Ball screw, chiri chechimwe chezvikamu zvemakina ekushandisa mabearings, chinhu chakanakira muchina chinotakura chigadzirwa chinogona kushandura kutenderera kufamba kuita.linear kufamba.Ball screw ine screw, nut, reversing device nebhora, uye ine hunhu hwepamusoro nemazvo, reversibility uye hunyanzvi hwepamusoro panguva imwe chete.
Pane nzira nhatu huru dzekuisa bhora sikuruu, dzinoti, imwe mugumo wakagadziriswa, imwe magumo emahara yekuisa nzira;imwe mugumo wakagadziriswa, imwe mugumo inotsigira yekuisa nzira;zvose zvinoguma zvakagadziriswa nzira yekuisa.
1,Imwe mugumo wakagadziriswa, imwe mugumo wakasununguka nzira
Imwe magumo yakagadziriswa, imwe yekupedzisira yemahara yekuisa nzira: yakagadziriswa magumo eiyokuberekainogona panguva imwe chete kumira axial simba uye radial simba, nepo bhora iyi nzira yekutsigira inonyanya kukodzera kune diki sitiroko pfupi screw bearings kana yakavharirwa zvizere muchina maturusi, nekuti kana uchishandisa ichi chimiro chemichina yekumisikidza nzira, kurongeka kwayo ndiko kusavimbika, kunyanya kureba. -dhiyamita reshiyo yehukuru screw bearings (bhora screw iri kutetepa), deformation yayo yekupisa iri pachena.Iyo Zvisinei, kune 1.5m kureba sikuruu, kusiyanisa kwe 0.05 ~ 0.1mm pasi pemamiriro akasiyana ekutonhora nekupisa kwakajairika.Zvakadaro, nekuda kwechimiro chayo chakareruka uye nyore kugadzika uye kutumwa, akawanda epamusoro-chaiyo maturusi emuchina achiri kushandisa chimiro ichi.Zvisinei, pane imwe pfungwa inoda kutariswa kwakakosha ndeyekuti kushandiswa kwechimiro ichi kunofanira kuwedzerwa kune grating, uchishandisa mhete yakavharwa zvakakwana kune mhinduro, kuitira kuti ugone kunyatsoita screw performance.
2, imwe mugumo wakagadziriswa, imwe magumo ekutsigira maitiro
Imwe mugumo yakagadziriswa uye imwe mugumo inotsigirwa: kubereka pamagumo akagadziriswa anogonawo kumira zvose axial uye radial masimba, nepo kuguma kwekutsigira kunongomira simba remagetsi uye kunogona kuita zvishoma zvishoma zveaxial float, pamwe nekuderedza kana kudzivisa. kukotama kwesiruu nekuda kwehuremu hwayo.Uye zvakare, iyo yekupisa deformation yebhora screw rutsigiro inotakura screw yakasununguka kurebesa yakananga kune imwe mugumo.Nokudaro, iyi ndiyo inonyanya kushandiswa maitiro.Semuenzaniso, madiki uye epakati-saizi CNC lathes, vertical machining nzvimbo, nezvimwewo vari kushandisa chimiro ichi.
3,Yakagadziriswa kumativi ose maviri
Mamiriro ese ari maviri e screw akagadziriswa: Nenzira iyi, kutakura kumagumo akamisikidzwa kunogona kutakura axial simba panguva imwe chete, uye iyo yakakodzera preload inogona kuiswa kune screw kuti ivandudze tsigiro kuoma kwe screw, uye thermal. deformation ye screw inogona zvakare kubhadharwa zvishoma.Naizvozvo, maturusi emuchina mahombe, maturusi emuchina anorema uye akanyanya-chaiyo anofinha uye muchina wekugaya ndiwo anonyanya kushandiswa muchimiro ichi.Zvechokwadi, pane zvikanganiso, ndiko kuti, kushandiswa kwechimiro ichi kuchaita kuti kugadziriswa kushande zvakanyanya;uyezve, kana kuiswa uye kugadziriswa kwemagumo maviri ekutanga kwekutanga kwakakura zvakanyanya, zvinotungamirira kukurohwa kwekupedzisira kwe screw pane dhizaini yekugadzira, pitch ichavawo yakakura kudarika dhizaini yekugadzira;uye kana migumo miviri ye nut preload isina kukwana, inotungamira kune yakapesana mhedzisiro, izvo zvinokonzeresa kuzunguzika kwemuchina, zvichikonzera kuderedzwa kwechokwadi.Nokudaro, kana chimiro chacho chakagadziriswa kumativi ose maviri, ipapo disassembly inofanira kugadziriswa zvakanyatsoenderana nemirairo, kana nerubatsiro rwechiridzwa (dual frequency laser interferometer) kugadzirisa, kuitira kuti usakonzera kurasikirwa kusingakoshi.
