I-Double Row Cylindrical Roller Bearings
Izici
Amarola angama-cylindrical amarowu amabili:
Uhlobo lwe-NN: iringi yangaphakathi inezimbambo, futhi iringi yangaphandle ayinazimbambo. Indandatho yangaphandle kanye nomhlangano wangaphakathi kungafakwa ngokuhlukana, okungakhawuleli ukususwa kwe-axial ye-shaft noma indlu, futhi ayikwazi ukuthwala umthwalo we-axial. Uma kuqhathaniswa nomugqa owodwa one-cylindrical roller enosayizi ofanayo we-radial, ingakwazi ukumelana nemithwalo emikhulu ye-radial. Isakhiwo sihlangene, i-deformation ngaphansi komthwalo incane, futhi ifaneleka ngokukhethekile ukusekelwa kwe-spindle yethuluzi lomshini.
Thayipha i-NN...K:
Isakhiwo siyafana nohlobo lwe-NN, kodwa imbobo yangaphakathi yokuthwala i-tapered, elungele ukulungiswa kahle kwe-radial clearance ye-bearing futhi ilungele ukuhlanganisa nokuhlakaza. Lolu hlobo lokuthwala lusetshenziswa kakhulu ku-shaft eyinhloko yethuluzi lomshini futhi lufakwe ku-shaft tapered. I-radial clearance ilungiswa ngenani elicindezelayo leringi yangaphakathi.
Izinhlobo NNU, NNU…K:
Iringi yangaphandle inezimbambo kanti iringi yangaphakathi ayinazimbambo. Kunezinhlobo ezimbili zezimbobo ze-cylindrical nezimbobo ze-conical. Ayikhawuleli ukufuduka kwe-axial ye-shaft noma izindlu futhi ayikwazi ukuthwala imithwalo ye-axial. Uma kuqhathaniswa nomugqa owodwa one-cylindrical roller enosayizi ofanayo we-radial, ingakwazi ukumelana nemithwalo emikhulu ye-radial.
Thayipha i-NNCF:
Iringi yangaphakathi inezimbambo ezintathu kanti iringi yangaphandle inobambo olulodwa lokuma kwe-axial ohlangothini olulodwa. Iringi yangaphandle ifakwe indandatho ebambayo ngakolunye uhlangothi lombambo ukuze igcine isiqeshana esisodwa.
Uhlobo lwe-NNCL:
Iringi yangaphakathi inezimbambo ezintathu, iringi yangaphandle ayinazimbambo, futhi kukhona izindandatho zokumisa ezinhlangothini zombili ukuze zibe ibhere elingenakuhlukaniswa.
I-NNCS:
Iringi yangaphakathi inezimbambo ezintathu, iringi yangaphandle ayinazimbambo, futhi kukhona iringi yokukhiya emaphakathi phakathi nendandatho yangaphandle, eba yibhere elingenakuhlukaniswa. I-shaft kanye nesihlalo esithwalayo kuvumela ukufuduka okuthile kwe-axial futhi kungasetshenziswa njengendlela yokuphela yamahhala.
Izinhlelo zokusebenza
Ama-bearings anjalo asetshenziswa kakhulu kuma-spindles amathuluzi omshini, izinjini ezivuthayo zangaphakathi, izinjini zegesi, izinciphisi, imishini yokulayisha nokuthulula kanye nemishini ehlukahlukene yezimboni.
Ibanga losayizi:
Amarola angama-cylindrical amarowu amabili:
Ububanzi bosayizi wangaphakathi: 50mm ~ 1500mm
Ububanzi bosayizi bangaphandle: 80mm ~ 2300mm
Ububanzi besayizi: 23mm ~ 800mm
Ukubekezelela: Ukunemba komkhiqizo kunebanga elijwayelekile, ibanga le-P6, ibanga le-P5, kanye nemikhiqizo yebanga le-P4 nayo ingacutshungulwa uma umsebenzisi enezidingo ezikhethekile.
Ukususwa kwe-radial
Umkhiqizo ojwayelekile we-double rowu eyi-cylindrical roller bearing unesethi engu-1 yemvume, futhi ama-cylindrical bore bearings nawo anganikeza amasethi angu-2 noma 3 okususwa.
Ama-tapered bore bearings nawo ayatholakala ngamasethi ama-2 wokuvunyelwa.
Amabherele ane-radial clearance amakhulu noma amancane kunevelu evamile nawo angakhiqizwa ngokuya ngezidingo zomsebenzisi.
ikheji
Amakheji angama-cylindrical roller anemigqa ekabili ngokuvamile asebenzisa amakheji ethusi anomshini, futhi ngezinye izikhathi amakheji enayiloni ayatholakala.
Ikhodi yokwengeza:
D ukuhlukanisa ukuzala.
Ukusetshenziswa okubhanqiwe okuhambisana nokuhlukaniswa kwemigqa emibili ye-DR
E Izinguquko zedizayini yangaphakathi, isakhiwo esiqinisiwe. (Usayizi wendlela yomjaho uvumelana nezinga likazwelonke lamanje (uhlobo oluthuthukisiwe), ububanzi berola,
Ubude bunyusiwe uma kuqhathaniswa nohlobo olungaqinisiwe. )
