Mhando dzegiyareducer worm giya inoderedza isimba rekufambisa dhizaini rinoshandisa inomhanyisa shanduko yegiya kudzikisa huwandu hwekuchinja kwemota kune inodiwa nhamba yekuchinja uye kuwana yakakura torque michina. Muchigadziriso chinoshandiswa kufambisa simba uye kufamba, huwandu hwekushandisa hwekudzikisa hwakanyanya. Matanho ayo anogona kuoneka muhurongwa hwekutapurirana kwemhando dzese dzemuchina kubva mungarava dzemotokari dzinorema muchina wekuvaka, kugadzira michina uye otomatiki michina yekugadzira inoshandiswa muindasitiri yemuchina kumidziyo yakajairika yemumba mumawachi ehupenyu hwezuva nezuva etc. kuonekwa kubva pakufambiswa kwesimba guru kune kutapurirwa kwemitoro miduku uye kona chaiyo. Mumaindasitiri ekushandisa, iyo inoderedza ine mabasa ekudzikisa uye torque kuwedzera. Naizvozvo, inoshandiswa zvakanyanya mukumhanyisa uye torque kushandura michina.

Kuti uvandudze kushanda kweiyogiya rehonye kuderedza, simbi dzisina ferrous dzinowanzo shandiswa segiya rehonye uye simbi yakaoma sehonye shaft. Nekuti inotsvedza friction drive, panguva yekushanda, inoburitsa kupisa kwakanyanya, izvo zvinogadzira zvikamu zvekudzikisa uye chisimbiso. Pane mutsauko mukuwedzera kwekupisa pakati pavo, zvichiita kuti pave nemukaha pakati penzvimbo imwe neimwe yekusangana, uye mafuta anove akaonda nekuda kwekuwedzera kwekushisa, izvo zviri nyore kukonzera kuvuza. Pane zvikonzero zvina zvikuru, chimwe ndechekuti kufananidzwa kwezvinhu zvine musoro, imwe imhando yepamusoro yemeshing friction surface, chechitatu kusarudzwa kwemafuta ekuzora, kana huwandu hwekuwedzera hwakarurama, uye chechina kunaka kwekusangana uye nzvimbo yekushandisa.
