Ama-cylindrical roller bearrings agingle amabhele ngokuqondile ezokwamukela imithwalo ephakeme ye-radial. Izinto zabo ezihamba phambili ezihamba phambili zingama-roller we-cylindrical enza ukuxhumana ngqo nemifula. Lo mklamo uwenza baphumelele ngokukhethekile ekusingatheni amandla ahlanzekile emibhikisho, bakhonza njengezakhi ezibucayi ezinhlelweni eziningi zezicelo zezimboni. Uma kuqhathaniswa nokuzala kwebhola ngosayizi ofanayo, banikela ngomthamo ophethe umthwalo ophakeme kakhulu.

Ukwakheka kwama-cylindrical roller bearings
- Ukuhlangana okujwayelekile kwe-cylindrical roller kuqukethe izinto eziphambili ezilandelayo:
- Indandatho yangaphandle:Imvamisa ifaka izimbambo ezilungisiwe noma ama-flanges ku-One noma zombili izinhlangothi ukuhlinzeka ukuholwa kwe-axial kwama-roller.
- Indandatho yangaphakathi:Futhi imvamisa inama-Ribs noma ama-flanges wokuholwa kwe-roller. Ngokuya nge-design, indandatho yangaphakathi ingaba ukuhlanganiswa ngama-Ribs noma nge-Stupable (lula ukukhwela).
- I-Cylindrical Rollers:Izinto zokuqalisa ngokucophelela-komhlaba Ubude be-roller buvame kakhulu ngaphansi kobubanzi babo.
- I-Cage (retainer):Ihlukanisa ama-roller ngokulinganayo, ibavimbela ukuthi bayihlikihle komunye nomunye, futhi ibakhombisa kahle ngaphakathi kwemijaho. Izinto zekheji zifaka insimbi, ithusi, noma ama-polymers (e.g., polyamide / nylon).
Izici ze-Cylindrical Roller Bearnings
- Umthamo ophezulu we-radial radial:Idizayini yokuxhumana yomugqa ibenza bakwazi ukuphatha imithwalo ephakeme kakhulu ye-radial kunamabhande ebhola elifanayo.
- Ubulukhuni obuphezulu obukhulu:Ukuqina okuhle kakhulu ekuqondeni kwe-radial, okuholela ekuguqukeni okuncane ngaphansi komthwalo.
- Ukuxabana okuphansi:Ukumelana okuphansi okuphansi kunomthelela ekusebenzeni kahle.
- Amandla aphezulu aphezulu:Ibhethri elakhiwe kahle (ikakhulukazi ngamakheji angasindi) alungele isivinini esiphakeme sokujikeleza.
- Ukuhlukaniswa:Izinhlobo eziningi (isb.
- Umthamo we-Axial Load Umkhawulo:Ngokuvamile kungahlalisa kuphela imithwalo emincane ye-axial (kuya nge-Rib Design), noma kudinge inhlanganisela namanye ama-bearings okusingatha amabutho angenzi.
Izicelo ze-cylindrical roller bear
I-Cylindrical Roller bearnings isetshenziswa kabanzi kuzinhlelo zokusebenza ezifuna umthamo omkhulu we-radial nokuqina:
- Ama-motor kagesi nama-generator:Ukuxhaswa kwe-rotor.
- Ama-gearbox kanye nama-reducers:Ukusekelwa kwe-gear shaft.
- Ukugoqa amagaya:Umsebenzi wokuqalisa kanye ne-backup roll chocks.
- Amaphampu kanye nama-compressors:Ukwesekwa kwe-shaft.
- Izikrini ezinyakazisa:Ukuphatha imithwalo ekhanyayo.
- Imishini yokwakha:Izindandatho ezibulewe ezibunjiwe kwabavubukuli, eCranes.
- Umoya womoya:Imigwaqo emikhulu shaft.
- Izikhonkwane zamathuluzi womshini:Lapho ubulukhuni obukhulu nokunemba kubalulekile khona.
- Imishini yokuphrinta:Ukuxhaswa kwe-cylinder.
I-Premium-Qualind Roller Bearrings iqinisekisa ukuthembeka okubucayi komsebenzi lapho umthamo wokulayisha we-radial engaxoxiswana khona.
