- Babban Diamita (D ko d)
Babban diamita ita ce mafi girman diamita na zaren, wanda aka auna shi a ƙugiya don zaren waje da kuma tushen tushen zaren ciki. Da farko yana ƙayyade girman gabaɗayan kusoshi ko dunƙule. Madaidaicin iko na wannan siga yana tabbatar da dacewa daidai da tsayin daka.
- Ƙananan Diamita (D1 ko d1)
Ƙananan diamita shine mafi ƙarancin diamita na zaren, wanda aka auna shi a tushen don zaren waje da kuma a cikin kullun don zaren ciki. Yana tasiri kai tsaye ƙarfin jujjuyawar zaren. Madaidaicin kera ƙananan diamita yana da mahimmanci don cimma daidaitaccen haɗin gwiwa tsakanin zaren mating.
- Pitch Diamita (D2 ko d2)
Diamita na farar yana tsakiyar hanya tsakanin manya da kanana kuma shine inda kaurin zaren yayi daidai da sarari tsakanin zaren. Yana matukar tasiri dacewa tsakanin zaren kuma shine mahimmin siga don auna madaidaicin zaren. Tabbatar da daidaitaccen diamita na farar yana haifar da ingantacciyar kwanciyar hankali.
- Pitch (p) - Ma'auni
Farar yana nufin nisa axial tsakanin igiyoyin zaren da ke kusa. Yana rinjayar saurin taro da daidaiton haɗin kai. Manyan filaye suna sauƙaƙe haɗuwa cikin sauri amma suna iya rage ƙarfin riƙewa, yayin da ƙananan filaye suna ba da ƙuƙumma, ingantattun hanyoyin haɗin da suka dace da aikace-aikacen ɗaukar nauyi.
- Tsare-tsare (α)
Kusurwar zaren ita ce kusurwar da aka haɗa ta bangarorin biyu na bayanin martabar zaren. Kusurwoyi gama gari sun haɗa da 60° don zaren awo da 55° don zaren Standard Whitworth (BSW). Manyan kusurwoyi suna haɓaka juzu'i, haɓaka kaddarorin kulle-kulle, wanda ke da fa'ida don haɗin kai.
- Hannun Hannu (φ)
Kusurwar gefen gefe ita ce kwana tsakanin gefen zaren da layi mai ma'amala da axis. Daban-daban ƙira suna biyan takamaiman buƙatu:
Zaren Triangular: Ya dace da ɗaure-manufa gabaɗaya tare da amintaccen kulle-kulle.
Trapezoidal Threads: Mafi dacewa don aikace-aikace masu ɗaukar nauyi kamar jagororin kayan aikin inji.
Zaren Square: Inganci don watsa wutar lantarki saboda ƙarancin gogayya.
Sawtooth Threads: Ya dace da yanayin ɗorawa unidirectional, kamar a cikin tsarin hydraulic.
- Hanyar Zare
Zaren Hannun Dama: Mafi na kowa, ƙara ƙarfi lokacin da aka juya agogon hannu.
Zaren Hannun Hagu: Ana amfani da shi a cikin aikace-aikace na musamman inda ake son kaddarorin hana sako-sako, kamar a wasu kayan aikin juyawa.
Ƙididdiga gama gari don Pitch da TPI
Zaɓin filin da ya dace ko TPI yana da mahimmanci don tabbatar da kyakkyawan aiki. A ƙasa akwai wasu ƙayyadaddun bayanai da ake yawan amfani da su:

Ma'auni na geometric na zaren suna da mahimmanci ga ayyukansu da aikace-aikacen su. Ta hanyar fahimtar waɗannan sigogi da zabar ƙayyadaddun ƙayyadaddun ƙayyadaddun bayanai, injiniyoyi na iya tabbatar da abin dogaro da ingantattun hanyoyin ɗaure waɗanda aka keɓance da takamaiman aikace-aikace. Ko zabar ma'aunin awo ko na masarauta, daidaitaccen haɗin farar da TPI yana tabbatar da kyakkyawan aiki da tsawon rai a cikin saitunan masana'antu daban-daban.
Na gode don karantawa, idan kuna buƙatar ganin ƙarin abubuwan da muke bayarwa zaku iya bi hanyoyin haɗin yanar gizon da ke ƙasa!
