(1) Ama-sprocket wezithuthuthu ezishisiwe adinga ungqimba owenziwe nge-carburized endaweni yezinyo. Lapho inqubo "ye-carburized-warm extrusion" isetshenziswa, ukusatshalaliswa kwesendlalelo se-carburized kuhlobene eduze nendlela yokuguqulwa kokwakhiwa kwamagiya. Ngenqubo ye-tangential split extrusion, ungqimba lwe-carburized emazinyweni egiya lusatshalaliswa kabusha lusuka kungqimba lwe-carburized ebusweni be-cylindrical blank. Enqubweni ye-"carburizing-warm extrusion" yamagiya, isikhathi se-deformation sifushane, futhi ukusabalalisa kwesendlalelo se-carburized kungase kunganakwa. Ngokusobala, ngemva kokuba isilinda sibe igiya, indawo engaphezulu iyanda kakhulu, futhi ukushuba kongqimba lwe-carburized kushintsha kakhulu. Lapho ungqimba lwe-carburized lucindezelwa nge-tangentially ngesikhathi sokwakhiwa, ubukhulu bengqimba ye-carburized buyanda, ngaphandle kwalokho, ubukhulu buyancipha; kanye nesendlalelo se-carburized Ushintsho lokujiya luncike enanini le-tangential deformation. Ngakho-ke, ukusatshalaliswa kogqinsi kwesendlalelo se-carburized kungalawulwa ngokulawula ukuguqulwa kwe-tangential kwesendlalelo se-carburized ngesikhathi sokufudumala kwegiya.
(2) Ngokwesisekelo sokuqonda inqubo yokwakheka kwamazinyo e-sprocket yesithuthuthu, enye ingxoxo mayelana noshintsho ukusuka kungqimba olushisiwe lwesilinda ukuya ongqimbeni olushisiwe lwegiya lapho kwakhiwa ingxenye yegiya: isilinda esicindezelwe amazinyo esifazane ungqimba owenziwe nge-carburized uba ungqimba lwe-carburized lwengxenye yempande yegiya. Ushintsho kufanele lusuke endaweni ye-cylinder kuya endaweni yempande yezinyo, futhi ekuqaleni lubamba iqhaza ekuguqulweni, izinga lokunwetshwa likhulu, lincane ungqimba lwe-carburized; ngokuphambene nalokho, ngenxa ye-die extrusion Lapho ingcindezi yenza ingxenye ye-concave yengxenye yokucindezela ibe impande yezinyo, insimbi yengxenye yokucindezela yokufa phakathi kwensimbi nengxenye ye-radial yensimbi iba i-crest yezinyo. ingxenye, le ngxenye yensimbi icindezelwa amazinyo amabili aseduze ahlukanisayo phezulu, bese Ukuqina kongqimba lwe-carburized kuyanda; lapho i-deformation ikhula, uma ukuthintana nesikhunta sesifazane kungaphansi kokungqubuzana okwanele kwesikhunta sesifazane, ubukhulu bengqimba ye-carburized bungancishiswa lapho ukwelula kwenzeka.
