Thechodulira cha njanjindi chimodzi mwa zinthu zolemera kwambiri zomwe zili mu galimoto yosungiramo zinthu zakale kapena bulldozer.

Mosiyana ndi zida zina zambiri zoyendera pansi pa galimoto, ma track rollers amanyamula gawo lalikulu la kulemera kwa makinawo pamene akugubuduzika mosalekeza motsutsana ndi unyolo wa track.

Onjezani matope, madzi, mchenga, miyala ndi nthaka yosafanana pa equation, ndipo mikhalidwe yogwirira ntchito idzakhala yovuta kwambiri.

Ichi ndichifukwa chake kuwonongeka kwa roller yothamanga msanga sikumachitika kawirikawiri chifukwa cha chinthu chimodzi chokha. Kusankha zinthu, kutentha, mphamvu ya kapangidwe kake, ndi kapangidwe ka mkati mwa bere zonse zimakhudza nthawi yomwe roller ingagwire ntchito m'munda.

1. Thupi la Roller la 42CrMo lopangidwa kuti ligwiritsidwe ntchito molimbika

Pa thupi lozungulira, timagwiritsa ntchitoChitsulo chopangidwa ndi 42CrMom'malo mwa zinthu wamba zopangidwa ndi chitsulo.

Thupi lozungulira limayamba kuziziritsa ndi kutenthetsa kuti likhale lolimba, ndipo kulimba kwake kumapitirira pamwamba.HRC 32.

Kenako malo ogwirira ntchito amalimba kutiHRC 52–60, yokhala ndi wosanjikiza wolimba wa pafupifupi6–12 mm.

Chigawo cholimba kwambiri ichi n'chofunika kwambiri makamaka pa makina omwe amagwira ntchito molemera.

Chogudubuza cha track sichimawonongeka pamwamba pake pokha. Kugudubuza kosalekeza motsutsana ndi track, kuphatikiza miyala yolimba ndi tinthu tomwe timagunda, kumatha kutha pang'onopang'ono pamalo ogwirira ntchito.

Cholimba cholamulidwa bwino chimathandiza kuti chozungulira chikhalebe cholimba kwa nthawi yayitali komanso chimachepetsa chiopsezo cha kusweka kapena kusweka kwa malo msanga.

Kwa makina olemera okumba zinthu, ma bulldozer ndi makina ena omwe amagwira ntchito pamalo ovuta, kusiyana kumeneku kungakhale kwakukulu pakapita nthawi yayitali yogwira ntchito.

2. Shaft Yolimba Kwambiri Yonyamula Katundu Wolemera Ndi Mphamvu Yobwerezabwereza

Mphepete mwa shaft imakumana ndi vuto lina.

Pa nthawi yogwira ntchito, chodulira cha track roller sichimangomva kukweza kuchokera pamakina okha komanso mphamvu yobwerezabwereza yomwe imachitika chifukwa chotembenuka, kukwera mapiri komanso kuyenda m'malo osalinganika.

Timagwiritsa ntchitoChitsulo cha 42CrMokwa shaft.

Pambuyo pozimitsa ndi kutenthetsa, kuuma kwapakati kumasungidwa pamwambaHRC 28, pomwe malo ogwirira ntchito ali olimba kutiHRC 52–60.

Gawo lolimba limayendetsedwa pafupifupi3–5 mm.

Kuphatikiza uku kwapangidwa kuti kugwirizane ndi zofunikira ziwiri:

Kukana kuvala pamwamba + Kulimba kwapakati

Malo olimba amathandiza kuchepetsa kuwonongeka pakati pa shaft ndi bearing, pomwe pakati pa chitsulo cholimba chimapereka kukana bwino kupindika ndi kugwedezeka.

Pa ntchito zolemera, kulinganiza kumeneku n'kofunika. Mpeni wolimba kwambiri koma wopanda kulimba ukhoza kukhala pachiwopsezo cholephera chifukwa cha kugwedezeka, pomwe kuuma kosakwanira pamwamba kungathandize kuti pakhale kuwonongeka mwachangu.

3. Zophimba ndi mipando yopangidwa kuti ikhale yolimba bwino

Thupi la roller silo lokhalo lomwe limafunikira.

