Kukhala ndi Kutopa Kulephera: Momwe Rolling Contact Kupsinjika Kumabweretsera Ming'alu ndi Spalling

Kulephera kwa kutopa kumakhalabe chomwe chimayambitsa kuwonongeka kwanthawi yake, zomwe zimapangitsa kuti 60% yalephereka pamafakitale. Kugudubuza zinthu zokhala ndi mphete yamkati, mphete yakunja, zinthu zogudubuza (mipira kapena odzigudubuza), ndi khola-ntchito pansi pa cyclic loading, ndi zinthu zogudubuza mosalekeza kutumiza mphamvu pakati pa mphete.

Chifukwa chaching'ono kukhudzana m'dera pakati pa zinthu akugudubuzika ndi raceways, chifukwaKupanikizika kwa Hertzianndi okwera kwambiri, makamaka m'malo othamanga kwambiri kapena olemetsa kwambiri. Izi anaikira nkhawa chilengedwe kumabweretsakutopa maganizo, kuwoneka ngati kubowola pamwamba, ming'alu, ndipo pamapeto pake kuphulika.

Kodi Kutopa Kupanikizika N'kutani?

Kupsinjika kutopa kumatanthawuzakuwonongeka kwamapangidwe am'deralochifukwa cha kuchulukitsidwa mobwerezabwereza m'munsi mwa mphamvu yamphamvu kwambiri yazinthu. Pamene ambiri akuberekaZimakhalabe zopunduka, madera osawoneka bwino amakumana ndi kupindika kwa pulasitiki pakapita nthawi, kenako kumayambitsa kulephera. Ndondomekoyi nthawi zambiri imachitika m'magawo atatu opita patsogolo:

1. Microcrack Initiation

• Amapezeka pamtunda wapansi (0.1-0.3 mm pansi pa msewu wothamanga).

• Zomwe zimayambitsidwa ndi kupsinjika kwa cyclic pazovuta za microstructural.

2. Kufalikira kwa Mng'alu

• Ming'alu imakula pang'onopang'ono m'njira zomwe zimakhala zovuta kwambiri kumeta ubweya.

• Kutengera zolakwika zakuthupi ndi kagwiritsidwe ntchito kakutsegula.

3. Final Fracture

• Kuwonongeka kwa pamwamba kumawonekera ngatispalling or kubowola.

• Ming'alu ikafika pakukula kwambiri, zinthu zimachoka pamwamba.

Kuganizira Kutopa Kwa Magalimoto Amagetsi Olemera Kwambiri

In magalimoto akuluakulu (LGVs)ndimagalimoto onyamula katundu wolemera(ma HGV)-makamaka mitundu yamagetsi-kukana kutopa ndikofunikira kwambiri chifukwa cha:

• Mtundu Wambiri wa RPM: Ma motors amagetsi amagwira ntchito pamagulu othamanga kwambiri kuposa ma injini oyatsira moto, ndikuwonjezera kuchuluka kwa ma cyclic.

• Kutulutsa Kwapamwamba kwa Torque: Kutumiza kolemera kwa torque kumafuna mayendedwe owonjezera kutopa.

• Battery Weight Impact: Kuchuluka kowonjezera kwa mabatire oyendetsa kumabweretsa kupsinjika pazinthu za drivetrain, makamakama gudumu ndi ma mayendedwe amoto.

Zomwe Zimayambitsa Kupsinjika Maganizo

√ Kusinthana Katundu

Ma bearings mu machitidwe osinthika nthawi zonse amawonekera mosiyanasiyanama radial, axial, ndi kupindika katundu. Pamene zinthu zozungulira zimazungulira, kupsinjika kwa kulumikizana kumasintha mozungulira, ndikupanga kupsinjika kwakukulu pakapita nthawi.

√Zowonongeka Zakuthupi

Kuphatikizika, ming'alu yaying'ono, ndi voids mkati mwazinthu zonyamula zimatha kukhala ngatikupsinjika maganizo, kufulumizitsa kutopa kuyamba.

√Mafuta Osauka

Mafuta osakwanira kapena owonongeka amawonjezekakukangana ndi kutentha, kuchepetsa kutopa mphamvu ndi kufulumizitsa kuvala.

√Kuyika Molakwika

Kuyika molakwika, kukwanira molakwika, kapena kumangirira mopitilira muyeso pakukhazikitsa kungayambitse kupsinjika kosayembekezereka, kusokoneza magwiridwe antchito.

Kumvetsetsa ndikuchepetsa kutopa kwapang'onopang'ono ndikofunikira kuti mukhale ndi moyo wautali wantchito pamapulogalamu ovuta - makamaka magalimoto onyamula magetsi. Ngakhale kupita patsogolo kwazinthu ndi ukadaulo woyerekeza kwawonjezera kukana kutopa, koyenerakukhala ndi kusankha, kukhazikitsa, ndi kukonzaakadali ofunikira pakuchita bwino komanso kudalirika.
