Akayan yanka kayan haɗikayan aiki ne na musamman na yankewa da ake amfani da shi akayan motsa jiki— wani tsari ne na injin da ke samar da giyar spur, helical, da tsutsa. Mai yankewa (ko "hob") yana da haƙoran yankewa na helical waɗanda ke samar da bayanin gear a hankali ta hanyar motsi mai daidaitawa tare da aikin.
1. Nau'ikan Yankan Hobbing Gear
Ta hanyar Zane
| Nau'i | Bayani | Aikace-aikace |
| Murhun Hakori Madaidaiciya | Hakora suna layi ɗaya da axis; mafi sauƙi tsari. | Giya mai ƙarancin daidaito. |
| Helical Tooth Hob | Haƙora a kusurwa ɗaya (kamar tsutsa); mafi kyawun fitar da guntu. | Giya mai kyau da daidaito. |
| Chamfered Hob | Ya haɗa da ramuka don cire gefunan gear yayin yankewa. | Samar da motoci da yawa. |
| Gashed Hob | Yin zurfin raɓa tsakanin haƙora don samun ingantaccen wurin cire guntu a cikin manyan raunuka. | Manyan kayan aiki na module (misali, hakar ma'adinai). |
Ta hanyar Kayan Aiki
Murhunan HSS (Babban Sauri na Karfe)- Mai tattali, ana amfani da shi don kayan laushi (aluminum, tagulla).
Murhun Carbide– Yana da ƙarfi, tsawon rai, ana amfani da shi don ƙarfe masu tauri da samar da kayayyaki masu yawa.
Murhunan Rufi (TiN, TiAlN)- Rage gogayya, tsawaita rayuwar kayan aiki a cikin kayan aiki masu tauri.
2. Maɓallan Maɓallan Giya
Module (M) / Diameter Pitch (DP)– Yana bayyana girman haƙori.
Adadin Farawa- Farawa ɗaya (na kowa) idan aka kwatanta da farawa da yawa (yankewa da sauri).
Kusurwar Matsi (α)- Yawanci20°(na gama gari) ko14.5°(tsoffin tsarin).
Diamita na Waje- Yana shafar tauri da saurin yankewa.
Kusurwar jagora- Daidaita kusurwar helix don gears na helical.
3. Yaya Kayan Aiki Ke Aiki?
Juyawan Wurin Aiki da Murhu– Murhu (mai yankewa) da kuma gear blank suna juyawa cikin daidaitawa.
Ciyarwar Axial– Murhun yana motsawa a hankali a kan gear ɗin babu komai don yanke haƙora a hankali.
Samar da Motsi– Hakoran helical na murhu suna ƙirƙirar yanayin involute daidai.
Fa'idodin Hobbing
✔ Yawan samarwa (idan aka kwatanta da siffantawa ko niƙa).
✔ Yana da kyau gagiyar spur, helical, da tsutsa.
✔ Ya fi kyau a yi amfani da shi a saman da aka yi da breaching.
4. Amfani da Murhunan Gear
| Masana'antu | Amfani da Shari'a |
| Motoci | Giya mai watsawa, bambance-bambance. |
| sararin samaniya | Giya na injina da na'urar kunnawa. |
| Masana'antu | Famfon giya, na'urorin rage zafi, da manyan injina. |
| Robotics | Gears na sarrafa motsi daidai. |
5. Nasihu kan Zaɓi da Kulawa
Zaɓi nau'in hob ɗin da ya dace(HSS don kayan laushi, carbide don ƙarfe mai tauri).
Inganta saurin yankan & ƙimar ciyarwa(ya dogara da kayan aiki & module).
Yi amfani da ruwan sanyayadon tsawaita rayuwar kayan aiki (musamman ga hobs ɗin carbide).
Duba don lalacewa(haƙoran da suka fashe, lalacewar gefen gefe) don guje wa rashin ingancin kayan aiki.
6. Manyan Masana'antun Kayan Giya
Gleason(Hot ɗin da aka tsara don gears na bevel da silinda)
Kayan Aikin LMT(Masu aikin HSS da hobs ɗin carbide masu inganci)
Tauraro SU(Hotbo na musamman don aikace-aikace na musamman)
Nachi-Fujikoshi(Japan, hobs masu rufi masu inganci)
