Ko bearing technology iri kuchinja sei?

Mumakumi mashoma emakore apfuura, dhizaini yemabhengi yafambira mberi zvakanyanya kuunza kushandiswa kwezvinhu zvitsva, tekinoroji yemhando yepamusoro uye kuongororwa kwekombuta..

Bearings anoshandiswa mune angangoita ese marudzi emuchina unotenderera. Kubva pakudzivirira uye midziyo yemuchadenga kusvika kumitsara yekugadzira chikafu nechinwiwa, kudiwa kwezvikamu izvi kuri kuwedzera. Nehurombo, mainjiniya ekugadzira ari kuwedzera kuda zvidiki, zvakareruka uye zvakasimba mhinduro kugutsa kunyangwe yakanyanya kuyedzwa yemamiriro ekunze.

 

Materials science

Kuderedza kupokana inzvimbo yakakosha yekutsvagisa kune vanogadzira. Zvinhu zvakawanda zvinokanganisa kupokana senge dimensional kushivirira, kupera kwepamusoro, tembiricha, basa rekuita uye kumhanya. Kufambira mberi kukuru kwakaitwa mukutakura simbi mumakore apfuura. Masimbi emazuva ano, akanyanya kucheneswa ane zvidimbu zvidiki uye zvidiki zvisiri zvesimbi, zvinopa mabhora ebhora kusamira zvakanyanya kubata kuneta.

 

Nzira dzemazuva ano dzekugadzira simbi uye de-gassing dzinobudisa simbi ine mazinga akaderera eokisidhi, sulphides uye mamwe magasi akanyungudutswa apo maitiro ekuomesa ari nani anobudisa simbi yakaoma uye yakawanda isingapfekeki. Kufambira mberi mumakina ekugadzira kunogonesa vagadziri vemabheji chaiwo kuti vachengetedze kushivirira padyo muzvikamu zvinotakura uye kugadzira nzvimbo dzakanyanya kukwenenzverwa, izvo zvinoderedza kupokana nekuvandudza mararamiro ehupenyu.

 

Nyowani 400-giredhi simbi isina tsvina (X65Cr13) yakagadziridzwa kuti ivandudze kubereka ruzha mazinga pamwe neakakwira nitrogen masimbi ekudzivirira kukuru kwekuora. Kune nharaunda dzinoparadza zvakanyanya kana tembiricha yakanyanyisa, vatengi vanogona ikozvino kusarudza kubva pakati pe316-giredhi Stainless simbi mabearings, yakazara ceramic bearing kana epurasitiki mabearings akagadzirwa kubva acetal resin, PEEK, PVDF kana PTFE. Sezvo 3D kudhinda kunowedzera kushandiswa zvakanyanya, uye nekudaro zvakanyanya kudhura, tinoona kuwedzera mikana yekugadzirwa kweasina-standard maretainer ekuchengetedza muhuwandu hudiki, chimwe chinhu chinozobatsira kune yakaderera vhoriyamu zvinodiwa zvehunyanzvi mabheji.

 

Lubrication

 

Kuzora kungave kwaita kuti vanhu vakawanda vatariswe. Iine 13% yekutadza kubereka kunokonzerwa nemafuta ekuzora, kutakura lubrication inzvimbo inokurumidza kubuda yekutsvagisa, inotsigirwa nevadzidzi neindasitiri zvakafanana. Ikozvino kune mamwe akawanda emafuta ekuzora ane hunyanzvi nekuda kwehuwandu hwezvikonzero: huwandu hwakakura hwemhando yepamusoro yemafuta ekugadzira, sarudzo huru yemakobvu anoshandiswa mukugadzira girisi uye yakakura siyana yekuwedzera mafuta ekuzopa, semuenzaniso, kugona kwepamusoro. kana kukura kwekusagadzikana. Vatengi vanogona kutsanangura magirosi akacheneswa zvakanyanya-akaderera ruzha, magirosi anomhanya-mhanya, mafuta ekuzora kupisa kwakanyanya, mafuta asingapindi mvura uye anodzivirira kemikari, mafuta ekuzora akakwira-vacuum uye mafuta ekuzora.

 

Kuongorora kwekombiyuta

 

Imwe nharaunda iyo indasitiri yekutakura yakaita nhanho huru ndeyekushandisa kubereka simulation software. Ikozvino, kubereka mashandiro, hupenyu uye kuvimbika kunogona kuwedzerwa kupfuura izvo zvakawanikwa makore gumi apfuura pasina kutora marabhoritari inodhura-inopedza nguva kana bvunzo dzemumunda. Yepamberi, yakabatanidzwa ongororo yekutenderedza element mabearings inogona kupa isingaenzaniswi nzwisiso mukubereka mashandiro, inogonesa kwakaringana kubereka kusarudzwa uye kudzivirira kutadza kubereka nguva isati yakwana.

 

Nzira dzehupenyu dzekuneta dzinogona kubvumira kufanotaura kwakaringana kwechinhu uye kushushikana kwemujaho, kubata mbabvu, kushushikana kwemupendero, uye kubata truncation. Ivo zvakare vanobvumidza yakazara sisitimu kutsauka, kuongororwa kwemutoro uye kutakura misalignment kuongororwa. Izvi zvinopa mainjiniya ruzivo rwekugadzirisa dhizaini yekubereka kuti igadzirise zvirinani kushushikana kunobva kune chaiyo application.

 

Imwe mukana wakajeka ndeyekuti simulation software inogona kuderedza huwandu hwenguva uye zviwanikwa zvakashandiswa pachikamu chekuyedza. Izvi hazvingo mhanyisa maitiro ekusimudzira asiwo zvinoderedza mari mukuita.

 

Zviripachena kuti zvinhu zvitsva zvinogadzirwa nesainzi pamwe chete nematurusi epamusoro ekufananidza zvinopa mainjiniya njere inodiwa kugadzira nekusarudza mabearings ekuita kwakanyanya uye kusimba, sechikamu cheyose system modhi. Kuenderera mberi nekutsvagisa nekusimudzira muminda iyi kuchave kwakakosha mukuona kuti mabhengi anoramba achisundidzira miganhu mumakore anotevera.
