2.3 Te Hanga me te Maka: Ngā Whakaaro Hangarau

Ko te tikanga hanga—te hanga me te whakarewa—he pānga nui ki te mahi a te sprocket me te roa o te mahi i roto i ngā mahi keri:

Ngā Pīrere Whakarewa: Ka whakatikatika te tukanga whakarewa i te hanganga o roto o te maitai, ka whakakore i te porosity, ka whakarite i te rere o te maitai ki ngā ara ahotea matua o te wāhanga. Ko te hua he āhuatanga miihini pai rawa atu tae atu ki te kaha pānga teitei ake, te ātete ngenge pai ake, me te ātete nui ake ki te pakaru kino i raro i ngā kawenga tino nui. Mā te whakarewa tika wera (te whakarewa pēhi me te kuti tika) ka taea te hanga i ngā wāhanga pīrere mā te tukanga māmā ake, ka whakaiti i te wā hanga me te utu me te pupuri i te mana whakataetae.

Ngā Pīrere Maka: Mā te maka ka taea te hanga i ngā āhuahanga niho uaua, ā, he iti ake te utu mō ngā rahinga whakaputa. Heoi, tera pea he pūngao ā-roto, he whakaurunga rānei kei roto i ngā wāhanga maka ka taea te mahi hei wāhi tīmatanga pakaru i raro i te kawenga huringa. Nā konei, ko ngā pīrere keri mō ngā tono pānga nui ka tohua hei wāhanga hanga kaua ki te maka.

Ka whakamahia e CQC TRACK ngā tikanga hanga e rua i runga i te tau wāhanga me ngā whakaritenga tono, me ngā sprocket kounga teitei i hangaia mā roto i ngā tukanga hanga mate-kati mā te whakamahi i ngā maitai koranu 52Mn, 55Mn, me te 40CrNiMo, kia pai ai te rere o te witi me te mātotoru rauemi i roto i ngā wāhanga para, he mea nui mō te kaha pānga me te roa o te ora ngenge.

3. Te Hangarau Maimoatanga Wera

3.1 Ngā Mātāpono Whakarewa mō ngā Whakamahinga Sprocket

Ko te maimoatanga wera te mahi hanga tino nui e whakatau ana i te roa o te ratonga o te sprocket i roto i ngā mahi keri. I roto i te ao o ngā mīhini taumaha, ka whawhai tonu ngā wāhanga o raro i te waku, te pēhanga, me ngā taiao whakakoi. Ka mahi ia sprocket, roera, me te hu ara i raro i te kawenga nui me te pānga maha. Hei ora i roto i ēnei āhuatanga kino, he mea nui te pakeketanga o te rauemi—ā, ko te whakatutuki i taua pakeketanga ka whakawhirinaki ki te maimoatanga wera tika.

Ehara i te mea he mahi hanga noa te maimoatanga wera; he pūtaiao e huri ana i te maitai i te taumata ngota. Mā roto i ngā huringa whakamahana me te whakamatao e whakahaeretia ana—te tinei me te whakamahana i te nuinga—ka tutuki i te konganuku he taurite tika i waenga i te pakeke me te pakari. Mō ngā wāhanga o raro o te waka keri, ka whakatau tēnei taurite i te roa o te wā e taea ai e te wāhanga te tu atu i mua i te ngenge, te whakarerekētanga rānei.

Ko te tukanga tinei te tīmatanga o te kaha tūturu o te maitai. Ka whakamahanahia te wāhanga ki tētahi pāmahana tino nui (i te nuinga o te wā i waenganui i te 850–900°C), ka huri tōna hanganga tioata hei austenite. Kātahi ka tere te whakamatao—mā te rumakina ki te wai, ki te hinu rānei. Mā tēnei hekenga pāmahana ohorere ka mau tonu ngā ngota waro ki tōna tūranga, ka hanga he hanganga moroiti tino mārō engari he pakarukaru e mōhiotia ana ko te martensite. Koinei te āhua o te hanga o te mata mārō, ātete-kakahu e tika ana mō ngā niho porotiti.

3.2 Tikanga Whakamātao me te Whakamātao

Ahakoa he mārō te whakamātao, ka puta mai anō hoki he pakarukaru. Ko te whakamātao te taahiraa whai muri nui e whakaiti ana i ngā ahotea o roto, e whakahoki mai ana hoki i te ngāwari. Ka whakamahanahia anō te wāhanga ki tētahi pāmahana iti iho, e whakahaeretia ana (i waenga i te 150–500°C) ā, ka puritia mō tētahi wā motuhake i mua i te whakamātao puhoi. Ka whakaitihia paku e tēnei tukanga te mārō rawa engari ka whakapai ake i te pakari, te ātete pānga, me te ngāwari. Ko te hua he huinga tino pai—he mata mārō, ātete ki te kakahu me te matua kaha, ngāwari—he tino pai mō ngā porotiti me tu atu ki ngā kawenga hihiri me ngā ru.

Ka roa ake te pupuri a ngā pīkau niho i ngā kōtaha niho tika, kia pai ai te hononga ki ngā mekameka ara. Ka whakaitihia te pakaru o te mekameka, ā, ka ārai i te pakaru wawe.

3.3 Ngā Whakatakotoranga Pakari

Mō ngā poro Hitachi EX300-1/2/3, ko te pakeke o te mata kei waenga i te HRC 42 ki te HRC 56 i runga i te whakaritenga hanga motuhake, e whakaiti ana i te pakaru me te whakaroa i te roa o te ora. Ko ngā poro kounga teitei mō ngā mahi keri nui ka tutuki te pakeke o te mata o te HRC 52–58 me te hohonu o te pouaka o te 8–12mm, e whakarato ana i te roa o te ora pakaru i raro i ngā āhuatanga pakaru nui tae atu ki ngā oneone keri whai kiko-silica, ngā rori kawe toka pakaru, me ngā rauemi uta-nui-silica.

3.4 Te Mana Kounga me te Tūturutanga

Me tino kaha te whakahaere i te kounga o te tukatuka wera whai hua. Me aroturuki tonu ngā kaihanga i te ōritetanga o te pāmahana, te wā rumaki, te tere whakamatao, me te hanganga whakarewa kia tutuki ai ngā whakaritenga mahi. Mā te kore aro ki ēnei tawhā—te whakawhirinaki rānei ki te maimoatanga wera koretake—ka tino whakapoto i te roa o te ora o te wāhanga. Ahakoa ngā rerekētanga iti o te pāmahana i te wā e tinei ana, e whakamahana ana rānei, ka arahi pea ki te pakeketanga kore taurite, ka puta te kakahu wawe, te pakaru, te kore pumau rānei o te āhua.

Ko ngā wāhanga i hangaia ki ngā koranu matatau me ngā maimoatanga wera ka whakamatautauria kia rite te pakeke, te ātete pānga, me te kaha ngenge. Mā tēnei taumata kounga ka whakaitihia te tūponotanga o ngā rahunga ohorere, ā, ka whakarite kia roa te mahi a ngā mīhini i te taumata teitei rawa atu.
