Ajia hobbing ojuomiti wa ni a specialized gige ọpa lo ninuhobbing jia- ilana ṣiṣe ẹrọ ti o ṣe agbejade spur, helical, ati awọn jia alajerun. Awọn ojuomi (tabi "hob") ni o ni helical gige eyin ti o progressively ina awọn jia profaili nipasẹ kan amuṣiṣẹpọ Rotari išipopada pẹlu awọn workpiece.
1. Orisi ti jia Hobbing cutters
Nipa Apẹrẹ
| Iru | Apejuwe | Awọn ohun elo |
| Taara Eyin Hob | Eyin ni afiwe si ipo; rọrun fọọmu. | Kekere-konge spur jia. |
| Helical ehin Hob | Eyin ni igun kan (bi kokoro); dara ni ërún sisilo. | Helical & ga-konge jia. |
| Chamfered Hob | Pẹlu chamfers si deburr jia egbegbe nigba gige. | Automotive & ibi-gbóògì. |
| Gashed Hob | Jin gashes laarin eyin fun dara ni ërún kiliaransi ni eru gige. | Awọn jia module nla (fun apẹẹrẹ, iwakusa). |
Nipa Ohun elo
HSS (High-Speed Steel) Hobs- Ti ọrọ-aje, ti a lo fun awọn ohun elo rirọ (aluminiomu, idẹ).
Carbide Hobs- Lile, igbesi aye gigun, ti a lo fun awọn irin lile ati iṣelọpọ iwọn didun giga.
Awọn Hobs ti a bo (TiN, TiAlN)- Din ija, fa igbesi aye ọpa ni awọn ohun elo alakikanju.
2. Key paramita ti a jia Hob
Modulu (M) / Pitch Diametral (DP)– Awọn asọye ehin iwọn.
Nọmba ti Bẹrẹ– Ibẹrẹ ẹyọkan (wọpọ) la pupọ-ibẹrẹ (gige yiyara).
Igun titẹ (α)– Ojo melo20°(wọpọ) tabi14.5°(agbalagba awọn ọna šiše).
Ita Diamita- Ni ipa lori rigidity & iyara gige.
Igun asiwaju- Ibamu igun hẹlikisi fun awọn jia helical.
3. Bawo ni Gear Hobbing Ṣiṣẹ?
Workpiece & Hob Yiyi- Hob (ojuomi) ati jia òfo yiyi ni amuṣiṣẹpọ.
Ifunni Axial- Hob naa n gbe axially kọja jia òfo lati ge awọn eyin ni ilọsiwaju.
Ti o npese išipopada– Awọn eyin helical hob ṣẹda profaili involute to pe.
Awọn anfani ti Hobbing
✔ Awọn oṣuwọn iṣelọpọ giga (la apẹrẹ tabi milling).
✔ O tayọ funspur, helical, ati alajerun murasilẹ.
✔ Dara dada pari ju broaching.
4. Awọn ohun elo ti Gear Hobs
| Ile-iṣẹ | Lo Ọran |
| Ọkọ ayọkẹlẹ | Awọn ohun elo gbigbe, awọn iyatọ. |
| Ofurufu | Engine & actuator murasilẹ. |
| Ilé iṣẹ́ | Jia bẹtiroli, reducers, eru ẹrọ. |
| Robotik | Konge išipopada Iṣakoso jia. |
5. Aṣayan & Italolobo Itọju
Yan iru hob ti o tọ(HSS fun awọn ohun elo rirọ, carbide fun irin lile).
Ṣe ilọsiwaju iyara gige & oṣuwọn ifunni(da lori ohun elo & module).
Lo coolantlati fa igbesi aye ọpa (paapaa fun awọn hobs carbide).
Ṣayẹwo fun yiya(awọn eyin ti a ti ge, wiwọ flank) lati yago fun didara jia ti ko dara.
6. Asiwaju jia Hob Manufacturers
Gleason(Awọn hobs pipe fun ajija bevel & awọn jia iyipo)
Awọn irinṣẹ LMT(HSS ti o ga julọ & awọn hobs carbide)
Irawo SU(Hobs aṣa fun awọn ohun elo pataki)
