Kukutora kuti uzive kukosha

Sechinhu chakakosha uye chakakosha muzvigadzirwa zvemakanika, mabheyaringi anoita basa rakakosha mukutsigira shafts dzinotenderera. Zvichienderana nehunyanzvi hwakasiyana hwekukweshana mubheyaringi, iyokuberekaYakakamurwa kuita rolling friction bearing (inonzi rolling bearing) uye sliding friction bearing (inonzi sliding bearing). Mhando mbiri dzemabheya dzine hunhu hwadzo muchimiro, uye imwe neimwe ine zvayakanakira nezvayakaipira mukushanda kwayo.

Kuenzanisa kwekutenderera uyemabheyaringi asina chinhu

1. Kuenzanisa kwechimiro uye maitiro ekufamba

Musiyano uri pachena pakati pemabheyaringi anotenderera nemabheyaringi asina kutenderera ndewekuvapo kana kusavapo kwezvinhu zvinotenderera.

Mabheyaringi anotenderera ane zvinhu zvinotenderera (mabhora, marori anotenderera, marori ane tapered, marori ane needle) anovimba nekutenderera kwawo kuti atsigire shaft inotenderera, saka chikamu chekubatana chinova poindi, uye zvinhu zvinotenderera zvakawanda, nzvimbo dzekubatana dzinowanda.

Mabheyaringi asina zvinhu zvinotenderera uye anovimba nenzvimbo dzakatsetseka kuti dzitsigire mubato unotenderera, saka chikamu chekubata chinhu chakafanana nepamusoro.

Musiyano uripo muchimiro chezviviri izvi unoratidza kuti movement mode ye rolling bearing iri kutenderera, uye movement mode ye sliding bearing iri kutenderera, saka mamiriro ekukweshana akasiyana zvachose.

 

2. Kuenzanisa kwesimba rekutakura

Kazhinji, nekuda kwenzvimbo yakakura yekutakura bearing inotsvedza, kugona kwayo kubearing kwakawanda kupfuura kwebearing inotenderera, uye kugona kwebearing inotenderera kutakura mutoro weimpact hakuna kukwira, asi bearing yakanyoroveswa nemvura yakakwana inogona kutakura mutoro mukuru weimpact nekuda kwebasa re cushioning uye vibration absorption nekuda kwemafuta anozora. Kana kumhanya kwekutenderera kwakakwira, simba re centrifugal rezvinhu zvinotenderera mubearing inotenderera rinowedzera, uye kugona kwayo kubearing kunodzikira (ruzha runowanzoitika nekumhanya kwakanyanya). Kana iri dynamic plain bearing, kugona kwayo kubearing kunowedzera nekumhanya kwakakwira.

3. Kuenzanisa kwe friction coefficient uye kutanga friction resistance

Mumamiriro ekushanda akajairika, chiyero chekukweshana kwemabearings anotenderera chakaderera pane cheplain bearings, uye kukosha kwacho kwakasimba. Kunyoroveswa kwemabearings anotsvedza kunokanganiswa nyore nyore nezvinhu zvekunze zvakaita sekumhanya nekudedera, uye chiyero chekukweshana chinosiyana zvakanyanya.

Pakutanga, kupokana kwakakura kupfuura kwebheyaringi rinotenderera nekuti beyaringi rinotsvedza harisati ragadzira firimu remafuta rakagadzikana, asi kupokana kwekutanga kwekusvetana uye coefficient yekushanda kwebeyaringi rinotsvedza rehydrostatic idiki kwazvo.

 

4. Kuenzanisa kumhanya kwekushanda kunoshanda

Nekuda kwekuganhurirwa kwesimba re centrifugal rechinhu chinotenderera uye kukwira kwekupisa kwebearing, kumhanya kwebearing rinotenderera hakufanirwe kuve kwakanyanya, uye kazhinji kwakakodzera mamiriro ekushanda ari pakati nepakati uye pasi. Mabearing asina kukwana emvura ane mafuta nekuda kwekupisa uye kupera kwebearing, kumhanya kwekushanda hakufanirwe kunge kwakanyanya. Kushanda nekukurumidza kwemabearing ane mafuta akazara nemvura kwakanaka kwazvo, kunyanya kana mabearing e hydrostatic plain akanyoroveswa nemhepo, uye kumhanya kwawo kwekutenderera kunogona kusvika 100,000 r/min.

