Izixhobo ze-Helicalpinion shaftidlala indima ebalulekileyo ekusebenzeni ngokufanelekileyo kweebhokisi zegiya ze-helical, eziqhele ukusetyenziswa kumashishini afana neemoto, ukuvelisa amandla, kunye nokuvelisa. Iigiya ze-helical zinamazinyo athambekele kwi-engile, evumela ukuhanjiswa kwamandla athambileyo kunye nokuzola xa kuthelekiswa nezixhobo ezisikiwe ngokuthe tye.
I-pinion shaft, igiya encinci ngaphakathi kwebhokisi yegiya, i-meshes enegiya enkulu okanye iseti yegiya. Olu lungelelwaniso lunikeza ukuhanjiswa kwetorque ephezulu kunye nokungcangcazela okuncitshisiweyo kunye nengxolo. Uyilo lwayo luqinisekisa ukuhanjiswa komthwalo ongcono kumazinyo amaninzi, ukwandisa ukuqina kwenkqubo yegiya.
Izinto ezifana nentsimbi yealloy okanye i-case-hardened steel zihlala zisetyenziselwa i-pinion shafts ukumelana nemithwalo enzima kunye nokunxiba. Ukongeza, ezi shafts zifumana ukuchaneka komatshini kunye nonyango lobushushu ukuqinisekisa ulungelelwaniso oluchanekileyo kunye nobomi benkonzo obude.
