Answer
Igice cyagumishijwe (igice gifashwe mu mwanya) akenshi gifite chamfer cyangwa radiyo kuruhande rwacyo kugirango byoroshye gukora. Nyamara, iyi chamfer ikora 'ramp' ikoresha radiyo yingufu $ F_r = F_a \ tan (θ) $ kumpeta igumana, aho $ F_a $ nimbaraga za axial naho $ heta $ ni inguni. Izi mbaraga za radiyo zikunda gusunika impeta hanze. Niba chamfer ari nini cyane, irashobora gutuma impeta 'isahani' ikananirwa imburagihe. Umubare ntarengwa wemewe cyangwa radiyo ku gice cyagumishijwe usanzwe ugaragara mu mpapuro zerekana amakuru ya tekiniki (urugero: $ r_ {max} <0.5 \ cdot d $, aho $ d $ ari ubujyakuzimu). Niba icyuma kinini kidashobora kwirindwa, hagomba gukoreshwa 'kwaduka-impande zombi' kumanura ibikoresho kugira ngo umutwaro ushyirwe mu buryo bwuzuye mu maso.
