I-SANY SSY009115264 SY750 Track Bottom Roller Assembly-Umenzi wezixhobo ze-crawler excavator ezisebenza nzima-i-HELI(cqctrack)

1. Ukuchongwa kweCandelo kunye neNkcazelo yoMsebenzi

I-Track Bottom Roller Assembly (Inombolo yeCandelo le-OEM:SSY009115264) yinxalenye ephambili ethwala umthwalo ngaphakathi kwesakhiwo somkhondo ongezantsi we-excavator yemigodi enzima ye-SANY SY750. Yenziwe yi-HELI (CQCTRACK) njengendibano yokutshintsha eyenziwe ngobunjineli obuchanekileyo, le nxalenye—ekwabizwa ngokuba yi-roller esezantsi okanye i-track roller—ifakelwe ngqo kwisakhelo somkhondo kwaye yenza ujongano oluphambili loqhagamshelwano phakathi kobunzima obukhulu bomatshini kunye nekhonkco lomkhondo. Umsebenzi wayo ophambili kukuxhasa ubunzima bokusebenza komatshini ngelixa iququzelela intshukumo egudileyo yomkhondo kwiindawo ezinzima kakhulu.

2. Iimfuno eziphambili zendima yokusebenza kunye nokusebenza

Kwisixhobo esikwizinga le-SY750 (iitoni ezingama-75-85), i-roller esezantsi isebenza phantsi kweemeko ezinzima, nto leyo ebangela ukuba kubekho ubunjineli obugqwesileyo:

• Ukuthwala Umthwalo Oyintloko: Ixhasa ngokuthe ngqo ubunzima obungashukumiyo nobutshintshayo bomgxobhozo, idlulisela amandla okusabela komhlaba phezulu kwisakhelo somzila. Kufuneka imelane nemithwalo emikhulu yemitha ngexesha lokumba, ukuphakamisa, nokuhamba.
• Isikhokelo kunye nozinzo lweTrack Chain: Ibonelela ngendlela eqhubekayo neqinileyo yokuba iindibano zekhonkco zeTrack chain kunye nee-bushings zihambe phezu kwayo, igcina uzinzo olusecaleni kwaye ithintele ukuphuma kwesiporo phantsi koxinzelelo oluphezulu olusecaleni.
• Ukunciphisa Ukothuka Nokungcangcazela: Isebenza njengomgca wokuqala wokhuselo ekutsaleni imithwalo yempembelelo evela kumhlaba ongalinganiyo, iibhentshi zamatye, kunye neminye imiqobo, ikhusela yonke indawo engaphantsi kwesithuthi kunye nesakhiwo esingaphezulu kumonakalo obangelwa kukothuka kunye nokudinwa komqhubi.
• Ulawulo lweNgcoliso: Uyilo lwayo kunye nenkqubo yokutywina kufuneka zikhuphe ngamandla izinto ezirhabaxa (i-silica, uthuli lwesinyithi) kunye nokufuma, ezizezona zinto ziphambili ezibangela ukuguguleka kwangethuba kunye nokungaphumeleli kweebheringi kwiindawo zemigodi.

3. Iinkcukacha zoBunjineli boLwakhiwo oluneenkcukacha kunye neNkcukacha zeMpahla

Inkqubo yokuvelisa ye-HELI yale ndibano isebenzisa iinkcukacha ezinzima ezenzelwe ukusetyenziswa kwemigodi:

• Umzimba weRoller kunye neeFlanges:
  • Izinto: Zenziwe ngentsimbi ene-alloy ephezulu, eyongezwe nge-boron (umz., 50B okanye efanayo). Oku kubonelela ngokulinganisela okufanelekileyo kokuqina, ukuqina, kunye nokumelana nokuguguleka.
  • Unyango Lobushushu: Umphezulu ongaphandle obalekayo kunye neeflanges ziqiniswa kakhulu nge-carburizing, kulandele i-tempering. Oku kudala umphezulu ogugileyo kakhulu (HRC 58-63) onobunzulu obaneleyo bokunyamezela iminyaka yokuthintana okurhabaxa, oxhaswa yi-core eqinileyo, efunxa ukuthuthumela.
  • Umatshini: Umatshini wokugaya we-CNC uqinisekisa ukuqina okuchanekileyo, iprofayili yeflange, kunye nokuthembeka komphezulu wokutywina. Ukuphakama kunye nobukhulu beflange zenzelwe ukuqulatha uthotho oluthile lwethrekhi olusetyenziswa kwi-SY750.
• Inkqubo yeShaft kunye neBearing:
  • Ishaft: Yenziwe ngentsimbi ye-alloy ecinyiweyo neqinisiweyo (42CrMo4). Iijenali ze-bearing ziyacocwa ngocoselelo, kwaye zihlala ziphathwa nge-induction hardening okanye i-plasma nitriding ukuze zixhathise ukugqwala kunye nokuguga.
  • Uqwalaselo lweeBheri: Isebenzisa iibheringi zerola ezinkulu kakhulu, ezinemigca emibini okanye iibheringi zerola ezingqukuva ezinemilinganiselo yomthwalo oguqukayo. Ezi zilayishwa kwangaphambili kwaye zilungiselelwe ukusingatha amandla amakhulu ajikeleze iindawo ezininzi ze-excavator yemigodi.
  • Ukufakelwa: I-shaft idla ngokuba yi-press-fit okanye i-bolted flange design, iqiniswe ngokukhuselekileyo ngaphakathi komzimba we-roller ukuthintela ukujikeleza nokuqinisekisa ukuba yonke i-torque idluliselwa kwiibheringi.
• Itekhnoloji yokutywina ePhambili:
  • Isitywino esinee-multilayer, uhlobo lwekhatriji siqhelekile. Le nkqubo idla ngokuhlanganisa:
    1. Isiciko semilebe esiphambili esenziwe nge-hydrogenated nitrile (HNBR) sokumelana nobushushu obuphezulu kunye nokumelana neekhemikhali.
    2. Itywina yobuso yesibini edadayo okanye i-labyrinth yesinyithi ukuya kwisinyithi.
    3. Isilingi sangaphandle kunye nomlebe wothuli ukuze kuthintelwe inkunkuma enkulu.
  • Umngxuma ovalekileyo ugcwele igrisi ye-lithium complex ene-viscosity ephezulu, ezinzileyo neyomeleleyo equlethe izongezo ze-lubricant eziqinileyo (umz., i-molybdenum disulfide) zokukhusela ukuthambisa umda.
• Uyilo lokuthambisa nokulungisa: Lunegrisi enzima efakelwa ukugcwalisa kwakhona ngexesha elicwangcisiweyo. Ezinye iindlela zoyilo zinokubandakanya ivalvu yokukhulula igrisi ukuthintela umonakalo wetywina ngenxa yokuxinzelelwa kakhulu.

