Indasteri ea tlhahiso ea mechini e hloka mefuta e fapaneng ea li-gear ho etsa mesebetsi e itseng le ho fihlela litlhoko tsa tekheniki. Mefuta e meng e tloaelehileng ea li-gear le mesebetsi ea tsona ke ena:

1. Likere tsa cylindrical: e sebelisoa haholo ho li-bearing ho fana ka torque le matla a phetisetso.
2. Li-gear tsa bevel: e sebediswa maemong ao dibering di sekametseng hanyane ho fihlella phetiso e sebetsang hantle.
3. Likere tsa liboko: e sebelisetsoa ho fana ka karolelano e phahameng ea phetiso, e sebelisoang hangata maemong a lebelo le phahameng a torque e tlase.
4. Li-gear tsa Helical: li sebelisetsoa ho fana ka phetiso e phahameng ea torque le ho rarolla bothata ba lithibelo tsa sebaka sa axial.
5. Li-gear tsa ho fokotsa: li sebelisoa ho fokotsa lebelo la matla a ho khanna ho fihlela taolo e nepahetseng ea lisebelisoa.

Ntle le mesebetsi e boletsoeng ka holimo, li-gear li boetse li hloka ho fihlela litlhoko tse ling tsa tekheniki, tse kang:

1. Litlhoko tsa ho nepahala: ho nepahala ha gear ho na le tšusumetso e kholo ts'ebetsong ea sistimi.
2. Ho hanyetsa ho tsofala: gear e tlameha ho tšoarella ho lekana ts'ebeliso ea nako e telele.
3. Ho tsitsa ha mocheso: gear e tlameha ho ba le botsitso bo botle ba mocheso ho netefatsa phetiso e sebetsang hantle.
4. Boleng ba thepa: lisebelisoa li tlameha ho etsoa ka thepa ea boleng bo holimo ho netefatsa botsitso le ho tšoarella ha tsona.

Tsena ke litlhoko tsa indasteri ea tlhahiso ea mechini bakeng sa li-gear.
