• Gears bevel straights : u jɔcogo nɔgɔman, u kɛcogo teliya ka dɔgɔn.

• Gears spiral ani hypoid bevel : baara gɛlɛnw, bolifɛnw bolicogo nɔgɔlenw bolifɛnw ka aksidanw ni jɔli masinw kama.

4. Worm Gears (Kɔnɔw ka Gears).

• A bɛ kɛ ka ɲɛsin jirisunw ma minnu tɛ ɲɔgɔn cɛ.

• A bɛ dɔgɔyali hakɛ caman di ani baarakɛcogo lafiyalen; dɔw bɛ u yɛrɛ datugu.

• A bɛ kɛ ascenseurs, hoists ani indexing mechanisms kɔnɔ.

5. Planɛtiw ka girinw

• Compact, torque density ka bon, ani bɔli coaxial.

• Ɲɛ caman bɛ doni tila ɲɔgɔn na, o bɛ kɛ sababu ye ka baara gɛlɛnw kɛ.

• A bɛ kɛ robow la, fanga mɔbili kuraw la, ani servo reducers la.

4. Key Gear Design Paramɛtiriw

• Module (m) – Ɲɛn hakɛ ni doni seko jiralan jɔnjɔn.

• Ɲɛw hakɛ (z) – A bɛ banakisɛfagalanw tali hakɛ dantigɛ :

  i=z1z2 ye

• Pressure Angle (α) – A ka c’a la, a hakɛ dantigɛlen ye 20° ye.

• Helix Angle (β) – A bɛ nɔ bila nɔgɔya ni doni aksidan na.

• Transmission Ratio (i) – A bɛ teliya ni girinya jiginni ɲɛfɔ.

• Center Distance (a) – A bɛ nɔ bila ɲɔgɔnjɛ ni fanga la.

• Face Width (b) – A bɛ nɔ bila doni seko la k’a ɲɛsin a yɛrɛ ma.

5. Gear Accuracy Grades (Jɛkulu ka tiɲɛni hakɛw).

• 0–2 : Ultra-precision, ka ɲɛsin jateminɛ ni minɛn kɔrɔlenw ma.

• 3–5 : Masina minnu bɛ teliya kosɛbɛ minnu bɛ fɛnw sɛgɛsɛgɛ.

• 6–8 : Industriw ka gearbox général, mobili transmissions.

• 9–12 : Teliya dɔgɔman, baara gɛlɛn, sɛnɛko ani minɛnko masinw.

• Kuluba ka fɔcogo fili

• Profil (profil deviation) ka bɔ ɲɔgɔn na

• Plɔmu deviation (plɔmu deviation).

• Radial bolicogo

6. Fɛnw ni funteni furakɛli

Fɛn minnu bɛ kɛ ka caya

• Nɛgɛ minnu bɛ kɛ ni karbon ye : nɛgɛ 45# ye minnu bɛ kɛ girinw ye minnu bɛ baara kɛ ni fɛn bɛɛ ye.

• Nɛgɛw : 40Cr, 42CrMo doni cɛmancɛ–gɛlɛnw kama.

• Nɛgɛ minnu bɛ kɛsu gɛlɛya : 20CrMnTi, 20CrMo ka ɲɛsin girinw ma minnu bɛ baara kɛ kosɛbɛ.

• Nɛgɛ : Nɛgɛ jɛman, nɛgɛ ductile min bɛ kɛ teliya la, a musaka man ca.

• Plastiki : Nilon, POM ka kɛ minɛnw ye minnu bɛ doni nɔgɔman na, minnu mankan man bon.

Funteni furakɛli taabolo

• Quenching and tempering – A bɛ gɛlɛya bɛɛ lajɛlen ɲɛ.

• Surface hardening – Surface hard, core gɛlɛn.

• Carburizing and quenching – Surface gɛlɛya ka bon doni girinmanw na.

• Nitriding – A bɛ fɛn caman tigɛli kɛ, a bɛ se ka sɛgɛn kojugu.

7. Fɛn dilanni taabolo

• Hobbing – A ka ca ni silinda girinw ye.

• Siginiden – A bɛnnen don kɔnɔna ni sen caman-girinw ma.

• Shaving – Soft-finish kɛcogo walasa ka tiɲɛni ɲɛ.

• Grinding – Finifini min bɛ kɛ ka ɲɛ kosɛbɛ girin gɛlɛnw na.

• Forging & extrusion – A ka ca, a fanga ka bon.

8. Tumu ni dɛsɛ cogoyaw

Dɛsɛ minnu bɛ kɛ tuma caman na

• Abrasive wear – A bɛ sɔrɔ tulumafɛnw walima nɔgɔli juguman fɛ.

• Pitting – Sɛgɛn dɛsɛ ka da cyclique contact stress kan.

• Ɲɛw karilen – Doni caya kojugu, a gosili, walima fɛn dɔw tiɲɛni.

• Plastiki bɔgɔbɔgɔli – Teliya dɔgɔyalen, doni girinman cogoyaw la.

• Jatebɔ – Nɛgɛdaga minnu bɛ kɛ ni funteni caman ye, olu bɛ don teliya la bolifɛnw na.

Lubrication Baarakɛcogo

• Aw bɛ dɔ bɔ sɔgɔsɔgɔninjɛ ni sɛgɛn na

• Aw bɛ funteni nɛnɛ ani ka a tiɲɛ

• Aw bɛ aw tanga sɔgɔsɔgɔninjɛ ma

• Aw bɛ mankan dɔgɔya ani ka ɲɛnamaya janya

9. Industriw ka baarakɛcogo

• Mobili : Transmissions, différentiels, timing systems.
