Ipai huchokwadi hwemabhengi chaiwo mushure mekuiswa
1. Nzira yekuvandudza kwakarurama
Mushure mokunge kubereka kwaiswa mujini huru, kana radial runout yegomba guru yakayerwa, inogona kuwanikwa kuti kuyerwa kwehuwandu hwekuchinja kwega kwega kune imwe shanduko;kana kuyerwa kunoramba kuchiitwa, zvinogona kuwanikwa kuti mushure meimwe nhamba yekuchinja, shanduko iyi inenge ichidzokorora.Kuonekwa.Indekisi yekuyera dhigirii yeshanduko iyi ndeye cyclic kutenderera kwechokwadi.Huwandu hwemabhindauko anodiwa kuti shanduko iratidzike dzinenge dzadzokororwa inomiririra "quasi-nguva" yekutenderera chaiko.Hukuru hweshanduko muquasi-period yakakura, inova iyo yakashata cyclic kutenderera kurongeka..Kana preload yakakodzera ikaiswa kune main shaft, kumhanya kunowedzerwa zvishoma nezvishoma kusvika pedyo nekumhanya kwekushanda, kuitira kuti iite "run-in" mhedzisiro yekutakura, iyo inogona kuvandudza cyclic kutenderera kweiyo shaft huru.
2. Nzira yekuvandudza kubereka kurongeka
Muyedzo wefekitari-unogadzira zviridzwa zvemhando yepamusoro, shaft huru inoshandisa 6202/P2 mhando mabearings uye iko kurongeka kwayo kuchiri kusakwanisa kuzadzisa zvinodiwa, wobva wakora jenari uye wogadzira nzira yekumhanya pairi kutsiva mhete yemukati, uye kuyera glutinous density yesimbi. bhora, zvichienderana nehukuru Boka rimwe nerimwe remabhora matatu esimbi rinoparadzaniswa nepakati peinoda kusvika 120 °.Nekuda kwekuderedzwa kwenzvimbo inorema machining uye inorema inofananidzwa pamusoro, kusimba kweiyo shaft-bearing system inovandudzwa, uye makuru matatu mabhora uye madiki matatu mabhora ndeayo. iyo shaft, nokudaro kusangana nekururama zvinodiwa zvechiridzwa.
3. Comprehensive verification nzira yekuisa kururama
Mushure meiyo angular yekubata bhora bhora yakaiswa muspindle, iyo yekumisikidza kunyatsoita cheki kutevedzana kunotevera (kutora yakajairika lathe ine shaft dhayamita ye60-100mm semuenzaniso):
(1) Edza saizi yeshaft uye gomba rechigaro chekutakura kuti uone kuenderana kweiyo fani.Zvinodiwa zvekufananidza ndezvizvi zvinotevera: mhete yemukati uye shaft zvinotora kupindirana, uye huwandu hwekukanganisa i0~+4μm (0 yemutoro wakareruka uye nehupamhi hwepamusoro); Mhete yekunze negomba rechigaro chinotakura zvinotora kuenderana, uye iyo yemvumo yemvumo ndeye 0 ~ + 6μm (asi kana iyo yemahara yekupedzisira inotakura inoshandisa angular yekubata bhora, iyo clearance inogona zvakare kuwedzerwa);kukanganisa kwekutenderera kwepamusoro pakati pegomba negomba rechigaro pasi pe2μm, kutakura Kufananidzwa kwekuguma kwechiso che spacer chinoshandiswa chiri pasi pe 2μm, kubuda kwemukati wemukati wechipfuva chepfudzi kunotarisana nechekunze kwekupedzisira kwekunze kuri pasi pe2μm. ;kubuda kwegomba rechigaro chekutakura pfudzi kune axis iri pasi pe4μm;kubuda kwemukati mekupedzisira kwechifukidziro chekumberi kwakatarisana neaxis kuri pazasi 4μm.
(2) Pakugadzika kwebhengi remberi kumucheto wakagadziriswa pashaft, nyatsochenesa fani nekuchenesa parafini.Pakuzora mafuta, tanga wabaya organic solvent ine 3% kusvika 5% girizi mubereko yekudzikisa uye kuchenesa, wobva washandisa Iyo pfuti yemafuta inozadza imwe huwandu hwegirisi mubereko (inoverengera 10% kusvika 15% yekutakura. vhoriyamu yenzvimbo);kupisa kutakura kukwidza kutonhora kusvika ku20 kusvika ku30 ° C, uye kuisa kutakura mumucheto we shaft ne hydraulic press;dzvanya iyo adapta sleeve pane shaft Uye dzvanya iyo yekupedzisira kumeso kwebearing nekumanikidza kwakakodzera kuti iite axially positioned;monera bhanhire remuyero wechirimo pachindori chekunze chekutakura, uye shandisa nzira yekuyera torque yekutanga kuti uone kana iyo yakatarwa preload ine shanduko huru (kunyangwe kana kubereka kwacho kwakarurama)., asi iyo preload inogona zvakare kuchinja nekuda kwe deformation yefit kana cage).
(3) Isa mubatanidzwa webearing-shaft mugomba rechigaro, pisa gomba rechigaro kuti ukwidze tembiricha ne20-30°C, uye shandisa zvinoramba zvichimanikidza kupfava kuisa mubatanidzwa webearing-shaft mugomba rechigaro;gadzirisa chivharo chepamberi kuti chifukidziro chepamberi chisimbise Iyo yakasimba chiyero ndeye 0.02 ~ 0.05μm, zvichibva kune yekunze kwekupedzisira chiso chechigaro chekutakura, musoro wechiratidzo chedhiya unopesana nepamusoro pejenari, uye shaft inotenderedzwa kuenda. kuyera runout, uye kukanganisa kunodiwa kuve pasi pe10μm;iyo dial indicator yakaiswa pane shaft., musoro wegeji unopesana nechemukati megomba rechigaro chemashure, uye shaft inotenderedzwa kuyera coaxiality yepamberi uye kumashure kwezvigaro zvechigaro chekutakura.
