Ukuzala

ukuphila
Ngaphansi komthwalo othile, inani lama-revolution noma amahora aukuzalaokuhlangenwe nakho ngaphambi kokugoba kubizwa ngokuthiukuzalaukuphila.
Impilo yebhere eliginqikayo ichazwa ngenani lokuphenduka (noma amahora okusebenza ngesivinini esithile): ngaphakathi kwale mpilo, ukuthwala kufanele kube nomonakalo wokuqala wokukhathala (i-spalling noma ukuhlephuka) kunoma yimaphi amaringi ayo okuthwala noma izakhi ezigingqayo. Kodwa-ke, kungakhathaliseki ukuthi kusekuhlolweni kwaselabhorethri noma ekusetshenzisweni kwangempela, kungabonakala ngokucacile ukuthi impilo yangempela yeama-bearingsngokubukeka okufanayo ngaphansi kwezimo ezifanayo zokusebenza kuhluke kakhulu. Ngaphezu kwalokho, kunezincazelo eziningana ezihlukene zokuzala "ukuphila", enye yazo ebizwa ngokuthi "impilo yokusebenza", ebonisa impilo yangempela ukuthi i-bearing ingafinyelelwa ngaphambi kokwehluleka ngenxa yokugqoka, umonakalo ngokuvamile awubangelwa ukukhathala, kodwa Kubangelwa ukuguga, ukugqwala, ukulimala kwezimpawu, njll.
Ukuze kunqunywe izinga lokuphila okuzalayo, ukuphila okuzalayo nokwethembeka kuhlobene.

Ngenxa yomehluko ekunembeni kokukhiqiza nokufana kwezinto ezibonakalayo, ngisho neqoqo elifanayo lamabheringi ento efanayo nosayizi, elisetshenziswa ngaphansi kwezimo ezifanayo zokusebenza, linesikhathi sokuphila esihlukile. Uma impilo yezibalo iyiyunithi engu-1, impilo ende yesihlobo ingamayunithi angu-4, emfishane iyunithi engu-0.1-0.2, kanti isilinganiso sempilo ende kunazo zonke kuya emfushane izikhathi ezingu-20-40. Amaphesenti angama-90 amabherengi awakhiqizi ukugqwala kwe-pitting, futhi inani lokuguquguquka noma amahora atholakalayo libizwa ngokuthi ukuphila kokulinganisa.

Ilinganiswe ngomthwalo oguqukayo
Ukuze uqhathanise umthamo wokuthwala we-bearing ngokumelene ne-pitting corrosion, lapho impilo elinganiselwe ye-ukuzalakucaciswe njengokuphenduka kwesigidi (106), ubukhulu bomthwalo obungasekelwa umthwalo oguquguqukayo olinganiselwe oyisisekelo, omelwe ngu-C.
Okusho ukuthi, ngaphansi kwesenzo somthwalo oguquguqukayo olinganiselwe C, ukwethembeka kwalolu hlobo lweukuzalaukusebenzela ama-revolutions ayisigidi (106) ngaphandle kokwehluleka kwe-pitting kungu-90%. Uma i-C inkulu, iyanda amandla okuthwala.
Ukuze uthole isilinganiso esiyisisekelo sokulayisha
1. Ukuzala kwe-radial kubhekisela kumthwalo we-radial omsulwa
2. Ama-thrust ball bearings abhekisela emithwalweni ehlanzekile ye-axial

3. I-radial thrustukuzalaisho ingxenye ye-radial ekhiqiza ukugudluka okumsulwa kwe-radial
