One of the most important performances which a pair of tooth surfaces of gears for power transmission must have is smooth and quiet transmission of the torque. However, the present designing methods of gears cannot choose the tooth surfaces to satisfy the performances, because they have no designing criteria in choosing the tooth surfaces from the view point of the dynamic requirements like "no variation of bearing loads". Therefore, according to the present methods, any pair of conjugate surfaces has no difference as that of gears for power transmission so that the easiness of production is the only criterion in choosing the tooth surfaces. In this series of papers, a unified designing method for all kinds of gears is presented, in which the designing conditions of gears for power transmission are clarified and the tooth surfaces are determined directly by them in the unified coordinate systems which are determined by the disposition of two axes and the axis of relative rotation. The first paper discusses basic characteristics of a path of contact, such as, its surface of action and tooth surfaces in the vicinity of a point of contact, radii of curvature, limits of action and velocities (pheripheral, normal and relative) which are basic parameters necessary to design tooth surfaces, when the equations of a path of contact and its contact normals are given in the unified coordinate systems.
