1. Kuzivikanwa kweZvikamu & Kubatanidzwa kweSisitimu

Mutambo weTrack Idler Assembly, unonziwo Track Guide Wheel Assembly (Nhamba Yekutanga Yechikamu: YA60041974), chikamu chechassis chakagadzirwa zvakanaka, chakagadzirwa zvakanaka, chakabatanidzwa nehurongwa hweHITACHI ZX450, ZX470, uye ZX490. Yakagadzirwa neHELI (CQCTRACK) semutengesi weOriginal Equipment Manufacturer (OEM) uye mubatsiri weOriginal Design Manufacturer (ODM), chigadzirwa ichi ndicho gwara guru rekutungamira uye magumo ekutanga ekumanikidza cheni yemuchina wekuchera. Dhizaini yayo uye mashandiro ayo zvakakosha pakuona kugadzikana kwenguva refu, kubatana kwakakodzera kweshangu dzemumugwagwa, uye kufambiswa kwesimba zvinobudirira panguva yekufambisa nekufamba netsoka.

2. Mabasa Ekutanga Ekushanda & Basa reKinematic

• Kutungamira & Kurongeka kweTrack Chain: Inopa nzvimbo yakaoma, inotenderera yedatamu inotungamira zvakanyatsonaka magungano ekubatanidza etrack chain, ichivimbisa kurongeka kweaxial nguva dzose sezvo cheni ichipinda munzira yepamusoro yengoro, nokudaro ichidzivirira kufamba-famba uye kubuda munjanji.
• Kudzora Kusimba Kwesimba: Senzvimbo yakasungirirwa yesimbi ye hydraulic kana kuti ine mafuta, chidhiraivha chinotumira simba rinogadziriswa remberi kune cheni yese yenzira. Kuchengetedza kusimba kwakakwana kwakakosha pakuderedza kurasikirwa kwesimba, kuderedza "kupwanya" kwenzira kana kuti kurova, uye kudzivirira kupera kwemapini, mabushing, uye mazino e sprocket nguva isati yakwana.
• Kuparara kweMutoro Wekukanganiswa: Inotora uye inoparadzira mitoro yekutanga yakatwasuka neyakatwasuka kana cheni yenzira yakabatana panguva yekufamba kwemuchina pamusoro penzvimbo dzisina kurongeka, ichidzivirira furemu yenzira uye ma weld echimiro kubva kuneta kwekushushikana.
• Kugadzika Kwemuchina Wepasi Pemotokari: Inoshanda sechibatiso chechimiro chemberi chinotsanangura uye chinochengetedza chiyero chakakodzera chenzira (daro riri pakati pemitsara yepakati yenzira dzakafanana), zvakakosha pakugadzikana kwemuchina uye kutevedza mutsetse wakatwasuka.

3. Kuumbwa Kwakadzama Kwechivakwa & Uinjiniya Wezvinhu

Maitiro ekugadzira eHELI eODM/OEM eYA60041974Kugadzira kunosanganisira simbi yepamusoro uye machining akarurama:

• Wheel/Rim yeIdler: Yakagadzirwa nesimbi yakagadzirwa uye yakajairika (semuenzaniso, 50Mn kana yakaenzana nayo). Nzvimbo inoyerera inosimbiswa zvishoma nezvishoma kuti iwane kuomarara kwakadzika, kunodzorwa (kazhinji kuomarara kwenzvimbo yeHRC 58-62, nekuomarara kwakasimba kweHRC 30-40), zvichiita kuti irambe yakasimba pakugumburwa panosangana mabhazi emumugwagwa uku ichiramba iine simba rekugumburwa.
• Integral Flanged Hub & Shaft: Ine shaft yesimbi ine simba rakawanda, inogadziriswa nekupisa, inogona kunge yakapatsanurwa kana kusungirirwa makiyi uye yakadzvanywa mu flange hub yakagadzirwa. Majenali e shaft bearing akagadzirwa zvakanaka kusvika pa micron-level uye anowanzo shandiswa chrome kana nitride kuti irambe yakasakara uye inodzivirira ngura panzvimbo dzinosangana ne bearing contact.
• Kugadzika Kwemabheya Ane Hunhu Hwakakwirira: Inoshandisa mabheya maviri akafanana eLarge-bore Tapered Roller Bearings (TRBs) kana Double-Row Spherical Roller Bearings. Kugadzika uku kwakasarudzwa zvakananga kuti kutarisise mitoro mikuru ye radial kubva pahuremu hwemuchina uye mitoro yakakura ye axial thrust inogadzirwa panguva yekutendeuka kwakasimba uye kushanda kwe side-hill kunoratidzwa nema excavators ekirasi yeZX450-490.
• Sisitimu Yepamusoro Yekuvharira Zvikamu Zvizhinji: Inosanganisira chisimbiso chemaziso che radial chakabatanidzwa nechisimbiso chedivi chinoyangarara uye chidziviriro cheguruva chekunze che multi-labyrinth. Iyi sisitimu yekudzivirira katatu yakazara nemafuta e-lithium-complex ane simba guru, kumanikidzwa kwakanyanya (EP) kuti igadzire chipingamupinyi chisingapindiki kubva kuzvinhu zvidiki zvinobvisa simba (guruva remugodhi, silica) uye kupinda kwemvura, kunyangwe mumamiriro ekushambidzwa nemhepo ane simba guru.
• Zvikamu zveKugadzirisa Interface: Zvinosanganisira mhete dzakaomarara uye dzakakuyiwa kana mabushing anotsiviwa akagadzirwa nebronze yakanyudzwa nemafuta kana simbi yakaomeswa pamusoro. Izvi zvinobatana neslide yekugadzirisa yefuremu yenzira, zvichibvumira kufamba kwakapfava uku zvichigadzirwa sezvikamu zvekuchengetedza simbi yepakati uye chimiro chefuremu.
• Zvivakwa Zvekuzora: Zvakashongedzwa nemafuta emhando yepamusoro ehydraulic (semuenzaniso, ST-type) kuti zvive nyore kuchengetedza nzvimbo huru yekutakura zvinhu pamwe nenzvimbo dzinotsvedza dzemabushing.

