Iyi seti yegiya remavhiri rehonye raishandiswa muchikepe. Material 34CrNiMo6 yeworm shaft, kurapwa kwekupisa: carburization 58-62HRC. Worm giya zvinhu CuSn12Pb1 Tin Bronze. A worm vhiri giya, rinozivikanwawo seworm giya, imhando yegiya system inowanzoshandiswa muzvikepe. Inoumbwa necylindrical worm (inozivikanwawo se screw) uye vhiri rehonye, iro giya recylindrical rine mazino akachekwa mune helical pateni. Iyo honye giya meshes nehonye, ichigadzira yakatsetseka uye yakanyarara kutapurirana kwesimba kubva kune yekupinza shaft kuenda kune inobuda shaft.
