Aisixhobo hobbing cuttersisixhobo sokusika esikhethekileyo esisetyenziswa kwiizixhobo zokuhombisa-inkqubo yomatshini evelisa izixhobo ze-spur, i-helical, kunye ne-worm. Umsiki (okanye "i-hob") unamazinyo okusika i-helical athi ngokuthe ngcembe avelise iprofayile yegiya ngokusebenzisa intshukumo ejikelezayo ehambelanayo nesixhobo sokusebenza.
1. Iintlobo zeGear Hobbing Cutters
NgoYilo
| Uhlobo | Inkcazo | Usetyenziso |
| IsiHobhu sezinyo esiNqo | Amazinyo ahambelana ne-axis; eyona ndlela ilula. | Iigiya ze-spur ezichanekileyo ezisezantsi. |
| I-Helical Izinyo Hob | Amazinyo akwi-engile (njengembungu); ngcono ukukhutshwa kwetshiphu. | Iigiya zeHelical & ezichanekileyo. |
| I-Chamfered Hob | Ibandakanya i-chamfers ukuya kwi-deburr gear edges ngexesha lokusika. | Iimoto kunye nemveliso enkulu. |
| I-Hob yeGashed | Ukuqhekeka okunzulu phakathi kwamazinyo ukuze kulunge ngakumbi ukucocwa kwetshiphu kumanxeba anzima. | Izixhobo zemodyuli ezinkulu (umzekelo, imigodi). |
Ngombandela
IiHobs ze-HSS (IziNsimbi eziPhezulu).– Ezoqoqosho, ezisetyenziselwa izinto ezithambileyo (aluminiyam, ubhedu).
IiHobs zeCarbide-Ubunzima, ubomi obude, obusetyenziselwa iintsimbi eziqinileyo kunye nemveliso ephezulu.
IiHobs ezicatyiswe (TiN, TiAlN)-Nciphisa ingxabano, wandise ubomi besixhobo kwizinto ezinzima.
2. IiParameters eziphambili zeGear Hob
Imodyuli (M) / i-Diametral Pitch (DP)-Ichaza ubungakanani bezinyo.
Inani leziQalo-Ukuqala omnye (okuqhelekileyo) vs. Ukuqala okuninzi (ukusika ngokukhawuleza).
I-engile yoxinzelelo (α)– Ngokwesiqhelo20 °(eqhelekileyo) okanye14.5 °(iinkqubo ezindala).
Ngaphandle Ububanzi-Ichaphazela ubungqongqo kunye nesantya sokusika.
I-engile yokukhokela-Idibanisa i-engile ye-helix yeegiya ze-helical.
3. Isebenza Njani i-Gear Hobbing?
I-Workpiece & Hob Rotation– Isitovu (umsiki) kunye negiya engenanto ijikelezisa kungqamaniso.
Ukutya kwe-Axial– Isitovu sihamba nge-axially ngapha kwesixhobo esingenanto ukusika amazinyo ngokuqhubekayo.
Ukuvelisa intshukumo– Amazinyo e-helical e-hob enza iprofayile echanekileyo.
Izinto eziluncedo kwiHobbing
✔ Amazinga aphezulu emveliso (vs. ukubunjwa okanye ukugaya).
✔ Igqwesile kwii-spur, helical, kunye nezixhobo zeentshulube.
✔ Kungcono ukugqiba umphezulu kunokubhoda.
4. Usetyenziso lweeHobs zeGear
| Ishishini | Sebenzisa Ityala |
| Iimoto | Izixhobo zokuhambisa, ukwahluka. |
| I-Aerospace | Injini kunye nezixhobo zokuvuselela. |
| Imizi-mveliso | Iimpompo zegiya, izinciphisi, oomatshini abanzima. |
| Iirobhothi | Izixhobo zokulawula intshukumo ezichanekileyo. |
5. Iingcebiso zokuKhetha kunye noLondolozo
Khetha uhlobo olufanelekileyo lwesitovu(I-HSS yezinto ezithambileyo, i-carbide yentsimbi eqinile).
Lungiselela isantya sokusika kunye nesantya sokutya(kuxhomekeke kwizinto kunye nemodyuli).
Sebenzisa into yokupholisaukwandisa ubomi besixhobo (ngokukodwa kwi-carbide hobs).
Hlola ukunxiba(amazinyo aqhekeziweyo, ukunxiba kweflank) ukunqanda umgangatho ombi wesixhobo.
6. Abavelisi beGear Hob abaKhokelayo
Gleason(Izihobho ezichanekileyo ze-spiral bevel & cylindrical gears)
Izixhobo ze-LMT(Ukusebenza okuphezulu kwe-HSS kunye ne-carbide hobs)
Inkwenkwezi SU(Iihobs ezilungiselelwe usetyenziso olukhethekileyo)
Nachi-Fujikoshi(eJapan, iihobs ezigqunywe ngomgangatho ophezulu)
