Umkhiqizi Womthombo: I-HELI Machinery Manufacturing Co., Ltd. (CQCTRACK)

1. Isifinyezo Esiphezulu: Ubunjiniyela Isisekelo Sokuhamba Kwezimayini Ezisezingeni Eliphezulu

Esigabeni semishini yokumba i-hydraulic yezinga eliphezulu, i-undercarriage imelela ukuxhumana okubalulekile phakathi kwamandla omshini kanye nokutholakala kokusebenza. Kwi-KOMATSU PC1250—umshini osebenza njalo ngemikhawulo yokuqina komshini ekumbeni okuvulekile, ukwakhiwa okunzima kwezakhiwo, kanye nokumba izimayini ezinkulu—ubuqotho bengxenye ngayinye ye-undercarriage buhlobene ngqo nesikhathi sokukhiqiza, ukuphepha, kanye nezindleko eziphelele zobunikazi.

I-Track Bottom Roller Assembly (ebizwa nangokuthi i-Upper Track Roller noma i-Return Roller) equkethe izinombolo zokubhekiselaKM2503,21N3000120,21N3000121,21N3000122, 21N3000123Yakha umndeni wezingxenye eziklanywe ngokunemba oklanyelwe ngqo uchungechunge lwe-KOMATSU PC1250. Yakhiwe yi-HELI Machinery Manufacturing Co., Ltd., esebenza ngaphansi kophawu lwe-CQCTRACK, lezi zingxenye zenzelwe hhayi nje njengezingxenye ezithathelwa indawo kodwa njengezixazululo eziklanywe ngobunjiniyela ezibhekana nezindlela ezithile zokwehluleka kanye nezidingo zokusebenza ezitholakala kuzinhlelo zokusebenza zesevisi enzima.

Lo mbhalo unikeza incazelo ephelele yobuchwepheshe yalo mndeni wezingxenye, uchaza ifilosofi yobunjiniyela, isayensi yezinto ezibonakalayo, izinqubo zokukhiqiza, kanye nezinhlaka zokuqinisekisa ikhwalithi ezihlukanisa lezi zinhlangano neminikelo evamile ye-aftermarket.

2. Ukuhlonza Umkhiqizo kanye ne-Cross-Reference Matrix

Ukuhlonza izingxenye ngendlela enembile kuyisinyathelo esiyisisekelo ekuthengweni kwemishini yokumba esezingeni eliphezulu. I-matrix elandelayo isungula ubudlelwano phakathi kwezinombolo zokubhekisela ezahlukahlukene kanye nomongo wazo wokusetshenziswa.

3. Indima Yokusebenza Esistimu Yokuthwalwa Kwezisu

Ukuqonda umsebenzi wokusebenza kwe-carrier roller assembly kubalulekile ukuze kuqashelwe izinqumo zobunjiniyela ezilawula ukwakheka kwayo, ukukhethwa kwezinto, kanye nezinqubo zokukhiqiza.

3.1 Imisebenzi Eyinhloko Yokusebenza

Ngaphakathi komklamo we-chassis yethrekhi ye-KOMATSU PC1250, i-roller assembly engezansi yenza imisebenzi emithathu ebalulekile eqinisekisa ubuqotho bohlelo lwe-undercarriage:

1. Ukusekelwa Kweketanga Lethrekhi Elingezansi: Libekwe eceleni kwe-flange ephezulu yohlaka lwethrekhi, ama-carrier rollers athwala isisindo esingaguquki nesiguquguqukayo sokubuya kweketanga lethrekhi. Lokhu kusekelwa kuvimbela ukugoba okukhulu obekungakhulisa ukuhudula kwezinambuzane futhi kusheshise ukuguguleka kwezixhumanisi zethrekhi kanye nama-bushings.
2. Ukuphathwa Kokucindezeleka Kwethrekhi: Ngokusekela umucu ongaphezulu ngezikhathi ezithile, ama-carrier rollers agcina i-geometry efanele yokugoba kwethrekhi. Lokhu kuthinta ngqo amandla okucindezeleka adluliselwa ku-track tensioner kanye ne-recoil spring assembly, okufaka isandla ekucindezelweni kokuxhumana komhlaba okuqhubekayo kanye nokusebenza komshini okuzinzile.
3. Isiqondiso Nokuqondanisa Kwaseceleni: Umklamo we-double-flange we-carrier roller uhambisana nokuhlanganiswa kwe-track link ukuze kulondolozwe ukuhambisana okunembile kwe-return run. Lo msebenzi wokuqondisa uvimbela ukuphuma kwe-track ngesikhathi sokujika futhi unciphisa ukulayisha okusemaphethelweni okungasheshisa ukuguguleka kokubili ku-track chain kanye ne-roller flanges.

3.2 Umongo Wokuhlanganiswa Kwesistimu

I-Bottom roller isebenza ngokuvumelana nezingxenye ezilandelayo ze-undercarriage ukwakha uhlelo lokugqoka oluhlanganisiwe:

• Ukuhlanganiswa Kwe-Track Chain: Indawo yokusebenza ye-carrier roller ithinta izixhumanisi zangemuva ze-track link, lapho ama-flange ethinta ubuso bezixhumanisi.
• Ama-Upper Track Rollers (Ama-Bottom Rollers): Sekela isisindo esiphelele sokusebenza komshini entanjeni engezansi
• Isondo Lokuvilapha Lomkhondo: Linikeza isiqondiso sokuya phambili kanye nokuxhumana ngendlela yokucindezela ithrekhi
• I-Drive Sprocket: Idlulisela i-torque ejikelezayo kusuka ku-drive yokugcina iye ku-track chain

4. Ukwakhiwa Kobuchwepheshe: I-Anatomy ye-KM2503 Carrier Roller Assembly

Ukusebenza kwe-carrier roller ekusetshenzisweni kokumba kunqunywa ukuhlanganiswa okuhlangene kwezinhlelo zayo ezingaphansi. Lokhu kususwa okulandelayo kuchaza imininingwane yobunjiniyela esetshenziswe enkambisweni yokukhiqiza ye-HELI CQCTRACK.

