Track Roller Tusaale Weyn leh oo la sameeyay Ilaalin Halkan ah si ay ku guulato Xumaanta Dheeraska

Sayniska Dharraaridda Isgaarsiinta Isgaarsiinta Horumariyaha Carruur track Xog

Sababtana Xaqiiqsiga Xaqiiqsiga Waa Muhiimadda Leh Qalabka Raadaha Raadinta Raadinta Dhulka carruurtanka

Hoose hawada xoogaa la'aan oo ah meeshaha dhagaysasho iyo sameynimo, qalabka raadaha waxay ku soo socdaan daboolitaanka la xaqiijiyey si kale 1,500 MPa. Xaqiiqsiga xaqiiqsiga shuqullada shuqullada shuqullada - xaqiiqsiga hore waxay ku dhaartaa biyaha badan iyo dhicitaanka hoose. Warbixin 2023 ayaa ogaaday in kordhinta jiritaanka sare 20% ku dhaafi frequency of replacement of track roller by 35% in quarry applications.

Sida Isgaarsiinta Ku Saara Jiritaanka Sare iyo Qalabka Qalabka

Ilaallooyinka xadgudbinta sameeya saayid martensitic (55–65 HRC) ku taal salka roolyaha, laakiin waxay iskudhufan tahay qalbiga dhexe oo kalooqday (30–40 HRC). Midoobida doolaa ah ka dhigaysa tijaabooyinkan:

• 40% si toosan ugu hor jeednaansho koronto kuwaas oo loo eepiyo roolyaha aan ilaalin karin
• 30% kordhinta jiritaanka inta lagu wanaalo hoosaadka marwaliba
• Dhaawacyada dhulka ku qoran oo ka hor yimaada furfurinta fureyso

Sarreefinta Xadgudbinta adoo isticmaalaya Ilaallooyinka Sarreefinta iyo Jarjaridda Hool-galinta Raacitaan

Ilaallooyinka ka dib marka xadgudbinta (150–300°C gudahood 2–4 saa) ku qoronto qalabka adoo beddeliyo 10–15% martensite oo ah martensite la ilaaliyey. Marka la geynayo jarjaridda habdhaafka ee 25–50°C/s, aragtidaas sameynaa:

• Xadgudbinta-toughness aabaynta saxda ah (55 HRC salka / 35 HRC qalbiga)
• Kala duwanaansho dhaawaca aabbaadka ah 40–60% ka yar kamaa ilbiriisiga oil quenching
• <0.1% kala duwanaansho buuxinta wakhtiga lacagta dhexdood

Dooro Ee Qaybaha Dhulka carruurtanka : Fulus Iyo Fulus Alloy-ka Waddada Kala Duwanaanshaha Caasimaha Qalabka

Waddidka Qalabka Iyo Tabaarakdooda 40CrMo, 42CrMo, Iyo Fuluhu Manganese

Fuluhu loo isticmaalayo rollers track waa inay dhaartahay xaaladaha dab aad u wayn. Marka lagu soo gaaro caasimaha qalabka, fuluha alloy-ka 40CrMo iyo 42CrMo waxay noqdaan tijaabooyinka la leeyahay sabiilka ay ku yaallaan chromium molybdenum. Kuwa tan waxay saamaysataan kala duwanaanshaha qalabka 15% ilaa 20% ka dib marka loo eego fuluhen carbon-ga ah, taasoo dhakhtar u ah gudaha qalabka. Midkasta, fuluha manganese, sida NM400, waxay bixisaa jabin si fiican marka la gooyo, gaadhitaanka xaqiiqsanaanta 350 HB. Laakiin, waxaa jira calaamo. Sidaas darteed, iyadoo ay ku jabinayaan socodalka, waxay noqon kartaa adag inta loo baadiyo marka la istcmaalo welding. Haddaba nasiib u eegneya sida fuluhaan kala duwan waxay muujiyaan yar-yar.

