Mstari Mbili wa fani za Silinda
Utangulizi
Mistari miwili ya fani za roller za silinda huruhusu uhamishaji fulani wa axial kati ya shimoni na msingi wa kuzaa na inaweza kutumika kama fani zisizo na nafasi. Aina hii ya kuzaa ina faida za muundo wa kompakt, ugumu mkubwa, uwezo mkubwa wa kuzaa, deformation ndogo baada ya upakiaji. , nk, hasa yanafaa kwa msaada wa spindle chombo cha mashine.
Vipengele na Faida
● Uwezo wa juu wa kubeba mizigo
Kwa sababu ya safu yao ya pili ya rollers, fani za roller za safu mbili za silinda zinafaa kwa mizigo nzito ya radial.
● Msuguano wa chini (Mwisho wa roller / eneo la mawasiliano la flange)
Muundo wa flange wazi , pamoja na muundo wa mwisho wa rola na umaliziaji wa uso, hukuza uundaji wa filamu ya vilainisho hivyo kusababisha msuguano wa chini na uwezo wa juu wa kubeba mzigo wa axial.
● Maisha marefu ya huduma
Wasifu wa rola ya logarithmic hupunguza mikazo ya ukingo katika mguso wa rola/mbio na unyeti wa mpangilio mbaya na mgeuko wa shimoni.
● Kuimarishwa kwa uaminifu wa uendeshaji
Upeo wa uso kwenye nyuso za mawasiliano za rollers na mbio za mbio husaidia uundaji wa filamu ya lubricant ya hydrodynamic.
● Inaweza kutenganishwa na inaweza kubadilishwa
Vipengele vinavyoweza kutenganishwa vya fani za roller za safu mbili za silinda zinaweza kubadilishwa.Hii hurahisisha kuweka na kushuka, pamoja na ukaguzi wa matengenezo.
● Uwezo wa kasi ya juu
Miundo ya ngome inafaa kwa kasi ya juu, kasi ya haraka na mizigo ya kilele.
Maombi
NUU safu mbili za fani za roller za silinda zinaweza kutumika katika zana za mashine, magari, motors, gearboxes za kupunguza, skrini za vibrating, nk.
Matumizi
Kuzaa kwa roller ya safu mbili ya silinda inaweza kubeba mzigo mkubwa wa du katika mwelekeo wa radial.Inaruhusu safu mbili za rollers za DAO katika kuzaa na kasi ya juu kupangwa kwa njia ya msalaba.Mzunguko wa kushuka kwa kasi wakati wa mzunguko ni mara mbili zaidi kuliko ile ya kuzaa mstari mmoja, na amplitude imepunguzwa kwa 70%.
Kuna aina mbili za fani katika matumizi ya kawaida: NN30/W33 na NN30K/W33 mfululizo.Msururu wa NNU49/W33 na NNU49K/W33 wenye pete ya nje yenye makali, pete ya ndani inaweza kutenganishwa, NN30K/W33 na NNU49K/W33 mfululizo wa pete ya ndani ni mashimo yaliyofungwa (taper 1:12), ambayo yanaoana na jarida la conical la spindle. .Axial harakati ya pete ya ndani inaweza kufanya pete ya ndani kupanua ili kupunguza kuzaa kibali na hata pretighten kuzaa.
fani za vijito vya cylindrical kawaida hupakiwa na joto, na kifafa cha kuingilia kati hutumika kupunguza kibali cha kuzaa au kufikia madhumuni ya upakiaji mapema.Behu za mfululizo za NNU49 zenye pete ya ndani inayoweza kutenganishwa kwa ujumla hutengenezwa kwa mashine kwenye barabara ya mbio baada ya kusakinisha spindle kwenye pete ya ndani ili kupata usahihi wa hali ya juu wa mzunguko wa spindle.
