Kuramba kw'imashini icukura amabuye y'agaciro: Hitachi EX1800 / EX1900 Track Sprocket Wheel Assembly

1. Intangiriro: Umugongo w'Ubucukuzi bw'Amashami Ahanitse

Mu rwego rw'ubucukuzi bunini bw'amabuye y'agaciro, ubucukuzi bw'amabuye y'agaciro, n'ubwubatsi bukomeye, uruhererekane rwa Hitachi EX1800 na EX1900 ni byo byerekana imikorere y'ubucukuzi bw'amazi. Kubera ko uburemere bw'imikorere burenga toni 180 n'ubushobozi bwo gucukura indobo bugera kuri metero kibe 15, izi mashini zikora mu bihe bidashira - imitwaro myinshi, ibikoresho byo gukurura, n'imikorere ihoraho.

Ihuriro ry'amapine ya Track Sprocket (rizwi kandi nka "track chain sprocket assy") ni igice cy'ingenzi gihindura ingufu za hydraulic mo gukurura. Ku bikorwa byo gucukura amabuye y'agaciro mu bucukuzi bw'umuringa muri Chili, mu birombe bya platine byo muri Afurika y'Epfo, cyangwa mu mirima y'amabuye y'agaciro yo mu Burusiya, kuba iri huriro ryizewe bigena intego z'umusaruro n'ikiguzi kuri toni.

Iyi nkuru itanga isesengura ryimbitse rya tekiniki ry’itsinda ry’ibikoresho by’ubwiza bwa OEM bigaragazwa n’imibare y’ibice1028990,4451622, na4637264, byakozwe hakurikijwe amabwiriza akomeye yaITSINDA RYA CQC—icyitegererezo cyihariyeuruganda rutanga isokonaumuhinziby'ibice biremereye bya EXC by'imodoka iri munsi y'imodoka.

2. Ibisobanuro bya tekiniki n'uburyo bwo guhinduranya

2.1 Kugaragaza ibice

Imibare itatu y'ibice ihuye n'impinduka z'itsinda ry'ibikoresho bikoreshwa kuri platform za Hitachi EX1800 na EX1900:

• 1028990: Ubusanzwe yerekeza ku gice cyuzuye cy'uruziga rw'ipine (hub + impeta) ku miterere yihariye ya nyuma y'imodoka.
• 4451622: Ikunze kujyana n'impeta y'imashini igabanyijemo ibice cyangwa iteranyirizwa ry'ibikoresho bya EX1900 byo mu cyiciro cya nyuma.
• 4637264: Akenshi bivuze agakoresho k'igice cy'umugozi cyangwa impeta yo kwambara kuri bolt, bigatuma habaho gusimbuza field hatabayeho gukuraho moteri ya nyuma yo kuyitwara.

Izi nteguro zakozwe kugira ngo zihuze n'icyuma gifasha mu rugendo cya Hitachi (gikunze kugira igikoresho cyo gushyiramo imigozi cyangwa imigozi) kandi zagenewe iminyururu y'inzira ifite umuvuduko wa mm 317 cyangwa mm 350, bitewe n'imiterere y'igare riri munsi y'imodoka.

2.2 Ibiranga ubwubatsi bukomeye

Bitandukanye n'ibice byo gucukura bifite ubunini buri hagati, agace ka EX1800/EX1900 kubatswe kugira ngo gashobore kwihanganira:

• Ingufu zo gusohora amashanyarazi menshi: Ingufu zizenguruka zigera kuri 1,500 kN·m.
• Gucika intege cyane: Gukomeza gukora ku ibuye rikomeye, amabuye y'agaciro, n'ibintu byinshi biremereye.
• Gutungurwa: Biterwa n'ubutaka butaringaniye n'impinduka zitunguranye mu cyerekezo.

Ubusanzwe iyi teraniro iba ifite imiterere itandukanye, igizwe n'ibice byinshi by'amenyo (akenshi ibice 3 kugeza kuri 5 kuri buri sprocket) bishobora gusimburwa ukwabyo, bigabanyiriza cyane igihe cyo kubikora ndetse n'amafaranga yo kubika ibikoresho by'inyongera.

