Imishini ye-Helicalpinion shaftidlala indima ebalulekile ekusebenzeni kahle kwama-gearbox e-helical, avame ukusetshenziswa ezimbonini ezifana nezezimoto, ukukhiqiza amandla, kanye nokukhiqiza. Amagiya e-helical anamazinyo ancike e-engeli, okuvumela ukudluliswa kwamandla abushelelezi futhi athule uma kuqhathaniswa namagiya aqondile.
I-pinion shaft, igiya elincane ngaphakathi ku-gearbox, ixhunywe negiya elikhudlwana noma isethi yegiya. Lokhu kulungiselelwa kunikeza ukudluliselwa kwetorque okuphezulu ngokudlidliza okuncishisiwe nomsindo. Idizayini yayo iqinisekisa ukusatshalaliswa okungcono komthwalo kuwo wonke amazinyo amaningi, ithuthukisa ukuqina kwesistimu yegiya.
Izinto ezifana nensimbi ye-alloy noma i-case-hardened steel ngokuvamile zisetshenziselwa ama-pinion shafts ukumelana nemithwalo esindayo nokuguga. Ukwengeza, lezi shaft zithola ukunemba kwemishini nokwelashwa kokushisa ukuze kuqinisekiswe ukuqondana okunembile nempilo ende yesevisi.