 

5. Kuenzanisa kurasikirwa kwesimba

Nekuda kwekusakwana kwemabearings ekutenderera, kurasikirwa kwesimba ravo kazhinji hakusi kukuru, izvo zviri pasi pemabearings asina kukwana emvura, asi zvichawedzera zvakanyanya kana zvaiswa mafuta uye zvaiswa zvakanaka. Kurasikirwa kwesimba rekusangana kwemabearings akanyoroveswa nemvura kwakaderera, asi kumabearings emvura, kurasikirwa kwesimba rose kunogona kunge kwakakwira kupfuura kwemabearings emvura nekuda kwekurasikirwa kwesimba repombi yemafuta.

 

6. Kuenzanisa hupenyu hwebasa

Nekuda kwesimba rekuisa zvinhu pasi uye kuneta, mabheyaringi anotenderera anowanzo gadzirwa kwemakore mashanu kusvika gumi, kana kutsiviwa panguva yekugadzirisa. Mapedhi emabheyaringi asina kukwana anonyoroveswa nemvura anosakara zvakanyanya uye anoda kutsiviwa nguva nenguva. Hupenyu hwemabheyaringi anonyoroveswa nemvura hunogara husina muganho, asi mukuita, kuneta kwechinhu chinonyoroveswa kunogona kuitika nekuda kwekumanikidzwa, kunyanya kumabheyaringi akajeka.

 

7. Kuenzanisa kururama kwekutenderera

Mabheya anotenderera anowanzo kuve nekutenderera kwakanyanya nekuda kwenzvimbo diki ye radial. Beya risina kukwana rakanyoroveswa nemvura riri mumamiriro ekunyoroveswa kwemuganhu kana kunyoroveswa kwakasanganiswa, uye mashandiro acho haana kugadzikana, uye kupera kwakanyanya, uye kurongeka kwakaderera. Nekuda kwekuvapo kwefirimu remafuta, mabheya anonyoroveswa nemvura anonyatsotora vibration nekunyatsojeka. Mabheya e hydrostatic plain ane kutenderera kwakanyanya.

 

8. Kuenzanisa zvimwe zvinhu

Mabheya anotenderera anoshandisa mafuta, mafuta kana mafuta akasimba, huwandu hwacho hudiki kwazvo, huwandu hwacho hwakawanda nekumhanya kwakanyanya, kuchena kwemafuta kunodiwa kuti kuve kwakakwirira, saka kunofanirwa kuvharwa, asi beya iri nyore kutsiva, uye kazhinji haidi kugadzirisa journal. Kune mabheya asina kuzara, kuwedzera kumabheya asina kukwana emafuta, mafuta acho anowanzova emvura kana gasi, huwandu hwacho hwakawanda kwazvo, zvinodiwa zvekuchena kwemafuta zvakanyanyawo, mabheya anogadziriswa anofanira kutsiviwa nguva nenguva, uye dzimwe nguva journal inogadziriswa.

 

Kusarudzwa kwemabheyaringi anotenderera uyemabheyaringi asina chinhu

Nekuda kwemamiriro ekushanda akaomarara uye akasiyana-siyana, hapana mwero wakabatana wekusarudza ma rolling bearings nema sliding bearings. Nekuda kwe friction coefficient diki, starting resistance diki, sensitivity, high efficiency, uye standardization, rolling bearings dzine kuchinjana kwakanaka uye kushanduka-shanduka, uye zviri nyore kushandisa, kuisa mafuta uye kuchengetedza, uye dzinowanzo kupihwa pekutanga mukusarudza, saka dzinoshandiswa zvakanyanya mumichina yakajairika. Plain bearings dzine zvakanakira zvakasiyana pachadzo, uye dzinowanzo shandiswa mune dzimwe nguva apo rolling bearings dzisingagoneki, dzisingakodzeri kana dzisina zvakanakira mukushandisa rolling bearings.
