Abstract
A coupling system is disclosed for coupling rotating elements such as a pairs of shafts, flywheel and a shaft, and so forth. A first hub assembly is attached to a shaft via a tapered sleeve mechanism. A flexible element is captured by the hub assembly and is used to couple one rotating member to another. The hub assembly includes a hub, a flange, and an adjusting nut that are used in conjunction with fasteners to compress the flexible element. The flange has anti-rotation features that engage similar features on the outside diameter of the hub. The adjusting nut has internal threads that engage external threads on the hub outside diameter. The flexible element either mounts directly to the second rotating element or is captured by a second hub assembly. The second hub assembly is attached to the second shaft via a tapered sleeve mechanism.
