(1) Pono nā sprockets moto carburized i kahi papa carburized ma ka ʻili niho. Ke hoʻohana ʻia ke kaʻina hana "carburized-warm extrusion", ʻo ka hāʻawi ʻana i ka papa carburized e pili kokoke ana i ke ʻano deformation o ka hoʻokumu ʻana. No ke kaʻina hana hoʻokaʻawale hoʻokaʻawale, hoʻokaʻawale ʻia ka papa carburized ma nā niho niho mai ka papa carburized ma ka ʻili o ka cylindrical blank. Ma ke kaʻina hana "carburizing-warm extrusion", ʻoi aku ka pōkole o ka manawa deformation, a hiki ke nānā ʻole ʻia ka diffusion o ka papa carburized. ʻOiaʻiʻo, ma hope o ka lilo ʻana o ka cylinder i mea hoʻohana, hoʻonui nui ʻia ka ʻili, a hoʻololi nui ka mānoanoa o ka papa carburized. Ke hoʻopili ʻia ka papa carburized i ka wā o ke kaʻina hana, piʻi ka mānoanoa o ka papa carburized, inā ʻaʻole, emi ka mānoanoa; a me ka papa carburized ʻO ka hoʻololi ʻana o ka mānoanoa e pili ana i ka nui o ka deformation tangential. No laila, hiki ke hoʻomalu ʻia ka māhele mānoanoa o ka papa carburized e ka hoʻomalu ʻana i ka deformation tangential o ka papa carburized i ka wā o ka extrusion mahana o ka mīkini.
