Answer
Nkuko isoko yumuraba ifunitse, hagati ya diameter $ D_m $ yaguka. Kwiyongera kwa theoretical $ \ Delta D $ birashobora kugereranywa nka $ \ Delta D = \ frac {0.05 f ^ 2} {D_m Z ^ 2} $, aho $ f $ aribwo gutandukana. Niba itandukanyirizo riri hagati ya Diameter yo hanze ($ OD $) hamwe nuburaro bwamazu bidahagije, isoko izahuza, biganisha ku gipimo cyimvura idahwitse kandi gishobora guhurira hamwe. Kubisanzwe bisanzwe byimbere, diameter ya bore igomba kuba byibuze $ 102-105 \% $ yubusa $ OD $. Muri ubwo buryo ,, kubisabwa hanze hejuru yumutwe, diameter ya shaft igomba kuba hafi $ 95-98 \% $ yubusa $ ID $ $ kubuntu. Ibi bisobanuro kandi bitanga ingano ikenewe kumavuta yo kwisiga mumateraniro yihuta yihuta nkamapaki.
