Kukwana kwebheyaringi uye clearance

Zvakakosha kuenzanisa dhayamita yemukati mebearing neshaft uye dhayamita yekunze nehousing kana bearing yaiswa. Kana fit yacho yakasununguka zvakanyanya, nzvimbo yekusangana ichaburitsa kutsvedza, kunonzi creep. Kana creep yaitika, ichapedza nzvimbo yekusangana, ichakuvadza shaft kana housing, uye wear powder inopinda mubearing, zvichikonzera kupisa, kudedera uye kukuvara. Kupindira kwakanyanya kuchaita kuti dhayamita yekunze ive diki kana dhayamita yemukati yakakura yering yemukati, izvo zvichaderedza kuvhurika kwemukati mebearing. Pamusoro pezvo, kurongeka kwejometri yekugadzirisa shaft neshell kuchakanganisawo kurongeka kwekutanga kwebearing ring, nokudaro zvichikanganisa mashandiro ebearing.

1.1 Kusarudzwa kweFit 1.1.1 Mhando yemutoro uye kusarudzwa kwefit zvinotsanangurwa zvichienderana negwara rekutakura bearing uye mamiriro ekutenderera kwemhete dzemukati nedzekunze, kazhinji zvichireva Tafura 1. Tafura 1 uye load and load bearing rotating conditions mifananidzo ine inner ring: negative turns: static load direction: fixed inner ring spinning load inner ring, outer ring static load INOSHANDISA interference fit (interference fit) outer ring: available running fit (clearance) inner ring: static negative denderedzwa: the rotation direction of the load, and the outer ring and spin inner ring: negative turns: static load direction: fixed inner ring static load inner ring, outer ring spinning load available running fit (clearance) outer ring: INOSHANDISA interference fit (interference fit) inner ring: static negative denderedzwa: rotary load: with the inner ring spinning panguva imwe chete. 2) Inokurudzirwa fit Kuti usarudze fit yakakodzera, bearing load hunhu, saizi, tembiricha, bearing installation, kubviswa kwemamiriro akasiyana-siyana. Kana bearing yaiswa paganda rakatetepa uye hollow shaft, huwandu hweinterference hunofanira kunge hwakakura kupfuura hweakajairika. Goko rakaparadzaniswa rinogona kukanganisa zviri nyore mhete yekunze yebheyaringi, saka mhete yekunze inofanira kushandiswa nokungwarira kana paine kurongeka kwakasimba. Kana paine kudedera kukuru, mhete yemukati nemhete yekunze zvinofanirwa kushandisa kurongeka kwakasimba.

Semuenzaniso, kuiswa kwechikamu chefudzi kana kunyatsojeka kusina kunaka, mhete dzemukati nedzekunze dzicharerekera. Kuwedzera kune bearing load, pamwe chete nemutoro wakanyanya kusimba pakupera, hupenyu hwekuneta kwebearing huchaderedzwa, uye zvakanyanya kuipa, ichava chikonzero chekukuvadzwa kwekeji uye sintering. Pamusoro pezvo, deformation yegoko nekuda kwemutoro wekunze haisi yakakura. Zvakakosha kutsigira zvizere kuomarara kwebearing. Kana kuomarara kwakakwira, ruzha nekupararira kwemutoro kwebearing kuri nani.

Mumamiriro ezvinhu ekushandisa, kugadzira michina yekutenderedza magumo kana kunyatsofinha kunogona kuitwa. Zvisinei, kana paine zvinodiwa zvakasimba zvekutenderera uye ruzha uye mamiriro emutoro akanyanya kuoma, kukuya kwekupedzisira kunofanira kushandiswa. Kana mabheyaringi anopfuura maviri akarongeka mudzimba dzese, nzvimbo dzekusangana kwedzimba dzinofanira kugadzirwa kuti dzive nemuchina uye dziboorwe. Mumamiriro ezvinhu ekushandisa, shaft, housing usahihi uye kupera zvinogona kunge zvakaratidzwa muTafura 4 pazasi.

Kubviswa kwemukati kwebearing kunoreva huwandu hwekufamba kana mhete yemukati kana yekunze yebearing yasimbiswa bearing isati yaiswa pashaft kana bhokisi rebearing, uye ipapo divi risina kugadziriswa rinofambiswa munzira yeradial kana axial. Zvichienderana negwara rekufamba, rinogona kukamurwa kuita radial clearance uye axial clearance. Pakuyera clearance yemukati yebearing, kuitira kuti kukosha kwakayerwa kurambe kwakasimba, mutoro wekuyedza unowanzo shandiswa paring. Naizvozvo, kukosha kwekuyedza kwakakura kupfuura kukosha kweclearance chaiyo, kureva kuti, huwandu hwekuwedzera kwe elastic deformation hunokonzerwa nekushandisa mutoro wekuyedza. Kukosha chaiko kwebearing internal clearance kunoratidzwa muTafura 4.5. Kuwedzera kweclearance kunokonzerwa ne elastic deformation iri pamusoro apa kunogadziriswa. Kushanduka kwe elastic kwema roller bearings hakuna kukosha. Tafura 4.5 yekubvisa simba re radial clearance test load correction (deep groove ball bearing) mayuniti: um nominal bearing model dhayamita d (mm) (N) clearance test load correction over to C2 C3 C4 C510 ordinary (kusanganisira) 18 24.549 147 3 ~ 4 4 ~ 5 6 ~ 8 45 8 4 6 9 Kubvumbi 9 Kubvumbi 6 92.2 kusarudzwa kwebearing clearance bearing running clearance, nekuda kwe bearing fit uye tembiricha mutsauko pazvikonzero zvemukati nekunze, kazhinji kacho idiki pane clearance yekutanga. clearance yekushanda ine hukama hwakanyanya nehupenyu hwebearing, kukwira kwetembiricha, kudedera uye ruzha, saka inofanira kuiswa kune mamiriro akakodzera.

Panyaya yedzidziso, kana bearing iri kushanda, ne clearance iri kumhanya zvishoma, hupenyu hwe bearing hwakanyanya. Asi zvakaoma kuchengetedza clearance iyi. Nekuchinja kwemamiriro ebasa, clearance iri mu bearing ichawedzera zvakafanana, izvo zvinotungamira kudzikira kukuru kwehupenyu hwe bearing kana kugadzirwa kwekupisa. Nokudaro, clearance yekutanga ye bearing inowanzo kuve yakakura zvishoma pane zero. Mufananidzo 2 musiyano we bearing radial clearance 2.3 Maitiro ekusarudza Bearing clearance Panyaya yedzidziso, bearing life inowedzerwa kana paine clearance iri kushanda zvishoma pasi pemamiriro ekushanda akachengeteka. Asi mukuita, zvakaoma zvikuru kuchengetedza mamiriro aya akanaka. Kana mamwe mamiriro ebasa achinja, clearance iri mu negative ichawedzera, zvichikonzera kudzikira kukuru kwehupenyu hwe bearing kana kupisa. Naizvozvo, kana clearance yekutanga ichiwanzosarudzwa, clearance yekushanda inofanirwa kunge yakakura zvishoma pane zero.

Kune mabheyaringi pasi pemamiriro ezvinhu akajairwa, kurongeka kwemitoro yakajairika kuchashandiswa. Kana kumhanya netembiricha zviri zvakajairika, nzvimbo yakajairika inofanira kusarudzwa kuti iwane nzvimbo yakakodzera yekushanda.
