Abstract
A flywheel having a hollow rotatable structure which is driven for rotation on a predetermined axis and presents a cam surface eccentrically surrounding that axis, a guide arrangement inside the rotatable structure presenting a plurality of slideways extending outward from that axis to the cam surface, and rollers slidable along those slideways and engageable with the cam surface. The rotatable structure is rotatable with respect to the guide arrangement. The rollers provide the only coupling between the rotatable structure and the guide arrangement.
Claims10
A flywheel comprising:
- a rotatable structure having a predetermined axis of rotation, said rotatable structure including cam means having an annular cam surface extending eccentrically around said axis;
- means for driving said rotatable structure for rotation on said axis;
- guide means inside said rotatable structure presenting a plurality of slideways which extend out from said axis;
- and a plurality of rollers operatively coupled to said guide means to slide along said slideways, said rollers being engageable with said cam surface to be displaced toward and away from said axis during the rotation of said rotatable structure;
- said guide means being rotatably mounted with respect to said rotatable structure at the inside of said rotatable structure and being coupled to said rotatable structure only through said rollers.
