Ukucaciswa kwe-Axial kwebhereyi

 

Okubizwa ngokuthi ibhereukususwa kubhekisela enanini lokunyakaza laphoibhereayifakwanga emshafini noma endlini yokubeka izinsimbi, ilungisa uhlangothi olulodwa lwendandatho yangaphakathi noma indandatho yangaphandle, bese yenza uhlangothi olungagxili lunyakaze ngemisebe noma nge-axial. Ngokwesiqondiso sokunyakaza, ingahlukaniswa ngokuthi i-radial clearance kanye ne-axial clearance.

Ubukhulu bendawo yokuvula (ebizwa ngokuthi indawo yokuvula yokusebenza) ngesikhathi sokusebenza bunomthelela empilweni yokukhathala okugoqekayo, ukwenyuka kwezinga lokushisa, umsindo, ukudlidliza kanye nezinye izakhiwo zebhereyi.

Uma kulinganiswa ukuvuleka kwebheri, kubizwa ngokuthi ukuvuleka kwebheri, okubhekisela enanini lokunyakaza lapho ibheri ingafakwanga emshafini noma endlini yebheri, kulungiswa uhlangothi olulodwa lwendandatho yangaphakathi noma indandatho yangaphandle, bese kwenze uhlangothi olungagxili lunyakaze ngemisebe noma nge-axial. Ngokwesiqondiso sokunyakaza, lungahlukaniswa nge-radial clearance kanye ne-axial clearance.

Ubukhulu bendawo yokuvula (ebizwa ngokuthi indawo yokuvula yokusebenza) ngesikhathi sokusebenza bunomthelela empilweni yokukhathala okugoqekayo, ukwenyuka kwezinga lokushisa, umsindo, ukudlidliza kanye nezinye izakhiwo zebhereyi.

Uma kulinganiswa ukuvuleka kwe-aibhere, umthwalo wokulinganisa ocacisiwe uvame ukusetshenziswa kubhereyi ukuze kutholakale inani elilinganisiwe elizinzile.

Ngenxa yalokho, inani elilinganisiwe likhulu kune-clearance yangempela (eyaziwa ngokuthi i-theoretical clearance), okungukuthi inani le-elastic deformation ngenxa yomthwalo olinganisiwe liyakhuphuka.

Kodwa-ke, uma kukhulunywa ngama-roller bearings, lokhu kuguquguquka kwe-elastic akunakwa ngenxa yenani lakhona elincane.

Ukucaciswa kwangaphakathi kwebhereyi ngaphambi kokufakwa kuvame ukuvezwa ngokwemibandela yokucaciswa kwethiyori.

Ukukhetha imvume

Isikhala ngemva kokukhipha inani lokwandiswa noma ukufinyela kwendandatho ngenxa yokuphazamiseka okulingana lapho ibhere lifakwe kushafu noma endlini kusukela ekusithekeni kwethiyori kubizwa ngokuthi "isikhala sokusibekela".

 

Isikhala ngemva kokwengeza noma ukususa umehluko wobukhulu ngenxa yomehluko wokushisa ngaphakathi kwebhereyitha sibizwa ngokuthi "isikhala esisebenzayo".

Ibhereyi ifakwa nge-clearance uma ibekwa ngaphansi komthwalo othile ngomshini, okungukuthi, i-clearance esebenzayo yengezwa ekuguqukeni kwe-elastic okubangelwa umthwalo we-bearing, ngakho-ke ibizwa ngokuthi "i-working clearance".　

 

Uma indawo yokusebenza iphansi kancane, isikhathi sokukhathala sebhereyi siphezulu kakhulu, kodwa ngokwanda kwesikhala esiphansi, isikhathi sokukhathala siyancipha kakhulu. Ngakho-ke, lapho ukhetha indawo yokusebenza iphansi, ngokuvamile kuyalulekwa ukwenza indawo yokusebenza iphansi ibe yi-zero noma ibe yinhle kancane.

Ngaphezu kwalokho, uma kudingeka ukuthuthukisa ukuqina kwebhereyi noma ukunciphisa umsindo, indawo yokusebenza kufanele ibe yimbi kakhulu, futhi uma izinga lokushisa lebhereyi liphezulu kakhulu, indawo yokusebenza kufanele ibe yinhle kakhulu, njll., futhi kufanele kwenziwe ukuhlaziywa okuqondile ngokwezimo zokusetshenziswa.

 

Umqondo wokususwa kwama-bearings ajikelezayo

1. Imvume yakudala

Ukususwa kwe-bearing kusesimweni esikhululekile ngaphambi kokufakwa kwe-bearing. Ukususwa kokuqala kunqunywa ukucubungula nokuhlanganiswa kwesitshalo sokukhiqiza.

 

2. Ukufakwa kwesikhala

Ibizwa nangokuthi indawo yokubopha, okuyindawo lapho kufakwa khona i-bearing, shaft kanye nesihlalo sokubopha kodwa kungakasebenzi. Ngenxa yokuphazamiseka kokufakwa, kungaba indandatho yangaphakathi iyakhuliswa, indandatho yangaphandle iyancishiswa, noma kokubili, indawo yokufaka incane kunendawo yokuqala.

 

3. Imvume yokusebenza

Uma i-bearing isesimeni sokusebenza, ukukhuphuka kwezinga lokushisa kwendandatho yangaphakathi kukhulu kakhulu, kanti ukwanda kokushisa kukhulu kakhulu, ukuze i-bearing clearance inciphe; Ngesikhathi esifanayo, ngenxa yomthwalo, ukuguquguquka kwe-elastic kwenzeka lapho kuxhumana khona into egingqikayo kanye nomgwaqo wokugijima, okwandisa i-bearing clearance. Ukuthi i-operation clearance ye-bearing inkulu noma incane kune-operation clearance kuncike emphumeleni ohlangene walezi zici ezimbili.
