In this paper the three kinds of skew gear pairs having uniform expression of contact condition similar to that of spur gears are discussed. The three kinds of skew gear pairs are the gears (gears I ) having the tooth surface of involute helicoid group, and the gears (gears II) having the tooth surface of spherical involute group, and the gears (gears III) having a rotating tooth surface. The uniform expression is effective to clarifiy contact space image and contact characteristics of the skew gears, and to derive contact condition and solution of contact condition of the skew gears. First, tooth surface formation of the gears are discussed. Second, contact space image and contact characteristics of the skew gears are clarified. Third, contact condition and solution of contact condition are derived. This solution is very important in engineering and contributes to effective calculation of the zone of contact and the mating tooth surface. Finally, for examples, the solutions of contact condition of the skew gears are applied to the hourglass worm gears.
