Najlep\u0161\u00edm sp\u00f4sobom merania uhla tlaku je zoh\u013eadni\u0165 teoretick\u00fd priemer rozstupu ozuben\u00fdch kolies. Ak je priemer rozstupu ozuben\u00fdch kolies mal\u00fd, skuto\u010dn\u00fd uhol bude men\u0161\u00ed. To sp\u00f4sob\u00ed medzeru medzi bokmi ozuben\u00e9ho kolesa. M\u00f4\u017ee to v\u0161ak tie\u017e sp\u00f4sobi\u0165 deform\u00e1ciu ozuben\u00e9ho kolesa, \u010do vedie k neo\u010dak\u00e1van\u00e9mu prev\u00e1dzkov\u00e9mu spr\u00e1vaniu.
Jednou zauj\u00edmavou doty\u010dnicou je rovina rozstupu, pomyseln\u00e1 rovina doty\u010dnica k rozstupov\u00fdm ploch\u00e1m. Rovina rozstupu je rovina kolm\u00e1 na axi\u00e1lnu rovinu prierezu ozuben\u00e9ho kolesa. Zvy\u010dajne sa pou\u017e\u00edva ako referen\u010dn\u00fd bod na v\u00fdpo\u010det uhla prie\u010dneho tlaku.
Pracovn\u00fd tlakov\u00fd uhol je uhol tlakovej \u010diary z\u00e1beru ozuben\u00e9ho kolesa. Tento uhol je rovnak\u00fd ako referen\u010dn\u00fd tlakov\u00fd uhol, ale d\u013a\u017eka kontaktnej \u010diary je skr\u00e1ten\u00e1.
Najlep\u0161\u00edm sp\u00f4sobom v\u00fdpo\u010dtu uhla pracovn\u00e9ho tlaku je pou\u017ei\u0165 tlakov\u00fa \u010diaru z\u00e1beru ozuben\u00e9ho kolesa. To poskytne presnej\u0161iu hodnotu. Skuto\u010dn\u00fd uhol tlakovej \u010diary tie\u017e s\u00favis\u00ed s prevodov\u00fdm pomerom. Tento pomer sa zvy\u010dajne ud\u00e1va ako nomin\u00e1lny pomer uhlov\u00fdch r\u00fdchlost\u00ed.

Posun profilu sa naj\u010dastej\u0161ie sp\u00e1ja s hrotom rezn\u00e9ho n\u00e1stroja. Je to bod, kde evolventn\u00fd profil vystupuje z ozuben\u00e9ho kolesa predt\u00fdm, ako sa hrot za\u010dne zu\u017eova\u0165.

Hrani\u010dn\u00fd bod je bod dotyku medzi evolventn\u00fdm a kore\u0148ov\u00fdm profilom.
Evolventa kru\u017enice je be\u017en\u00fd sp\u00f4sob definovania profilu zuba ozuben\u00e9ho kolesa. Evolventa je dr\u00e1ha, ktor\u00fa bod na priamke sleduje pri odva\u013eovan\u00ed po kru\u017enici.

Celkov\u00fd kontaktn\u00fd pomer definuje priemern\u00fd po\u010det zubov v kontakte v rovine p\u00f4sobenia. Vypo\u010d\u00edta sa vyn\u00e1soben\u00edm prie\u010dneho kontaktn\u00e9ho pomeru pomerom prekrytia. Pomer prekrytia je v\u017edy nenulov\u00fd.