Qaaliyadda Abnaqlo: Kuwo, Isku dayninta Dheatu iyo Isku dayninta Tijilka ah ee Track Rollers

Kuwa Jidhka Wheel si loo helo Qaaliya iyo Xooliga Dheerka

Abnaqloka bilaabmaa kuwada qaybta gacanta (closed die forging) iyagoo isticmaalaya fululho sheekad ah sida 40Mn2 ama 50Mn. Jarriyaddu wuxuu shaqeynayaa boqortooyada kala duwan 1,100 digrii Celsius oo ka caansan, taas oo ka caawiya in la isku dhufto jiidhaha fululhuna, sidoo kale in lagu dhaafiisyo furfurkii dhexeedyada aan rabnimaha inay ka fog tahay. Marka jiidhaha si fiican loo siiyo heer sax ah, waxa laga saaraa in macawimihii muujinaysa ay noqdaan 12% ka weyn kaliya midabka loo sameeyey. Kan aad uga fekereysaa marka qaarkood inta badan ay u baahan yihiin inay daawasho koronto waaweyn, kadibna inay gaadhato 25 ton ama ka badan, iyagoo aan cadhadhin. Jidhka wheel-ka loo kuwaday waxa uu leeyahay kontrolla taniis weyn oo leh + ama - 0.5 millimeter. Kontrolladhan yar, laakiin muhimman, waxay ka ilaalinaysaa in xoolo laabto, taas oo sababi kartaa crack-ka dhismeeddada loo isticmaalayo maalin-gal ah durdurka iyo meelaha dhulka.

Abnaqdooyinka Pin: Helitaanka Jirka Gaarka ah Ku Qorista Quenching iyo Tempering

Track roller pins waxaa la quenching gareeyaa oil oo laabka dambena tempering sare (450–600°C) si ay tahayn taniis balansiyeedka jirka gaarka (58–62 HRC) iyo jirka ductility. Marwaliba meesha noocan ka dhigata in ay kala duwan tahay, halkaas oo ay leedahay qaybta Charpy impact toughness kamid ah 40 J markii -20°C. Iyadoo dambe in ay la fashilin doonaan ultrasonic testing si ay u hubiyaan in qaadka caawinaadda aysan ka weyn tahay 0.2%.

Surface Grinding iyo U bartida Dambe ee Aagga iyo Salka Weyn

CNC grinding machines ayaa gaaraa surface finishes ₺0.8 μm Ra, ka dhiman karta habdhiska friction heat wakhtiga la isticmaalayo. Isku-dhufashada amarada horizontal milling ayaa hubiyaan radial runout hoose 0.02 mm, taasoo xigmadda muhiimka ah ku dhisey in ay dhalisaa wear aan isku mid ahayn 37% wakhtiga la isticmaalayo high-speed. Fashilmaha dambe waxaa ku jira CMM validation of bore concentricity within 5 microns.

Dhibaatooyinka soo galay

Waa maxay muhiimadda loo yaqaanaa wear resistance? dhulka carruurtanka ?

Awooditaanka wajigiisu baa kamida ku qoran yahay kaarkaas sababtoo ah wuxuu si toos ah u saamaysaa dhererka wixii loo isticmaalo. Awooditaanka weyn wax u khasabda awooditaanka hore, ka dhigga inta badan ee jadwalka iyo in lagu hortago dhacdo kharashka gudaha waaweyn oo la iskaga fasaxay siinaysa meeqil iyo maamulka.

Sida kulaalinta xun ku saaraan karrarka awood u leh?

Kulaalka xun waxay abuuraan tarbisho faras martensitic-ka tarbishada karrka, kaas oo kordhaya awooditaanka dhagaysiga, dhererka jeedka, iyo in lagu daro horumarinta shimbirrada. Tanu wuxuu noqon karta tani jawaabaha sare iyo awood dheer ee kaarkaas.

Miyaan tijaabado laser-ka wanaagsaneyso kalaamiyada kale ee caadiga ah?

Tijaabado laser-ka waxay bixisaa heer gaar ah oo kalsooni, ka dhigta saamaynta jiqmaha, iyo helitaanka awood gaar ah oo ay ka weyn tahay kalaamiyada caadiga ah sida kulaalka induction-ka. Tanu wuxuu noqon karta tani awood sare iyo awooditaan koronteed ee karrarka.
