Amuchina wekucheka magiyachishandiso chekucheka chakasarudzika chinoshandiswa muchitofu chegiya—maitiro ekugadzira anogadzira magiya espur, helical, uye worm. Mucheka (kana kuti "hob") une mazino ekucheka ehelical ayo anogadzira zvishoma nezvishoma profile yegiya kuburikidza nekufamba kwakatenderedzwa nechinhu chebasa.
1. Mhando dzeMagear Hobbing Cutters
Nekugadzirwa
| Rudzi | Tsananguro | Mashandisirwo |
| Chitofu Chemazino Chakatwasuka | Mazino akafanana neakisi; chimiro chiri nyore. | Magiya espur asina kunyatsojeka. |
| Chitofu Chemazino CheHelical | Mazino ari pakona (sehonye); zviri nani kubvisa machipisi. | Magiya emota dzakapinza uye dzakanyatsogadzirwa. |
| Chitofu cheChamfered | Inosanganisira machamfers kusvika kuma deburr gear edges panguva yekucheka. | Kugadzirwa kwemotokari uye kuwanda kwezvinhu. |
| Chitofu chakachekwa | Mavanga akadzika pakati pemazino kuti pave nekubuda kwezvimedu zviri nani kana mavanga akakura. | Magiya makuru emodule (semuenzaniso, kuchera). |
Nezvinhu
Mahobhu eHSS (Simbi Inomhanya Zvikuru)- Inodhura zvishoma, inoshandiswa pakugadzira zvinhu zvakapfava (aruminiyamu, ndarira).
Mahobhi eCarbide– Yakaoma, inogara kwenguva refu, inoshandiswa pakugadzira simbi dzakaomarara & kugadzirwa kwesimbi dzakawanda.
Mahobho Akaputirwa (TiN, TiAlN)- Deredza kukweshana, wedzera hupenyu hwezvishandiso kana zvinhu zvakaoma.
2. Zvikamu Zvikuru zveGear Hob
Module (M) / Diametral Pitch (DP)– Inotsanangura saizi yemazino.
Nhamba Yevanotanga– Kutanga kamwe chete (kwakajairika) vs. kutanga kakawanda (kucheka nekukurumidza).
Angle Yekumanikidza (α)- Kazhinji20°(zvakajairika) kana14.5°(masisitimu ekare).
Dhayamita yekunze- Inokanganisa kuomarara uye kumhanya kwekucheka.
Angle Yekutungamira- Inoenderana nekona yehelix yemagiya ehelical.
3. Kubata magiya kunoshanda sei?
Chishandiso Chebasa & Kutenderera Kwechitofu- Chitofu (cheki) negiya risina chinhu zvinotenderera zvakaenzana.
Kudya kweAxial- Chitofu chinofamba nepakati pegiya risina chinhu kuti chicheke mazino zvishoma nezvishoma.
Kugadzira Kufamba– Mazino emuchitofu anogadzira chimiro chakakodzera che involute.
Mabhenefiti eHobbing
✔ Kugadzirwa kwakanyanya (zvichienzaniswa nekuumbwa kana kugayiwa).
✔ Yakanakiramagiya espur, helical, uye honye.
✔ Kupedzisa pamusoro pechinhu kuri nani pane kugadzira chifukidziro.
4. Mashandisirwo eMagear Hobs
| Maindasitiri | Shandisa Nyaya |
| Mota | Magiya ekufambisa, kusiyana. |
| Muchadenga | Magiya einjini neactuator. |
| Maindasitiri | Mapombi egiya, zvinoderedza simba, michina inorema. |
| Marobhoti | Magiya ekudzora kufamba nemazvo. |
5. Mazano Ekusarudza & Kugadzirisa
Sarudza rudzi rwechitofu chakakodzera(HSS yezvinhu zvakapfava, kabhidhidhi yesimbi yakaoma).
Gadzirisa kumhanya kwekucheka & mwero wekudya(zvinoenderana nezvinhu & module).
Shandisa chinotonhodzakuwedzera hupenyu hwezvishandiso (kunyanya zvema carbide hobs).
Ongorora kana wakapfekwa(mazino akachekwa, makumbo akasakara) kudzivirira mhando yezvigadzirwa zvisina kunaka.
6. Vagadziri vezvitofu zvemagiya vanotungamira
Gleason(Mahobhu chaiwo emagiya espiral bevel & cylindrical)
Zvishandiso zveLMT(Mahobhi eHSS & carbide anoshanda zvakanyanya)
Nyeredzi SU(Mahobhu akagadzirirwa maapplication akasarudzika)
Nachi-Fujikoshi(Japan, mahobhi ane pendi yepamusoro)
