Kutakura Kuneta Kukundikana: Sei Rolling Kusangana Stress Inotungamira Kukutsemuka uye Spalling

Kutadza kuneta kunoramba kuri iko kuri kukonzera kukuvara kusati kwasvika, kunokonzeresa pamusoro pe60% yekukundikana mumaindasitiri ekushandisa. Rolling element bearings-inosanganisira mhete yemukati, mhete yekunze, inotenderedza zvinhu (mabhora kana rollers), uye keji-inoshanda pasi pe cyclic kurodha, ine zvinhu zvinotenderedza zvinoramba zvichiendesa masimba pakati pezvindori.

Nekuda kwenzvimbo diki yekubatana pakati pezvinhu zvinotenderedza uye mijaho, zvinogumaHertzian kuonana kunetsekayakakwira zvakanyanya, kunyanya pasi pekumhanya-mhanya kana kunorema-kuremerwa mamiriro. Iyi yakanyanya kushushikana nharaunda inotungamira kunestress kuneta, ichitaridza sekupindika kwepamusoro, kutsemuka, uye pakupedzisira kuparuka.

Chii Chinonzi Stress Kuneta?

Kushungurudzika kuneta kunorevalocalized structural damagezvichikonzerwa nekudzokororwa cyclic kurodha pazasi pezvinhu zvekupedzisira tensile simba. Nepo iyo yakawanda yekuberekainoramba yakaremara elastically, microscopic zones inosangana nepurasitiki deformation nekufamba kwenguva, pakupedzisira inotanga kutadza. Iyo nzira inowanzoitika mumatanho matatu anofambira mberi:

1. Microcrack Initiation

• Inowanikwa pamazinga epasi (0.1-0.3 mm pazasi pemujaho wepamusoro).

• Inokonzerwa ne cyclic stress concentrations pa microstructural imperfections.

2. Crack Propagation

• Mitswe inokura zvishoma nezvishoma munzira dzekunyanya kushushikana kweshear.

• Kupesvedzerwa nekuremara kwezvinhu uye mashandiro ekurodha matenderera.

3. Kuputsika Kwekupedzisira

• Kukuvadzwa kwepamusoro kunoonekwa sespalling or pitting.

• Kamwe makatsemuka asvika pakukura kwakakosha, zvinhu zvinobvisa kubva pamusoro.

Kuneta Kufunga kune Heavy-Duty Magetsi Mota

In motokari huru dzinotakura zvinhu (LGVs)uyemotokari dzinotakura zvinhu(HGVs)-kunyanya magetsi akasiyana-kuneta kuramba kunotonyanya kukosha nekuda kwe:

• Yakakura RPM Range: Mota dzemagetsi dzinoshanda pamabhendi akafararira kupfuura enjini dzinopisa, dzichiwedzera cyclic kurodha ma frequency.

• Yakakwira Torque Output: Inorema torque kutapurirana kunoda mabheri ane simba rakawedzera kuneta.

• Battery Weight Impact: Iyo yakawedzerwa yakawanda yemabhatiri ekudhonza inosimudza kushushikana pane drivetrain zvikamu, kunyanyavhiri nemabhengi emota.

Vanonyanya Kubatsira Kushungurudzika Kuneta

√ Alternating Loads

Bearings mune dynamic masisitimu anogara achiratidzwa kune akasiyanaradial, axial, uye inokotama mitoro. Sezvo zvinhu zvinotenderera zvinotenderera, kusangana nekushushikana kunoshanduka kutenderera, zvichigadzira kushushikana kwakanyanya nekufamba kwenguva.

√Material Defects

Inclusions, micro-cracks, uye voids mukati mekutakura zvinhu zvinogona kuita sestress concentrators, kukurumidza kuneta kutanga.

√Murombo Lubrication

Lubrication isina kukwana kana yakaderedzwa inowedzerakukakavara uye kupisa, kuderedza simba rekuneta uye kukurumidza kupfeka.

√Kuiswa kusina kunaka

Kusarongeka, kukwana kwakashata, kana kuomesa zvakanyanya panguva yekuisa kunogona kuunza kushushikana kusingatarisirwe, kukanganisa kuita basa.

Kunzwisisa uye kuderedza kushushikana kuneta kwakakosha pakuchengetedza hupenyu hurefu hwesevhisi mukukumbira-kunyanya mota dzemagetsi dzinorema. Nepo kufambira mberi kwezvinhu uye tekinoroji yekunyepedzera kwakawedzera kuneta kuramba, zvakakodzerakutakura kusarudzwa, kuiswa, uye kugadzirisazvichiri zvakakosha pakuita uye kuvimbika.
