A design method of a novel mechanism consisted of a double-cone and two circular rails eccentrically positioned, is proposed. On one hand, this mechanism can be regarded as a gravitational motor that transforms the potential energy into kinetic energy, of rotation and translation. On the other hand, it can be regarded as a mechanism, able to transform the kinetic energy of translation into kinetic energy of rotation. Several applications can be envisaged for this kind of mechanism, but it seems to be appropriate for electrical power generation from the energy of ocean and sea waves. Concretely, in this work, movies of a double-cone made in S45C carbon steel, rolling on straight and circular rails made of aluminum alloy and placed on a horizontal table, were shot. Number of rotations, the variable period of rotation, and the total travelling time were determined through the slow motion processing of the movies. A geometrical model to describe the particular kinematics of the double-cone, and a contact model for such particular Hertzian contact problem, were proposed and validated by experimental results. Such models produce the foundation of the suggested design method for the double-cone mechanism, based on which, the optimal design of the associated gravitational motor and generator can be achieved.
