ABSTRACT:
A tubular, resilient engine mount oriented parallel to the rotating power input or output shaft of a power producing or absorbing device. The novel mount yields to, and neither suppresses nor substantially transmits, torsional forces, relying on the self-equilibrating dynamics of the device to return to its original position. The tube attaches at one end to a disc or similar structure which will be fixed to the power device, and at the other end to a disc which will be fixed to the chassis supporting the power device. Axial and shearing forces are resiliently accommodated, and accommodation thereof may be augmented by rigid or resilient solid members located inside or outside the tube. The mount may be provided on only one side of the power device, or both fore and aft. In one alternative embodiment, the discs have a central bore, so that a rotating power shaft may extend through the mount. Provided by a section of pneumatic inner tube, a mount having a diameter of five and one half inches and length of two inches has successfully supported a five pound, two stroke engine operating at 9000 revolutions per minute for over one hundred total hours, without requiring repairs which were needed after only one hour when the engine was conventionally mounted.
