Mkati mwazomera zamagetsi ma gearbox amatenga gawo lofunikira kwambiri posintha mphamvu zamakina kukhala mphamvu yamagetsi. Zina mwazinthu zosiyanasiyana zomwe zili mkati mwa ma gearbox awa, zida za bevel ndizida za helicaltulukani monga otsogola ofunikira pakufalitsa mphamvu.
 Zida za bevel, omwe amadziwika kuti amatha kusintha njira yozungulira, ndizofunikira kwambiri m'mabokosi opangira magetsi. Mapangidwe awo apadera a mano amalola kusuntha kosalala, kothandiza kwa mphamvu, kuchepetsa kugwedezeka ndi phokoso. Izi zimawapangitsa kukhala abwino kwa mapulogalamu omwe malo ali ochepa komanso kulondola ndikofunikira.
zida za helical, kumbali ina, amapereka kusakaniza kochita bwino ndi mphamvu. Mano awo ozungulira amachepetsa kukangana ndi kuvala, kukulitsa moyo wa gearbox. Kuphatikiza apo, magiya a helical amatha kutumizira ma torque apamwamba ndikugwira ntchito mothamanga kwambiri poyerekeza ndi magiya owongoka, zomwe zimawapangitsa kukhala chisankho chomwe amakonda pakugwiritsa ntchito zolemetsa m'mafakitale amagetsi.

Zatsopano zaposachedwa mu bevel ndizida za helicalkapangidwe kawo kawonjezanso magwiridwe antchito awo. Zida zapamwamba, monga ma aloyi amphamvu kwambiri ndi ma kompositi, zaphatikizidwa kuti zithandizire kulimba komanso kukana kuvala. Kuphatikiza apo, njira zopangira zolondola, kuphatikiza makina othandizidwa ndi makompyuta (CAD) ndi makina oyendetsedwa ndi makompyuta (CNC), zimawonetsetsa kuti zida zilizonse zidapangidwa mwatsatanetsatane.

Zatsopanozi sizinangowonjezera mphamvu zotumizira mphamvu komanso zachepetsanso zofunika pakukonza komanso ndalama zogwirira ntchito. Mwa kukhathamiritsa mbiri ya mano a giya ndikuchepetsa kukangana, ma gearbox amakono amatha kugwira ntchito mwakachetechete komanso bwino, kuchepetsa nthawi yopumira komanso kupititsa patsogolo ntchito ya mbewu yonse.
Pomaliza, magiya a bevel ndi ma helical gear ndi zinthu zofunika kwambiri m'mabokosi opangira magetsi, zomwe zimayendetsa zatsopano pakutumiza mphamvu. Pamene ukadaulo ukupitilirabe kusinthika, titha kuyembekezera kuwongolera kokulirapo pamapangidwe ndi magwiridwe antchito, zomwe zimathandizira kudalirika komanso kuchita bwino kwamagetsi athu opanga magetsi.
