Akoranga Take: Te Whakapai Ake i te Pakari o ngā Mekameka Roera Motopaika
Motopaikamekameka roeraKo rātou te "ora" o te pūnaha taraiwa, ā, ko tō rātou pakari ka whakatau tika i te wheako me te haumaru o te eke. Ko te tīmatanga me te tūnga pinepine i ngā haerenga ki te tāone ka tere ake te pakaru o te mekameka, ko te pānga o te paru me te onepu ki ngā whenua i waho o te rori ka taea te pakaru wawe i te mekameka. Ko ngā mekameka roera tuku iho ka pāngia e te mamae o te hiahia kia whakakapia i muri i te 5,000 kiromita noa iho. Ko Bullead, he maha ngā tau o te wheako i roto i te mara o te pūnaha taraiwa, e arotahi ana ki te "whakaoti i ngā hiahia pakari o ngā kaieke puta noa i te ao." Mā roto i ngā whakahoutanga hangarau toru-ahu i roto i ngā rauemi, te hanganga, me ngā tukanga, kua tutuki i a rātou tētahi peke kounga i roto i te pakari o ngā mekameka roera motopaika. Ka wehewehea e te rangahau take e whai ake nei ngā pānga arorau me te mahi o tēnei whakatinanatanga hangarau.
I. Ngā Whakapai Ake o ngā Rauemi: Te Hanga i tētahi Tūāpapa Mārō mō te Ātete ki te Mau me te Pānga
Ko te pūtake o te pakari ka tīmata i ngā rauemi. Ko ngā mekameka roera motopaika tuku iho he mea whakamahi i te maitai waro-iti me te pakeke o te mata (HRC35-40), ka ngāwari ai te hurihanga o te pereti mekameka me te pakaru o te pine i raro i ngā kawenga nui. Hei whakatika i tēnei raruraru, i tīmata a Bullead ki te mahi auaha i te pūtake o ngā rauemi:
1. Kōwhiringa o te Rino Koranu Parakore-Teitei
E whakamahia ana te maitai koranu chromium-molybdenum waro-teitei (hei whakakapi i te maitai waro-iti tuku iho). Kei roto i tēnei rauemi te 0.8%-1.0% waro, ā, kua tāpirihia te chromium me te molybdenum hei whakapai ake i te hanganga whakarewa—ka whakapai ake te chromium i te ātete ki te kakahu o te mata, ā, ka whakarei ake te molybdenum i te pakari o te matua, ka ārai i te mekameka kei whati nā te mea he "pakeke, he pakarukaru hoki." Hei tauira, ka whakamahia e te mekameka roera motopaika Bullead ANSI paerewa 12A tēnei rauemi mō āna pereti mekameka me ngā pine, ka hua ake he pikinga 30% o te kaha taketake ki te whakataurite ki ngā mekameka tuku iho.
2. Te Whakatinanatanga o te Hangarau Maimoatanga Wera Tika
Ka whakamahia he tukanga whakakotahi i te whakakā me te tinei me te whakamahana pāmahana iti: ka whakanohoia ngā wāhanga mekameka ki roto i te oumu whakakā wera pāmahana teitei 920℃, ka taea ai e ngā ngota waro te uru ki te paparanga mata o te 2-3mm, ā, ka whai ake ko te tinei 850℃ me te whakamahana pāmahana iti 200℃, ka tutuki ai te taurite mahi o te "mata mārō me te matua pakari" - ka eke te pakeke o te pereti mekameka ki te HRC58-62 (ātete ki te kakahu me te ātete ki te rakuraku), ko te pakeke matua kei te HRC30-35 (ātete ki te pānga me te kore e taea te huri). Manatoko mahi: I te tonga-mā-rāwhiti o Āhia (te pāmahana toharite o ia rā 35℃+, te tīmatanga-mutu pinepine), ko te roanga mahi toharite o ngā motopaika haereere 250cc kua rite ki tēnei mekameka kua piki ake mai i te 5000 km mō ngā mekameka tuku iho ki te neke atu i te 8000 km, me te kore he hurihanga nui o ngā pereti mekameka.
