Study on Deflection of Spur Gear Teeth : 2nd Report, Calculation of Tooth Deflection for Spur Gears with Various Tooth Profiles

Yoshio Terauchi, Kazuteru Nagamura

Abstract

二次元弾性理論と写像関数を用いて平歯車の種々の歯形に対する歯のたわみ計算を行い,これらの計算結果よりいずれの歯形にも適用できる平歯車のたわみ計算簡易式を作成した.また,本方法により求められたヘルツ接触による変形量 Weber, Lundberg の式による値と比較し,これらの式を歯車に適用する際に生じる問題点を指摘した.さらに本計算結果に基づいてヘルツ接触による変形量評価の近似式を導き,これを示した.
