(1) Ko nga pukoro motopaika kua oti te whakakakahu me whai paparanga waro ki runga i te mata niho. I te wa e whakamahia ana te tukanga "carburized-warm extrusion", ko te tohatoha o te paparanga carburized e hono tata ana ki te tikanga deformation o te hanga taputapu. Mo te tukanga tangohanga wawahanga tangential, ka tohatohahia te paparanga carburized i nga niho taputapu mai i te paparanga carburized i runga i te mata o te porotakaroa. I roto i te tukanga "carburizing-warm extrusion" o nga taputapu, he poto ake te wa deformation, a ka kore e arohia te whakamaaramatanga o te paparanga carburized. Ma te mohio, i muri i te noho o te cylinder hei taputapu, ka nui haere te waahi o te mata, ka rereke te matotoru o te paparanga carburized. A, no te te tangentially kōpeke te paparanga carburized i roto i te tukanga hanga, te matotoru o te apa carburized piki ake, ki te kore, ka heke te matotoru; me te paparanga carburized Ko te huringa matotoru ka whakawhirinaki ki te nui o te deformation tangential. Na reira, ko te tohatoha matotoru o te paparanga carburized ka taea te whakahaere ma te whakahaere i te whakarereketanga tangential o te paparanga carburized i te wa o te wera o te taputapu.
(2) I runga i te maarama ki te hanga o nga niho pupuhi motopaika, he korero ano mo te huringa mai i te paparanga carburized o te rango ki te paparanga carburized o te taputapu i te wa e hanga ana i te waahanga taputapu: te rango i pehia e nga niho wahine Te mata Ko te paparanga carburized ka waiho hei papa carburized o te waahanga pakiaka taputapu. Me huri te huringa mai i te mata porotakaroa ki te mata pakiaka niho, me te wa o mua ka uru ki te huringa, ka nui ake te tere toronga, ka angiangi te paparanga carburized; i runga i te anga ke, na runga i te tangohanga mate Ka hanga e te pehanga te wahanga concave o te wahanga pehanga hei pakiaka o te niho, ko te konganuku o te wahanga o te pehanga o te mate i waenga i te whakarewa me te wahanga radial o te konganuku ka noho hei tihi niho. wahi, Ko tenei wahi o te whakarewa e kōpeketia e te rua tata mate wehe niho i runga, ka piki te matotoru o te apa carburized; ka nui haere te deformation, ki te i raro i te whakapā ki te pokepokea ai wahine ki rawaka waku o te pokepokea ai wahine, kia heke te matotoru o te apa carburized ka puta totoro.
