Te hononga kaiwhakarato whai mana mō CQCTRACK – Pūtake wheketere tika mō ngā wāhanga o raro o te waka taumaha

1. CQCTRACK Hiranga Hanga – OEM, ODM, Whakaritenga Kore-Paerewa me te Pūmautanga o te Hua

Ehara a CQCTRACK i te takawaenga hokohoko engari he hoa hanga me te miihini whakauru e tohunga ana ki ngā otinga mahi taumaha mō ngā keri 100 tana neke atu. E toru ngā rerenga uara motuhake e tukuna ana e tā mātou pūnaha whakaputa:

• Ngā Kaihanga OEM – Ka mahi tahi mātou me ngā whare hanga me ngā whare hanga kua whakamanahia e te ISO 9001:2015 me te IATF 16949 e hanga ana i ngā wira mangere kia rite ki ngā whakaritenga rauemi taketake a Hitachi (40CrMnMo, rite rānei). Ka whakamanahia ia huihuinga ki ngā paerewa ā-ahu kua whakaputaina e Hitachi (JIS D 0006) me ngā kōtaha maimoatanga wera (taahi whakapakeke whakauru: 52–55 HRC, hohonu o te pouaka ≥6 mm). Kāore he rerekētanga o ngā tauira kōhao pūtu, ngā diameter o te pou, te kōpiko rānei o te flange.
• Ngā Kaiwhakarato ODM – Mō ngā waka keri e rapu ana i ngā whakapainga mahi i tua atu i te hoahoa taketake, ka hangaia anō e tā mātou tīma hangarau ODM ngā atanga matua. Ko ētahi tauira ko:
  – Kua whānuitia te kōtaha flange (+4 mm) hei whakaiti i te kōpiritanga o te mekameka ara i ngā āhuatanga paru.
  – Hiritanga takirua-kōne kua whakapai ake me te elastomer fluorocarbon (awhe mahi -50°C ki te +150°C).
  – Ngā momo hanga rerekē (hei tauira, 35CrMoV) mō ngā keri kohatu pānga nui.
  Kua tuhia ngā whakarerekētanga ODM katoa me ngā tau wāhanga kua whakahoutia me te hototahi whakamuri katoa.
• Whakaritenga Kore-Paerewa – Ka whakaaetia e mātou ngā ota takitahi, ngā ota iti rānei ina kore e tau te rahinga o ngā taonga paerewa. Ko ngā tono noa ko:
  – He pou whakangā roa ake mō ngā anga ara kua whakarerekētia (ātete ±2 mm).
  – Ngā tauira kōhao o te whāriki whakairi kāore i te paerewa (ira, imperial rānei).
  – Te pakeke o te mata tae atu ki te 58 HRC mō te kaha o te karawarawa silica.
  Te wā ārahi mō te whakaaetanga tuhi hangarau: 48 hāora (ka mahi tahi te tīma a Jack me ngā kaiwhakahaere kounga o te wheketere).

Ka whakamanahia te pumau o te hua puta noa i ngā wāhanga mahi taumaha katoa o te raupapa EXC mā te porowhita whakahaere kounga kua tuhia:

• Whakamātautau ultrasonic 100% o ngā papa hanga (kāore he āputa o roto, kāore hoki he whakaurunga).
• Whakatauira kawenga hihiri – 2 miriona huringa i te kawenga pūmau kua whakatauria he 1.5× (he rite ki te 4,500 hāora mahi maina).
• Whakamātautau manawanui hiri – 500 hāora o te rumakina ki roto i te paru kirikiri (ranunga onepu/wai) me te kore e taea te ine i te urunga.

E whakaatu ana ngā raraunga mara mai i te tau 2023–2025 i te wā toharite i waenga i ngā rahunga (MTBF) neke atu i te 3,200 hāora mō ngā huihuinga mangere CQCTRACK i runga i ngā mīhini akomanga EX1200‑5 – he pai ake te mahi i ngā momo mīhini whai muri o te taumata iti mā te 35%.

2. Whakaahuatanga Taipitopito o te Wāhanga me ngā Hua o raro o te Kawe

2.1Huihuinga Wira o te Ara Whakangāwari(Huinga Wāhanga-Toru)

E toru ngā tau tohutoro takitahi e whakauruhia ana e te huihuinga hei hanga i te waeine mahi kotahi. Kaua e tono motuhake – he mea hanga ki te wheketere ēnei.

Tuhipoka whakawhitiwhiti:Ka whakakapi tika tēnei huihuinga i te Hitachi OEM idler me te kore e shimming, e welding rānei. I manatokohia mā te whakamātautau whakauru ki ngā tau rangatū EX1200‑5 1001–2500.