II. Auahatanga Hanganga: Te Whakatau i ngā Raru Ngaronga Nui e Rua o te "Waku me te Tūtaki"
E 70% o ngā rahunga o te mekameka roera i ahu mai i te waku maroke i puta mai i te "ngaronga hinu" me te "urunga poke." Ka whakaitihia e Bullead ēnei momo ngaronga e rua mā te arotau hanganga:
1. Hoahoa Ārai-Tūtaki-Rua
Mā te whakarērea o te hiri O-mowhiti tuku iho, ka whakamahia he hanganga hiri whakakotahi O-mowhiti + X-mowhiti: ka whakaratohia e te O-mowhiti te hiri taketake, ka ārai i ngā matūriki nui o te paru me te onepu kei uru; ka whakarei ake te mowhiti-X (me te wāhanga whakawhiti "X") i te taunga ki ngā pine me ngā pereti mekameka mā roto i ngā ngutu e rua-ara, ka whakaiti i te ngaronga hinu nā te wiri. I te wā kotahi, ka hangaia ngā "awaawa piko" ki ngā pito e rua o te ringaringa, ka iti ake te ngawari o te taka o te hiri i muri i te whakaurunga, ka whakapai ake i te pānga hiri mā te 60% ki te whakataurite ki ngā hanganga tuku iho. Te horopaki whakamātautau o te ao tūturu: Te eke whenua whakawhiti i ngā Maunga Āperika o Ūropi (40% ngā rori kirikiri), i whakaatuhia e ngā mekameka tuku iho te ngaronga hinu me te piri o te roera i muri i te 100 kiromita; i te mea ko te mekameka Bullead, i muri i te 500 kiromita, i mau tonu te neke atu i te 70% o te hinu i roto i te ringaringa, kāore he urunga nui o te onepu.
2. Pūnaha Hinu Āhua-Pine + Hoahoa Hongere Hinu-Iti: I ahu mai i ngā mātāpono whakahinuhinu roa i roto i te mara tuku, ka whakauruhia e Bullead he pūnaha hinu porotaka (rahinga 0.5ml) i roto i te pine, me ētahi atu hongere hinu-iti e toru, he 0.3mm te whānui, kua keria ki roto i te pakitara pine, e hono ana i te pūnaha ki te mata waku o te pakitara o roto o te ringaringa. I te wā huihuinga, ka werohia te hinu pāmahana teitei, pumau roa (awhe pāmahana -20℃ ki te 120℃). Ko te kaha porotītaha i hangaia e te hurihanga o te mekameka i te wā e eke ana ka pana i te hinu i te taha o ngā hongere hinu-iti, ka whakakī tonu i te mata waku me te whakaoti i te raruraru o te "raruraru whakahinuhinu i muri i te 300km me ngā mekameka tuku iho." Whakataurite raraunga: I roto i ngā whakamātautau eke tere-teitei (80-100km/h), i tutuki i te mekameka Bullead he huringa whakahinuhinu whai hua o te 1200km, e toru ngā wā roa atu i ngā mekameka tuku iho, me te whakaiti i te kakahu i waenga i te pine me te ringaringa mā te 45%.
III. Te Hanga Tika + Te Whakarerekētanga Āhua Mahi: Te Whakapūmau i te Pakaritanga mō ngā Āhuatanga Kanorau
Ehara te pakari i te tohu kotahi mō te katoa; me urutau ki ngā hiahia o ngā āhuatanga eke rerekē. Ka whakarite a Bullead i te mahi pumau o te mekameka i raro i ngā āhuatanga mahi rerekē mā te "hanga tika mō te tino tika + te arotautanga e hangai ana ki ngā āhuatanga":
1. Ka whakamanahia e te Huihuinga Aunoa te Tika o te Whatunga
Mā te whakamahi i tētahi raina huihuinga aunoa CNC, ka aro turukihia te piko o ngā hononga mekameka, te porowhita o te roera, me te hononga titi i te wā tūturu: ka whakahaeretia te hapa piko i roto i te ±0.05mm (ko te paerewa ahumahi he ±0.1mm), ā, ko te hapa porowhita o te roera he ≤0.02mm. Mā tēnei mana whakahaere tino tika ka whakarite "kāore he kawenga i waho o te pokapū" ina hono te mekameka ki te sprocket—ka karo i te kakahu nui i tetahi taha o te pereti mekameka i puta mai i ngā pekapeka whatunga i roto i ngā mekameka tuku iho, ka roa ake te roa o te oranga katoa mā te 20%.
