20100257974 | Mechanical machine designed to utilize unbalanced torque to enhance angular momentum - A uniquely designed mechanical mechanism integrated with an off set type flywheel that requires minimum energy input to enhance sustained maximum output. Revolving and oscillating spherical units, relevant to the machine's center of gravity, produces an unbalanced torque to the machine's rotor. The rotor will therefore rotate with minimal energy input and will sustain average angular velocity, independent of an external power source, for a longer period of time than a traditional flywheel of like mass. The unbalanced torque is produced by changing the positions of the spheres relevant to the machine's center of gravity. This is done by the use of a stationary power track, one-half shaped as a semicircle with the other half shaped as a parabola. In this stationary track, which is rigidly incorporated with the mounting bracket and the rotor's axel, there are installed yo-yo shaped casters that are connected to the spheres by use of connecting support rods. These connecting support rods pass through linear bearings which are housed in portals of the rotor's off-set. Due to the rotation of the rotor the connecting support rods force the yo-yo shaped casters to follow the power track thus creating a revolving and oscillating effect on the spherical units in reference to the machine's center of gravity. Keep in mind that the mass of the rotor is in perfect balance but the force exerted on it by the power stroke assembly unit cause it to experience unstable equilibrium thus sustaining rotation and angular momentum. | 10-14-2010 |

A hub ring main body of the hub ring pressure-contacts an inner periphery of the wheel ring while the flywheel is rotating. The pressure contact of the hub ring with the inner periphery of the wheel ring allows compressive stress applied to the wheel ring in a radial direction to cancel a portion of tensile stress acting in the wheel ring in the radial direction. As a result, the stress in the wheel ring in the radial direction decreases. | 03-03-2016 |
