Abstract: An intersection between a first circular arc traced around a given measuring point on a toroidal surface on one side by the extreme end of a segment with a length equal to the curvature radius of traction surfaces of discs and a second circular arc traced around a given measuring point on a toroidal surface on the other side by the extreme end of the segment is obtained in a cross section along the central axis of the power roller. A plurality of intersections are obtained by repeating the process for obtaining the intersection for each of different measuring points on the toroidal surfaces. That specific one of the intersections which is situated nearest to the reference surface of the power roller is selected and it is concluded that the selected intersection is the tilting center of the discs.
