Abstract
A flexible, rotating drive transmission assembly having a substantially spiral-shaped liner supporting a center, rotatable, flexible shaft. The liner and its center shaft are carried within an outer down-tube. The spiral-shaped liner contains flexible, continuously tapering, elliptical legs that are self-adjusting and allow the liner to be easily inserted into and firmly retained by the outer down-tube. The self-adjusting legs of the liner conform to the inside diameter of the outer down-tube despite internal variations, thus allowing the liner to maintain its central axis or centerline relative to the central axis of the outer down-tube and end components attached to the assembly. The legs provide vibration isolation and absorption by their inherent spring effect. Moreover, grease skived from the inner wall of the outer down-tube, due to the auger effect of the rotating flexible shaft, is uniformly collected in pockets for distribution along the entire length of the outer down-tube.
