Sei michina mizhinji yekuchera ichisarudza mabheyaringi anotenderera pachinzvimbo chemabheyaringi anotsvedza?

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

Kuenzanisa kwemabheyaringi anotenderera uye asina chinhu

1. Kuenzanisa kwechimiro uye maitiro ekufamba

Musiyano uri pachena pakati pemabheyaringi anotenderera uyemabheyaringi asina chinhukuvapo 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 chinhuHadzina zvinhu zvinotenderera uye dzinovimba 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 uye mabheyaringi 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 pachadzo dzine zvakanakira zvakasiyana, izvo zvinowanzo shandiswa mune dzimwe nguva apo rolling bearings dzisingakwanise kushandiswa, dzisingakodzeri kana dzisina zvakanakira, senge zvinotevera:

 

1. Saizi yenzvimbo ye radial yakaganhurirwa, kana kuti kuiswa kwayo kunofanira kupatsanurwa

Nekuda kwemhete yemukati, mhete yekunze, chinhu chinotenderera uye keji iri muchimiro, saizi yeradial yebearing inotenderera yakakura, uye kushandiswa kwayo kwakaganhurirwa kusvika pamwero wakati. Mabheyaringi eroller needle anowanikwa kana saizi yeradial iri yakasimba, uye kana zvichidikanwa, mabheyaringi asina kujeka anodiwa. Kune zvikamu zvisingakodzeri kuva nemabheyaringi, kana zvisingakwanise kuiswa kubva kudivi re axial, kana uko zvikamu zvinofanirwa kupatsanurwa kuita zvikamu, mabheyaringi asina kujeka anoshandiswa.

 

2. Zviitiko zvakanyatsonaka

Kana bearing inoshandiswa iine zvinodiwa zvakanyatsonaka, bearing inotsvedza inowanzo sarudzwa, nekuti firimu remafuta ekuzora rebearing inotsvedza rinogona kuvharidzira kunyudzwa kwe vibration, uye kana kunyatsonaka kwacho kwakanyanya, bearing inotsvedza ye hydrostatic chete ndiyo inogona kusarudzwa. Kune michina yekukuya yakanyatsonaka uye yakanyatsonaka, zvishandiso zvakasiyana-siyana zvekugadzirisa, nezvimwewo, mabearing anotsvedza anoshandiswa zvakanyanya.

 

3. Zviitiko zvinorema

Mabheyaringi anotenderera, angave mabheyaringi ebhora kana mabheyaringi anotenderera, anowanzo pisa uye kuneta mumamiriro ezvinhu anorema. Nokudaro, kana mutoro wacho wakakura, mabheyaringi anotsvedza anonyanya kushandiswa, akadai semarolling mills, ma steam turbines, zvishandiso zveinjini yeaero uye michina yekuchera.

 

4. Dzimwe nguva

Semuenzaniso, kumhanya kwekushanda kwakanyanya, kuvhunduka nekudedera zvakakura zvikuru, uye kudiwa kwekushanda mumvura kana muchina unoparadza, nezvimwewo, mabheyaringi anotsvedza anogonawo kusarudzwa zvine musoro.

 

Kune mhando yemichina nemidziyo, kushandiswa kwema rolling bearings nema sliding bearings, imwe neimwe ine zvayakanakira nezvayakaipira, uye inofanira kusarudzwa zvine musoro pamwe chete neprojekti chaiyo. Kare, ma crushers makuru nepakati aiwanzoshandisa ma sliding bearings akaumbwa ne babbitt, nekuti aikwanisa kutsungirira mitoro mikuru, uye airamba kupera simba uye akagadzikana. Small jaw crusher inonyanya kushandiswa nema rolling bearings, ane simba rekutumira, anonyanya kugadzikana uye ari nyore kuchengetedza. Nekuvandudzwa kwehunyanzvi hwekugadzira ma rolling bearings, mazhinji ema large jaw breakers anoshandiswawo muma rolling bearings.
