Abstract:
The following specification describes a rotor and case in a gyroscopic device generally forming a ball-shaped apparatus having an internal circular race. The internal circular race supports the rotor, which is mounted on a shaft that extends through the rotor and is received in an opening of a T-shaped cross sectioned ring which is placed within the race. The rotor rotates through the spin axis thereof, while at the same time a second axis at right angles that intercepts the spin axis is established around which the rotor will precess. By giving the rotor an initial spin and then holding the support structure or ball in the hand and manually applying a torque to the support structure or ball, the rotor will precess about the second axis of precession and produce a torque opposing the manually applied torque. The rotor is provided with fins for maintaining the rotor in a smooth moving configuration, while at the same time cooling the spinning rotor so as to eliminate frictional wear. In addition thereto, a mass is placed in circumferential relationship around the spin axis to increase the momentum of the rotor during its spinning movement.
