Muɲuli minnu bɛ girin ja kan, olu ye muɲuli ye min bɛ kɛ cogo dafalen na: profil, plɔmu, bore cylindricity, face runout. Fɛn min bɛ a latigɛ n’u bɛ se ka dafa, o ye fɛn hakɛ min bɛ to ka sɔgɔ funteni furakɛli kɔfɛ — wa fɛn tiɲɛnen tɛ ye ka kɔn foro ɲɛ.

Gear Accuracy Ye Accuracy ye funteni furakɛli kɔfɛ

Muɲuli minnu bɛ girinw ni biriki sigilanw kan, olu ɲɛfɔlen don cogo dafalen na: muɲuli profil, muɲuli min bɛ kɛ ni plɔmu ye, bore cylindricity, face runout. Fɛn min bɛ a latigɛ tiɲɛ na n’o bɛ se ka minɛ, o ye allowance hakɛ min bɛ kisi funteni furakɛli ma sɔgɔli kama. Karɔbɔli ni fagali waati, yɔrɔ dɔ bɛ jɔcogo caman tigɛli ni funteni degun sɔrɔ waati kelen na: kogo finmanw bɛ bonya, yɔrɔ belebelebaw bɛ dɔgɔya, yɔrɔ asimɛtiriw bɛ kɔrɔta. A si tɛ ye foro ɲɛfɛ.

Bore min bɛ muɲu kosɛbɛ, o tɛ dilan ni sɔgɔlan ɲuman ye; a bɛ sɔrɔ fɛɛrɛ dɔ fɛ min tun b’a dɔn bore bɛna taa fo yɔrɔ min sani a ka mugu. O la, taabolo dilanni girinw kama, o ye distortion prediction ye ka fara allowance allocation kan. Butigi minnu bɛ se kosɛbɛ, olu bɛ fɛnɲɛnɛmafagalanw jɔ ka kɛɲɛ ni fɛnw ye, kogo ni girinya hakɛ ani doni tali cogoya, o kɔfɛ, u bɛ sumaya-funteni hakɛw musaka bɔ kɔfɛ. Butigi minnu tɛ ni o data ye, olu bɛ se ka allowance caman to dɔrɔn ani ka grinding passes wɛrɛw ta. Musaka bɛ wuli, wa allowance caman bɛ sɔgɔ ka tɛmɛ karɔbɔli kɛsu kɔnɔ ka gɛlɛya jigin.

Tiɲɛni sɔrɔyɔrɔ saba: Fɛnɲɛnɛma, Jateminɛ, Loading

Fɔlɔ ye fɛnw ye. Funteni fila minnu bɛ 20CrMnTi hakɛ kelen na, olu bɛ se ka danfara don u gɛlɛyali bandi bonya la fo ka se ka fɛn caman tigɛli Changer ni kɛmɛsarada la bisaba ye. Mankan kɛcogo ye ka hardenability band report ɲini ka bɔ mansin na ani ka sugandi ka taa band duguma-cɛmancɛ fan fɛ.

Filanan ye jateminɛ ye : kogo janya tɛ kelen ye, keyway offset, dingɛ asymétrique minnu bɛ web kɔnɔ, olu bɛɛ bɛ nɛnɛ bɛnbali lase fagali waati. Olu ka kan ka kɔrɔta jabɔyɔrɔ la — dilancogo min bɛ kɛ ka ɲɛsin fɛn dilanni ma, o bɛ se ka kɛ tuma caman na, fɛn min tɛ kelen ye, o bɛ se ka fɛn dɔ sɛmɛntiya ka kɛ fɛn ye min tɛ simetri ye walima ka taabolo kɔkili dɔ fara a kan. A sabanan ye doni tali ye : fiɲɛbɔlan bɛ fagali jibɔyɔrɔ dantigɛ, nɛnɛ hakɛ bɛ danfara don segi cɛmancɛ ni a da cɛ, wa doni kelen kɔnɔ yɔrɔ minnu bɛ se ka wuli ka taa sira wɛrɛw fɛ.

