Enhliziyweni yezitshalo zamandla ama-gearbox adlala indima ebalulekile ekuguquleni amandla emishini abe amandla kagesi. Phakathi kwezinto ezahlukene ezingaphakathi kwala ma-gearbox, amagiya e-bevel futhiamagiya we-helicalbagqame njengabasunguli ababalulekile ekudluliselweni kwamandla.
 Amagiya e-Bevel, ezaziwa ngekhono lazo lokushintsha isiqondiso sokuzungeza, zibalulekile kuma-gearbox ezitshalo zamandla. Idizayini yabo yamazinyo eyingqayizivele ivumela ukudluliswa kwamandla okubushelelezi, okuphumelelayo, ukunciphisa ukudlidliza nomsindo. Lokhu kuzenza zilungele izinhlelo zokusebenza lapho isikhala silinganiselwe futhi ukunemba kubalulekile.
amagiya we-helical, ngakolunye uhlangothi, inikeza inhlanganisela yokusebenza kahle namandla. Iphethini yawo yamazinyo ayi-spiral inciphisa ukungqubuzana nokuguga, inwebe isikhathi sokuphila kuka-gearbox. Ngaphezu kwalokho, amagiya e-helical angadlulisela ama-torque aphezulu futhi asebenze ngesivinini esiphezulu uma kuqhathaniswa namagiya asike ngokuqondile, okuwenza abe yinketho ekhethwayo yezinhlelo zokusebenza ezinzima ezitshalweni zamandla.

Emisha yakamuva ku-bevel kanyeamagiya we-helicaldesign ziye zathuthukisa ukusebenza kwazo. Izinto ezithuthukisiwe, njengama-alloys aphezulu nezinhlanganisela, zifakwe ukuthuthukisa ukuqina nokumelana nokugqokwa. Ukwengeza, amasu okukhiqiza anembayo, okuhlanganisa idizayini esizwa yikhompyutha (CAD) kanye nemishini yekhompyutha elawulwa ngezinombolo (CNC), iqinisekisa ukuthi igiya ngalinye lakhiwe ngendlela enembile.

Lezi zindlela ezintsha azithuthukisanga nje kuphela ukusebenza kahle kokudluliswa kwamandla kodwa futhi zehlise izidingo zokunakekela kanye nezindleko zokusebenza. Ngokuthuthukisa amaphrofayili wezinyo legiya kanye nokunciphisa ukungqubuzana, ama-gearbox esimanje ayakwazi ukusebenza ngokuthula nangokushelela, anciphisa isikhathi sokuphumula futhi athuthukise ukusebenza kwezitshalo kukonke.
Sengiphetha, amagiya e-bevel kanye namagiya we-helical ayizinto ezibalulekile kuma-gearbox ezitshalo zamandla, eziqhuba izinto ezintsha ekudluliseni amandla. Njengoba ubuchwepheshe buqhubeka nokuvela, singalindela ukuthuthuka okukhulu nakakhulu ekwakhiweni kwegiya nokusebenza, okugcine kube nesandla ekuthembekeni nasekusebenzeni kahle kwezinhlelo zethu zokuphehla amandla.
