Abstract
A friction drive including a drive shaft that is in rotational motion and in frictional contact with a follower at a contact area. The drive shaft transfers a thrust at the contact area. The follower receives the thrust and provides motion in response to the thrust. A flexure hinge couples the drive shaft to the follower with a constant force while restraining movement of the contact area in the direction of the thrust.
