Abstract
A torsional coupling includes a body having a circumference and defining a center axis. The body is rotatable about the center axis. The coupling also includes a ring including an inner diameter disposed about the circumference. The ring includes a ring contact surface having a first radius and the ring is configured to rotate about the center axis. A coupling element is associated with the body and is configured to apply a centrifugal force radially outwardly from the circumference of the body when the body rotates. The coupling element includes a coupling element contact surface having a second radius which is different than the first radius of the ring contact surface. The coupling element contact surface is in contact with the ring contact surface and is configured to apply a force against the ring contact surface to rotate the ring relative to the body and increase the effective stiffness of the torsional coupling as the rotational speed of the body increases.
