30202 ama-roller bearings, umugqa owodwa

Incazelo emfushane:

Ama-roller bearings ane-tapered yomugqa owodwa aklanyelwe ukuthwala imithwalo ehlanganisiwe, ngesikhathi esisodwa esebenza imithwalo ye-radial ne-axial. Imigqa yokuqagela yemigwaqo yomjaho ihlangana endaweni efanayo ku-eksisi ethwalayo ukuze inikeze isenzo sokugingqika sangempela kanye nezikhathi zokungqubuzana eziphansi phakathi nokusebenza. Umthamo wokuthwala umthwalo we-axial wamabheringi acijile uyakhula ngokukhula kwe-engeli yokuxhumana u-α. Usayizi we-engeli yokuxhumana, ngokuvamile ephakathi kuka-10° no-30°.

Izici ze-Tapered roller bearings

1.Ukungqubuzana okuphansi
Idizayini yokuphela kwerola ethuthukisiwe kanye nokuqedwa kwengaphezulu ku-flange kukhuthaza ukwakheka kwefilimu ye-lubricant, okuholela ekungqubuzaneni okuphansi. Lokhu futhi kunciphisa ukushisa okungqubuzanayo nokugqoka kwe-flange.

2.Ukuthembeka kokusebenza okuthuthukisiwe
Ukuqedwa kwendawo okulungiselelwe ezindaweni ezithintana nama-roller nezindlela zomjaho kusekela ukwakheka kwefilimu ye-hydrodynamic lubricant.

3.Ukuvumelana kwamaphrofayili namasayizi we-roller
Ukubekezelelwa kwe-dimensional kanye ne-geometrical kwama-roller ama-tapered kuyefana. Lokhu kunikeza ukusabalalisa komthwalo okulungile, kunciphisa umsindo nokudlidliza, futhi kunika amandla ukulayisha kuqala ukuthi kusethwe ngokunembe kakhudlwana.

4.Rigid esinesicelo
Irowu eyodwa ene-tapered roller bearing ivamise ukulungiswa ngokumelene ne-roller tapered yesibili. Ngokusebenzisa ukulayisha kuqala, uhlelo lokusebenza oluqinile lungafinyelelwa.

5.Ahlukene
Indandatho yangaphakathi ene-roller ne-cage assembly (cone) ingafakwa ngokuhlukana nendandatho yangaphandle (indebe).
