| 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 having an aspect ratio great
than 1:1. 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 comprises electrically conductive components arranged
such that as the belt rolls along the sheaves, the belt maintains
electrical contact between the first sheave and the second sheave. |
