Mu dongosolo la ma gearbox a mapulaneti, chonyamulira mapulaneti chimagwira ntchito yofunika kwambiri pa ntchito yonse ndi kapangidwe ka ma gearbox. Ma gearbox a mapulaneti amakhala ndi zigawo zingapo, kuphatikizapozida za dzuwa,zida zapadziko lapansi,zida zoimbira,ndi chonyamulira mapulaneti. Ichi ndichifukwa chake chonyamulira mapulaneti chili chofunikira:

Thandizo la Magiya a Planet:

Chonyamulira cha pulaneti chimagwira ntchito ngati maziko othandizira magiya a pulaneti. Magiya a pulaneti amakhala ndi maukonde ndi zida za dzuwa ndi mphete, ndipo amazungulira giya la dzuwa pomwe akuzunguliranso mozungulira pakati pa chonyamulira cha pulaneti.

Kutumiza kwa Torque:
Mphamvu yopangidwa ndi cholowera (cholumikizidwa ndi giya la dzuwa kapena chonyamulira mapulaneti) imatumizidwa ku chotulutsa kudzera muzida zapadziko lapansiChonyamulira cha planet chimathandiza kugawa mphamvu imeneyi ku magiya a planet, zomwe zimawathandiza kuti azizungulira ndikuthandizira kuchepetsa kapena kukweza liwiro la magiya onse.

Kugawa Katundu:

Chonyamulira cha pulaneti chimathandiza kugawa katundu pakati pazida zapadziko lapansi.Kugawa kumeneku kumaonetsetsa kuti katundu pa giya iliyonse ndi wofanana, zomwe zimathandiza kuti magiya onse azidzaza kwambiri komanso kuti bokosi la gear lizigwira ntchito bwino komanso kuti likhale lolimba.
