• Ukudlala nge-roller kusuka ohlangothini kuya kolunye noma ukunyakaza kwe-axial okungaphezu kuka-2 mm. Ukuvuleka kwe-axial okweqile kubonisa ukuguguleka kwe-bushing noma i-shaft futhi kuzovumela ukungahambisani kahle kwe-track chain.
• Ukuvuza kwamafutha avela ezindaweni zokuvala ezintantayo, okubonakaliswa ubumanzi, ukuqongelela kwamafutha, noma amaphethini okufutha amafutha ohlakeni lomzila.
• Ukujikeleza okubanjwe. Irola elingaphenduki ngokukhululeka lapho ithrekhi iphakanyiswa phansi—noma elikhipha imisindo yokugaya ngesikhathi sokujikeleza—liye labhekana nokwehluleka kwamabhereyi.

9.3 Amapharamitha Okufaka

I-assembly ye-800305455 yenzelwe ukushintshana okuqondile kwemishini nengxenye yokuqala. Ukufakwa ku-XE370CA kudinga:

• Ukuhlanza izindawo zokufaka uhlaka lwethrekhi ukuze kususwe udoti nezinto zokuvala ezindala
• Ukuqinisekisa ukuthi amabhore okuqondisa umgodi awanawo umonakalo noma ukuguguleka
• Ukufaka izikhonkwane zokugcina ngemininingwane ye-torque ebhalwe encwadini yesevisi yomshini we-XCMG

I-torque efanele yokufaka ibalulekile; ukugoba ngaphansi kwe-torque kungavumela ukunyakaza kwe-axial okuphazamisa ukuxhumana kwe-seal, kuyilapho ukugoba ngokweqile kungaphazamisa i-flange yokufaka noma kulimaze ukuphela kwe-shaft.

9.4 Iziqondiso Zokugcina Nokuphatha

Uma igcinwa ngaphambi kokufakwa, ama-roller angaphansi kufanele agcinwe ezindaweni ezomile, okungcono asongwe ngepakethe engangeni umhwamuko ukuze kuvinjelwe ukugqwala ezindaweni ezifakwe umshini. I-roller kufanele igcinwe ngendlela evundlile endaweni eyisicaba; ukugcina i-roller ekugcineni kwayo kungalimaza ubuso besivalo noma kuphazamise isembozo sokugcina.

Ukugingqa noma ukuwisa izinhlangano kuyingozi ekulimazeni i-flange geometry noma ubuso besivalo—ukuphathwa kufanele kwenziwe ngokuphakamisa inhlangano, hhayi ukuyigingqa. Ukuze igcinwe isikhathi eside isikhathi esingaphezu kwezinyanga eziyisithupha, i-roller kufanele ijikelezwe njalo (njalo ezinsukwini ezingu-30-60) ukuze kusatshalaliswe amafutha ezindaweni zokubeka nokuvimbela ukugqwala kwe-galvanic okusendaweni okungenzeka lapho umthwalo ogcwele we-bushing uhlala ungashintshi endaweni eyodwa yomgodi.

10. Isifinyezo Semininingwane Yobuchwepheshe

11. Isiphetho

I-XCMG XE370CA 800305455 Track Lower Roller Assembly evela ku-CQC TRACK imele ingxenye yokufaka esikhundleni senqola engaphansi kwenqola eyenziwe ngokulawulwa kwenqubo okuqinile, umklamo wensimbi othuthukisiwe, kanye nomnotho wokuhlinzekwa kwefektri oqondile. Kubaphathi bemikhumbi kanye nochwepheshe bokuthenga abathuthukisa isu labo lezingxenye zokumba i-XCMG, le nhlangano inikeza izici zokusebenza ezibhalwe phansi ezihambisana nepulatifomu yomshini engamathani angu-36.6, enokuqina kokufakwa kwe-deep-case (8-12 mm), ukuvikelwa kokungcola kwe-double-floating-seal, kanye nokuqinisekiswa kwekhwalithi okunezingqimba ezimbili kokubili ngesitifiketi sesistimu se-ISO 9001:2015 kanye nesitifiketi somkhiqizo we-CQC.

Imodeli yokukhiqiza ngqo yomkhiqizi inikeza inzuzo yeketanga lokuphakelwa ngaphezu kweziteshi zokusabalalisa ezinezigaba eziningi, isekela kokubili ama-oda okushintshana kweyunithi eyodwa yemishini ngayinye kanye namalungiselelo okugcina inani labasabalalisi. Njengoba inempahla esezingeni eliphezulu eNyakatho Melika, eYurophu, e-Afrika, naseNingizimu-mpumalanga ye-Asia, i-OEM ephelele kanye nekhono lokukhiqiza elenziwe ngokwezifiso, izikhathi zokuhola ezibiza ngokuncintisana (izinsuku ezingu-15-30), kanye nokuphila kwesevisi okweluliwe okubhaliwe (kufika ku-30% isikhathi eside kunezingxenye ezijwayelekile zemakethe yangemuva), i-CQC TRACK ibeka i-800305455 assembly njengendlela ehlukile eqinile ngobuchwepheshe futhi esebenza kahle ngokwezomnotho ngaphakathi kwemakethe yangemuva ye-crawler excavator undercarriage aftermarket.

Ngemibuzo yokuthengwa kwempahla, imininingwane yobuchwepheshe, noma izidingo zokukhiqiza ezenziwe ngokwezifiso, ukuxhumana okuqondile nomkhiqizi kuyatholakala ngeziteshi ezisemthethweni ze-CQC TRACK.
