PDFAbstract: The investigation of the contact conditions, the effect of errors on them, as well as the optimization of the gears face difficulties because the contact lines continuously move and change their shape during gearing This paper presents a numerical method to determine the contact ratio of cylindrical worm gearing with modified profile. Both profiles, of worm and gear, are obtained numerically by the discreting of helicoidal surface with constant pitch.
Keywords: worm gearing, meshing, contact ratio, path of contact, contact points, gear flank profile