3. Uburyo bwo kuvura ibyuma n'ubushyuhe mu bijyanye n'ubucukuzi bw'amabuye y'agaciro

Kugira ngo ihabwe agaciro ko kuba igice cy’imodoka ziremereye za EXC, imashini igomba kurenza ibisabwa bisanzwe by’ibikoresho.ITSINDA RYA CQCikoresha inzira yo gukora ijyanye na ISO 9001:2015 n'uburyo bwiza bwo gucukura amabuye y'agaciro.

3.1 Ingano y'ibikoresho

• Icyuma cyakozwe mu bucuzi: Icyuma gifite aloyi nyinshi ya chromium-molybdenum (urugero, 40CrNiMo cyangwa kimwe kingana nacyo) cyatoranijwe mu rwego rwo gukomera cyane no kurwanya umunaniro wo gutembera.
• Imiterere ya Mekanike: Ingufu z'umusaruro ≥ 900 MPa, imbaraga zo gukurura ≥ 1.080 MPa, bishimangira ubuziranenge bw'imiterere y'icyuma mu gihe cy'imizigo myinshi.

3.2 Porogaramu yo Gutunganya Ubushyuhe

• Binyuze mu gukomeretsa: Impeta yose ya sprocket inyura mu gupfuka no kuzimya kugira ngo igere ku bukomere bumwe (35–40 HRC).
• Gukomera kw'amenyo: Impande z'amenyo n'umuzi w'amenyo bikomera kugeza kuri 52–58 HRC kugeza kuri mm 12–15 z'ubujyakuzimu, bigatuma ubuso budashobora kwangirika mu gihe hagumana igice gikomeye cyo hagati kugira ngo kiyirinde.
• Gushyushya: Uburyo bwo gushyushya bugenzurwa bugabanya imihangayiko isigaye kandi bukagabanya ibyago byo gukwirakwira kw'iminyururu mu duce dukonje (urugero, ubucukuzi bwa Siberiya).

3.3 Igenzura ry'Ubuziranenge

Buri cyiciro cy'umusaruro gishyirwa mu byiciro bikurikira:

• Isuzuma rya Ultrasonic (UT): Kugira ngo harebwe imyanda cyangwa ibintu biri mu byuma bicukurwamo.
• Igenzura ry'uduce twa Magnetic Particles (MPI): Igenzura ryimbitse ry'agace k'amenyo n'imyobo y'amapine.
• Igenzura ry'ibipimo: Igenzura rya CMM ry'umurambararo w'umuvuduko, imiterere y'amenyo, n'ubuziranenge bw'uruziga rw'umunyu kugeza kuri ± 0.5 mm.

4. Ibisabwa ku isoko ry'akarere n'imiterere yaryo

Hitachi EX1800 na EX1900 zikoreshwa mu bucukuzi bw'amabuye y'agaciro busaba akazi kenshi ku isi ndetse n'ubwubatsi bukomeye. Iteraniro ry'ibikoresho rigomba guhuza n'imiterere y'ibikorwa by'akarere.

5. Ubuhanga mu by'Inganda:ITSINDA RYA CQCnk'uruganda rutanga isoko

Nk’uruganda rwihariye rukora ibikoresho bikomeye bya EXC munsi y’imodoka, CQC TRACK yitandukanya binyuze mu buhanga bwo guhuza imodoka no gukora imashini.

5.1 Ubushobozi bw'uruganda

• Gucukura no Gutera: Imirongo yo gucukura mu nzu ishobora gukora uduce duto dufite umurambararo wa mm 2,500.
• Imashini za CNC: amashami 5 yo gucukura amenyo neza no gucukura imyobo y'amenyo.
• Ibikoresho byo Gutunganya Ubushyuhe: Utunyangingo dukomeza gukurura induction twikora hamwe n'ubushyuhe mu gihe nyacyo kugira ngo harebwe uburebure bw'ubushyuhe buhamye.
• Umurongo wo gusiga: Gukoresha irangi rya polyurethane cyangwa epoxy riramba cyane mu kurwanya ingese mu mazi no mu bidukikije birimo ubushuhe bwinshi.

