The broidered and dentated cordon of the eight and twenty royal niches; the immense central rose window, flanked by its two lateral windows, like a priest by his deacon and subdeacon; the frail and lofty gallery of trefoil arcades, which supports a heavy platform above its fine, slender columns; and lastly, the two black and massive towers with their slate penthouses, harmonious parts of a magnificent whole, superposed in five gigantic stories;--develop themselves before the eye, in a mass and without confusion,with their innumerable details of statuary, carving, and sculpture, joined powerfully to the tranquil grandeur of the whole

Firstly, the developing principles of the cylindrical internal helical gear are proposed through analyzing the movement and geometry requirements, which provides continuous contact between the mating gear surfaces. The tooth surface of the internal helical gear in the new gearing can be imagined as being generated by the normal section of the conjugated surface of the ball-tooth, moving along the radial projection of helix line of the tooth-root circle. Also, the proposed surface can be approximate tangent to the conjugated surface of the ball-tooth along a spacial curve.