Grinding Allowance Jatebɔlen don, a tɛ jateminɛ kɛ

Allowance ni distorsion dɔgɔya kojugu tɛ se ka saniya, o bɛ fari nɛrɛma to a sɔgɔlen kɔfɛ. A caya kojugu ani grinding waati ni musaka bɛ wuli ka sɔrɔ ka carburised case farati ka tigɛ. Jatebɔ ɲuman bɛ bɛn bɔgɔbɔgɔli makɔnɔnen ma ka fara stock bɔli kan ka fara lakanafɛn dɔ kan, wa bɔgɔbɔgɔli makɔnɔnen ka kan ka bɔ sumani na, a man kan ka bɔ gafe dɔ la.

Sira waleyali ye taabolo tiɲɛni boli ye : ka tilayɔrɔ tan doni sɛgɛsɛgɛli kelen kɔnɔ, ka hakɛ tilatilali suman ka kɔn o ɲɛ ani o kɔfɛ, ka jiginni cɛmancɛ ni sɛgɛsɛgɛli kɛcogo kɔrɔ sɔrɔ, o kɔfɛ, ka allowance sigi. Sɛnɛ na, aw bɛ misali ta kulu kelen-kelen bɛɛ la ani ka tilali jatebɔ kɛ kɔrɔsili jatebɔsɛbɛn kan; jiginni min bɛ kɛ cɛmancɛ la, o kɔrɔ ye ko foro walima fɛn min yera, o b’a jira ko fɛn caman Changé. Ninnu si tɛ ko kura ye, nka butiki damadɔw de b’a kɛ ka ɲɛ — o ye tigitigi masinw dilanni baara yɔrɔ ye min bɛ kɛ ka kɛɲɛ ni mɔgɔw sago ye, min ka gɛlɛn ka tɛmɛ tɔw bɛɛ kan.

Batch Consistency: Yɔrɔ ɲuman kelen tɛ foyi jira

Dɛsɛ min bɛ kɛ girinw kan, o tɛ yɔrɔ kelen ye min tɛ muɲuli ye, nka o ye batch dispersion ye. Yɔrɔ dɔ bɛ suman ni muɲuli cɛmancɛ ye, o bɛɛ n’a ta, batɛmu dɔ kɔnɔ, a dakun kelen bɛ bɔ — a ka c’a la, o ye funteni bonya, baarakɛminɛnw sɛgɛn ani fɛnw sɔgɔli bɛɛ lajɛlen ye. Lɛrɛ naani kɛlen kɔ ka masin kɛ ka taa a fɛ, spindle funteni bonya bɛ se ka se mikron tan ma, o bɛ se ka muɲuli sira bɛɛ dun.

Kɔlɔsili bɛ ni layini saba ye : sɛbɛn fɔlɔ dafalen, taabolo kɔnɔ misali ta, sɛbɛn laban sɛgɛsɛgɛli ; ka fara funteni sumaya kan sani a ka dilan ani baarakɛminɛn-ɲɛnamaya ɲɛnabɔli ni janya tigɛli ye sanni ka kari. Biriki sigilan minnu sirilen bɛ IT6 la, sumanikɛcogo dankarili yɛrɛ ka kan ka jate: danfara min bɛ jatebɔlan ni baarakɛminɛn cɛ, o bɛ se ka kɛ ka fili mikro kelen kalan milimɛtɛrɛ bi duuru foro kan.

Gear ni Bearing Fit: Yɔrɔ fila, Gɛlɛya kelen

Gear shaft ni a bearing cɛ bɛnkan bɛ latigɛ ɲɔgɔn fɛ: gears muɲuli, bearing kɔnɔna-ring muɲuli, ani u fila bɛɛ lamininen. Misali min bɛ kɛ tuma caman na, o ye ka jiribolo hakɛ dɔrɔn kɔlɔsi ani ka lamini ni a sanfɛla gɛlɛya jateminɛn. O ɲɔgɔndan kelen in na, jirisun min ka lamini man ɲi, o bɛ kɔnɔna bololanɛgɛ sɛmɛntiya ka kɛ fɛn ye min bɛ kɛ fɛn ye min bɛ wele ko ellipse, biriki yɔrɔ janya bɛ Changé, mankan ni funteni jiginni bɛ tugu o kɔ.

O la, nin yɔrɔ suguw ka fisa ni masin ye feerekɛla kelen fɛ, walima a dɔgɔyalenba la datum system kelen kɔnɔ. A tilalen don butiki fila cɛ, a ka ca kosɛbɛ ko u kelen-kelen bɛɛ bɛ tɛmɛ sɛgɛsɛgɛli la ani ka lajɛ kɛ ka dɛsɛ. Ɲininkali tilennen bɛ baara kɛ ka ɲɛ feerekɛlaw ka jateminɛ na: yala gese ni biriki sigilan bɛ kɛ masin na clamping kelen na masin kelen kan wa?