5.2 Inkunga y'Ubwubatsi

CQC TRACK itanga:

• Ubwubatsi bw'inyuma: Ubushobozi bwo kwigana uduce duto duto twakoreshejwe mu ngero zashaje, bigatuma habaho imiterere nyayo y'ibishushanyo mbonera bya kera.
• Guhindura imiterere y'amenyo: Guhindura imiterere y'amenyo cyangwa imitako y'amenyo kugira ngo ijyane n'imiterere idasanzwe ya nyuma yo kuyikoresha.
• Inyandiko za tekiniki: Gutanga ibishushanyo mbonera by'ingano, imiterere y'ubukana, n'ibyemezo by'ibikoresho (EN 10204 3.1) kugira ngo bihuze n'ibisabwa mu gutanga amasoko.

5.3 Guhuza na OEM

Iteraniro ry'imibare y'ibice1028990, 4451622, 4637264byagenewe guhuza cyangwa kurenza ibyagenwe na Hitachi by’umwimerere, bitanga:

• Guhinduranya: Gusimbuza bolt-on direct nta mpinduka.
• Guhinduranya ibice: Bihuye n'udupira tw'ibice bya OEM n'udupira two kumesa.

6. Kunoza Ikiguzi cy'Ingengo y'Imari

Ku mato manini y’ubucukuzi bw’amabuye y’agaciro, kubungabunga ubwikorezi bw’igare munsi y’imodoka ni igice kinini cy’ikiguzi cy’imikorere. Guhitamo uburyo bukwiye bwo guteranya ibyuma:

• Uburyo bwo kwambara iminyururu: Amenyo y’inkono akomeye neza yongerera igihe cyo guhagarara neza binyuze mu gukomeza gushyira umuvuduko mu mwanya ukwiye.
• Kugabanya Igihe cyo Kudakora: Imiterere y’amenyo igabanyijemo ibice ituma ibice by’amenyo byiyongera mu masaha ari munsi ya 4, ugereranije no gusimbuza amenyo yose ashobora gusimburana burundu.
• Gucunga ububiko: Gushyira ibice by'ububiko aho gushyira ibiziga byuzuye bigabanya imari n'umwanya w'ububiko.

7. Umwanzuro: Ubuhanga bwo gukora amasaha menshi

Hitachi EX1800 na EX1900 byakozwe kugira ngo bikore neza, ariko ibice byabyo biri munsi y'imodoka ni byo bigena uburyo bwo gukomeza gukora neza. Uburyo bwo guhuza urushundura rwa Track Sprocket—bwaba buzwi nka 1028990, 4451622, cyangwa 4637264—bugomba gutanga uburambe buhamye, ubushobozi bwo guhuza neza, no koroshya kubungabunga.

Gukorana n'uruganda rwihariye rukora ibicuruzwa nka CQC TRACK bitanga umusaruro uhagije:

• Ubucukuzi bw'amabuye y'agaciro: Bwagenewe gushwanyagurika no gukomeretsa.
• Urusobe rw'Ibicuruzwa ku Isi: Gahunda zo kubika ibicuruzwa zigenewe uturere ducukura amabuye y'agaciro (Antofagasta, Johannesburg, Yakutia, Alberta, n'ibindi).
• Gukurikirana no kwemeza: Inyandiko zuzuye zijyanye n'amabwiriza agenga amasoko y'ubucukuzi bw'amabuye y'agaciro.

Ku bakoresha ibirombe, ba nyiri ibikoresho, ndetse n'abacuruza ibikoresho nyuma y'isoko, gushora imari mu guteranya ibikoresho by'agaciro si ugusimbura gusa—ni ingamba zo kugabanya ikiguzi kuri toni no gukoresha neza umutungo.

Icyitonderwa: *Hitachi, EX1800, na EX1900 ni ikirango cyanditswe cya Hitachi Construction Machinery Co., Ltd. Nimero z'ibice 1028990, 4451622, na 4637264 zikoreshwa gusa mu buryo bwo kurebera hamwe. CQC TRACK ni uruganda rwigenga rukora ibikoresho byo mu modoka zigendanwa kandi ntirufitanye isano na Hitachi.*
