Nzira yekuyera sei kubereka axial clearance
Pakusarudza kutakura clearance, zvinotevera zvinofanirwa kutariswa:
1. Mamiriro ekushanda ekutakura, zvakadai semutoro, tembiricha, kukurumidza, nezvimwewo;
2. Zvinodiwa zvekutakura kuita (kutenderera kwechokwadi, friction torque, vibration, ruzha);
3. Apo kutakura uye shaft uye gomba reimba iri mukupindirana, kusununguka kwekutakura kunoderedzwa;
4. Kana kubereka kuri kushanda, kusiyana kwekushisa pakati pezvindori zvemukati nekunze kunoderedza kusununguka kwekutakura;
5. Yakaderedzwa kana kuwedzera kutakura mvumo nekuda kwekuwedzera kwakasiyana-siyana coefficients ye shaft uye zvinhu zveimba.
Maererano neruzivo, iyo yakanyatsokodzera kushanda clearance yebhora mabearings iri pedyo ne zero;roller bearings inofanira kuchengetedza zvishoma zvekushanda clearance.Muzvikamu zvinoda kusimba kwerutsigiro, FAG mabheji anobvumira imwe huwandu hwe preload.Inonyanya kutaurwa pano kuti iyo inonzi clearance yekushanda inoreva kubviswa kwekutakura pasi pemamiriro chaiwo ekushanda.Kune zvakare mhando yemvumo inonzi yepakutanga clearance, iyo inoreva kubvumidzwa kusati kwaiswa.Iyo yepakutanga clearance yakakura pane yakaiswa clearance.Sarudzo yedu yemvumo inonyanya kusarudza yakakodzera yekushanda clearance.
Hukoshi hwemvumo hwakatarwa muchiyero chenyika zvakakamurwa kuita mapoka matatu: boka rekutanga (boka 0), boka rekubatsira rine diki clearance (boka 1, 2) uye boka rekubatsira rine yakakura clearance (boka 3, 4, 5).Pakusarudza, pasi pemamiriro ekushanda akajairika, boka rekutanga rinofanira kusarudzwa, kuitira kuti kutakura kunogona kuwana mvumo yekushanda yakakodzera.Kana boka rekutanga risingakwanisi kuzadzisa zvinodiwa zvekushandisa, mvumo yeboka rekubatsira inofanira kusarudzwa.Iyo yakakura clearance yekubatsira boka inokodzera kupindirana kwakakodzera pakati pekutakura uye shaft uye gomba remba.Kusiyana kwekushisa pakati pezvindori zvemukati nekunze zvekutakura zvakakura.Iyo yakadzika groove bhora inotakura inoda kutakura yakakura axial mutoro kana inoda kuvandudza yekuzvigadzirisa kuita.Deredza friction torque yeNSK bearings uye dzimwe nguva;iro diki rekubatsira boka rekubatsira rakakodzerwa nezviitiko zvinoda kutenderera kwepamusoro, kunyatso kudzora kusimuka kweaxial yegomba remba, uye kuderedza vibration uye ruzha.1 Kugadzirisa kubereka
Mushure mekuona mhando uye modhi yekutakura, zvinodikanwa kunyatso gadzira iyo yakasanganiswa chimiro cheiyo rolling bearing kuti ive nechokwadi chekushanda kwakajairwa kweTIMKEN inotakura.
Iyo yakasanganiswa chimiro dhizaini yekubereka inosanganisira:
1) Shafting tsigiro yekupedzisira chimiro;
2) Kubatana kwemabhengi uye zvikamu zvinoenderana;
3) Kuzora uye kuiswa chisimbiso kwemabhengi;
4) Kuvandudza kuoma kweiyo inotakura system
1. Yakagadziriswa kumativi ose maviri (imwe-nzira yakagadziriswa kumativi ose maviri) Kune mapfupi shafts (span L<400mm) pasi pekushisa kwemazuva ose ekushanda, fulcrum inowanzogadziriswa nenzira imwe chete kumativi ose maviri, uye imwe neimwe inotakura inotakura axial simba mune imwe. direction.Sezvinoratidzwa mumufananidzo, kuitira kuti ubvumire huwandu hushoma hwekuwedzera kwekupisa kwe shaft panguva yekushanda, kutakura kunofanira kuiswa neaxial clearance ye 0.25mm-0.4mm (kubvumirwa kuduku zvikuru, uye hazvidiwi dhirowa pamufananidzo wechimiro).
Zvimiro: Deredza bidirectional kufamba kweaxis.Inokodzera shafts ine shanduko shoma mukushanda tembiricha.Ongorora: Tichifunga nezvekureba kwekupisa, siya muripo wemuripo c pakati pechifukidziro chekutakura uye nechekunze kwekupedzisira kwechiso, c=0.2 ~ 0.3mm.2. Imwe mugumo inogadziriswa kumativi ose uye imwe mugumo ndeyekushambira.Kana iyo shaft yakareba kana kutonhora kwekushanda kwakakwirira, kuwedzera kwekushisa uye shrinkage ye shaft yakakura.
Mhedzisiro yakagadziriswa inoiswa pasi pe bidirectional axial simba neboka rimwe chete rinotakura kana kutakura, nepo kuguma kwekusununguka kunovimbisa kuti shaft inogona kushambira zvakasununguka kana ichiwedzera uye zvibvumirano.Kuti udzivise kusunungura, mhete yemukati yekutakura inoyerera inofanira kunge yakagadziriswa neaxially ne shaft (a circlip inowanzoshandiswa).Zvimiro: Imwe fulcrum inomiswa mumativi ese, uye imwe fulcrum inofamba axially.Iyo yakadzika groove bhora rinotakura rinoshandiswa seyakayangarara fulcrum, uye pane gaka pakati pemhete yekunze yebearing uye yekupedzisira chivharo.Cylindrical roller bearings inoshandiswa se fulcrum inoyangarara, uye mhete yekunze yekutakura inofanira kugadziriswa kumativi ose maviri.
Inoshanda: Yakareba axis ine hombe tembiricha shanduko.
