Abstract
The flywheel device comprises a disc-shaped body, a pair of ball screw members, and a pair of masses. The ball screw member includes a screw shaft and a pair of ball nuts. The screw shaft is received in the disc-shaped body and has a middle section, a left section with forward threads, and a right section with reverse threads. One of the ball nuts is screwed to the left section of the screw shaft, and the other ball nut is screwed to the right section of the screw shaft. One of the masses is coupled to the ball nuts screwed to the left sections of the screw shafts, and the other mass is coupled to the ball nuts screwed to the right sections of the screw shafts.
Claims9
A flywheel device, comprising:
- a disc-shaped body to be coupled to an external driving source;
- a pair of ball screw members;
- a pair of masses;
- each of the ball screw members including a screw shaft and a pair of ball nuts;
- the screw shaft radially pivoted within the disc-shaped body and having a middle section, a left section having forward threads, and a right section having reverse threads,
- one of the ball nuts screwed to the left section and the other ball nut screwed to the right section to allow each of the ball nuts moving back and forth between a starting position and an ending position;
- and
- one of the masses being coupled to the ball nuts screwed to the left sections of the screw shafts and the other mass being coupled to the ball nuts screwed to the right sections of the screw shafts to allow the masses approaching or moving away from the middle section synchronously, thereby enabling the moment of inertia of the flywheel to be variable.