4. Kugona Kugadzira HELI (CQCTRACK) OEM/ODM

Pamusangano weYA60041974, HELI inoshanda pasi pemitemo yakasimba yeOEM neODM:

• Kutevedzera OEM: Inogadzira zvinhu zvinoenderana neHitachi Engineering Standards (HES) chaiyo, kusanganisira kusimbiswa kwezvinhu zvizere, kuenderana nehukuru hwechinhu, uye kusimbiswa kwekushanda, kazhinji kuti zviendeswe zvakananga kuHitachi's assembly lines kana network dzezvikamu dzakabvumidzwa.
• Hunyanzvi hweODM: Inopa masevhisi ekugadzira zvinhu (DFM) uye ekugadzira kukosha, ichipa mhinduro dzakagadzirwa senge kuvandudzwa kwezvinhu, kuwedzerwa kwechisimbiso, kana kugadzirisa huremu hwenzvimbo dzakatarwa dzekushanda pasina kukanganisa zvinodiwa pakushanda.
• Kufamba Kwakabatana Kwekugadzira: Inoshandisa nzira yekugadzira yakavharirwa: Dhizaini yesimbi yekugadzira yeCNC → kugadzira otomatiki → kutonhora kwakadzorwa → kugadzira kwakashata → kuderedza kushushikana → kupedzisa kugadzira → kurapwa kwekupisa nekombiyuta → kukuya & kukwenenzvera → kuchenesa kweultrasonic → kuisa mabheyaringi/chisimbiso otomatiki → kumaka nelaser → kuyedza kwekupedzisira.
• Kuvimbisa Hunhu Uye Kutevedza: Inoshandisa sisitimu yakazara yeMushumo weZvinhu (MTR). Batch yega yega inoedzwa zvisingaparadze (MPI/DPI), kuongororwa kwehudzamu hwekuoma, kuyedzwa kwekumanikidzwa kwechisimbiso, uye kuongororwa kwetorque inotenderera. Zvikamu zvakaiswa makodhi emhando dzakasiyana kuti zvinyatsoteererwa.

5. Magadzirirwo ehunyanzvi uye Ruzivo rwekushanda

• Kuvimbika Kwemadimikira: Kunoenderana chaizvo nedhayamita rekunze rakatarwa naHitachi (OD), Upamhi Hwose, Dhayamita yeBore, Kureba kweFlange, uye Patani yeBolt.
• Kuyera Kutakura Kunochinja: Yakagadzirwa kuti ipfuure zvinodiwa zvekutakura zvinochinja zveZX450-490 series, zvichiita kuti pave nekuchengetedzwa kushoma sezvinoenderana neISO 10262 kana zvimwe zvakafanana zvemichina inofamba nevhu.
• Kushanda kweSeal: Yakaedzwa kuti igone kunyudzwa mumvura uye kusukwa nechisimba zvichienderana neISO 3457 (static sealing) nekubuda kwemafuta mashoma kana kupinda kwetsvina.
• Kushivirira Kwezvakatipoteredza: Yakagadzirirwa tembiricha yekushanda inotangira pa -25°C kusvika +80°C, ine mafuta nezvinonamira zvakatsanangurwa zvinoenderana.

6. Kushandiswa, Kugadzirisa & Kuchinjana

• Mashandisirwo Akananga: Mamodheru eHitachi ZX450LC, ZX470LCH, ZX490LCH, uye mhando dzawo dzakasiyana.
• Kuchinjana: Kutsiva zvakananga, bhoti-ne-bhoti pakubatanidza kwekutanga kweHitachi YA60041974. Kutarisa-tarisa kunofanira kugara kuchisimbisa huwandu hwenhamba dzemuchina kuti pave nekuvandudzwa kweinjiniya.
• Kuyera Kupfeka & Hupenyu hweSevhisi: Zviyero zvakakosha zvekupfeka zvinosanganisira kuderedzwa kwerim OD uye kutetepa kwehupamhi hweflange. Kuyera nguva dzose zvichienderana nezvinodiwa nefekitori kwakakosha. Hupenyu hwesevhisi hunowedzerwa nekuchengetedza kusimba kwakakodzera kwenzira uye kuchenesa marara kubva mugomba riri pakati peidler nefuremu yenzira.
• Kutsiva Nehurongwa: Kuti zvinhu zvisanyanya kuoma uye zvishande zvakanaka, kutsiva munhu asina simba kunofanirwa kuongororwa pamwe chete nemamiriro echeni yenzira (mapini nemabushing), sprocket (marimu kana mubatanidzwa wese), uye macarrier rollers kudzivirira kusakara nekukurumidza pazvikamu zvitsva.
