Recently, the reduction of cost in the gear field has become a serious problem and consequently, the force-fitted gear has become the subject of attention. Although some studies on force-fitted spur gears have been presented, there have been very few studies hitherto which deal with force-fitted helical gears. In view of such a situation, the force-fitted helical gear was chosen as the subject of the author's study. That is to say, by using the three-dimensional finite element method, stresses at the root fillet of a gear tooth caused by force-fitting were calculated. Practical formulas of these stresses can be introduced.
