Iizixhobo zempethui-reducer yindlela yokudlulisa amandla esebenzisa i-speed converter yegiya ukunciphisa inani lee-revolutions zemoto (i-motor) ukuya kwinani elifunekayo lee-revolutions kwaye ifumane i-torque mechanism enkulu. Kwindlela esetyenziselwa ukudlulisa amandla kunye nokuhamba, uluhlu lwe-reducer lubanzi kakhulu. Imigca yayo inokubonwa kwinkqubo yokudlulisa zonke iintlobo zoomatshini, ukusuka kwiinqanawa, iimoto, ii-locomotive, oomatshini abanzima bokwakha, oomatshini bokucubungula kunye nezixhobo zokwenza ngokuzenzekelayo ezisetyenziswa kushishino loomatshini, ukuya kwizixhobo eziqhelekileyo zasekhaya kubomi bemihla ngemihla. , iiwotshi, njl. Ukusetyenziswa kwe-reducer kunokubonwa ukusuka ekudlulisweni kwamandla amakhulu ukuya ekudlulisweni kwemithwalo emincinci kunye ne-engile echanekileyo. Kwizicelo zoshishino, i-reducer inemisebenzi yokunciphisa isantya kunye nokunyuka kwe-torque. Ke ngoko, isetyenziswa kakhulu kwizixhobo zokuguqula isantya kunye ne-torque.

Ukuze kuphuculwe ukusebenza kakuhle kwesixhobo sokunciphisa izixhobo zemibungu, iintsimbi ezingezizo i-ferrous zihlala zisetyenziswa njengesixhobo semibungu kwaye intsimbi eqinileyo isetyenziswa njenge-worm.umngxumaNgenxa yokuba yi-sliding friction drive, ngexesha lokusebenza, iya kuvelisa ubushushu obuphezulu, okwenza iindawo zesinciphisi kunye nesitywini. Kukho umahluko ekwandeni kobushushu phakathi kwazo, okubangela umsantsa phakathi komphezulu ngamnye wokudibana, kwaye ioyile iba ncinci ngenxa yokunyuka kobushushu, okulula ukubangela ukuvuza. Kukho izizathu ezine eziphambili, esinye kukuba ingaba ukufana kwezinto kufanelekile na, esinye ngumgangatho womphezulu womphezulu wofriction we-meshing, esesithathu kukukhethwa kweoyile yokuthambisa, nokuba ubungakanani bokongeza buchanekile na, kwaye esesine ngumgangatho wokuhlanganiswa kunye nendawo yokusetyenziswa.