2. Te Whakahoutanga Hua e Hangai ana ki te Horopaki
Hei whakatutuki i ngā hiahia kanorau mō te eke, kua whakarewahia e Bullead ngā hua matua e rua:
* **Tauira Haereere ki te Tāone (hei tauira, te 42BBH):** Kua whakapaitia te diameter o te roera (kua whakanuia mai i te 11.91mm ki te 12.7mm), kua whakanuia te horahanga pa ki te sprocket, kua whakaitihia te kawenga mō ia horahanga, kua urutau ki ngā āhuatanga tīmatanga-mutu o te tāone, ā, kua whakaroahia te roa o te ora mā te 15% ki te whakataurite ki te tauira taketake;
* **Tauira mō ngā Huarahi-Kāore:** He pereti mekameka matotoru ake (kua piki ake te matotoru mai i te 2.5mm ki te 3.2mm), me ngā whakawhiti porowhita i ngā pūwāhi ahotea matua (ka whakaiti i te kukū ahotea), ka eke ki te kaha kume o te 22kN (paerewa ahumahi 18kN), ka taea te tu atu ki ngā kawenga pānga i te ekenga ki waho o te huarahi (pērā i ngā tīmatanga pari pari me ngā taunga mai i ngā pari pari). I roto i ngā whakamātautau ki waho o te huarahi o te koraha o Ahitereiria, i muri i te 2000 kiromita o te ekenga kaha, i whakaatuhia e te mekameka he 1.2% noa iho te roa o te pitch (ko te paepae whakakapinga he 2.5%), kāore e hiahiatia he tiaki i waenganui o te haerenga.
IV. Whakamātautau o te Ao Tūturu: Te Pakaritanga i Whakamātauria i roto i ngā Horopaki o te Ao
Me whakamana ngā whakahoutanga hangarau i roto i ngā tono o te ao tūturu. I whakahaerehia e Bullead, i te mahi tahi me ngā kaihokohoko o te ao katoa, he whakamātautau mara 12-marama e kapi ana i ngā āhuarangi me ngā āhuatanga o te rori: Ngā Horopaki Wera me te Makuku Tropical (Bangkok, Thailand): 10 ngā motopaika haereere 150cc, me te haerenga toharite o ia rā he 50 kiromita, i tutuki i te roanga o te mekameka toharite he 10,200 kiromita me te kore waikura, whati rānei. Ngā Horopaki Makariri me te Mahana-Iti (Moscow, Russia): 5 ngā motopaika tere 400cc, i ekehia i roto i ngā taiao mai i te -15°C ki te 5°C, kāore i whakaatu i te here o te mekameka nā te whakamahinga o te hinu iti-tio (kore-tio i te -30°C), ā, i tutuki i te roanga o te mekameka he 8,500 kiromita. Ngā Horopaki Maunga-Tuarua (Cape Town, Āwherika ki te Tonga): E 3 ngā motopaika tuarua 650cc, e 3,000 kiromita te roa o te ekenga i runga i te rori kirikiri, ā, i mau tonu te 92% o te kaha kume mekameka tuatahi, me te mau o te roera he 0.15mm anake (paerewa ahumahi 0.3mm).
Whakatau: Ko te pakari te tikanga he "whakapai ake i te uara o te kaiwhakamahi." Ko te whanaketanga o Bullead i roto i te pakari o te mekameka roera motopaika ehara i te mea he puranga hangarau takitahi anake, engari he arotautanga whānui "mai i ngā rauemi ki ngā horopaki" - e aro ana ki ngā take matua o te "ngawari o te mau me te turuturu" mā roto i ngā rauemi me te hanganga, me te whakarite i te tono mahi a te hangarau mā te hanga tika me te urutau horopaki. Mō ngā kaieke o te ao katoa, ko te roa o te ora (he pikinga toharite neke atu i te 50%) te tikanga he iti ake ngā utu whakakapinga me te wā kore mahi, ko te mahi pono ake ka whakaiti i ngā tūponotanga haumaru i te wā e eke ana.
