Leli sethi legiya lesondo lezikelemu elalisetshenziswa esikebheni. Material 34CrNiMo6 for worm shaft, ukwelashwa ukushisa: carburization 58-62HRC. Izinto zegiya lezikelemu CuSn12Pb1 Tin Bronze. Igiya lesondo lezikelemu, elaziwa nangokuthi igiya lezikelemu, wuhlobo lwesistimu yegiya elivame ukusetshenziswa ezikebheni. Yakhiwe yisibungu esiyicylindrical (esaziwa nangokuthi isikulufu) kanye nesondo lezikelemu, okuyigiya eliyicylindrical elinamazinyo asikwe ngephethini ye-helical. Igiya lezikelemu lihlangana nesikelemu, lidale ukudluliswa kwamandla okubushelelezi nokuthule ukusuka ku-shaft yokufaka kuya ku-output shaft.
Ezikebheni, amagiya esondo lezikelemu avame ukusetshenziselwa ukunciphisa isivinini se-propeller shaft. Igiya lezikelemu linciphisa isivinini se-input shaft, evame ukuxhunywa enjinini, bese lidlulisela lawo mandla
