Abstract
The device for mechanically transmitting torque from a motor to a power transmission is especially suitable for marine propulsion systems as a sound-damping transfer coupling of a drive shaft. The device comprises a damping member with two halves mirror-symmetrical relative to a plane that is perpendicular to the axial direction. Each half is a composite body comprised of a first and a second conical rubber ring of opposite conical orientation. The second conical rubber ring is concentrically arranged inside the first conical rubber ring. A metallic conical center ring is vulcanized to the mantle surfaces of the first and second conical rubber rings that are facing one another. A metallic outer ring is vulcanized to an outer conical mantle surface of the first conical rubber ring and a metallic inner ring is vulcanized to an inner conical mantle surface of the second conical rubber ring. The device further comprises screws for fastening the two halves to one another at the inner and outer rings, whereby the halves are arranged such that a respective base portion of the conical center rings face one another. The device has a strong center ring effect in all directions so that a universal joint may be guided and supported without any further mechanical bearings for the drive shaft.
