Title:
Rotary drive
Document Type and Number:
Japanese Patent JP6108488
Kind Code:
B2
Abstract:
A rotary driving apparatus is provided that is capable of rotating a rotary body by varying a weight balance, and to efficiently achieve the rotation of the rotary body while generating little noise such as collision noise. A rotary driving apparatus 1 includes a rotary body 5 having a point O as its center and rotatable around the point O, rotation detecting means 6 for detecting its rotational state, six rotary weight devices 7a to 7f on the body 5, and a power generation device 8 generating electric power by the rotation of the body 5, wherein each of the devices 7a to 7f includes a rotary arm 10 rotatably mounted to the body 5, the arms 10 at approximately six-fold symmetrical positions about the point O, a motor 11 to rotate the arm 10 at a rotational speed same as the body 5 in a rotation direction opposite to a rotation direction of the body 5, and a weight 12 on the arm 10 on its free end side, and wherein all the devices 7a to 7f are controlled by the motors 11 such that all the arms 10 are oriented laterally on a same side, and the body 5 is rotated by a weight balance about the point O among all the weights 12 on all the arms 10.
