weplanethi.Lokhu kuhanjiswa kuqinisekisa ukuthi umthwalo kugiya ngalinye ulinganiselayo, uvimbela ukulayishwa ngokweqile kwamagiya ngamanye futhi kuthuthukiswe ukuqina kanye nokwethenjwa kwe-Gearbox.
