Fiacail (fiacail)-gach cuid dronnach den ghiar a úsáidtear le haghaidh mogaill. Go ginearálta, socraítear na codanna ardaithe seo go gathach. Tá na fiacla ar na giaranna cúplála i dteagmháil lena chéile, rud a fhágann go mbíonn oibriú meshing leanúnach ar na giaranna.
Cogging-an spás idir dhá fhiacla cóngaracha ar ghiar.

Dromchla deiridh-an plána ingearach d'ais an ghiar nó na péiste ar an ngiar sorcóireach nó ar an bpéist sorcóireach.
Normal surface ─ ─ On a gear, the normal surface refers to the plane perpendicular to the tooth line of the gear.
Ciorcal aguisín-an ciorcal ina bhfuil barr na fiacaile suite.
Ciorcal fréimhe fiacail-an ciorcal ina bhfuil an bun groove suite.
Base circle ─ ─ A circle on which the generating line forming the involute is purely rolling.
Index circle ─ ─ The reference circle for calculating the geometrical dimensions of the gear in the end face. For spur gears, the modulus and pressure angle on the index circle are both standard values.
Dromchla fiacail-an dromchla taobh den fhiacail idir dromchla sorcóireach bharr an fhiacail agus dromchla sorcóireach fhréamh an fhiacail.
Tooth profile ─ ─ The cut line of the tooth surface by a specified curved surface (a plane for cylindrical gears).
Tooth line ─ ─ The intersection line between the tooth surface and the indexing cylindrical surface.
End tooth pitch pt──the length of the indexing arc between the tooth profiles of the two adjacent teeth on the same side.
Modulus m──The quotient obtained by dividing the tooth pitch by the pi, in millimeters.
Diameter P──The reciprocal of the modulus, measured in inches.
Tooth thickness s──the length of the indexing arc between the tooth profiles on both sides of a tooth on the end face.
Groove width e──the length of the indexing arc between the tooth profiles on both sides of a tooth groove on the end face.
Addendum height hɑ──The radial distance between the addendum circle and the index circle.
Tooth root height hf──The radial distance between the index circle and the tooth root circle.
Full tooth height h──The radial distance between the addendum circle and the root circle.
Tooth width b──The size of the gear teeth along the axial direction.
End face pressure angle ɑt── The acute angle between the radial line passing the intersection of the end face tooth profile and the index circle and the tangent line of the tooth profile passing this point.
Raca Caighdeánach: Níl ach toisí an chiorcail bonn, próifíl fiacail, airde fiacail iomlán, airde coróin, agus tiús fiacail go léir racaí a chomhlíonann na sonraíochtaí caighdeánacha fearas spor, agus déantar iad a ghearradh de réir na sonraíochtaí caighdeánacha fearas. Tugtar an raca tagartha air.
Ciorcal Pic caighdeánach: Úsáidtear é chun ciorcal tagartha gach cuid den ghiar a chinneadh. Is é líon na bhfiacla x modulus é
Líne Ghnáthpháirc: Líne pháirce ar leith ar an raca nó ar thiús na fiacail a thomhaistear feadh na líne seo, is é sin leath den pháirc.
Ciorcal Páirce Gníomhaíochta: Nuair a bhuaileann péire spoir le chéile, bíonn tadhlaí ag gach ceann acu chun ciorcal rollta a dhéanamh.
Pic Caighdeánach (Páirc Chaighdeánach): Úsáidtear an pháirc caighdeánach roghnaithe mar an tagarmharc, atá comhionann leis an bpáirc raca tagartha.
Ciorcal Páirce: Tugtar an ciorcal páirce ar an trajectory a fhágtar ar gach giar ag an bpointe teagmhála occlusal ar lárlíne an dá ghiar.
Trastomhas an pháirce: Trastomhas an chiorcail pháirce.
Airde fiacail éifeachtach (Doimhneacht Oibre): airde coróin péire giaranna spor. Ar a dtugtar freisin an airde fiacail oibre.
Aguisín: An difríocht idir an ciorcal aguisín agus ga an chiorcail pháirce.
Backlash: An bhearna idir an dromchla fiacail agus an dromchla fiacail nuair a bhíonn an dá fhiacla ag gabháil.
Imréiteach: Nuair a bhíonn dhá fhiacla ag gabháil, an bhearna idir an ciorcal tip fearas amháin agus bun an fearas eile.
Pointe Páirce: An pointe tadhlaí idir péire giaranna agus an ciorcal tuinairde.
Pic: An t-achar stua de na pointí comhfhreagracha idir dhá fiacla in aice láimhe.
Gnáth-Pháirc: An pháirc a thomhaistear ag an bhfearas ionchuir feadh na líne ingearach céanna de chuid ar leith.
Cóimheas tarchurtha (): An cóimheas idir luas an dá ghiar meshing. Tá luas na giaranna comhréireach inbhéartach le líon na bhfiacla. Go ginearálta, is ionann n1 agus n2 agus luas an dá fhiacla meshing.