2.2 Ngā Wāhanga o raro o te EXC Mahi Taumaha e Pā Ana (Tuku Pūnaha Katoa)

Ka whakaratohia e CQCTRACK tētahi raina raro katoa mō te EX1200‑5. He rite tonu te paerewa kounga OEM o ngā hua katoa, ā, he mea hanga mai i te wheketere:

• Mekameka Ara (Kua Hiritia, Kua Whakahinuhinuhia) – Te piko 260 mm, 49 hononga. Te pakeke o te titi 58–60 HRC, te whakakaha o te pūwero kua whakapakeketia ki te 55 HRC. Kua whakakīia ki te hinu, ngā hiri O-ring. Hononga i hangaia mai i te 40Mn2.
• Hu Ara – 600 mm te pūwero takitoru (keri), 700 mm te pūwero takirua (nekehanga oneone whānui), 800 mm rānei te papatahi (repo). Momo pūmau.
• Rōra Kawe – Nama tāpiri 2036450. Tinana hanga, hiri takirua e mānu ana. Kua pania ki te hinu mō te wā roa.
• Rōra Ara o raro – He rua ngā parirau, 180 mm te whānui o waho. E rua ngā whāriki mō ia rōra. He kakau ka taea te whakamahi anō.
• Wāhanga Pītiti – 23 ngā niho, he awhi pūtu. He mea hanga ki te maitai Q&T 350 HB. He tohu mau kua maka ki ngā taha o ngā niho.

Kei te wātea ngā wāhanga katoa i te takitahi, i te kete rānei mō raro i te waka EXC katoa (he utu whakaheke 7% mō te huinga katoa). Kei roto i ia kete ngā whakatakotoranga taipana tāutanga me ngā pepa ine kakahu.

Mā Jack (Māngai Hangarau me ngā Take Ao o CQC), kua tukuna e CQCTRACK ngā huihuinga idler EX1200‑5 ki ngā mahi keri puta noa i ngā whenua e rima. Kua manatokohia te hua i te mara i raro i ngā āhuatanga tino kino e whai ake nei:

• Ahitereiria – Te rohe o te rino o Pilbara. Te pāmahana 42–48°C, te kukū o te silica i te rangi >0.5 mg/m³. Kāore he pakaru o ngā papa o ngā waka CQCTRACK i mua i te 3,500 hāora (te toharite OEM: 3,200 hāora).
• Amerika ki te Tonga
  –Ecuador(Te kokoru o Amazon): Ka rumakina tonutia te paru, ka neke atu i te 90% te haumākū. Ka ārai te hiri rūpahu i te urunga o te paru.
  –Parahi(Carajás, Pará): Te pānga kaha mai i ngā kohatu rino rahi-mita. He tinana hanga kua whakamatautauria ki te pūngao pānga 40 kJ, kāore he whati.
  –Wenehūera(Orinoco Mining Arc): He laterite whakakoi me te pH 4–5. Ka ātete te whakakikorua konutea i runga i te whāriki ki te waikura waikawa.
• Rūhia me Āhia Waenga – Siberia (Yakutia): Te mahi hotoke i te ‑45°C. Hinu pāmahana iti (Akomanga NLGI 0) me te matua maitai ngāwari (pāmahana whakawhiti pānga ‑50°C). Kazakhstan (ngā maina parahi): Kua paahitia te whakamātautau urunga puehu maroke, pai.
• Ūropi me Āhia ki te Hauāuru – Turkey (ngā maina boron): Ātete matū ki te kohu waikawa boric. Saudi Arabia (ngā maina phosphate Al Jalamid): Te pakū onepū – te tere o te kakahu o te papa ≤0.08 mm ia 100 hāora. UAE (ngā maina takutai): Kua manatokohia te ātete ki te kohu tote.
• Kōrea me Īnia – Ngā maina waro Kōrea (he nui te utaina hurihuri). Ngā rua kōhatu karāhe Īnia (ngā para koki koi) – kāore he pakaru wawe o te flange.
• Āwherika – Īhipa (Koraha Uru): Oneone kirikiri pai – he nui rawa te ngutu hiri hei ārai i te mirimiri. Āwherika ki te Tonga (Bushveld Complex): Keri konukawata kei raro i te whenua, ngā āhuatanga haukū – he whai hua te paninga ārai-waikura. Kana (ngā maina koura): Para waikawa – he whāriki kua pania ki te epoxy ki te ātete pH 2.

Urupare tika a te kiritaki (i tuhia e te tari o Jack's i te hauwhā tuarua o te tau 2025):
"I whakakapia e mātou ngā idlers OEM ki ngā waeine CQCTRACK i runga i ngā EX1200‑5 e toru i tā mātou maina Brazil. I muri i ngā hāora 2,800, ko te taumahatanga toharite o te mau o te flange he 1.2 mm, ki te whakataurite ki te OEM 1.8 mm. Ka tono atu mātou i ētahi atu 12."– Kaiwhakahaere tiaki, Minas Gerais.
