Iyini isilinganiso somthwalo omile kanye nesilinganiso somthwalo oguqukayo sebhereyi?

 

Uma sibuza mayelanaibhereimodeli, sivame ukubona izinketho ezimbili, i-Cr kanye ne-Cor, i-Cr ibhekisela kumthwalo oguquguqukayo we-bearing, i-Cor ibhekisela kumthwalo oqinile we-bearing. Ngakho-ke iyini isilinganiso somthwalo oqinile kanye nesilinganiso somthwalo oguquguqukayo we-bearing? Yibuphi ubudlelwano nomehluko phakathi kwalokhu okubili?

Amapharamitha amathathu ayisisekelo avame ukusetshenziswa ekwakhiweni kwama-rolling bearings yilezi: umthwalo oyisisekelo oguquguqukayo we-Cr (radial) noma i-Ca (axial) ohlangabezana nezidingo zempilo ethile yokukhathala; Amandla ayisisekelo alinganiselwe e-static Cor (radial) noma i-Coa (axial) ahlangabezana nezidingo ezithile zamandla aqinile kanye nesivinini esiphezulu se-No, esilawula ukuguguleka kwama-bearings.

 

Kuyiniibhereisilinganiso somthwalo omile?

 

Isilinganiso esiyisisekelo somthwalo omile wama-rolling bearings (i-radial Cor, i-axial Coa) sibhekisela kumthwalo we-radial ocatshangelwayo noma umthwalo we-axial static ophakathi olingana nomthwalo omkhulu we-bearing lapho ukucindezeleka okuthile kokuthintana kubangelwa ukucindezeleka okuthile kokuthintana esikhungweni sokuxhumana se-rolling element kanye nomgwaqo wokugijima.

 

Kuma-radial bearing, umthwalo oqinile olinganiselwe ubhekisela kumthwalo we-radial, ku-radial thrust bearing (i-angular contact ball bearing) ubhekisela engxenyeni ye-radial yomthwalo elayisha umzila wokugijima engxenyeni yesigamu se-bearing, kanti ku-thrust bearing, ubhekisela kumthwalo we-axial ophakathi.

 

Okusho ukuthi, isilinganiso somthwalo omile oyisisekelo we-radial kanye nesilinganiso somthwalo omile oyisisekelo we-axial we-bearing kubhekisela kumthwalo omkhulu kakhulu i-bearing engawuthwala uma imile noma ijikeleza.

 

Umthamo wokuthwala umthwalo wama-deep groove ball bearings lapho kumile noma kujika kancane (isivinini n≤10r/min) ulinganiselwe umthwalo omile.

 

Kuyiniibhereisilinganiso somthwalo oguqukayo?

 

Isilinganiso somthwalo oguquguqukayo we-bearing sibhekisela ku: i-rolling bearing ingathwala umthwalo we-radial oqhubekayo (umthwalo we-axial oqhubekayo), ngaphansi kwesenzo sempilo eyisisekelo elinganisiwe ye-100W rpm, umthwalo oguquguqukayo olinganiselwe we-bearing ubonisa ikhono le-bearing lokumelana nokukhathala okugoqayo. Isilinganiso somthwalo oguquguqukayo oyisisekelo sama-radial bearings nama-thrust bearings saziwa nangokuthi i-radial basic dynamic load rating kanye ne-axial basic dynamic load, evezwa yi-Cr kanye ne-Ca.

 

Umthamo wokuthwala umthwalo wama-groove ball bearings ngesikhathi sokujikeleza (isivinini n>10r/mim) umthwalo oyisisekelo oguquguqukayo olinganiselwe.

 

Kungani umthwalo oguquguqukayo olinganisiwe webhereyi umkhulu kunomthwalo omile olinganisiwe?

 

Umthwalo oguquguqukayo olinganiselwe ubhekisela kumthwalo osebhereni lapho impilo elinganiselwe ingu-1 million rpm. Umthwalo oqinile olinganiselwe ubhekisela ekuthintaneni phakathi kwento egingqikayo kanye nomzila wokugijima wendandatho olayishwe kakhulu lapho ibhereni liphumule, futhi isamba sokuguquguquka okungapheli kwento egingqikayo kanye nomzila wokugijima wendandatho singu-1/10,000 wobubanzi bento egingqikayo.

 

Kukhona ubudlelwano obuthile phakathi kokuphila kwenkonzo yebhereyitha kanye nomthwalo olinganisiwe webhereyitha, ngakho-ke ngaphansi kwaziphi izimo sikhetha ibhereyitha ngomthwalo olinganisiwe webhereyitha? Amaphuzu ayinhloko alandelayo:

 

Qaphela: Kwezinye izimo, usayizi webhereyi kufanele ukhethwe ngesilinganiso somthwalo omile (esichazwa njenge-Co ukuze kube lula ukuchaza) kunokuba kukhethwe ngempilo yebhereyiyi.

 

1. Ngaphansi kwesenzo somthwalo womthelela oqhubekayo noma oqhubekayo, ibhere lihlala limile.

 

2. Ngaphansi komthwalo, ibhereyi yenza kuphela ukuzulazula okuphindaphindayo noma ukunyakaza okulungisekayo.

 

3. Ngaphansi komthwalo, ijubane le-bearing liphansi kakhulu (ngaphansi kwama-revolutions ayi-10 ngomzuzu) futhi lidinga impilo emfushane kuphela. Ikakhulukazi, kulokhu, kumthwalo olinganayo onikeziwe u-P, isilinganiso somthwalo oyisisekelo oguqukayo u-C siphansi kakhulu ngokwefomula yokuphila, ukuze i-bearing ekhethiwe ingase igcwale kakhulu ekusebenzeni.

 

4. Ngaphezu komthwalo ojwayelekile wokusebenza, idinga futhi ukuthwala umthwalo onzima kakhulu, futhi ibhere liyajikeleza.

 

Kuzo zonke lezi zimo, umthwalo ongamelana nebhereyi awuxhomekile ekukhathaleni kwezinto, kodwa ezingeni lokuguquka okungapheli komgwaqo womjaho okubangelwa umthwalo.
