Kubviswa kwebheyaringi neaxial

 

Zvinonzi kuberekaclearance inoreva huwandu hwekufamba kanakuberekaHaina kuiswa mugomba kana mubearing housing, ichigadzirisa divi rimwe remhete yemukati kana mhete yekunze, uye yobva yaita kuti divi risina kugadzika rifambe nerutivi rwekutenderera kana kuti nerutivi rwekutenderera. Zvichienderana negwara rekufamba, inogona kukamurwa kuita nzvimbo yekumira nerutivi uye nzvimbo yekumira nerutivi rwekutenderera.

Saizi yenzvimbo inobviswa (inonzi nzvimbo inobviswa) panguva yekushanda ine chekuita nehupenyu hwekuneta, kukwira kwetembiricha, ruzha, kudedera nezvimwe zvinhu zvebheyaringi.

Pakuyera nzvimbo yebearing, ndiyo inonzi bearing clearance, iyo inoreva huwandu hwekufamba kana bearing isina kuiswa mushaft kana bearing housing, ichigadzirisa divi rimwe remhete yemukati kana yekunze, uye yobva yaita kuti divi risina kugadzika rifambe ne radially kana axial. Zvichienderana negwara rekufamba, inogona kukamurwa kuita radial clearance uye axial clearance.

Saizi yenzvimbo inobviswa (inonzi nzvimbo inobviswa) panguva yekushanda ine chekuita nehupenyu hwekuneta, kukwira kwetembiricha, ruzha, kudedera nezvimwe zvinhu zvebheyaringi.

Pakuyera nzvimbo yekubereka, mutoro wekuyera wakatarwa unowanzo shandiswa pabheyaringi kuti uwane kukosha kwakayerwa kwakasimba.

Nekuda kweizvozvo, kukosha kwakayerwa kwakakura kupfuura clearance chaiyo (inozivikanwa se theoretical clearance), kureva kuti huwandu hwe elastic deformation nekuda kwemutoro wakayerwa hunowedzerwa.

Zvisinei, kana iri roller bearings, elastic deformation iyi haina basa nekuda kwehuwandu hwayo hudiki.

Kubviswa kwemukati kwebheyaringi isati yaiswa kunowanzo ratidzwa maererano nekubviswa kwedzidziso.

Sarudzo yemvumo

Kubviswa kwechinhu mushure mekubvisa huwandu hwekuwedzera kana kupfupika kweringi nekuda kwekupindirana kwechinhu kana bearing yakaiswa pamugodhi kana muhombe kubva panzvimbo yekubvisa chinhu inonzi "mounting clearance".

 

Kubviswa kwechinhu mushure mekuwedzera kana kubvisa musiyano wehukuru nekuda kwekusiyana kwekupisa mukati mebearing kunonzi "effective clearance".

Bearing inoiswa ne clearance kana yakaiswa pasi pemutoro wakasiyana nemakanika, kureva kuti, clearance inoshanda inowedzerwa kune elastic deformation inokonzerwa nemutoro we bearing, saka inonzi "working clearance".　

 

Kana nzvimbo yekushanda iri negative zvishoma, nguva yekuneta yebearing ndiyo yakareba kupfuura dzose, asi nekuwedzera kwenzvimbo yekushanda iri negative, nguva yekuneta inoderera zvakanyanya. Saka, pakusarudza nzvimbo yekushanda iri negative, zvinokurudzirwa kuti nzvimbo yekushanda ive zero kana kuti yakanaka zvishoma.

Pamusoro pezvo, kana zvichidikanwa kuvandudza kuomarara kwebearing kana kuderedza ruzha, nzvimbo yekushanda inofanira kunge isina kunaka zvakanyanya, uye kana tembiricha yebearing yakwira zvakanyanya, nzvimbo yekushanda inofanira kunge yakanaka zvakanyanya, nezvimwewo, uye ongororo chaiyo inofanira kuitwa zvichienderana nemamiriro ekushandisa.

 

Pfungwa yekureruka mumabheyaringi anotenderera

1. Kubvumidzwa kwekutanga

Kubviswa kwechinhu chiri muchimiro chefree state usati waisa bearing. Kubviswa kwechinhu pakutanga kunotsanangurwa nekugadzirisa uye kuunganidza kwefekitori yekugadzira.

 

2. Kuiswa kwenzvimbo yekubvumidza

Inonziwo nzvimbo yekuberekesa, inova nzvimbo yekuberekesa kana chigaro chebheyaringi, shaft nechigaro chebheyaringi zvaiswa asi zvisati zvashanda. Nekuda kwekukanganiswa kwekuiswa, kungave rin'i yemukati yakakurisa, rin'i yekunze yakaderedzwa, kana zvese zviri zviviri, nzvimbo yekuberekesa idiki pane nzvimbo yekutanga yekuberekesa.

 

3. Chibvumirano chebasa

Kana bearing iri kushanda, kukwira kwetembiricha yemhete yemukati ndiko kwakanyanya, uye kuwedzera kwekupisa ndiko kwakanyanya, zvekuti bearing clearance inoderedzwa; Panguva imwe chete, nekuda kwemutoro, elastic deformation inoitika panosangana chinhu chinotenderera ne raceway, izvo zvinowedzera bearing clearance. Kana bearing clearance yekushanda iri yakakura kana kuti diki pane installation clearance zvinoenderana nemhedzisiro yezvinhu zviviri izvi.
