Answer
Mugihe cyo kwikuramo, diameter yo hanze ($ OD $) yisoko yumuraba iraguka nkuko impinga yumuraba iringaniye. Umubare ntarengwa $ OD $ ku burebure bwuzuye ushobora kugereranywa na $ OD_ {max} = ext {Hagati ya Diameter} + ext Wall Urukuta rwa radiyo} + ext {Ikintu cyagutse} $. Amategeko ngengamikorere ni $ Clearance_ {min} = 0.02 imes ext {Gutandukana} imes ext {Umubare w imiraba} $. Niba imyubakire yimyubakire ifunze cyane, isoko izahambira kurukuta, bigatuma ubwiyongere butangaje kandi butagengwa nigipimo cyimpeshyi hamwe nubutaka bushobora gutemba. Ba injeniyeri bagomba kwerekana diameter ya bore nka Bore $> OD_ {max} + ext {Tolerance Stack-up} $.
