Sibe kweli shishini ixesha elide, ukunyamezela ukunyamezela phakathi kokuthwala kunye ne-shaft, kunye nokunyamezela ukunyamezela phakathi kokuthwala kunye nomngxuma, kuye kwahlala kukwazi ukufezekisa umsebenzi kunye ne-clearance encinci, kwaye kunjalo. kulula ukudibanisa kunye nokuqhaqha. Nangona kunjalo, ezinye iindawo zisafuna ukuchaneka okuthile.
Ukunyamezelana okufanelekileyo sisimbuku sokunyamezela umngxuma kunye ne-shaft eyenza ukulingana. Ixabiso lenguquko evumela ukucaciswa kokuphazamiseka.
Ubungakanani bommandla wokunyamezela kunye nendawo yokunyamezela umgodi kunye ne-shaft yenza ukunyamezela okufanelekileyo. Ubungakanani bomngxuma kunye ne-shaft fit tolerance ibonisa ukuchaneka okufanelekileyo komngxuma kunye ne-shaft. Ubungakanani kunye nendawo yomngxuma kunye ne-shaft fit tolerance zone ibonisa ukuchaneka okufanelekileyo kunye nokufaneleka kwemvelo yomngxuma kunye ne-shaft.
01 Ukukhethwa kweklasi yokunyamezelana
Iklasi yokunyamezela i-shaft okanye i-bore yezindlu ehambelana ne-bearing ihambelana nokuchaneka kokuthwala. Kwi-shaft ehambelana ne-P0 grade precision bearing, inqanaba lokunyamezela ngokubanzi yi-IT6, kunye nomngxuma wokuthwala isihlalo ngokubanzi yi-IT7. Ngezihlandlo ezineemfuno eziphezulu malunga nokuchaneka kokujikeleza kunye nokuzinza (ezifana neenjini, njl.), I-shaft kufuneka ikhethwe njenge-IT5, kwaye imbobo yokuthwala isihlalo kufuneka ibe yi-IT6.
02 Ukukhethwa kwendawo yokunyamezelana
Umthamo weradial olinganayo P wahlulwe ube yimithwalo "elula", "eqhelekileyo" kunye "nobunzima". Ubudlelwane phakathi kwayo kunye nomlinganiselo olinganisiweyo womthwalo oguqukayo we-C wokuthwala ngu: umthwalo okhanyayo P≤0.06C umthwalo oqhelekileyo 0.06C
(1) Indawo yokunyamezela umngxuma
Ngommandla wokunyamezela we-shaft apho i-radial bearing kunye ne-angular contact bearing ifakwe, bhekisa kwitheyibhile yendawo yokunyamezela ehambelanayo. Kwizihlandlo ezininzi, i-shaft iyajikeleza kwaye isalathiso somthwalo we-radial asitshintshi, oko kukuthi, xa i-ring yangaphakathi ethwele ijikeleza ngokumalunga nolwalathiso lomthwalo, ukutshintshwa okanye ukulungelelaniswa kokuphazamiseka kufuneka kukhethwe ngokubanzi. Xa i-shaft imile kwaye isalathiso somthwalo we-radial singatshintshi, oko kukuthi, xa i-ring yangaphakathi yokuthwala imile ngokumalunga nolwalathiso lomthwalo, utshintsho okanye ukulungelelaniswa okuncinci kunokukhethwa (ukukhutshwa okukhulu akuvumelekanga).
(2) Indawo yokunyamezela umngxuma weqokobhe
Ngommandla wokunyamezela kwezindlu kwiibheringi zeradial kunye ne-angular zoqhagamshelwano, bhekisa kwitheyibhile yokunyamezela ehambelanayo. Xa ukhetha, qaphela ukuphepha ukucoceka okuhambelana nezangqa zangaphandle ezijikelezayo okanye ezijikelezayo kwicala lomthwalo. Ubungakanani bomthwalo we-radial olinganayo buchaphazela ukhetho olufanelekileyo lweringi yangaphandle.
(3) Ukukhethwa kwesakhiwo sezindlu ezithwele
Ngaphandle kokuba kukho isidingo esikhethekileyo, isihlalo sokuthwala i-rolling bearing ngokubanzi samkela isakhiwo esidibeneyo. Isihlalo sokwahlula sisetyenziselwa kuphela xa indibano inzima, okanye inzuzo yendibano efanelekileyo iyona nto iqwalaselwayo, kodwa ayinakusetyenziselwa ukulingana okuqinileyo. Okanye ukulingana okuchanekileyo, okufana ne-K7 kunye nokulingana okuqinile kune-K7, okanye umngxuma wesitulo oneklasi yokunyamezela ye-IT6 okanye ngaphezulu, akusayi kusebenzisa indlu eyahlulahlulwe.
