Te kaupapa mahi
Ki te pekepeke ngā wira maui me matau ki runga, ki raro i te wā kotahi, arā, ko te tinana anake e neke poutū ana, ā, he ōrite te rerekētanga o te whakatārewatanga i ngā taha e rua, ka huri noa te pae whakaū whakawhiti i roto i te pūwero, kāore te pae whakaū whakawhiti e mahi.
Ina kore e ōrite te rerekētanga o ngā taha e rua o te whakatārewatanga ki te tinana mō te piko taha o te rori, ka neke te taha o te anga ki te taha o te tautoko puna, ka neke ake te taha o te pae whakaū ki te anga, ā, ka neke iho te taha o te anga ki te taha o te tautoko pere matā, ka neke iho te pae whakaū e rite ana ki te anga, engari i te piko o te tinana me te anga, kāore he nekehanga whanaunga i waenganui o te pae whakaū whakawhiti i runga i te anga maroke. Pēnei, ina piko te tinana, ka peka te taha roa o te pae whakaū i ngā taha e rua ki ngā ahunga rerekē, nō reira ka takahurihia te pae whakaū, ā, ka piko te ringa taha ki te whakanui ake i te pakari o te koki o te whakatārewatanga.
Mā te taipana ā-roto i hangaia e te pae whakaū rapa ka ārai i te whakarerekētanga o te anga pere, ā, ka whakaitihia te piko taha me te wiri taha o te tinana. Kāore e mahi ngā pito e rua o te ringa tokotoko i te ahunga kotahi o te pae whakaū whakawhiti peke, ina huri te wira maui me te wira matau, ka huri te wāhanga waenga o te pae whakaū whakawhiti mā te hurihanga.
Mena he iti te pakari o te koki taha o te waka, he nui rawa rānei te koki taha o te tinana, me whakamahi te pae whakaū taha hei whakanui ake i te pakari o te koki taha o te waka. Ka taea te tāuta motuhake, te tāuta rānei i ngā pae whakaū taha i te wā kotahi ki te whakatārewatanga o mua me muri e ai ki te hiahia. I te wā e hoahoa ana i te pae whakaū whakawhiti, me te whakaaro anō ki te pakari katoa o te koki hurihuri o te waka, me whakaaro anō hoki ki te ōwehenga o te pakari o te koki hurihuri o te whakatārewatanga o mua me muri. Kia whai āhuatanga urungi-kore te waka, me nui ake te whakatārewatanga o mua i te whakatārewatanga o muri o te pakari o te koki taha. Nō reira, he maha atu ngā tauira e tāutahia ana ki te pae whakaū taha whakatārewatanga o mua.
Ko te tikanga, ka tīpakohia ngā rauemi i runga i te ahotea hoahoa o te pae whakaū whakawhiti. I tēnei wā, ko ngā rauemi 60Si2MnA te mea e whakamahia nuitia ana i Haina. Mō te whakamahinga o te pae whakaū taha ahotea teitei ake, e taunaki ana a Hapani kia whakamahia te maitai Cr-Mn-B (SUP9, SuP9A), kaua te ahotea o te pae whakaū teitei me te maitai waro (S48C). Hei whakapai ake i te roa o te mahi o te pae whakaū whakawhiti, me mahi te pupuhi pupuhi.
Hei whakaiti i te papatipu, ka hangaia ētahi pae whakaū whakawhiti ki te paipa porowhita tuwhera, ā, ko te ōwehenga o te matotoru o te pakitara paipa rino me te diameter o waho e tata ana ki te 0.125. I tēnei wā, ka piki ake te diameter o waho o te tokotoko totoka mā te 11.8%, engari ka taea te whakaiti i te papatipu mā te 50%.