Sɛgɛsɛgɛli: CMM tɛ se ka ɲinw cogoya suman

Gear accuracy tɛ se ka ta CMM kelen fɛ. CMM bɛ bore hakɛ suman, ɲɛda bolicogo ani keyway jɔyɔrɔ, nka profile ni lead tolerances bɛ ɲini ka to ka sɛgɛsɛgɛli kɛ involute sira kan, o kɔrɔ ye ko gear sumanikɛyɔrɔ walima involute sɛgɛsɛgɛlikɛla kɛrɛnkɛrɛnnen. Kuma caman bɛ layidu ta CMM sɛgɛsɛgɛli dafalen na k’a sɔrɔ ɲin sɛbɛn ma sɛgɛsɛgɛ tiɲɛ na abada.

O ye sɔnni sɔsɔli sɔrɔyɔrɔ dɔnta ye : o yɔrɔ bɛ tɛmɛ CMM ka kunnafoniw kan, wa a bɛ sɔgɔsɔgɔ hali bi n’a donna so kɔnɔ. O sababu bɛ se ka kɛ profile crowning ye, helix angle deviation walima accumulated pitch error, wa o si tɛ sigi CMM routine standard kɔnɔ.

Sɔn-ni-sɔn gafe min bɛ se ka baara kɛ, o bɛ kɛ layɛrɛ ye. Barokun fɔlɔ bɛ kunnafoni dafalen sɔrɔ ka bɔ girin sumanikɛyɔrɔ la min bɛ profil, lead, pitch ani radial runout datugu. Sɛnɛfɛnw dilanni boliw bɛ baara kɛ ni sɛgɛsɛgɛli ye min bɛ kɛ ni fila ye i n’a fɔ ɛkran teliyalen, ni waati ni waati sɛgɛsɛgɛli ye ka segin sumanikɛyɔrɔ la. Masina minnu bɛ kɛ fila ye, olu sɔngɔ ka dɔgɔ, wa u teliyalen don fo ka se ka sɛgɛsɛgɛli kɛ kɛmɛsarada la, nka u bɛ fili jɛlen dɔrɔn de jira, wa u tɛ se k’a fɔ ko fɛn jumɛn bɔra, o la, fɛɛrɛ fila ninnu ka kan ka baara kɛ ɲɔgɔn fɛ.

Kɔlɔsili kelen ye sumanikɛlan yɛrɛ kan : girin sumanikɛlan bɛ jateminɛ ni funteni jateminɛ ka tɛmɛ CMM kan, wa degere mugan faralen ɲɔgɔn kan walima ka bɔ kelen na, o ye basigi ye. Ni aw ye jateminɛso ka funteni jatebɔsɛbɛn lajɛ jateminɛ kɛtuma na, o bɛ fɛn caman fɔ aw ye ka tɛmɛ masin tɔgɔ sɛbɛn kan.

Ɲininkali naani bɛ kɛ sannikɛla dɔ fɛ

A fɔlɔ, yala karɔbɔli ni a fagali bɛ kɛ so kɔnɔ wa walima a bɛ kɛ kɛnɛma, wa ni a bɛ kɛ kɛnɛma, yala funteni furakɛlikɛlan bɛ CQI-9 minɛ wa? Filanan, yala sumanikɛlanw bɛ se ka distortion data ma, ni deviation moyenne ani standard deviation ye kuluw ye ka kɛɲɛ ni fɛnw ni kogo janya ye wa? Sabanan, grinding allowance bɛ sigi cogo di, wa yala validation run kɛra wa? Naaninan, batch consistency bɛ sabati cogo di — yala SPC ni baarakɛminɛn-ɲɛnamaya ɲɛnabɔli bɛ yen wa?

Fɛn dilanbaga damadɔw de bɛ o naani bɛɛ jaabi saniya la, nka minnu b’o kɛ, a ka c’a la, olu bɛ kuma fɔ tiɲɛ na, bawo u b’a dɔn k’u tɛna bɔnɛ wari la fɛn tiɲɛnenw kan.
