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;apo kuyerwa kunoitwa nguva dzose, zvinogona kuwanikwa kuti mushure meimwe nhamba yekuchinja, shanduko ichave inenge yakadzokororwa Kuonekwa.Indekisi yekuyera dhigirii yeshanduko iyi ndeye cyclic kutenderera kwechokwadi.Huwandu hwemabhindauko anodiwa pakudzokorora kudzokorora kweshanduko inomiririra "quasi-nguva" yeiyo cyclic kutenderera kwechokwadi.Ukuru hwekuchinja kweiyo quasi-nguva yakakura, kureva kuti, cyclic kutenderera kurongeka kwakashata..
Kana preload yakafanira ikaiswa kune main shaft, kumhanya kunowedzerwa zvishoma nezvishoma kusvika pedyo nekumhanya kwekushanda kuita "run-in" mhedzisiro yekubereka, iyo inogona kuvandudza cyclic kutenderera kweiyo shaft huru.
2. Nzira yekuvandudza kubereka kurongeka
Muyedzo wefekitori wakagadzira chiridzwa chaicho.Iyo huru shaft yakashandisa 6202/P2 mabheya, asi iko kurongeka kwayo kuchiri kusakwanisa kuita zvinodiwa.Gare gare, jenari yakakora uye mugwagwa wakagadzirwa pairi kutsiva mhete yemukati.Boka rimwe nerimwe remabhora matatu rinopatsanurwa nepakati peinoda kusvika 120 °.Nekuda kwekuderedzwa kwenzvimbo inorema yekugadzira uye inorema inofananidzira nzvimbo, inovandudzawo kuomarara kweiyo shaft-bearing system, nepo hombe nhatu tsanga uye diki nhatu Iyo inenge yakaenzana kugoverwa kwemabhora esimbi inovandudza kutenderera kweshaft. , nokudaro kusangana nekururama zvinodiwa zvechiridzwa.
3. Comprehensive verification nzira yekuisa kururama
Mushure mekuisa iyo angular yekubata bhora inotakura mukati mehombe shaft, iyo yekumisikidza kunyatsoita nhevedzano inoteedzana seinotevera (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 kupindira kunokodzera i 0~+4μm (0 pakuremerwa kwakareruka uye nehupamhi hwepamusoro); Mhete yekunze negomba remba zvinotora inokwana, uye iyo clearance ndeye 0 ~ + 6μm (asi iyo clearance inogona kuwedzerwa kana kutakura pakupera kwemahara kunoshandisa angular yekubata bhora kutakura);kukanganisa kwekutenderera kwe shaft uye nzvimbo yegomba reimba iri pasi pe 2μm, uye kutakura Kufananidzwa kwekupedzisira kwechiso che spacer yakashandiswa iri pasi pe 2 μm, kubuda kwemukati wemukati wepfudzi pfudzi kusvika kumucheto wekunze kwekunze ndiko. isingasviki 2 μm;kubuda kwepfudzi yegomba reimba inotakura kune axis iri pasi pe4 μm;kubuda kwemukati mekupedzisira kwechivharo chikuru chemberi kune axis iri pasi pe 4 μm.
(2) Kuiswa kwemberi kumberi kweiyo yakagadziriswa yekupedzisira pane shaft
Gadzirisa faniro neparafini yakachena yekuchenesa.Pakuzora mafuta, tanga wabaya organic solvent ine 3% kusvika 5% girizi mubereko yekubvisa nekuchenesa, wobva washandisa pfuti yegirizi kuzadza imwe huwandu hwegirisi mubereko (inoverengera 10% kusvika 15% yemafuta. kutakura nzvimbo volume);kupisa kutakura kusimudza kutonhora ne 20 kusvika ku 30 ° C, uye kuisa kutakura mumucheto we shaft ne hydraulic press;dzvanya iyo adapta sleeve pane shaft uye dzvanya uchipokana neinotakura magumo kumeso nekumanikidza kwakakodzera kuti iite axially Positioning;mhepo bhandi rechitubu chikero pane yekunze mhete yekutakura, uye shandisa nzira yekuyera torque yekutanga kuona kana iyo yakatarwa preload ine shanduko huru (kunyangwe kana kutakura kwacho kwakaringana, asi nekuda kwekushanduka kweiyo fit. kana keji, preload ichachinjawo.
(3) Isa gungano rekubereka-shaft mugomba rechigaro
Pisa gomba rechigaro kuti uwedzere kutonhora ne 20-30 ° C, uye isa gungano rekubereka-shaft mugomba rechigaro nekuenderera uye kunyorova kudzvinyirira;gadzirisa chivharo chepamberi kuitira kuti chiyero chekuisa chevhavha yepamberi ive 0.02-0.05 μm, uchitora nzvimbo yekunze yechigaro chekutakura seBenchmark, isa musoro weiyo dial gauge pakatarisana nejenari, tenderedza shaft kuyera. kupera kwayo, uye kukanganisa kunodiwa kuve pasi pe10 μm;isa iyo dial gauge pane shaft, ita kuti musoro weiyo dial ubate mukati megomba rechigaro chemashure, uye tenderera shaft Kuyera coaxiality yepamberi uye kumashure makomba edzimba dzechigaro chekutakura.
(4) Sarudzo isa mhedziso yemahara panzvimbo inogona kumisa kutsauka, woiisa kuseri kwerutsigiro chinzvimbo cheiyo imba inotakura kuti ibvise kutenderera kwekutenderera uye coaxiality kutsauka zvakanyanya sezvinobvira.
Kuiswa kwekaviri-mutsara mapfupi cylindrical roller mabearings ane tapered bore Pakuisa NN3000K yakatevedzana kaviri-mutsara mapfupi cylindrical roller mabearings ane tapered bore, kutarisisa kunofanirwa kubhadharwa kune kuenderana kwakaringana kwemukati dhayamita yekutakura uye taper ye shaft, uye iyo nzira yekupenda inogona kushandiswa munyaya yehuwandu hudiki hwekugadzira.Bata calibration, asi kana batch yekugadzira yakakura, zviri nani kushandisa chaiyo taper geji yekuenzanisa.
Paunenge uchiisa bheya pane tapered shaft, mhete yemukati inofanira kugadziridzwa kune imwe nzvimbo yakakodzera mugwara reaxial kuitira kuti radial clearance iri pedyo ne zero.
