I-Double Row Cylindrical Roller Bearings
Isingeniso
I-double-row cylindrical roller bearings ivumela ukufuduka okuthile kwe-axial phakathi kwe-shaft kanye ne-bearing pedestal futhi ingasetshenziswa njengama-bearings angekho.Lolu hlobo lokuthwala lunezinzuzo zesakhiwo esihlangene, ukuqina okukhulu, umthamo omkhulu wokuthwala, ukuguqulwa okuncane ngemva kokulayisha. , njll., ifaneleka ngokukhethekile ukusekelwa kwe-spindle yamathuluzi omshini.
Izici Nezinzuzo
● Umthamo omkhulu wokuthwala umthwalo
Ngenxa yomugqa wabo wesibili wama-roller, ama-double cylindrical roller bearings afanele imithwalo esindayo yama-radial.
● Ukungqubuzana okuphansi (I-roller end / indawo yokuxhumana ye-flange)
Idizayini ye-flange evulekile, kanye nomklamo wokuphela kwerola kanye nokuqedwa kwendawo, ikhuthaza ukwakheka kwefilimu yokugcoba okuholela ekungqubuzaneni okuphansi kanye nomthamo ophezulu wokuthwala umthwalo we-axial.
● Impilo ende yesevisi
Iphrofayili yerola ye-logarithmic inciphisa izingcindezi zonqenqema ekuthinteni i-roller/raceway kanye nokuzwela ekungaqondisweni kahle nokuchezuka kwe-shaft.
● Ukuthembeka okuthuthukisiwe kokusebenza
Ukuqedwa okungaphezulu kokuthintana kwama-roller kanye nemigwaqo yomjaho kusekela ukwakheka kwefilimu ye-hydrodynamic lubricant.
● Ezihlukanisekayo futhi ziyashintsheka
Izingxenye ezihlukanisekayo zama-double rowu ama-cylindrical roller bearings ziyashintshana.Lokhu kusiza ukukhweza nokwehliswa, kanye nokuhlolwa kokulungisa.
● Amandla wejubane eliphezulu
Imiklamo yekheji ifanele isivinini esikhulu, ukusheshisa okusheshayo kanye nemithwalo ephakeme kakhulu.
Isicelo
I-NUU yemigqa ephindwe kabili yama-cylindrical roller bearings ingasetshenziswa kumathuluzi emishini, izimoto, izinjini, ama-gearbox okunciphisa, izikrini ezidlidlizayo, njll.
Ukusetshenziswa
Irowuni eyimigqa ekabili eyi-cylindrical roller ingathwala umthwalo omkhulu we-du ohlangothini lwe-radial.Ivumela imigqa emibili yamarola e-DAO ekuthwaleni ngesivinini esikhulu ukuthi ahlelwe ngendlela ephambanayo.Imvamisa yokuguquguquka ngesikhathi sokuzungezisa iphezulu ngokuphindwe kabili kunaleyo yokuthwala irowu elilodwa, futhi i-amplitude yehliswa ngo-70%.
Kunezinhlobo ezimbili zama-bearings asetshenziswayo okuvamile: NN30/W33 kanye ne-NN30K/W33 series.I-NNU49/W33 kanye ne-NNU49K/W33 ewuchungechunge enendandatho yangaphandle enomkhawulo, indandatho yangaphakathi ingahlukaniswa, i-NN30K/W33 kanye ne-NNU49K/W33 yochungechunge lwangaphakathi ziyizimbobo ezicijile (i-taper 1:12), ezihambisana nejenali ye-conical ye-spindle. .Ukunyakaza kwe-axial kweringi yangaphakathi kungenza iringi yangaphakathi ikhule ukuze kuncishiswe imvume yokuthwala futhi iqinise nokuthwala.
Ama-Cylindrical bore bearings ngokuvamile alayishwa ngokushisa, futhi ukulingana kokuphazamiseka kusetshenziselwa ukunciphisa imvume yokuthwala noma ukufeza inhloso yokulayisha kuqala.Amabheringi ochungechunge lwe-NNU49 anendandatho yangaphakathi ekhiphekayo ngokuvamile afakwa ngomshini emgwaqweni womjaho ngemva kokufaka i-spindle iringi yangaphakathi ukuze kutholwe ukunemba okuphezulu kokujikeleza kokuphotha.
