概要

論文の詳細を見る
In the first report, the method of generating Concave conical gears was presented. In this paper, first the principal normal radii of the tooth surface generated by this method are expressed theoretically in terms of the basic dimensions of the gear and the tool. The principal normal radii of test gears are measured and found to be in good agreement with the theoretical values. Secondly, the allowable normal load of a pair of Concave conical gears is obtained. Tooth bearing tests prove that the Hertzian contact ellipse is larger than that of the conventional conical gear. Thus it is proven that the method of designing a pair of Concave conical gears is of practical use.
