Abstract
Herein disclosed is a torsionally resilient shaft coupling for serially transmitting torque and to provide a substantial amount of torsional flexibility between a pair of axially spaced coaxially aligned shafts. The torsionally resilient shaft coupling comprises a first inner sleeve and a second inner sleeve coaxially aligned with and axially spaced from the first inner sleeve. A first outer sleeve is connected to a first of the shafts and surrounds the first inner sleeve forming a first annular space therebetween. A second outer sleeve is connected to a second of the shafts and surrounds the second inner sleeve forming a second annular space therebetween. At least one first annular torsionally resilient member is interposed in the first annular space and is connected to the first inner sleeve and to the first outer sleeve to provide primary torsional flexibility between the first outer sleeve and the first inner sleeve. At least one second annular torsionally resilient member is interposed in the second annular space and is connected to the first inner sleeve and to the second outer sleeve to provide secondary torsional flexibility between the second outer sleeve and the second in…
