Kune marudzi maviri eringingkukuvara, imwe kukuvara kwemujaho, uye imwe izino rakavhunika.Kukuvadzwa kwemujaho kunodarika 98%, saka kunaka kwemujaho chinhu chakakosha chinokanganisa hupenyu hwemujaho.ringing.Pakati pazvo, kuomarara kwemujaho, kuomarara kudzika kwemujaho, nhangemutange curvature radius uye kuonana kona ndizvo zvina zvakakosha zvinokanganisa kunaka kwemujaho.
1. Raceway kuoma
Kudzima kuomarara kweringingraceway ine simba guru pane yayo yakatemerwa static mutoro.Kana iyo yakatemerwa static mutoro iri 1 pa55HRC, hukama hunoenderana pakati peyakatemerwa static mutoro wekutakura uye kuoma kwemujaho unotevera:
| Raceway kuoma HRC | 60 | 59 | 58 | 57 | 56 | 55 | 53 | 50 |
| Rated static load | 1.53 | 1.39 | 1.29 | 1.16 | 1.05 | 1 | 0.82 | 0.58 |
Thekuurayakubva kuXZWDkuurayakambani mujaho kuoma kuri 55HRC ~ 62HRC.
2.Hudzamu hweakaomeswa layer yemujaho
Iyo inodiwa kudzika kweakaomeswa layer ndiyo vimbiso yekuti theringingraceway haina kupera.Apo iyokuurayainotakura mutoro wekunze, bhora resimbi uye nhangemutange inoshanduka kubva pakusangana kusvika pakubata pamusoro, uye nzvimbo yekubata inzvimbo yeelliptical.Pamusoro pekudzvinyirira kudzvinyirira, mujaho wemujaho unowanikwawo nekuveura kushushikana, uye iyo yakanyanya shear stress inoitika pakadzika 0.47a (iyo huru semi-axis yeiyo contact ellipse) pazasi pepamusoro, Ichi zvakare chikonzero nei yakaomeswa layer kudzika inotsanangurwa muyero zvichienderana nehupamhi hwebhora resimbi panzvimbo yedhayamita yeringing, uye iyo shoma yakavimbiswa kukosha inopihwa muyero.Iyo yakatemerwa static load C yebearing inoenderana nekudzika kweiyo yakaoma layer H0.908.Kana iyo yakaomeswa kudzika kwakadzika kunodiwa kuve 4mm ichingodzimwa kusvika 2.5mm, iyo inotakura static mutoro C ichaderedzwa kubva pa1 kusvika 0.65, mukana wekukuvara kunekuurayanekuda kwekuneta peeling kuchawedzerwa zvakanyanya.
Somuenzaniso, thekuurayamujaho layer kudzika013.35.1250 mujaho uri ≥ 3.5mm.
3.Curvature radius yemujaho
Rutivi rwemujaho (curvature radius) zvinoreva nhangemutange yenzira yemujaho muchikamu chakatwasuka.Iyo reshiyo t yeradius yemujaho kune radius yebhora resimbi zvakare inokanganisa zvakanyanya iyo yakatemerwa static mutoro uye kuneta hupenyu hwe.ringing.Kana t = 1.04, iyo yakatemerwa static mutoro uye hupenyu hwekuneta ndeye 1, uye hukama hunowirirana pakati peyakayerwa static mutoro uye kuneta hupenyu hweringinguye t iri sezvinotevera.
| Curvature ratio | 1.04 | 1.06 | 1.08 | 1.10 |
| Rated static load | 1 | 0.82 | 0.72 | 0.65 |
| Kuneta hupenyu | 1 | 0.59 | 0.43 | 0.33 |
Zvinogona kuonekwa kubva patafura iri pamusoro kuti yakakura iyo radius reshiyo, yakaderera iyo yakayerwa static mutoro uye hupfupi hupenyu hwesevhisi.
4.Raceway kuonana nekona
Iyo kona yekubata inoreva kona iri pakati pemutsara unobatanidza nzvimbo yekubata kwebhora resimbi pamujaho uye nepakati pebhora resimbi uye chikamu cheradial (yakatwasuka ndege)kuuraya.Iyo yakayerwa static mutoro C yeringinginoenderana nemutsara kune SINα, uye iyo yekutanga yekuona kona inowanzo 45 °.Apo iyokuurayaine gap, iyo chaiyo yekona yekubata ihombe pane yekutanga yekuona kona.Iyo gap yakakura, iyo yakakura iyo chaiyo yekusangana angle.Mukati meiyo gap renji inotsanangurwa neyakajairwa, inowanzowedzera ne2 ° ~ 10 °, ndiko kuti, iyo chaiyo yekusangana angle ichasvika 47 ° ~ 55 °, inova shanduko yakanaka yekutakura simba.Asi kana iyo yepakutanga yekuona kona uye gap yakakura, iyo chaiyo yekuona kona inodarika 60 °.Sezvo nzira yemujaho inopfeka, gaka rinowedzera kuwedzera uye iyo chaiyo yekusangana angle ichawedzerawo.Panguva ino, iyo contact ellipse inogona kudarika kumucheto kwemujaho., Simba chairo remujaho richave rakakwirira kudarika theoretical kuverengerwa kushushikana, izvo zvinozoita kuti kumucheto kwemujaho kudonha uyekuurayaachakundikana.
Semuenzaniso, iyo yekutanga yekuonana kona yekuuraya013.40.1250 is 45°.
Ndatenda nekuongorora chinyorwa ichi, kana uine chero mubvunzo pakuuraya mhete, ingonzwa wakasununguka kutibata nesu!
