Chii chinonzi static load rating uye dynamic load rating yebearing?

 

Patinobvunza nezvekuberekamodhi, tinowanzoona sarudzo mbiri, Cr naCor, Cr zvinoreva mutoro unoshanduka wekutakura, Cor zvinoreva mutoro unoshanduka wekutakura. Saka chii chinonzi static load rating uye dynamic load rating yebearing? Ndeupi hukama nemusiyano uripo pakati pezviviri izvi?

Maparamita matatu anonyanya kushandiswa mukugadzira mabheyaringi anotenderera ndeaya: mutoro weCr (radial) kana Ca (axial) unosangana nezvinodiwa zvehupenyu hwakati hwekupera simba; Simba reCor (radial) kana Coa (axial) rinosangana nezvinodiwa zvesimba restatic uye kumhanya kwekupedzisira Nhamba, iyo inodzora kupfeka kwemabheyaringi.

 

Chii chinonzikuberekachiyero chemutoro usingachinji?

 

Chiyero chikuru chemutoro usingachinji we rolling bearings (radial Cor, axial Coa) chinoreva mutoro wekufungidzira we radial kana mutoro wepakati we axial static wakaenzana nemutoro wepamusoro we bearings kana imwe contact stress inokonzerwa nekumanikidzwa kwe contact pakati pe contact element ne raceway.

 

Kune mabheyaringi eradial, mutoro wakaganhurirwa unoreva mutoro weradial, weradial thrust bearing (angular contact ball bearing) unoreva chikamu cheradial chemutoro chinotakura nzira yemujaho muhafu yeringi yebheringi, uye wethrust bearing, unoreva mutoro wepakati weaxial.

 

Kureva kuti, radial basic static load rating uye axial basic static load rating yebearing zvinoreva mutoro mukuru unogona kutakura bearing kana iri static kana ichitenderera.

 

Kukwanisa kutakura mutoro kwemabheyaringi ebhora remugero wakadzika pakumira kana kutenderera zvishoma nezvishoma (kumhanya n≤10r/min) kunoongororwa semutoro usingachinji.

 

Chii chinonzikuberekachiyero chemutoro chinoshanduka?

 

Kuyera simba rekutakura zvinhu (bearing dynamic load rating) kunoreva kuti: bereing rinotenderera rinogona kutakura mutoro we radial unogara uripo (constant axial load), pasi pesimba rehupenyu hwe 100W rpm, mutoro we simba rekutakura zvinhu (basic rated dynamic load) unoratidza kugona kwebereing kurwisa kuneta kwe rolling. Kuyera simba rekutakura zvinhu (dynamic load rating) kwema radial bearings nema thrust bearings kunozivikanwawo se radial basic dynamic load rating uye axial basic dynamic load rating, izvo zvinoratidzwa neCr neCa.

 

Kugona kwekutakura mutoro kwemabhora emugero panguva yekutenderera (speed n>10r/mim) ndiwo mutoro wepakutanga une dynamic load.

 

Sei mutoro wesimba wakayerwa webheyaringi wakakura kupfuura mutoro usingachinji wakayerwa?

 

Mutoro wesimba wakayerwa unoreva mutoro uri pabearing kana hupenyu hwakayerwa huri 1 miriyoni rpm. Mutoro wesimba wakayerwa unoreva kubatana kuripo pakati pechinhu chinotenderera neringi raceway iyo inonyanya kuremedzwa kana bearing yakamira, uye huwandu hwekushanduka-shanduka kwechigarire kwechinhu chinotenderera neringi raceway i1/10,000 yedhayamita yechinhu chinotenderera.

 

Pane hukama hwakati pakati pehupenyu hwebasa rebheyaringi nemutoro wakayerwa webheyaringi, saka mumamiriro api ezvinhu atinosarudza beyaringi nemutoro wakayerwa webheyaringi? Pfungwa huru ndedzinotevera:

 

Cherechedza: Mune zvimwe zviitiko, saizi yebheyaringi inofanira kusarudzwa nechiyero chemutoro usingachinji (chinotsanangurwa seCo kuti zvive nyore kutsanangura) pane hupenyu hwebheyaringi.

 

1. Pasi pechiito chemutoro unoenderera mberi kana unopindirana, faniro yacho haichinji.

 

2. Pasi pemutoro, bearing inongoita oscillation inononoka kana kufamba kunogadziriswa.

 

3. Pasi pemutoro, kumhanya kwebearing kwakaderera zvikuru (pasi pegumi rema revolutions paminiti) uye kunoda hupenyu hupfupi chete. Kunyanya, muchiitiko ichi, kune mutoro wakaenzana P, chiyero chebasic dynamic load C chinodiwa chakaderera zvikuru zvichienderana nehupenyu, kuitira kuti bearing yakasarudzwa iwedzere zvakanyanya mukuita.

 

4. Pamusoro pemutoro wekushanda wakajairika, inodawo kutakura mutoro unorema kwazvo, uye bearing iri kutenderera.

 

Muzviitiko izvi zvese, mutoro unogona kutsungirira bearing hautsamiri pakuneta kwechinhu chacho, asi padanho rekushanduka kusingaperi kwenzira yemujaho kunokonzerwa nemutoro wacho.
