Isinciphisi segiya lezikelemu siyindlela yokudlulisa amandla esebenzisa isiguquli sejubane segiya ukwehlisa isibalo sokuguquguquka kwemoto (motor) enanini elidingekayo lokuguquguquka futhi ithole indlela enkulu yetorque. Endleleni esetshenziselwa ukudlulisa amandla nokunyakaza, uhla lohlelo lokusebenza lwesinciphisi likhulu kakhulu. Imikhondo yayo ingabonakala ohlelweni lokudlulisela lwazo zonke izinhlobo zemishini, kusukela emikhunjini, ezimotweni, ezinqoleni, imishini esindayo yokwakha, imishini yokucubungula kanye nemishini yokukhiqiza ezenzakalelayo esetshenziswa embonini yemishini, kuya ezintweni ezivamile zasendlini ekuphileni kwansuku zonke. , amawashi, njll. Ukusetshenziswa kokunciphisa kungabonakala kusukela ekudlulisweni kwamandla amakhulu kuya ekudlulisweni kwemithwalo emincane kanye ne-angle eqondile. Kuzinhlelo zokusebenza zezimboni, isinciphisi sinemisebenzi yokunciphisa nokwenyuka kwe-torque. Ngakho-ke, isetshenziswa kabanzi kumishini yokuguqula isivinini kanye ne-torque.
Ukuze kuthuthukiswe ukusebenza kahle kwesinciphisi segiya lezikelemu, izinsimbi ezingenayo insimbi ngokuvamile zisetshenziswa njengegiya lezikelemu kanye nensimbi eqinile njengomphini wezikelemu. Ngenxa yokuthi i-sliding friction drive, ngesikhathi sokusebenza, izokhiqiza ukushisa okuphezulu, okwenza izingxenye ze-reducer kanye ne-seal. Kunomehluko ekwandeni okushisayo phakathi kwazo, okuholela egebeni phakathi kwendawo ngayinye yokukhwelana, futhi uwoyela uba mncane ngenxa yokwanda kwezinga lokushisa, okulula ukubangela ukuvuza. Kunezizathu ezine eziyinhloko, esisodwa ukuthi ukufanisa izinto kunengqondo, esinye izinga eliphezulu le-meshing friction surface, okwesithathu ukukhethwa kwamafutha okugcoba, ukuthi inani lokwengeza lilungile, kanti okwesine izinga lokuhlanganisa kanye nendawo yokusetshenziswa.
