Optimize thread engagement ka dɔgɔya sirili dɛsɛ jɔli baarakɛcogo la .

Jɛkuluw jɔli la, sirilan dɛsɛ man teli ka sɔrɔ fɛnw fanga dɔrɔn fɛ. A ka c’a la, jirisun jɛɲɔgɔnya min bɛ kɛ ka ɲɛ walima min man ɲi, o ye fɛn dogolen ye min bɛ jogindaw lajɔli kɔfɛ, bololanɛgɛw samali-bɔ, ani ɲɔgɔndan dɛsɛ waati tɛmɛnen.

Faamuyali cogo min na jirisunw ka jɛɲɔgɔnya bɛ nɔ bila doni tali la-ani a bɛ se ka kunbɛn cogo min na ni ɲɛfɔli ni sanni kɛcogo ɲuman ye- ye ko kɔrɔba ye jɔli porozɛw la minnu bɛ se ka kɛ lakana ni dannaya ye.

 

 

 

Thread engagement janya de bɛ a jira cogo min na tension ni shear loads bɛ tila-tila bolokɔni ni kɔnɔna jiriw cɛ. Ni jɛɲɔgɔnya tɛ se ka kɛ, doni bɛ sinsin jiri fɔlɔw kan, ka sigida degunw caya kosɛbɛ ani ka jiri tigɛ walima ka kari teliya.

Engineering kɛcogo ɲumanw bɛ caman fɔ ka ɲɛsin engagement janya ma min ka dɔgɔn kosɛbɛ:

O dɛsɛw ka teli ka kɛ hali ni baara bɛ kɛ ni fanga hakɛ caman ye- fanga hakɛ kelen na, o tɛ se ka kɛ sababu ye ka jɛɲɔgɔnya dafabali sara.

 

Ka se ka jirisunw ka baarakɛcogo ɲuman sɔrɔ yɔrɔ la, o ka gɛlɛn ka tɛmɛ dilan jatebɔw kan. Fɛn minnu bɛ kɛ ka caya, olu dɔw ye:
