Funda ngezindinganiso zokususa i-radial clearance zama-rolling bearings

UkuthwalaIsikhala sibhekisela enanini lokunyakaza lapho i-bearing ingafakwanga ku-shaft noma ebhokisini lokuthwala, uhlangothi olulodwa lwendandatho yangaphakathi noma indandatho yangaphandle luqinisiwe, bese uhlangothi olungagxilile luhamba nge-radially noma nge-axial. Ngokwesiqondiso sokunyakaza, lungahlukaniswa nge-radial clearance kanye ne-axial clearance. Isikhala sibaluleke kakhulu futhi ekusebenziseni ama-bearing.

Ukuhlukaniswa kwe-radial kwe-rolling bearing kuyisilinganiso se-arithmetic sebanga le-radial lendandatho yangaphandle maqondana nendandatho yangaphakathi kusukela endaweni eyodwa yomkhawulo we-radial eccentric kuya endaweni yomkhawulo ephambene esimweni esingalayishwanga kusengaphambili. Ngokusho kwe-GB/T307.1-2018 ejwayelekile kazwelonke, ukuhlukaniswa kwe-radial kuhlukaniswe ngamagremu amahlanu: amakhulu, aphakathi nendawo, amancane, amancane kakhulu kanye namancane kakhulu. Amanani okuhlukaniswa kwebanga ngalinye lebanga alandelayo: C2, CN, C3, C4, C5; C0, C1, C2, CN; Amancane ku-C0, C1, C2, CN; Okuncane kakhulu yi-C0 kanye ne-C1; Amancane kakhulu yi-C0 kanye ne-C1, lapho i-C0 imelela ukuhlukaniswa okuncane kanti i-C5 imelela ukuhlukaniswa okukhulu.

 

Ngaphezu kwalokho, indinganiso ye-ISO kanye nendinganiso ye-American ABMA nazo zinamabanga ahlukene okuvunyelwa kwe-radial. Indinganiso ye-ISO ihlukaniswe ngamabanga amane: i-N, i-P, i-M, kanye ne-K, kanti indinganiso ye-American ABMA ihlukaniswe ngamabanga amahlanu: i-C1, i-C2, i-C3, i-C4, kanye ne-C5. Uma ukhetha ama-bearings, kubalulekile ukucacisa izindlela ezisetshenziswayo ukunquma isigaba sokuvunyelwa kwe-radial.

 

Ukuhlukaniswa kwe-radial kwebheri kuthinta ngqo impilo yayo yesevisi, ukwenyuka kwezinga lokushisa, umsindo nokudlidliza kanye nezinye izakhiwo. Ukuhlukaniswa okweqile kungaholela empilweni yebheri emfushane, ukunemba okuphansi kokujikeleza, ukudlidliza nomsindo; Uma indawo incane kakhulu, kulula ukubangela ukungqubuzana nokushisa kwande, ukwenyuka kwezinga lokushisa kwande, futhi kuholele nasekukhiyweni kwamabheri. Ngakho-ke, lapho ukhetha indawo yebheri, kubalulekile ukucabangela ukuqina kwebheri kanye nokulingana kweshafu, umehluko wokushisa obangelwa ukusebenza kwebheri, kanye nomehluko ku-coefficient yokwandisa yebheri kanye neshafu.

Okuningi amabheringiulwazi, sicela uxhumane nathi:
