Aiav hobbing cutteryog ib tug tshwj xeeb txiav cuab yeej siv nyob rau hauviav hobbing- cov txheej txheem machining uas tsim cov spur, helical, thiab cab iav. Lub cutter (los yog "hob") muaj helical txiav cov hniav uas nce qib ntawm cov iav profile los ntawm kev sib txuas lus sib txuas nrog lub workpiece.
1. Hom Iav Hobbing Cutters
Los ntawm Tsim
| Hom | Kev piav qhia | Daim ntawv thov |
| Ncaj Hniav Hob | Cov hniav sib npaug rau axis; daim ntawv yooj yim tshaj plaws. | Tsawg-precision spur iav. |
| Helical Hniav Hob | Cov hniav ntawm lub kaum sab xis (zoo li tus cab); zoo dua nti khiav tawm. | Helical & high-precision iav. |
| Chamfered Hob | Xws li chamfers rau deburr iav ntug thaum txiav. | Automotive & loj ntau lawm. |
| Gashed Hob | Sib sib zog nqus gashes ntawm cov hniav kom zoo dua nti clearance nyob rau hauv hnyav txiav. | Loj module iav (piv txwv li, mining). |
Los ntawm Khoom
HSS (High-Speed Steel) Hobs- Economical, siv rau cov ntaub ntawv mos (txhuas, tooj dag).
Carbide Hoob- Nyuaj, lub neej ntev, siv rau hardened steels & high-volume ntau lawm.
Coated Hobs (TiN, TiAlN)- Txo kev sib txhuam, ua kom lub neej ntev ntawm cov khoom siv tawv.
2. Qhov tseem ceeb ntawm lub iav Hob
Module (M) / Diametral Pitch (DP)– Txhais cov hniav loj.
Tus naj npawb pib- Ib zaug pib (nruab nrab) vs. ntau pib (txiav sai dua).
Lub kaum ntse ntse (α)- Feem ntau20 °(common) lub14.5° Nws(cov txheej txheem qub).
Sab nraud txoj kab uas hla- cuam tshuam rigidity & txiav ceev.
Lead Angle- Sib phim lub helix lub kaum sab xis rau helical iav.
3. Gear Hobbing ua haujlwm li cas?
Workpiece & Hob Rotation- Lub hob (cutter) thiab iav dawb tig tig hauv sync.
Axial Pub- Lub hob txav axially hla lub iav khoob kom txiav cov hniav mus ntxiv.
Generating Motion- Lub hob's helical hniav tsim qhov tseeb involute profile.
Qhov zoo ntawm Hobbing
✔ Cov nqi ntau lawm (vs. shaping lossis milling).
✔ Zoo heev rauspur, helical, thiab cab iav.
✔ zoo dua nto tiav dua li broaching.
4. Kev siv ntawm Gear Hobs
| Kev lag luam | Siv Case |
| Automotive | Transmission gears, sib txawv. |
| Aerospace | Cav & actuator iav. |
| Kev lag luam | Iav twj tso kua mis, reducers, hnyav machinery. |
| Robotics | Precision motion control gears. |
5. Cov lus qhia txog kev xaiv & tu
Xaiv hom hob zoo(HSS rau cov ntaub ntawv mos, carbide rau hardened steel).
Optimize txiav ceev & pub tus nqi(nyob ntawm cov khoom & module).
Siv cov dej txiaskom ntev lub cuab yeej (tshwj xeeb tshaj yog rau carbide hobs).
Tshawb xyuas rau hnav(cov hniav chipped, flank hnav) kom tsis txhob muaj cov iav tsis zoo.
