Bonzeigiya lezikelemu Isondo elisetshenziswa ku-gearbox, Belonukukhiqizwa kwegiya lezikelemuisinciphisi segiya lezikelemu siyindlela yokudlulisa amandla esebenzisa isiguquli sejubane segiya ukwehlisela isibalo sokuguquguquka kwemoto (motor) enanini elidingekayo lokuguquguquka futhi ithole indlela enkulu yetorque. Igiya le-Belon worm Endleleni esetshenziselwa ukudlulisa amandla nokunyakaza, uhla lokusetshenziswa lwesinciphisi lubanzi impela. Umkhondo wayo ungabonakala ohlelweni lokudlulisa lwazo zonke izinhlobo zemishini, kusukela emikhumbi, izimoto, izitimela, imishini esindayo yokwakha, ukucubungula imishini kanye nemishini yokukhiqiza ezenzakalelayo esetshenziswa embonini yemishini, kuya ezintweni ezisetshenziswa zasendlini ezijwayelekile emawashi okuphila kwansuku zonke njll. ukusetshenziswa kokunciphisa kungabonakala kusukela ekudlulisweni kwamandla amakhulu kuya ekudlulisweni kwemithwalo emincane kanye ne-angle eqondile. Kuzinhlelo zokusebenza zezimboni, isinciphisi sinemisebenzi yokunciphisa nokunyuka 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, esinye siwukuthi ukufanisa izinto kunengqondo, esinye izinga eliphezulu le-meshing friction surface, okwesithathu ukukhethwa kwamafutha okugcoba, noma inani lokungezwa lilungile, kanti okwesine izinga lokuhlanganisa kanye nendawo yokusetshenziswa.
