Zvinonyanya kukosha kuenzanisa kutakura kwemukati dhayamita neshaft uye dhayamita yekunze neimba kana kutakura kuchiiswa. Kana iyo fit yanyanya kusununguka, iyo mating surface inoburitsa hama inotsvedza, inonzi creep. Kana nyoka ikangoitika, inopedza nzvimbo yekubatana, kukuvadza shaft kana imba, uye kupfeka hupfu hunopinda mukati mekutakura, zvichikonzera kupisa, kuzunguzika uye kukuvara. Kupindira kwakanyanya kuchaita kuti pave nediki dhayamita yekunze kwemhete yekunze kana yakakura yemukati dhayamita yemukati wemukati, izvo zvinoderedza kubvumidzwa kwemukati kwekutakura. Mukuwedzera, kurongeka kwejometri ye shaft uye shell processing kuchakanganisawo kurongeka kwepakutanga kwechindori chekutakura, nokudaro kuchikanganisa kushanda kwekubereka.

Semuenzaniso, kuiswa kwechikamu chepfudzi kana kururamisa kusina kunaka, zvindori zvemukati nekunze zvicharerekera. Mukuwedzera kune mutoro wekutakura, wakasanganiswa nemutoro wakaiswa pamagumo, hupenyu hwekuneta huchaderedzwa, uye zvakanyanya, huchava chikonzero chekukuvara kwekeji uye sintering. Mukuwedzera, iyo shell deformation nekuda kwemutoro wekunze haisi yakakura. Izvo zvinodikanwa kutsigira zvizere kuomarara kwekubereka. Iyo yakakwirira kuoma, zviri nani ruzha uye kugoverwa kwekutakura kwekutakura.
Mumamiriro ezvinhu akajairwa ekushandiswa, kutendeuka kumagumo machining kana kunyatsoita boring muchina kugadzirisa kunogona kuve. Nekudaro, kune zviitiko zvine hunyanzvi zvinodikanwa zvekutenderera runout uye ruzha uye mamiriro ekutakura akanyanya kuomarara, kugaya kwekupedzisira kuchashandiswa.

Iyo inodaidzwa kunzi clearance yemukati yebearing inoreva kuwanda kwekufamba kana mhete yemukati kana yekunze yebearing yakagadzikwa isati yaiswa pashaft kana bhokisi rekubereka, uyezve divi risina kumira rinofambiswa mu radial kana axial direction. . Zvinoenderana negwara rekufamba, rinogona kukamurwa kuita radial clearance uye axial clearance. Pakuyera kucheneswa kwemukati kwebearing, kuitira kuchengetedza kukosha kwakayerwa kugadzikana, muyedzo wekuyedza unowanzo kuisirwa mhete. Naizvozvo, kukosha kwekuyedzwa kwakakura pane iyo chaiyo clearance value, ndiko kuti, imwe yekuwedzera yakawanda yeelastic deformation inokonzerwa nekushandisa bvunzo mutoro. Iko kukosha chaiko kwekutakura kubvumidzwa kwemukati kunoratidzwa muTafura 4.5. Kuwedzera kwekuchenesa kunokonzerwa nepamusoro pe elastic deformation inogadziriswa. Iyo elastic deformation ye roller bearings haina basa. Tafura 4.5 kubvisa pesvedzero yeradial clearance bvunzo kururamisa mutoro (yakadzika groove bhora kutakura) mayuniti: um nominal kutakura modhi dhayamita d (mm) (N) clearance test kururamisa kururamisa kune C2 C3 C4 C510 zvakajairika (kusanganisira) 18 24.549 147 3 ~ 4 4 ~ 5 6 ~ 8 45 8 4 6 9 Kubvumbi 9 Kubvumbi 6 92.2 kusarudzwa kweiyo bearing clearance inotakura kubvumidzwa, nekuda kwekuenderana uye kusiyana kwetembiricha pane zvikonzero zvemukati nekunze, kazhinji idiki pane yekutanga clearance. Iyo yekushandisa clearance yakabatana zvakanyanya nehupenyu hwekubereka, kukwira kwekushisa, vibration uye ruzha, saka inofanirwa kuiswa kune yakanyanya kunaka mamiriro.
Tichingotaura, kana kutakura kuri kushanda, paine zvishoma zvisina kunaka kumhanya kubvumidzwa, hupenyu hwekubereka hwakanyanya. Asi zvakanyanya kuoma kuchengetedza iyi yakakwana clearance. Nekushanduka kwemamiriro ebasa, kubviswa kwakashata kwekutakura kuchawedzera zvakafanana, izvo zvinotungamirira kuderera kukuru kwekubereka hupenyu kana chizvarwa chekupisa. Naizvozvo, kubvisirwa kwekutanga kwebearing kazhinji kunoiswa kuve kwakakura zvishoma pane zero. FIG. 2 kusiyanisa kwekubereka radial clearance 2.3 Kusarudzwa kwemaitiro eKutakura clearance Zvinofungidzirwa, kutakura hupenyu hunokwidziridzwa kana paine kushoma kushoma kwekushanda clearance pasi pemamiriro ekushanda akachengeteka. Asi mukuita, zvakanyanya kuoma kuchengetedza iyi optimum mamiriro. Kana mamwe mamiriro ebasa achinja, iyo yakaipa clearance inowedzera, zvichikonzera kudzikira kwakanyanya mukubereka hupenyu kana kupisa. Nokudaro, apo kubvumirwa kwekutanga kunowanzosarudzwa, kushandiswa kwekushanda kunodiwa kuti kuve kwakakura zvishoma kudarika zero.
Kune mabhengi pasi pemamiriro ezvinhu akajairika, kurongeka kwemitoro yakafanana ichagamuchirwa. Kana iyo yekumhanyisa uye tembiricha zvakajairika, iyo inoenderana yakajairika clearance inofanirwa kusarudzwa kuti iwane yakakodzera yekushanda clearance. Tafura 6 yakajairwa kubvumidzwa semuenzaniso uchishandisa mamiriro anoshanda chiitiko chemvumo pasi pemutoro unorema, kutakura mutoro, kukanganiswa nehuwandu hukuru hwechitima ekisero C3 inozunguza screen C3 neC4 haikwanise kubhadhara inotungamira, mukati nekunze kwedenderedzwa reC4 tirakita tora static ne. njanji yemotokari inodhonza mota, inoderedza kana C4 inotakura yemukati mhete yekupisa pepa muchina, dryer C3 uye C4 mill roller kun C3 kuderedza kutenderera kutenderera uye ruzha rwe micro-motor C2 clearance kugadziridzwa uye kudzora kuzunguzika kweshaft NTN spindle (kaviri mutsara cylindrical roller. kubereka) C9NA, C0NA.
