  • Patent number: 3988045
    Abstract: An impact absorbing for an idler assembly is formed from a series of molded discs of synthetic material such as polyurethane or the like having a thickened hub with a non-circular central aperture that extends axially through the disc and permits the disc to be press-fitted onto a tube shell whose exterior configuration assumes a similar non-circular form. The dimensions of the central aperture in each disc are slightly less than the corresponding axial dimensions of the tube shell, so that the inherent resilence of each disc holds same securely upon the shell in a slip-free relationship; the preferred, commercially readily available non-circular shape is a a rectangle.The hub on each disc contacts the hub on the adjacent disc, so that the discs are retained in alignment with one another and tend to rotate as a unit. A metal reinforcing ring may be molded within the disc, if needed, to enhance its structural rigidity and further increase its ability to absorb impact forces.
