Helical Gears: Fɛɛrɛko ɲɛfɔli dafalen

---

Core Design & Paramɛtiriw kunbabaw

• Definition & Basic Form: Ɲɛw bɛ kɛ helicoïde ye, ni helicoid angle (a ka c’a la 15°–30°) bɛ ɲin slan ɲɛfɔ pitch cylinder kan. Gears ye kininbolo (RH) walima numanbolo (LH) ye — meshing parallel pairs mago bɛ helix angles kelenw na nka bolow bɛ ɲɔgɔn kɛrɛfɛ; gese helical crossed (non - parallel shafts) bɛ baara kɛ ni bolo kelen ɲinw ye.

• Paramɛtiriw kɔrɔlenw:

  Paramɛtiriw	ɲɛfɔli
  Angle hélice (β) .	Kɔnɔna min bɛ ɲinw taamasiyɛn ni girin-yɔrɔ cɛ (silinda pitch) .
  Module Normal (mn) ye .	Module sumanlen don ka ɲɛsin ɲin ma; bɛ ɲinw hakɛ ɲɛnabɔ
  Tansiyɔn Angle (α) .	Kɔnɔna min bɛ ɲinw cogoya ni tangent cɛ pitch point (standard 20°) .
  Pitch Diamètre (d) .	d = mn × z / cosβ (z = ɲinw hakɛ) .
  Ladilikan hakɛ (ε) .	A ka bon ka tɛmɛ spur gears kan; bɛ kɛ sababu ye ka doni tilacogo nɔgɔya ɲin caman cɛ

• Meshing Principle : Ɲɛw bɛ don dɔɔni dɔɔni (k’a ta u kun kelen na ka se u bonya bɛɛ ma) ani u bɛ bɔ u la ka ɲɛ, ka u yɛrɛ tanga spur gear dakun nɔ ma - ni u magara ɲɔgɔn na. Parallel shafts bɛ ɲɔgɔn fɛ - bolola girinw de wajibiya walasa ka wuli ka ɲɛ; girinw helikili minnu tigɛra, olu bɛ baara kɛ ni point contact (doni hakɛ dɔgɔyali) ye.

• Axial Thrust (Axial Thrust): Angle helical bɛ axial forces (axial forces) lawuli jirisunba kan, o bɛ thrust - capable bearings (misali la, angular contact ball bearings) walima herringbone gears (mirror - opposite teeth) de wajibiya walasa ka thrust (sɔgɔli) ban.
