Ka pelong ea lifeme tsa motlakase, li-gearbox li bapala karolo ea bohlokoa ho fetoleng matla a mechini hore e be matla a motlakase. Har'a likarolo tse fapaneng tse ka har'a li-gearbox tsena, li-bevel gear lelikere tsa helicalhlahella e le baqapi ba bohlokoa phetisong ea motlakase.
 Li-gear tsa bevel, tse tsebahalang ka bokhoni ba tsona ba ho fetola tsela eo li potolohang ka eona, li bohlokoa haholo li-gearbox tsa lifeme tsa motlakase. Moralo oa tsona o ikhethang oa meno o lumella phetiso ea motlakase e boreleli le e sebetsang hantle, e fokotsang ho thothomela le lerata. Sena se li etsa hore li be ntle bakeng sa lits'ebetso moo sebaka se fokolang 'me ho nepahala ho le bohlokoa.
likere tsa helicalKa lehlakoreng le leng, li fana ka motsoako oa bokhoni le matla. Mokhoa oa meno a tsona a potolohang o fokotsa khohlano le ho tsofala, o atolosa nako ea bophelo ba lebokose la li-gear. Ho feta moo, li-gear tse helical li ka fetisa li-torque tse phahameng 'me tsa sebetsa ka lebelo le phahameng ha li bapisoa le li-gear tse sehiloeng ka ho otloloha, e leng se etsang hore e be khetho e ratoang bakeng sa lits'ebetso tse boima lifekthering tsa motlakase.

Mekhoa e mecha ea morao tjena ea bevel lelikere tsa helicalMoralo o ntlafalitse tshebetso ya tsona haholo. Disebediswa tse tswetseng pele, tse kang di-alloy tse matla le di-composite, di kentswe ho ntlafatsa ho tshwarella le ho hanyetsa ho tsofala. Ho feta moo, mekgwa ya tlhahiso e nepahetseng, ho kenyeletswa moralo o thuswang ke khomphutha (CAD) le machining e laolwang ke dipalo tsa khomphutha (CNC), di netefatsa hore sesebediswa se seng le se seng se entswe ho latela ditaelo tse nepahetseng.

Mekhoa ena e mecha ha ea ntlafatsa feela katleho ea phetiso ea motlakase empa hape e fokolitse litlhoko tsa tlhokomelo le litšenyehelo tsa ts'ebetso. Ka ho ntlafatsa liprofaele tsa meno a gear le ho fokotsa khohlano, li-gearbox tsa sejoale-joale li khona ho sebetsa ka khutso le ka thelelo, li fokotsa nako ea ho se sebetse le ho ntlafatsa ts'ebetso ea fektheri ka kakaretso.
Qetellong, li-gear tsa bevel le li-gear tsa helical ke likarolo tsa bohlokoa ka ho fetisisa li-gear tsa motlakase, tse khannang boqapi phetisong ea motlakase. Ha theknoloji e ntse e tsoela pele ho fetoha, re ka lebella lintlafatso tse kholo le ho feta moralong le ts'ebetsong ea li-gear, tse tla qetella li tlatsetsa botšepehing le katlehong ea litsamaiso tsa rona tsa tlhahiso ea motlakase.
