ubomi
Phantsi komthwalo othile, inani le revolutions okanye iiyure ukuba aukuzalaamava phambi kokuba pitting kwenzeke kuthiwaukuzalaubomi.
Ubomi bebherethi eqengqelekayo buchazwa ngenani leenguqu (okanye iiyure zokusebenza ngesantya esithile): ngaphakathi kobu bomi, ukuthwala kufuneka kube nomonakalo wokuqala wokudinwa (i-spalling okanye i-chipping) kuyo nayiphi na ikhonkco layo lokuzala okanye izinto ezijikelezayo. Nangona kunjalo, nokuba kuvavanyo lwebhubhoratri okanye kusetyenziso lokwenene, kunokubonwa ngokucacileyo ukuba ubomi bokwenyaniiibheringikunye nenkangeleko efanayo phantsi kweemeko zokusebenza ezifanayo zihluke kakhulu. Ukongeza, kukho iinkcazo ezininzi ezahlukeneyo zokuzala "ubomi", enye yazo ibizwa ngokuba "ubomi bokusebenza", nto leyo ebonisa ubomi bokwenyani obunokubufumana ngaphambi kokuba ukusilela kube ngenxa yokunxiba, umonakalo awubangwa ukudinwa, kodwa Kubangelwa kukuguga, ukubola, umonakalo wetywina, njl.
Ukuze unqume umgangatho wokuphila ubomi, ukuthwala ubomi kunye nokuthembeka kuhambelana.
Ukuze uthelekise ukuthwala umthamo yebheringi nxamnye pitting umhlwa, xa ubomi rated yeukuzalakuxelwa ukuba sisigidi seerevolutions (106), owona mthwalo uphezulu unokuxhaswa ngowona mthwalo ulinganiselweyo osisiseko, omelwe nguC.
Oko kukuthi, phantsi kwesenzo somthwalo oguqukayo olinganisiweyo C, ukuthembeka kolu hloboukuzalaukusebenza kwisigidi revolutions (106) ngaphandle pitting ukusilela yi 90%. Inkulu i-C, iphezulu umthamo wokuthwala.
Kwinqanaba lomthwalo oguqukayo osisiseko
1. Ukuthwala i-radial kubhekiselele kumthwalo ococekileyo we-radial
2. Iibheringi zebhola ezithrust zibhekisa kwimithwalo ye-axial ecocekileyo

Ngenxa yomahluko kwimveliso echanekileyo kunye nokufana kwezinto eziphathekayo, kunye nebhetshi enye yeebheringi zezinto ezifanayo kunye nobukhulu, obusetyenziswe phantsi kweemeko zokusebenza ezifanayo, zinexesha elihlukeneyo lobomi. Ukuba ubomi bezibalo buyiyunithi ye-1, ubomi obude obude buziiyunithi ezi-4, i-shortest yi-0.1-0.2 iyunithi, kunye nomlinganiselo wexesha elide kubomi obufutshane ngamaxesha angama-20-40. I-90% yeebheringi ayivelisi umhlwa, kwaye inani leenguqu okanye iiyure ezifunyenweyo zibizwa ngokuba yi-bearing rating ubomi.
Ukuze uthelekise ukuthwala umthamo yebheringi nxamnye pitting umhlwa, xa ubomi rated yeukuzalakuxelwa ukuba sisigidi seerevolutions (106), owona mthwalo uphezulu unokuxhaswa ngowona mthwalo ulinganiselweyo osisiseko, omelwe nguC.

2. Iibheringi zebhola ezithrust zibhekisa kwimithwalo ye-axial ecocekileyo
3. I-radial thrustukuzalaibhekisa kwilungu leradial elivelisa ukufuduswa kweradial okumsulwa
