Agia hobbing cutterbụ ngwá ọrụ igbutu pụrụiche eji eme ihegia hobbing- usoro nhazi nke na-emepụta spur, helical, na worm gears. Onye na-egbutu (ma ọ bụ "hob") nwere ezé na-egbu egbu nke na-eji nwayọọ nwayọọ na-emepụta profaịlụ gia site na mmegharị rotary na-arụkọ ọrụ ọnụ.
1. Ụdị nke Gear Hobbing Cutters
Site na imewe
| Ụdị | Nkọwa | Ngwa |
| Hob eze kwụ ọtọ | Ezé yiri axis; kacha mfe ụdị. | Ngwa ngwa spur dị obere. |
| Helical Tooth Hob | Ezé na akụkụ (dị ka ikpuru); mgbawa mgbawa ka mma. | Ngwa ngwa Helical & nke ziri ezi. |
| Chamfered Hob | Na-agụnye chamfers iji deburr gia n'oge ịkpụ. | Automotive & mass mmepụta. |
| Gashed Hob | Ọkpụkpụ dị omimi n'etiti ezé maka mwepu mgbawa ka mma na mbepụ dị arọ. | Nnukwu modul gia (dịka ọmụmaatụ, Ngwuputa). |
Site n'ihe onwunwe
HSS ( Igwe Ọsọ Ọsọ) Hobs- Akụ na ụba, eji maka ihe dị nro (aluminom, brass).
Carbide hobs- Ike siri ike, ndụ ogologo oge, ejiri ígwè siri ike & mmepụta dị elu.
Ihe mkpuchi mkpuchi (TiN, TiAlN)- Belata esemokwu, gbasaa ndụ ngwaọrụ n'ihe siri ike.
2. Akụkụ igodo nke Gear Hob
Modul (M) / Diametral Pitch (DP)– Na-akọwa nha nha nha nha nha nha.
Ọnụọgụ mmalite– Single-mmalite (nkịtị) vs. otutu mmalite (ngwa ngwa ọnwụ).
Akụkụ nrụgide (α)– Na-emekarị20°(nkịtị) ma ọ bụ14.5°(usoro ochie).
Dayameta dị n'èzí- Na-emetụta nkwụsi ike & ịcha ọsọ.
Akụkụ ụzọ- Dakọtara na akụkụ helix maka ngwa ngwa helical.
3. Kedu ka Gear Hobbing si arụ ọrụ?
Arụ ọrụ & Ntụgharị Hob- The hob (cutter) na gia oghere na-atụgharị na mmekọrịta.
Nri Axial- The hob na-akpali axially gafee gia oghere iji bee ezé nke nta nke nta.
Na-emepụta Motion– The hob si helical ezé ike ziri ezi involute profaịlụ.
Uru nke Hobbing
✔ Ọnụ ọgụgụ mmepụta dị elu (vs. ịkpụzi ma ọ bụ igwe igwe).
✔ Ezigbo makaspur, helical, na ikpuru gia.
✔ Mma elu imecha karịa broaching.
4. Ngwa nke Gear Hobs
| Ụlọ ọrụ mmepụta ihe | Jiri Okwu |
| Ụgbọala | Ngwa nnyefe, ihe dị iche iche. |
| Igwe ikuku | Engine & actuator gia. |
| Ụlọ ọrụ mmepụta ihe | Nfuli ngwa ngwa, ndị na-ebelata ihe, igwe dị arọ. |
| Robotics | Ngwa njikwa ngagharị nkenke. |
5. Nhọrọ & Atụmatụ nlekọta
Họrọ ụdị hob ziri ezi(HSS maka ihe dị nro, carbide maka ígwè siri ike).
Hazie ọsọ igbupu & ọnụego ndepụta(dabere na ihe & modul).
Jiri coolantịgbatị ndụ ngwá ọrụ (karịsịa maka hobs carbide).
Nyochaa maka eyi(Ezé gbawara agbawa, uwe n'akụkụ) iji zere ịdị mma gia adịghị mma.
6. Ndị na-emepụta Gear Hob
Gleason(Hobs ziri ezi maka bevel bevel na gia cylindrical)
Ngwa LMT(HSS na hobs carbide na-arụ ọrụ dị elu)
Kpakpando SU(Hobs omenala maka ngwa pụrụ iche)
Nachi-Fujikoshi(Japan, ihe mkpuchi mkpuchi dị elu)
