Agear hobbing cutterchishandiso chekucheka chehunyanzvi chinoshandiswa mukatigear hobbing-machining maitiro anoburitsa spur, helical, uye giya rehonye. Iyo yekucheka (kana "hobho") ine mazino ekucheka helical ayo anoramba achigadzira iyo giya mbiri kuburikidza neyakawiriraniswa inotenderera inofamba neiyo workpiece.
1. Mhando dzeGear Hobbing Cutters
By Design
| Type | Tsanangudzo | Applications |
| Nyora Zino Hobho | Mazino anoenderana neaxis; simplest form. | Low-precision spur gears. |
| Helical Zino Hob | Mazino pakona (sehonye); nani chip evacuation. | Helical & yakakwirira-chaiyo magiya. |
| Chamfered Hob | Inosanganisira chamfers kune deburr gear edges panguva yekucheka. | Automotive & mass production. |
| Gashed Hob | Mboro yakadzika pakati pemazino kuitira nani chip clearance mukucheka kunorema. | Hombe module magiya (semuenzaniso, mugodhi). |
Nezvinhu
HSS (High-Speed Steel) Hobs-Economical, inoshandiswa kune zvinyoro zvinhu (aluminium, ndarira).
Carbide Hobs-Kuoma, hupenyu hurefu, hunoshandiswa kune dzakaomeswa simbi & yakakwira-vhoriyamu kugadzirwa.
Coated Hobs (TiN, TiAlN)- Deredza kupokana, wedzera hupenyu hwechishandiso muzvinhu zvakaomarara.
2. Zvikamu zvakakosha zveGear Hob
Module (M) / Diametral Pitch (DP)- Inotsanangura saizi yezino.
Nhamba Yekutanga-Kutanga-kumwe (zvakajairika) vs. multi-kutanga (nekukurumidza kucheka).
Kudzvanya kona (α)– Kazhinji20°(common) kana14.5°(maitiro ekare).
Kunze Diameter- Inokanganisa kuoma & kucheka kumhanya.
Lead angle- Inofananidza iyo helix kona yehelical magiya.
3. Gear Hobbing Inoshanda Sei?
Workpiece & Hob Kutenderera-Iyo hobho (yekucheka) uye giya risina kutenderera rinotenderera mukuwiriranisa.
Axial Feed- Iyo hobho inofamba ichipfuura nepakati pegiya isina kucheka mazino zvishoma nezvishoma.
Kugadzira Motion-Mazino ehelical ehobhu anogadzira iyo chaiyo involute mbiri.
Zvakanakira Hobbing
✔ Mitengo yepamusoro yekugadzira (vs. kuumba kana kugaya).
✔ Yakanaka kunespur, helical, uye giya rehonye.
✔ Kupera kurinani kwepamusoro pane kubhuroka.
4. Zvishandiso zveGear Hobs
| Indasitiri | Shandisa Nyaya |
| Automotive | Transmission gears, differentials. |
| Aerospace | Injini & actuator magiya. |
| Industrial | Mapombi egiya, zvinoderedza, zvinorema muchina. |
| Robotics | Precision inofamba inodzora magiya. |
5. Mazano ekusarudza & Maintenance
Sarudza mhando hobho chaiyo(HSS yezvinhu zvinyoro, carbide yesimbi yakaoma).
Gadzirisa kumhanya kwekucheka & chiyero chekudya(zvinoenderana nezvinhu & module).
Shandisa coolantkuwedzera hupenyu hwezvishandiso (kunyanya kune carbide hobs).
Ongorora kupfeka(mazino akachekwa, flank wear) kudzivirira hurombo hwegiya.
6. Inotungamira Gear Hob Manufacturers
Gleason(Zvakakwana hobho zve spiral bevel & cylindrical gears)
LMT Zvishandiso(Yakakwira-inoshanda HSS & carbide hobs)
Nyeredzi SU(Custom hobs yezvishandiso zvehunyanzvi)
Nachi-Fujikoshi(Japan, hobho dzakashongedzwa dzemhando yepamusoro)
