Abstract: Two opposed bosses each possessing an outwardly open bore for engagement to a shaft end are bonded to either end of a single layer annularly convoluted, bellows style, hollow cylinder shielded by an exteriorly disposed cylindrical rubber sleeve. Torsional rigidity and longitudinal flexibility in torque transfer is provided by the bellows style medial member. The rubber sleeve provides vibration dampening which increases operational velocity and, more significantly, operational life by reducing vibration duration of resonant frequency by an average of fivefold with a cold fitted rubber sleeve, and tenfold with a hot fitting, about the bellows. Hot fitting melts the rubber sleeve and fills the exterior annular grooves of the bellows without the expense of molding under pressure and results in an increase of the resonant frequency and corresponding rotational speed of nearly threefold. Brass is suggested for the opposed bosses and phosphorus bronze for the bellows. Chloroprene rubber is suggested for the sleeve.