Thezophimba kumapeto ndi mipando ya shaftamapangidwa kuchokera kuchitsulo chopangidwa ndi # 45ndipo amalandira chithandizo chozimitsa ndi chotenthetsera.

Poyerekeza ndi zida zachikhalidwe zopangidwa ndi chitsulo, kapangidwe kake kopangidwa ndi chitsulo kamapereka umphumphu wolimba kwambiri pakugwira ntchito molimbika.

Ma track rollers nthawi zambiri amakumana ndi miyala, nthaka yosalinganika komanso katundu wogunda mwadzidzidzi.

Kapangidwe kolimba ka kumapeto kumathandiza kuchepetsa chiopsezo cha kusinthika kapena kusweka pansi pa mikhalidwe iyi.

Zimathandizanso kuteteza njira yothira mafuta mkati.

Chozungulira chikapanga ming'alu kapena kutseka bwino mozungulira chimangocho, matope ndi madzi zimatha kulowa mkati. Dongosolo lopaka mafuta likaipitsidwa, kuwonongeka kwa mabearing ndi shaft kumatha kufulumira kwambiri.

Choncho mphamvu ya kapangidwe kake ndi chitetezo chotseka zimagwira ntchito limodzi.

4. Bimetal Bushings kuti Igwire Ntchito Yolimba Mosalekeza

Dongosolo lamkati la zotengera ndi gawo lina lomwe limakhudza mwachindunji kudalirika kwa roller ya track.

Ma track rollers athu amagwiritsa ntchitoma bushing a bimetal okhala ndi wosanjikiza wamkuwa woposa 0.7 mm mbali imodzi, pamodzi ndimphete zoyera zamkuwa.

Kapangidwe ka bere lopangidwa ndi mkuwa kamapereka mawonekedwe abwino onyamula katundu komanso ochepetsa kukangana.

Izi ndizofunikira kwambiri kwa makina omwe amagwira ntchito mosalekeza pansi pa katundu wambiri.

Cholinga chake ndi kusunga kulumikizana kokhazikika pakati pa shaft ndi bushing pomwe kuchepetsa kukangana ndi kupanga kutentha.

Ndi mafuta oyenera komanso kukonza bwino, kapangidwe kake kamathandiza kuchepetsa chiopsezo chakugwidwa kwa shaft ndi kulephera kwa bushingpanthawi yogwira ntchito kwa nthawi yayitali.

Yomangidwa Mogwirizana ndi Mikhalidwe Yomwe Imalepheretsa Ma Track Rollers Kutuluka

Chozungulira cha track chingawoneke ngati chitsulo chosavuta.

M'malo mwake, imagwira ntchito pakukumana ndi zinthu zingapo zovuta:

• Kulemera kwa makina olemera
• Kulumikizana kosalekeza
• Mchenga ndi miyala yolimba
• Kuipitsidwa ndi matope ndi madzi
• Zotsatira kuchokera ku malo osalinganika
• Kutembenuza ndi kukwera katundu
• Mphamvu yobwerezabwereza ndi kugwedezeka

Ndicho chifukwa chake sitimaona kupanga ma track roller ngati nkhani yongopangitsa kuti roller ikhale yovuta.

Kapangidwe kake kayenera kulinganizidwa:

Mphamvu Zazinthu → Kutentha → Kukana Kuvala → Kulimba Kwa Kapangidwe → Kugwira Ntchito

Kuchokera ku forgedThupi la roller ndi shaft ya 42CrMoKu malo ogwirira ntchito olimba, zigawo zomangira ndi zitsulo za bimetal zopangidwa ndi mkuwa, gawo lililonse limapangidwa motsatira momwe galimoto yonyamuliramo imagwirira ntchito.

Chifukwa chakuti choyimitsa njanji chikalephera kugwira ntchito msanga, mtengo wake sumangokhala wosintha choyimitsa chimodzi.

Kuwonongeka kwina kwa msewu, nthawi yogwira ntchito kwa makina komanso kukonza galimoto isanakwane kungapangitse kuti ndalama zenizeni zikhale zokwera kwambiri.

Chogudubuza chabwino cha track si chovuta chabe, koma chingakhale chodalirika ngakhale chitakhala cholemera, chogundana komanso chokwezeka kwa nthawi yayitali.
