Ama-roller enaliti ama-bearings angama-cylindrical roller bearings.Ngokuphathelene nobubanzi bawo, ama-roller mancane futhi made.Le roller ibizwa ngokuthi i-needle roller.Nakuba inesigaba esincane esiphambanayo, ukuthwala kusenamandla aphezulu okuthwala, ngakho kufanelekile ikakhulukazi ngezikhathi ezinendawo elinganiselwe ye-radial.

I-contour surface ye-naliti roller ifinyezwa kancane endaweni yokugcina eseduze.Inaliti kanye nemiphumela yokulungiswa komugqa wokulandelela ingagwema ukulimaza ukucindezeleka konqenqema.Ngaphezu kwekhathalogu, amabhere angasetshenziselwa ubunjiniyela obujwayelekile, njengalezi: amabhova enaliti enaliti adonsayo avuliwe (1), amabheringi enaliti adonselekayo avaliwe (2), amabheringi enaliti anendandatho yangaphakathi (3) nangaphandle i-inner ring inaliti ye-roller bearings (4), i-SKF ingahlinzeka ngezinhlobo ezahlukene zamabhodlela enaliti enaliti, okuhlanganisa: 1, ama-needle roller cage assemblies 2, ama-bearings enaliti enaliti ngaphandle kwezimbambo 3, ama-bearings enaliti azimele 4, inhlanganisela Inalithi / ibhola ama-bearings 5, inaliti ehlanganisiwe / i-thrust ball bearings 6, inaliti ehlanganisiwe / i-cylindrical roller thrust bearings.

Ama-bearings enaliti enaliti edwetshiwe

Ama-roller enaliti enkomishi edwetshiwe angamabhodlela enaliti anendandatho yangaphandle enesitembu esincane.Isici sayo esiyinhloko ukuphakama kwesigaba esiphansi kanye nomthamo omkhulu womthwalo.Isetshenziselwa ikakhulukazi ukuthwala ukucushwa ngesakhiwo esihlangene, intengo eshibhile, futhi imbobo yangaphakathi yebhokisi elithwalayo ayikwazi ukusetshenziswa njengomgwaqo womhlangano wekheji yenaliti.Ama-bearings nama-bearing housings kufanele afakwe endaweni yokuphazamiseka.Uma imisebenzi ye-axial positioning efana namahlombe ebhokisi kanye namasongo okugcina ingashiywa, khona-ke ukubhoboza ebhokisini lokuthwala kungenziwa kube lula kakhulu futhi ukonga.

Ama-roller enaliti enkomishi edwetshiwe afakwe ekugcineni kwe-shaft avulwe nhlangothi zombili (1) futhi avalwe ohlangothini olulodwa (2).Ubuso besiphetho seringi yangaphandle evaliwe bungamelana namandla amancane aqondisayo e-axial.

Ama-roller enaliti enkomishi edwetshiwe ngokuvamile awanayo iringi yangaphakathi.Lapho ijenali ingeke iqiniswe futhi igaywe, iringi yangaphakathi esohlwini lwetafula ingasetshenziswa.Iringi yangaphandle yensimbi eqinile yeringi yenkomishi yenaliti edonsayo ayinakuhlukaniswa nomhlangano wekheji lenaliti.Isikhala samahhala sokugcina okokugcoba singanweba isikhawu sokuphinda kugcotshwe.Ama-bearings ngokuvamile aklanywa ngomugqa owodwa.Ngaphandle kochungechunge olubanzi lwama-bearings 1522, 1622, 2030, 2538 kanye no-3038, afakwe imihlangano emibili yekheji lezinaliti.Iringi yangaphandle ethwele inembobo yokugcoba.Ngokuya ngezidingo zomsebenzisi, wonke ama-roller enaliti adwetshwe umugqa owodwa anobubanzi be-shaft obukhulu noma obulingana no-7mm angahlonyiswa ngamasongo angaphandle (isijobelelo sekhodi AS1) esinezimbobo zokugcoba.

Izinaliti ze-roller ezidwetshiwe zenkomishi ezinophawu lwamafutha

Lapho ama-seal kawoyela engakwazi ukufakwa ngenxa yezinkinga zesikhala, ama-roller bearings enaliti (3 kuya ku-5) anophawu lwamafutha agxivizwe iringi yangaphandle anganikezwa izindawo ezivulekile noma ezivaliwe.Lolu hlobo lokuthwala lufakwe uphawu lukawoyela wokukhuhlana we-polyurethane noma irabha yokwenziwa, egcwele i-lithium-based grease enokusebenza okuhle kokulwa nokugqwala, ofanele izinga lokushisa lokusebenza -20 kuya ku-+100 ° C.

Iringi yangaphakathi yebheringi evalwe ngamafutha ibanzi ngo-1mm kuneringi yangaphandle.Lokhu kuvumela ukuthwala ukuqinisekisa ukuthi uphawu lwamafutha lusebenza kahle lapho i-shaft ine-displacement encane ehlobene nebhokisi elithwalayo, ukuze ukuthwala kungangcoliswa.Iringi yangaphakathi enezimbobo nayo inezimbobo zokugcoba, ezingaphinde zigaywe yiringi yangaphandle noma iringi yangaphakathi ngokwezidingo zokucushwa kokuthwala.
