Abstract
A drive assembly couples a driving mechanism, e.g., an engine, and a driven mechanism, e.g., a generator, to one another. The assembly includes a transmission member having a plurality of inwardly projecting fingers and a coupling having a plurality of outwardly directed projections interdigitated with the fingers. The projections include first and second projections which define a notch between them. A finger extends into the notch, thereby forming first and second pockets between the finger and the first and second projections, respectively. In the improvement, the first and second resilient devices are received in the first and second pockets, respectively. Each resilient device includes at least one spur projecting from it to prevent substantial rotation of the device in its pocket. In a more specific embodiment, alternating pairs of resilient devices are made, respectively, of natural rubber for good shock absorption and Buna N for resisting the harmful effects of oil.
