Abstract
Description
前記軸受の外輪は、以下の式(1)で求められる弾性度を有しており、
弾性度(N/mm2)=E×I×(1/D4)・・・(1)
E:縦弾性係数,I:断面二次モーメント,D:外輪の外径
さらに、前記弾性度は、7.8×10-5~2.7×10-2である。本発明の波動歯車装置によれば、実用に耐え得る範囲内で動力伝達効率が向上する。
弾性度(N/mm2)=E×I×(1/D4)・・・(1)
E:縦弾性係数,I:断面二次モーメント,D:外輪6aの外径
ここで、外輪6aの外径Dは、軸受6を波動生成コア5に取り付ける前の、軸受6が真円状態であるときの、外輪6aの直径である。
厚さ率(%)=t/D・・・(2)
D:外輪6aの外径、t:外輪6aの厚さ
