Iyozvakanakira nezvayakaipira zvesimba guru remhepo

 

TMhando huru dzemabheyaringi espindle anoshandiswa pakugadzira maturbine emhepo e megawatt ndeaya: dhizaini yemabheyaringi e3-point bearing uye dhizaini yemabheyaringi e2-point bearing,Ndapota tarisa pazasiazvakanakira nekuipira kwebearingchimiro

 

Mabheyaringi edenderedzwa + mabheyaringi edenderedzwa

Zvakanakira ndezvekuti hapana mutoro unoshanda pabhokisi remagiya, ukuwo uchivimba neruoko rwekutenderera kuti rutsungirire kukanganisika kushoma, uye kugadzirwa kwacho kuri nyore.

 

Zvakashata ndeizvi:

1) Nzvimbo yepakati yakakura, uye nzvimbo yehub mudivi repakati haina kunaka;

2) Hapana preload pa main bearing, uye axial displacement yakakura mushure mekutakurwa, uye panguva imwe chete, nekuda kwekushaikwa preload, roller imwe chete inogona kusatenderera, izvo zvinotungamira mukutsvedza, izvo zvinoburitsa mutoro mukuru kwazvo uye zvinokanganisa hupenyu hwebearing;

3) Saizi yemubato idiki, uye simba remutoro pamubato rakakura.

 

Mabheyaringi anotenderera akatenderera + mabheyaringi eroller ane cylindrical

Zvakanakira zvekugadzirwa kwebheyaringi iyi ndezvekuti hapana mutoro unoshanda pabhokisi remagiya, ukuwo uchivimba neruoko rwekutenderera kuti rutsungirire kukanganisika kushoma, uye kuungana kuri nyore.

 

IyoZvakashata ndeizvi:

1) Nzvimbo yepakati yakakura, uye nzvimbo yehub mudivi repakati haina kunaka;

2) Hapana preload pa main bearing, uye axial displacement yakakura mushure mekutakurwa, uye panguva imwe chete, nekuda kwekushaikwa preload, roller imwe chete inogona kusatenderera, izvo zvinotungamira mukutsvedza, izvo zvinoburitsa mutoro mukuru kwazvo uye zvinokanganisa hupenyu hwebearing;

3) Saizi yefuremu huru yakakura kana kuti ine zvikamu zvakawanda, zvichiita kuti mutengo wefuremu huru uwedzere uye kugadziriswa kwacho kwakaoma;

4) Nekuti mabheyaringi e cylindrical roller anonzwa kugadzikana kwemhete dzemukati nedzekunze, haana kugadzirwa zvakanaka kana kuungana zvakanaka.

Muchiitiko ichi, kucheneswa kwe radial kwemabheyaringi e spherical roller kuchaita kuti ma cylindrical rollers akuvadzwe;

5) Nekuda kwehukuru hudiki hwemubato nebearing, kuomarara kwese kwehurongwa hwekupinza shaft kwakaderera, uye mutoro une simba guru pamubato.

 

Mabheyaringi eroller ane mitsara miviri yakatetepa + mabheyaringi eroller ane cylindrical

Zvakanakira zvikuru zvechimiro ichi chebheyaringi ndeizvi:

1) Hapana nzvimbo ye axial clearance, uye nzvimbo ye axial positioning iri nani;

2) Kugona kwekutakura zvinhu kunogona kuwedzerwa nekuwedzera daro riri pakati pemabheyaringi, uye huwandu hunoshanda hwemabheyaringi hwakakura;

3) Dhayamita yemubato nebheyaringi idiki, uye mutengo wakaderera;

4) Nekuda kwekubviswa kwenzvimbo ye axial clearance, kuomarara kwese kwe shaft system kwakakwira, uye mutoro unoshanduka hauna simba pairi.
