Asehahi sa ho hobeke sesebelisoa se khethehileng sa ho itšeha se sebelisoang hoho tsubella ha thepa- ts'ebetso ea mochini e hlahisang lisebelisoa tsa spur, helical le liboko. Sehahi (kapa "hob") se na le meno a sehang a helical a ntseng a tsoela pele ho hlahisa profaele ea gear ka ho tsamaisana le motsamao oa rotary le sesebelisoa sa mosebetsi.
1. Mefuta ea Li-Gear Hobbing Cutters
Ka Moralo
| Mofuta | Tlhaloso | Lisebelisoa |
| Hob ea Leino le Otlolohileng | Meno a bapileng le axis; mokhoa o bonolo ka ho fetisisa. | Likarolo tse tlase tse nepahetseng tsa spur. |
| Helical Tooth Hob | Meno ka lehlakoreng (joaloka seboko); molemo oa ho tlosa chip. | Li-gear tsa Helical le tse phahameng haholo. |
| Chamfered Hob | E kenyelletsa li-chamfer ho li-gear tsa li-gear nakong ea ho seha. | Ho hlahisa likoloi le ka bongata. |
| Gashed Hob | Likhakha tse tebileng pakeng tsa meno bakeng sa ho hloekisoa hantle ha li-chip ha likotoana tse boima. | Lisebelisoa tse kholo tsa module (mohlala, merafo). |
Ka Boitsebiso
HSS (High-Speed Steel) Hobs- Moruo, o sebelisetsoang lisebelisoa tse bonolo (aluminium, koporo).
Li-hobs tsa Carbide- Bophelo bo thata, bo bolelele, bo sebelisetsoang litšepe tse thata le tlhahiso e phahameng haholo.
Li-Coated Hobs (TiN, TiAlN)- Fokotsa likhohlano, eketsa bophelo ba sesebelisoa ka lisebelisoa tse thata.
2. Lintlha tsa bohlokoa tsa Gear Hob
Mojule (M) / Diametral Pitch (DP)- E hlalosa boholo ba meno.
Palo ea Qalo- Qalo e le 'ngoe (e tloaelehileng) khahlano le mefuta e mengata (ho itšeha ka potlako).
Kgatello angle (α)- Ka tloaelo20°(tloaelehileng) kapa14,5°(litsamaiso tsa khale).
Kantle Diameter- E ama ho tiea le lebelo la ho itšeha.
Led Angle- E tsamaisana le angle ea helix bakeng sa likere tsa helical.
3. Gear Hobbing e Sebetsa Joang?
Workpiece & Hob Rotation- Hob (sekhechana) le lisebelisoa tse se nang letho li potoloha ka har'a sync.
Axial Feed- Hob e tsamaea ka axially ho pholletsa le gear e se nang letho ho khaola meno butle-butle.
Ho hlahisa Motion- Meno a helical a hob a theha sebopeho se nepahetseng sa involute.
Melemo ea Hobbing
✔ Litefiso tse phahameng tsa tlhahiso (ha ho bapisoa le sebopeho kapa ho sila).
✔ E ntle bakeng salisebelisoa tsa spur, helical le liboko.
✔ Qeto e ntle ea bokaholimo ho feta ho phunya.
4. Lisebelisoa tsa Gear Hobs
| Indasteri | Sebelisa Taba |
| Tsa makoloi | Lisebelisoa tsa phetisetso, liphapang. |
| Sepakapaka | Lisebelisoa tsa enjine le actuator. |
| Indasteri | Lipompo tsa li-gear, li- reducer, mechine e boima. |
| Liroboto | Likarolo tse nepahetseng tsa ho laola motsamao. |
5. Malebela a Khetho & Tlhokomelo
Khetha mofuta o nepahetseng oa hob(HSS bakeng sa lisebelisoa tse bonolo, carbide bakeng sa tšepe e thata).
Ntlafatsa lebelo la ho itšeha le sekhahla sa phepelo(e ipapisitse le thepa le mojule).
Sebelisa se pholisangho lelefatsa bophelo ba lisebelisoa (haholo-holo bakeng sa li-carbide hobs).
Hlahloba ho apara(meno a qhetsotsoeng, liaparo tsa mahlakoreng) ho qoba boleng bo bobe ba lisebelisoa.
6. Baetsi ba Li-Gear Hob ba ka Sehloohong
Gleason(Li-hobs tse nepahetseng bakeng sa spiral bevel & cylindrical gears)
Lisebelisoa tsa LMT(HSS e sebetsang hantle le li-carbide hobs)
Naleli SU(Li-hobs tsa tloaelo bakeng sa lisebelisoa tse khethehileng)
Nachi-Fujikoshi(Japan, li-hobs tsa boleng bo holimo)
