Lefatše la boenjineri ba mechini le lula le batla litharollo tse ncha tsa ho fetisa matla ka nepo, 'me e' ngoe ea liqholotso tse tloaelehileng ke ho fihlella lebelo le nepahetseng.Le ha li-gear tsa bevel esale e le khetho ea ho khetha molemong ona, baenjiniere ba ntse ba tsoela pele ho hlahloba mekhoa e meng ho fihlela litlhoko tse ikhethileng tsa moralo.

Li-Gears tsa Worm:
Lisebelisoa tsa libokofana ka mokhoa o atlehang oa ho fihlella lebelo le nepahetseng.E nang le sekoti se khoele (worm) le lebili le tsamaisanang, tokisetso ena e lumella phetiso ea matla a boreleli.Hangata li-gear tsa Worm li ratoa bakeng sa lits'ebetso moo moralo o kopaneng le phokotso ea lisebelisoa tse phahameng li leng bohlokoa.

Lisebelisoa tsa Helical:
Lisebelisoa tsa Helicals, e tsebahalang ka ts'ebetso ea eona e boreleli le e khutsitseng, e ka hlophisoa hape ho thusa ho khanna ka lehlakoreng le letona.Ka ho hokahanya likere tse peli tsa helical likhutlong tse nepahetseng, baenjiniere ba ka sebelisa mokhoa oa bona oa ho potoloha ho etsa phetoho ea likhato tse 90 ho ea moo.

Miter Gears:
Li-gear tsa miter, joalo ka likere tse betliloeng empa ka lipalo tsa meno tse ts'oanang, fana ka tharollo e otlolohileng bakeng sa ho fumana koloi e lehlakoreng le letona.Ha likere tse peli tsa li-miter mesh perpendicularly, li fetisa motsamao oa ho potoloha ka tsela e nepahetseng.

Chain le Sprocket:
Litabeng tsa indasteri, lits'ebetso tsa ketane le sprocket hangata li sebelisoa ho fihlela li-drive tse nepahetseng.Ka ho hokahanya li-sprockets tse peli ka ketane, baenjiniere ba ka fetisa matla ka mokhoa o atlehileng ka lebelo la 90-degree.Mokhoa ona o thusa haholo ha ho tenyetseha le boiketlo ba tlhokomelo e le lintlha tsa bohlokoa.

Lebanta le Pulley:
Ho tšoana le litsamaiso tsa ketane le sprocket, mabanta le li-pulleys li fana ka tharollo e 'ngoe bakeng sa li-drive tse nepahetseng.Ho sebelisa li-pulleys tse peli le lebanta ho lumella ho fetisa matla ka katleho, haholo-holo maemong ao ho leng bohlokoa ho fokotsa lerata le ts'ebetso e bonolo.

Rack le Pinion:
Le hoja e se koloi e tobileng ea lehlakoreng le letona, tsamaiso ea rack le pinion e lokela ho boleloa.Mochine ona o fetola motsamao oa ho potoloha hore e be motsamao oa mola, o fana ka tharollo e ikhethang bakeng sa lits'ebetso tse itseng moo ho hlokahalang motsamao oa mela ka li-angles tse nepahetseng.

Hore na ba khetha likere tsa liboko, likere tsa helical, li-miter gears, chain le sprocket system, litlhophiso tsa lebanta le pulley, kapa mekhoa ea rack le pinion, baenjiniere ba na le likhetho tse ngata tseo ba ka khethang ho tsona ho latela litlhoko tse ikhethileng tsa lits'ebetso tsa bona.Ha thekenoloji e ntse e tsoela pele, lefapha la boenjineri ba mechini le kanna la bona mekhoa e mecha ea ho fihlela li-drive tse nepahetseng ntle le ho itšetleha ka likere tse tloaelehileng tsa bevel.
