(1) Iisprocket zesithuthuthu ezifakwe kwi-carburized zifuna umaleko we-carburized kwindawo yezinyo. Xa inkqubo "ye-carburized-warm extrusion" isetyenzisiweyo, ukuhanjiswa komgangatho we-carburized kuhambelana ngokusondeleyo kwindlela yokuguqula i-gear forming. Kwinkqubo ye-tangential yokwahlulwa kwe-extrusion, umaleko we-carburized kumazinyo egiya uphinde usasazwe kuluhlu lwe-carburized kumphezulu we-cylindrical blank. Kwinkqubo ye-"carburizing-warm extrusion" yeegiya, ixesha lokuguqulwa lifutshane, kwaye ukusabalalisa kwe-carburized layer kunokungahoywa. Ngokucacileyo, emva kokuba i-cylinder ibe yigiya, indawo ephezulu yanda kakhulu, kwaye ubukhulu be-carburized layer butshintsha kakhulu. Xa i-carburized layer igxininiswe ngokukhawuleza ngexesha lenkqubo yokuqulunqa, ubuninzi be-carburized layer buyanda, ngaphandle koko, ubukhulu buyancipha; kunye ne-carburized layer Ukutshintsha kobuninzi kuxhomekeke kubungakanani be-tangential deformation. Ke ngoko, ukuhanjiswa kobuninzi bomaleko we-carburized kunokulawulwa ngokulawula ukuguqulwa kwe-tangential yomaleko we-carburized ngexesha lokufudumala kwegiya.
(2) Ngokwesiseko sokuqonda inkqubo yokwenziwa kwamazinyo e-sprocket yesithuthuthu, ingxoxo eyongezelelekileyo malunga notshintsho ukusuka kumaleko we-carburized we-cylinder ukuya kumaleko we-carburized wegiya xa kusenziwa inxalenye yegiya: isilinda esicinezelwe ngamazinyo abasetyhini Umphezulu. umaleko carburized iba umaleko carburized inxalenye gear ingcambu. Utshintsho kufuneka lube kwi-cylinder surface ukuya kwingcambu yezinyo, kwaye kwangaphambili ithatha inxaxheba kwi-deformation, isantya sokwandisa, i-thinner layer ye-carburized; ngokuchaseneyo, ngenxa ye-die extrusion Xa uxinzelelo lusenza inxalenye ye-concave yecandelo loxinzelelo ibe yingcambu yezinyo, isinyithi secandelo loxinzelelo lwe-die phakathi kwentsimbi kunye nenxalenye ye-radial yentsimbi iba yi-crest yezinyo. inxalenye, le nxalenye yentsimbi icinezelwe ngamazinyo amabini akufutshane acandekileyo acandekileyo phezulu, emva koko Ubunzima bomgangatho we-carburized buyanda; xa i-deformation inyuka, ukuba ukudibanisa kunye nokubumba kwabasetyhini kuxhomekeke kwi-friction eyaneleyo ye-female mold, ubukhulu be-carburized layer bunokuncitshiswa xa ukolula kwenzeka.
