(1) Koi ʻia nā sprockets mokokaikala Carburized i kahi papa carburized ma luna o ka niho. Ke hoʻohana ʻia ke kaʻina hana "carburized-warm extrusion", pili kokoke ka puʻunaue ʻana i ka papa carburized me ka deformation method of gear e hana ana. No ke kaʻina tangusion split extrusion, ua hāʻawi ʻia ka papa carburized ma nā niho kapa mai ka papa carburized ma luna o ka hakahaka o ka paukūʻolokaʻa. I ke kaʻina hana "carburizing-warm extrusion" o nā kia, ʻoi aku ka pōkole o ka manawa deformation, a hiki ke nānā ʻole ʻia ka diffusion o ka papa carburized. ʻIke nō, ma hope o ka lilo ʻana o ka paukū i lole, hoʻonui nui ʻia ka ʻilikai, a hoʻololi nui ka mānoanoa o ka papa carburized. Ke hoʻopili maʻalahi ʻia ka papa carburized i ke kaʻina hana, piʻi ka mānoanoa o ka papa carburized, a i ʻole, e emi ka mānoanoa; a me ka carburized, ahu iho Ka loli mānoanoa hilinaʻi nui i ka nui o ka tangential deformation. No laila, hiki ke kāohi ʻia ka mānoanoa o ka papa carburized e ka kaohi ʻana i ka deformation tangential o ka papa carburized i ka manawa o ka extrusion mehana o nā kapa.
(2) Ma ke kumu o ka hoʻomaopopo ʻana i ke kaʻina hana o ka mokokaikala sprocket niho, ke kūkā kamaʻilio hou aʻe e pili ana i ka loli mai ka papa hana o ka paukū i ka paukū carburized o nā kapa ke hana i ka ʻāpana o ka ʻāpana: ka paukū e kaomi ʻia e nā niho wahine Ka ʻili lilo ka pelekane carburized i ka papa carburized o ka ʻāpana aʻa gear. Pono ka loli mai ka pae o ka paukū i ka ʻāpana aʻa niho, a ʻo ka mea i komo mua i ka deformation, ʻoi aku ka nui o ka helu hoʻonui, ʻo ka lahilahi o ka papa carburized; ma ka mea ʻē aʻe, ma muli o ka extrusion make ke hana ka pihi i ka ʻāpana concave o ka ʻāpana puʻe e lilo i aʻa o ka niho, ʻo ka metala o ka ʻāpana puʻe o ka make ma waena o ka mea hao a me ka ʻāpana radial o ka hao i lilo i ka niho niho ʻāpana, ʻāpana ʻia kēia ʻāpana o ka hao e nā niho ʻelua pili pili make i luna, a laila māhuahua ka mānoanoa o ka papa carburized; ke piʻi ka deformation, inā pili ka pilina me ka punahelu wahine i ka lawa pono o ka moʻo wahine, hoʻoliʻiliʻi ka mānoanoa o ka papa carburized ke kūlou.
