U paru s drugim zupčanikom, pri čem je svaki učvršćen na svojem <a href="/wiki/Vratilo" title="Vratilo">vratilu</a>, služi za prijenos rotacijskoga gibanja (<a href="/wiki/Vrtnja" title="Vrtnja">vrtnja</a>) i snage između vratila. Jedan ili više parova zupčanika, s vratilima, ležajevima, kućištem i odgovarajućim priborom, čine <b>zupčanički prijenosnik</b>. Svaki par zupčanika čini jedan stupanj prijenosa, pa zupčanički prijenosi mogu biti jednostupanjski ili višestupanjski. Poput drugih mehaničkih prijenosnika najčešće služe za redukciju brzine vrtnje od pogonskoga na gonjeno vratilo, to jest od pogonskoga na gonjeni <a href="/wiki/Stroj" class="mw-redirect" title="Stroj">stroj</a>. Oblik zupčanika ovisi o međusobnom položaju pogonskog i gonjenoga vratila. Ako su vratila usporedna, prijenos gibanja ostvaruje se valjkastim (cilindričnim) zupčanicima s ravnim, kosim, ili strjelastim zupcima, pri čem veći zupčanik može imati i unutrašnje ozubljenje. U tu skupinu pripadaju i ozubljene letve (zupčanici s beskonačnim promjerom), kojima se rotacijsko gibanje zupčanika pretvara u ravnocrtno gibanje letve ili, rjeđe, obratno. Ako se <a href="/wiki/Os" title="Os">osi</a> vratila međusobno sijeku (najčešće pod pravim kutom), prijenos gibanja ostvaruje se stožastim (koničnim) zupčanicima ili stožnicima. Kada se osi pogonskog i gonjenoga vratila mimoilaze, prijenos se ostvaruje zupčanicima koji teorijski imaju oblik hiperboloida, a aproksimiraju se stožastim zupčanicima (takozvani hipoidni prijenos) ili valjkastim zupčanicima (vijčani prijenos), sa zakrivljenim ili kosim zupcima. Često se primjenjuju i <a href="/wiki/Pu%C5%BEni_prijenos" title="Pužni prijenos">pužni prijenosi</a>, koji se sastoje od pužnoga vijka (zupčanika malog <a href="/wiki/Promjer" title="Promjer">promjera</a> izduženoga u aksijalnom smjeru) i pužnoga kola (zupčanika s kosim zubima s kutom nagiba i bokovima prilagođenima navoju pužnoga vijka). Za pravilan rad zupčanika u zahvatu, točke trenutačnoga dodira zubaca koji se nalaze u zahvatu moraju imati jednake komponente <a href="/wiki/Brzina" title="Brzina">brzina</a> (gledano u smjeru okomice na zajedničku <a href="/wiki/Tangenta" title="Tangenta">tangentu</a> u točki dodira). Tada će <a href="/wiki/Prijenosni_omjer" title="Prijenosni omjer">prijenosni omjer</a> tijekom valjanja jednoga zupca po drugom ostati nepromijenjen, što se postiže posebnim oblikovanjem boka zubaca u obliku krivulje. Zupčanici s takozvanim evolventnim ili kvazievolventnim bokom zubaca (<a href="/wiki/Evolventno_ozubljenje" title="Evolventno ozubljenje">evolventno ozubljenje</a>) čine oko 98 % zupčanika. U prednosti su pred ostalim zupčanicima, jer su neosjetljivi na manje promjene osnoga razmaka (izazvane na primjer pogrješkama u montaži) i izradba im nije tako zahtjevna kao što je to na primjer kod cikloidnog ozubljenja. Većina današnjih zupčanika ima normirana geometrijska svojstva (uglavnom preko takozvanog modula zupčanika), na primjer promjer diobene kružnice (<a href="/wiki/Kru%C5%BEnica" title="Kružnica">kružnica</a> prema kojoj se određuje razmak zubi), broj zuba, korak zuba (razmak među zubima mjeren po diobenoj kružnici), vanjski promjer zupčanika. </p><p>Preteča su današnjih zupčanika primitivni drveni zupčanici, s letvicama ili stupićima (<a href="/wiki/Svornjak" title="Svornjak">svornjacima</a>) umjesto zubaca. Služili su čak i za prijenose gibanja s osima koje se sijeku, a rabili su se već u <a href="/wiki/Drevni_Egipat" title="Drevni Egipat">starom Egiptu</a>, približno između 3000. i 2000. pr. Kr., u uređajima za natapanje.

Plosnatim i klinastim remenom prenosi se snaga i gibanje pomoću veze silom (<a href="/wiki/Trenje" title="Trenje">trenje</a>). Lančani prijenos se upotrebljava tamo gdje je remenski prijenos nemoguć zbog loših prostornih i prijenosnih prilika ili razmaka osi <a href="/wiki/Vratilo" title="Vratilo">vratila</a>. Lančani prijenosi s manjim obuhvatnim kutom i manjim razmakom osi mogu prenositi znatno veće <a href="/wiki/Sila" title="Sila">sile</a> nego remenski prijenos. Općenito im nije potrebno nikakvo predzatezanje, te prema tome manje opterećuju vratila. Lančani prijenosi međutim ne rade elastično i potrebno im je bolje održavanje, jer se moraju podmazivati, a često ih treba zaštititi protiv utjecaja prašine. <a href="/wiki/Lanac" title="Lanac">Lanci</a> i lančanici su znatno skuplji od remena i remenice. Dobri su u gradnji transportnih uređaja, u industriji <a href="/wiki/Motorno_vozilo" title="Motorno vozilo">motornih vozila</a>, za <a href="/wiki/Bicikl" title="Bicikl">bicikle</a> i kod poljoprivrednih <a href="/wiki/Strojevi" title="Strojevi">strojeva</a>. </p><p>Vučni ogranak lančanog prijenosa treba da bude po mogućnosti na gornjoj strani. Kosi položaj prijenosnika je povoljan, dok je okomiti položaj nepovoljan zbog loših zahvata na donjoj lančanici (provjes lanca). Zbog toga su kod vertikalnih lančanih prijenosnika potrebni zatezni lančanici. Okomiti položaj vratila treba po mogućnosti izbjegavati, jer lančane spojnice taru po čeonoj strani lančanika i tako se brzo troše. Budući da se i lanci plastično deformiraju, treba predvidjeti mogućnost naknadnog zatezanja, npr. zatezne lančanike ili zatezna vratila. Kao granica dopuštenog provjesa uzima se oko 2 % razmaka vratila. Lanci su izloženi <a href="/wiki/Vibracije" title="Vibracije">vibracijama</a>, naročito u pogonu s udarima i kod <a href="/wiki/Motor_s_unutarnjim_izgaranjem" title="Motor s unutarnjim izgaranjem">motora s unutarnjim izgaranjem</a>, što izaziva nemiran rad.
