• 論文の詳細を見る

• The purpose of the present paper is to examine the influence of centrifugal force on stresses at each position of a force-fitted gear under running condition, and to discuss on safe designing of a force-fitted gear when the influence of centrifugal force is considered. The following conclusions are obtained. (1) The stress caused by centrifugal force becomes maximum at the position where the center line of tooth space crosses the root circle, and the stresses at each position of gear and the decrease of interference at force-fitted surface are proportional to square of number of revolutions. (2) A practical formula to decide the maximum stress, the fillet stress at the position where Hofer's weakest section crosses the trocoid curve at the root fillet of tooth and the decrease of interference can be introduced.
