High-rotational-inertia flywheel with guiding and positioning structure

The invention discloses a high-rotational-inertia flywheel with a guiding and positioning structure, and relates to the technical field of mechanical manufacturing of active pump flywheels, the high-rotational-inertia flywheel comprises a flywheel frame and a plurality of metal columns arranged in the flywheel frame, the cross section of each metal column is in a cam shape, and the protruding parts of the metal columns all face the axis of the flywheel frame; the multiple metal columns are arranged in the circumferential direction of the flywheel frame and are symmetrical about the axis of the flywheel frame. The flywheel frame is provided with a plurality of guide grooves matched with the metal columns, and the metal columns are embedded into the guide grooves. The bottoms of the connecting positions of the guide grooves and the metal columns are arc transition sections. An end cover is arranged at the top of the flywheel frame; by the adoption of the scheme, the requirements for reducing the size and improv
