Iizixhobo zeentshulube isinciphisi sisixhobo sokuhambisa amandla esisebenzisa isiguquli sesantya segiya ukuthoba inani leenguqu zemoto (motor) ukuya kwinani elifunekayo leenguqu kunye nokufumana itorque enkulu. ukuhambisa amandla kunye nentshukumo, uluhlu lwesicelo sokunciphisa lubanzi kakhulu. Umkhondo wayo unokubonwa kwinkqubo yokuhanjiswa kwazo zonke iintlobo zoomatshini, ukusuka kwiinqanawa, iimoto, iilocomotives, oomatshini abanzima bokwakha, umatshini wokulungisa kunye nezixhobo zokuvelisa ezizenzekelayo ezisetyenziswa kumashishini oomatshini, ukuya kwizinto eziqhelekileyo zasekhaya kubomi bemihla ngemihla. , iiwotshi, njl. Ukusetyenziswa kokunciphisa kunokubonwa ukusuka ekuhanjisweni kwamandla amakhulu ukuhanjiswa kwemithwalo encinci kunye ne-angle echanekileyo. Kwizicelo zoshishino, umnciphisi unemisebenzi yokunciphisa kunye nokunyuka kwe-torque. Ke ngoko, isetyenziswa kakhulu kwisantya kunye nezixhobo zokuguqula itorque.

Ukuze kuphuculwe ukusebenza kakuhle kwesinciphisi segiya leentshulube, iintsimbi ezingenayo intsimbi zihlala zisetyenziswa njengegiya yeentshulube kunye nentsimbi eqinileyo njengeshaft yeentshulube. Ngenxa yokuba i-sliding friction drive, ngexesha lokusebenza, iya kuvelisa ukushisa okuphezulu, okwenza iindawo zokunciphisa kunye nesitywina. Kukho umahluko ekwandiseni i-thermal phakathi kwabo, okubangela umsantsa phakathi kwendawo nganye yokukhwelana, kwaye i-oyile iba yincinci ngenxa yokwanda kweqondo lokushisa, ekulula ukubangela ukuvuza. Kukho izizathu ezine eziphambili, esinye sesokuba ukuhambelana kwemathiriyeli kunengqiqo, enye ngumgangatho womphezulu we-meshing surface friction, eyesithathu kukukhethwa kweoli yokuthambisa, ingaba isixa sokudibanisa sichanekile, kwaye isine yi umgangatho wokuhlanganisa kunye nendawo yokusetyenziswa.
