Abstract
An elastically deformable transmission member for use in a friction drive system. The elastically deformable transmission member imparts a thrust to a moveable member at an area of contact between the elastically deformable transmission member and the moveable member. Elastic deformation of the elastically deformable transmission member, such as by application of a pre-load force perpendicular to the direction of motion of the moveable member, causes an increase in contact area between the elastically deformable transmission member and the moveable member. The increased contact area reduces stress in the elastically deformable transmission member and the moveable member, reducing wear.
