| Abstract: Technologies pertaining to a rotary electrical contact device are
described herein. A rotary electrical contact device comprises a first
sheave that is disposed about a first axis and a second sheave that
rotates about the first axis or a second axis that is parallel to the
first axis. The device further includes two planetary sheaves that
revolve around the first and second sheaves, and a belt that makes
contact with each of the sheaves, the belt comprising a co-wound inner
helical coil and outer helical coil. As the first sheave rotates, the
planetary sheaves revolve about the first and second sheaves and cause
the belt to deform and roll along the second sheave. The belt makes
rolling contact with the four sheaves. The belt is electrically
conductive such that as the belt rolls along the sheaves, the belt
maintains electrical contact between the first sheave and the second
sheave. |
