Abstract

A radially soft drive coupling for reducing vibration transmitted across the coupling in certain marine drive applications. The elastomeric elements interconnecting the hub and housing are precompressed by an amount which is at least in the range of 15-20% to produce significant radial and torsional softening of the spring rate of the elastomer. The radial spring rate whose magnitude expressed in lb/in is in the range of between one half and three times the magnitude of said design torque level expressed in lb-in.
