Abstract
【解決手段】円錐ころ3の平均直径DRAVEと内輪1の内径DIiとの比DRAVE/DIiを0.45〜0.70とすることにより、内輪1の内径DIiが9mm以下の極小サイズの円錐ころ軸受で高い動定格荷重を確保できるようにした。
【選択図】図1
Description
(DR+C)・N=π(DIO+DR) (1)
ここに、Cはころ間の周方向隙間、DIOは内輪軌道面の外径である。
したがって、図3(a)、(b)に示した動定格荷重Pcに対するころの直径DRおよび本数Nの関係と、(1)式で制約されるころの直径DRと本数Nの関係とから、ころ軸受の動定格荷重Pcは、(2)式で表すことができる。
Pc=a{π(DIO+DR)/(DR+C)}3/4・DR29/27 (2)
ここに、aは比例定数である。
Pc=a1{π(DIOAVE+DRAVE)/(DRAVE+C)}3/4・DRAVE 29/27 (3)
ここに、a1は比例定数である。
