Gravity rotation device

A gravity rotary device comprising:

• a first disk comprising:
• a central axis about which the first disk is capable of turning;
• and
• at least one peripheral axis of rotation arranged at a distance from and parallel to the central axis;
• at least one peripheral rotary shaft arranged at a distance from the central axis of the first disk, and suitable for turning about the peripheral axis of rotation, parallel to the central axis, and coupled to the first disk;
• and
• at least one mass support mounted on the peripheral rotary shaft and having a mass suitable for being moved away from the rotary shaft in order to produce torque causing the rotary shaft and consequently the first disk to pivot;
• a reduction gearing for reduction from the first disk to the mass support, the gearing being arranged between the peripheral rotary shaft and the first disk, the gearing comprising a rotary inlet part connected to the peripheral rotary shaft and a rotary outlet part connected to the first disk, the rotary inlet and outlet parts being on the same axis, the reduction gearing enabling the rotation of the peripheral rotary shaft to be transmitted to the first disk;
• means for fastening at least a portion of the reduction gearing in a stationary position in order to prevent it from turning about the peripheral axis of rotation;
• a freewheel arranged on the peripheral rotary shaft;
• and
• means for modifying the angle of inclination of a mass support on the peripheral rotary shaft relative to the horizontal passing through the peripheral axis of rotation of the shaft;
• wherein the means for modifying the angle comprises:
• at least one external cam arranged facing the outer end of a mass support and including a guide surface;
• a follower wheel arranged on an outer surface of a mass support and suitable for coming into contact with the guide surface of the cam during rotation of the first disk in order to guide the rotation of the mass support in the direction opposite to the direction of rotation of the first disk, by virtue of the freewheel and in order to change the angle of inclination of the mass support;
• a motor connected to the external cam and suitable for driving the cam in rotation about an axis of rotation of the cam in the same direction as the direction of rotation of the first disk;
• and
• means for resetting the device.

A method of assembling a gravity rotation device, the method comprising the steps of:

• mounting a first disk comprising:
• a central axis about which the first disk is capable of turning;
• and
• at least one peripheral axis of rotation arranged at a distance from and parallel to the central axis;
• mounting at least one peripheral rotary shaft arranged at a distance from the central axis of the first disk, and suitable for turning about the peripheral axis of rotation, parallel to the central axis, and coupled to the first disk;
• mounting a motor on the peripheral rotary shaft, to cause the peripheral rotary shaft to rotate about the peripheral axis of rotation;
• mounting a reduction gearing for reduction from the first disk to the mass support, the gearing being mounted between the peripheral rotary shaft and the first disk, the reduction gearing comprising a rotary inlet part connected to the peripheral rotary shaft and a rotary outlet part connected to the first disk, the rotary inlet and outlet parts being on the same axis, the reduction gearing enabling the rotation of the peripheral rotary shaft to be transmitted to the first disk;
• mounting a means for fastening at least a portion of the reduction gearing in a stationary position in order to prevent the reduction gearing from turning about the peripheral axis of rotation;
• mounting a freewheel on the peripheral rotary shaft;
• mounting at least one mass support on the peripheral rotary shaft, the mass support having a mass suitable for being moved away from the rotary shaft in order to produce torque causing the rotary shaft to pivot;
• and
• mounting a means for modifying the angle of inclination of the mass support on the peripheral rotary shaft relative to the horizontal passing through the peripheral axis of rotation of the shaft;
• and
• mounting a means for resetting the device.
• wherein the means for modifying the angle comprises:
• at least one external cam arranged facing the outer end of a mass support and including a guide surface;
• a follower wheel arranged on an outer surface of a mass support and suitable for coming into contact with the guide surface of the cam during rotation of the first disk in order to guide the rotation of the mass support in the direction opposite to the direction of rotation of the first disk, by virtue of the freewheel and in order to change the angle of inclination of the mass support;
• and
• a motor connected to the external cam and suitable for driving the cam in rotation about an axis of rotation of the cam in the same direction as the direction of rotation of the first disk.
