Abstract
In a non-circular gear pair comprising two non-circular gears maintained engaged, those gears have first and second intermeshing rotation parts in such a manner that the first intermeshing rotation part forms an intermeshing pitch curve with which the speed of rotation is given to one of the two gears which changes exponentially with respect to the speed of rotation of the other non-circular gear, and the second intermeshing rotation part is extended between the start and en-d points of the first intermeshing rotation part so as to form an intermeshing pitch curve with which the rotation speed ratio and the angular acceleration ratio change continuously, whereby the rotation speed and the angular acceleration change continuously throughout the first and second intermeshing rotation parts including the connecting points thereof.
