Le seti yegiya yevili leentshulube eyayisetyenziswa kwisikhephe. Isixhobo se-34CrNiMo6 seshaft yeentshulube, unyango lobushushu: i-carburization 58-62HRC. Imathiriyeli yesixhobo seNtshulube CuSn12Pb1 Tin Bronze. Igiya yevili leentshulube, ekwaziwa njengegiya yeentshulube, luhlobo lwenkqubo yegiya edla ngokusetyenziswa kwizikhephe. Yenziwe ngumbungu oyicylindrical (ekwaziwa ngokuba sisikrufu) kunye nevili lentshulube, eliyigiya eyicylindrical enamazinyo asikwe ngokwepateni yehelical. I-worm gear meshes kunye ne-worm, idala ukuhanjiswa okugudileyo kunye nokuzola kwamandla ukusuka kwi-shaft yokufaka kwi-shaft yokuphuma.

Kwizikhephe, iigiya zamavili entshulube zihlala zisetyenziselwa ukunciphisa isantya se-propeller shaft. Isixhobo se-worm sinciphisa isantya se-shaft yokufaka, ehlala idityaniswe kwi-injini, kwaye idlulisela loo mandla
