A gyroscopic rotor has a shaft with opposite ends rotatably supported in a housing on a first or spin axis and capable of rotating around the housing at right angles to the spin axis, comprising a second axis. The support of the shaft in the housing is a circular track concentric with the second axis and positioned on opposite sides of and adjacent the ends of the shaft for rolling contact by end portions of the shaft when a torque is applied to the housing about a third axis at right angles to ...