4. Iprofayili yoMveliso: Amandla e-HELI (CQCTRACK)

Imveliso ye-HELI yale nxalenye isebenzisa ubuchule bayo kwiindawo ezingaphantsi kwesithuthi esikhulu kakhulu:

• Inkqubo yokudibanisa ngokuthe nkqo: Ulawulo olupheleleyo ukusuka ekukhetheni i-alloy yentsimbi kunye ne-closed-die forging, ukuya kwi-machining, thermal processing, kunye ne-assembly.
• Ukulungisa nokutshisa: Kusebenzisa ii-press ze-forging ezinkulu ukuze kuphunyezwe ukuhamba kakuhle kweenkozo. Ii-oven ze-carburizing ezilawulwa yikhompyutha kunye nemigca yokushisa iqinisekisa ukuqina kwe-case okuhlala kufana nokunzulu.
• Imigaqo yoMgangatho noVavanyo:
  • Isiqinisekiso sezinto: Ukulandeleka ngokupheleleyo ngeengxelo zovavanyo lweekhemikhali nolwemishini.
  • Uvavanyo Olungonakalisiyo (NDT): Ukuhlolwa kwe-dye penetrant (DPI) okanye ukuhlolwa kwe-magnetic particle (MPI) yazo zonke iindawo ezibalulekileyo emva kokwenziwa kunye nokufakelwa.
  • Ukuqinisekiswa koBume: Ukuhlolwa koMatshini woKulinganisa oQokelelweyo (i-CMM) wejiyometri yokugqibela.
  • Uvavanyo Lokusebenza: Uvavanyo lwe-torque ejikelezayo kunye novavanyo loxinzelelo lwe-seal ngokusekelwe kwisampulu ukuqinisekisa ukuthembeka kwendibano.

5. Ulwazi malunga nokusetyenziswa, ukuhambelana kunye neenkonzo

• Ukusetyenziswa kweModeli ePhambili: I-SANY SY750 Crawler Excavator (Uqwalaselo lweMigodi).
• Ukuhlanganiswa kweNkqubo: Iiyunithi ezininzi zifakelwe ecaleni kweflengi esezantsi yesakhelo sendlela, zixhasa ngokuthe ngqo umtya ongezantsi wetsheyini yendlela.
• Ubomi bokunxiba kunye nokuhlolwa: Ubomi benkonzo buyimilinganiselo ebalulekileyo yeendleko ngeyure. Ukuguguleka kulinganiswa kububanzi bangaphandle berola kunye nobukhulu beflange. Ukuhlolwa rhoqo kokuvuza kwesitywino, iipateni zokuguguleka ezingaqhelekanga, okanye ukulahleka kokujikeleza kubalulekile.
• Izikhokelo Zokutshintshwa: Ngenxa yemeko yokusebenza enzima, iirola ezisezantsi zihlala zitshintshwa ngokweeseti kwicala ngalinye. Ukuze kubekho ubomi obufanelekileyo bokuhamba kunye nokusebenza kakuhle, ukutshintshwa kwazo kufuneka kuhambelane nemeko yokuguguleka kwetsheyini yetrekhi, i-sprocket, kunye ne-idler ukuthintela ukuguguleka okukhawulezileyo kwiindawo ezintsha.
• Eyona ndlela ilungileyo yokusebenza: Ukugcina uxinezeleko olufanelekileyo lomzila kunye nokuphepha ukuhamba rhoqo kwilitye elibukhali nelinamandla kubalulekile ekwandiseni ubomi bokuqengqeleka.