4.1 Uhlelo Lomzimba Ojikelezayo kanye Nesibani: Olubunjiwe Ukumelana Nokuklwebheka

Umzimba we-roller umelela isikhombikubona sokuguguleka esiyinhloko futhi kufanele ngesikhathi esifanayo ubonise ubulukhuni obukhulu bomphezulu ukuze kumelwane nokuguguleka kanye nokuqina okwanele kwengaphakathi ukuze kufakwe umthelela.

Ukukhethwa Kwezinto:

• Umzimba we-roller wakhiwe nge-micro-alloyed boron steel formulation (isb., 40MnB noma 50Mn grade)
• Amapharamitha okwakha alawulwa ukuvumelanisa ukugeleza kokusanhlamvu kwensimbi nokwakheka kwejometri kwengxenye, okudala isakhiwo se-anisotropic esinamandla okushaya aphezulu uma kuqhathaniswa nezinye izindlela zokwenziwa.
• Lokhu kwakhiwa okuhlanganisiwe kubalulekile ekilasini le-PC1250, lapho imithwalo yomthelela evela emisebenzini yokumba ingadlula u-200% wesisindo sokusebenza esingaguquki.

Ubunjiniyela beFlange:

• I-assembly inesistimu yokuqondisa enezinhlangothi ezimbili ehlelwe ngokunemba kumaphrofayili aqinile
• I-geometry ye-Flange ilungiselelwe ukusebenzisana ngqo nezixhumanisi ze-KOMATSU PC1250 track link.
• Ubukhulu be-flange kanye ne-engeli kuklanyelwe ukunciphisa ukungqubuzana ngesikhathi sokujika ngenkathi kugcinwa imingcele emihle eceleni

Iphrothokholi Yokwelapha Ukushisa Okuhlukile:
I-roller idlula enkambisweni yokuqinisa i-induction elawulwayo edala iphrofayili yokuqina ehlelekile:

4.2 Ukucushwa kwe-Shaft Metallurgy kanye ne-Bearing

I-shaft engashintshi kanye nesistimu yokuthwala ejikelezayo kumele ivumelane nokunyakaza okuqhubekayo kokujikeleza ngenkathi isekela imithwalo yemisebe eshintshashintshayo ngesikhathi sokumba, ukuhamba, kanye nokusebenza kokujika.

Ubunjiniyela be-Shaft:

• Yenziwe ngensimbi ye-alloy engu-40Cr noma engu-20CrMnTi enamandla amakhulu
• Amajenali okuthwala aqoqwa ngokunemba kuze kube sekupheleni kobuso okufana nesibuko (Ra ≤ 0.4 μm) ukuze kuncishiswe ukungqubuzana ezindaweni zokuvala
• Izindawo eziqiniswe yi-induction noma ezine-plasma-nitride zimelana nokugqwala okubangelwa ukuthintana okujikelezayo

Uhlelo Lokuthwala:

• Isebenzisa ama-roller bearings anemigqa emibili noma ama-bronze bushings aqinile, kuye ngokuthi hlobo luni lomndeni we-KM2503.
• Ama-bearings akhethwa ukuze kuthuthukiswe izilinganiso zomthwalo oguqukayo ezifanele isisindo sokusebenza se-PC1250 kanye nomjikelezo womsebenzi.
• Imikhono yesikhala esinembile iqinisekisa ukuhambisana kwangaphakathi okulungile kanye nokulayisha kusengaphambili, isusa ukudlala kwe-axial ngaphansi kwezimo zokusebenza

4.3 Ukwakhiwa Kokuvala Okuthuthukisiwe

Into eyodwa ebaluleke kakhulu enquma impilo yenkonzo ye-carrier roller ekusetshenzisweni kwezimayini ubuqotho besistimu yayo yokuvala. Ukungena kokungcola—ikakhulukazi okuvela esihlabathini se-silica, i-ore ecoliwe, kanye nezinhlawulo zensimbi—kuyimbangela eyinhloko yokwehluleka kwezingxenye ezingaphansi kwemoto okungaphezu kuka-90%.

I-HELI CQCTRACK isebenzisa ukwakheka kokuvala okunezigaba eziningi, okuhambisana nokucindezela okwenzelwe ngqo izindawo ezisebenza kakhulu:

Umgodi ovalwe ngokuphelele ugcwaliswe kusengaphambili ngamafutha e-lithium-complex aqinile, aqinile futhi aqinile aqukethe izithasiselo zokugcoba eziqinile (i-molybdenum disulfide) zokuvikela ukugcotshwa komngcele ngaphansi kwengcindezi enkulu.

5. Amakhono Okukhiqiza: I-HELI CQCTRACK njengoMkhiqizi Womthombo

I-HELI Machinery Manufacturing Co., Ltd. (CQCTRACK) isebenza njengomkhiqizi ohlanganiswe ngokuqondile, ihlukanisa nabasabalalisi bezingxenye kanye nezinkampani zokuhweba ngokulawula okuqondile kulo lonke uchungechunge lwenani lokukhiqiza.

5.1 Ukwakhiwa Kokuhlanganiswa Okuqondile

5.2 Uhlaka Lokuqinisekisa Ikhwalithi
