1) Mokhoa oa ho khetha
Etsa bonnete ba hore boholo ba mojaro oho belehae ka tšehetsa ha e lula e tsitsitse (axial load Fa, radial load Fr, e phethola motsotso M).Beha boholo ba mojaro e le boleng ba sekhahla se tsitsitseng.Boleng ba sekhahla bo tsitsitseng bo tlameha ho nahana ka boima bo boholo bo neng bo le teng holima molao-motheo, bo tlamehang ho phethela mojaro o eketsehileng le mojaro oa liteko.
Etsa bonnete ba hore coefficient ea ts'ireletso ea static fs ho latela mofuta oa enjene ea mantlha (boemo ba ts'ebeliso), eo boleng ba eona ba linomoro bona tafole ea 1.
Pele u khetha mofuta oaho beleha, etsa bonnete ba hore mokhoa oa ho bala oa static reference load Fa le M.

Sheba hore na ntlha ea coordinate(Faˊ,M ˊ) e tlas'a moepa oa moeli o tsitsitseng
Ho lekola lipalo tsa matla a bolt (sheba karolo ena 5.2.4)
2) mofuta oa khetho ka static
Mokhoa oa ho bala oa moroalo o tsitsitseng oa litšupiso tsa Fa 'le M'
Mokhoa oa I(a=60°)
Palo ea khetho ea mola o le mong oa bolo ea lintlha tse 'neho belehats'ebetso ka lebelo la tšehetso ea mojaro 45 ° le 60 ° ka ho latellana.

Ebe u fumana lintlha tse peli tse kaholimo ho mothinya, e 'ngoe ea tsona e ka tlase ho lekhalo.
Mofuta o le mong oa rolara e tšelang

Mofuta oa bolo ea mela e 'meli
Palo ea khetho ea bolo ea bophara ba mela e 'meli e fapanengho beleha,ha Fr<=10%Fa, phetoho ea angle ea khatello ka har'a peisong e tlameha ho tlalehoa, ka kopo ikopanye le rona mabapi le lipalo tsa eona.
Fa'= Fa×fs

Ha u khetha rolara ea mela e meraroho beleha, bala feela ho sebelisana ha axial raceway load le nako ea ho phethola.
Fa'= Fa×fs

2) Khetho e matla
Ka kopo ikopanye le lefapha la rona la tekheniki bakeng sa ts'ebeliso ea ts'ebetso e tsoelang pele, ho potoloha ka lebelo le phahameng le lits'ebetso tse ling bakeng sa bophelo ba ts'ebeletso ea tšehetso ea rotary.
3) Ho hlahloba palo ea matla a ho beleha bolt
Boima bo boholo (ha ho na static safety factor fs) bo sebelisetsoa ho laela tšehetso ea rotary.Sheba hore na mojaro o ka tlase ho moeli oa moroalo oa liboutu tse hlokahalang;
Haeba matla a ho jara bolt a sa lekana, re ka khethaho belehahape kapa ikopanye le lefapha la rona la theknoloji.
Feme e ka fana ka tlhahisoleseling ho latela sampole ea sehlahisoa, e sebelisa static bearing capacity curve, ho latela mokhoa oa ho bala oa mofuta oa rotary bearing oa khetho ea pele.ho beleha, le theknoloji le k'hamphani ea ka ho netefatsa.Hape o ka fana ka tlhahisoleseling mabapi le ho tsamaisa rotary ho k'hamphani ea rona, ha o ntse o tsoela pele ka khetho ea moralo ke k'hamphani ea ka, ka kopo kopa 《rotary e nang le khetho ea tekhenoloji ea paramethara ea tafole 》(ho kenyeletsoa sehlomathiso A le sehlomathiso sa B tafoleng ea parametha), ebe u tlatsa ka, e le hore re ka ikokobelletsa ho uena kapele kamoo ho ka khonehang e nepahetseng rotary behang khetho moralo oa moruo le e sebetsang.
