Abstract: A coupling between a driving and a driven shaft includes a rigid tube to which are attached by bonding, in axially spaced apart relation at least two flexible annular elements of elastomeric material, the annular elements being of various shapes; the outer periphery of each ring is bonded to an attachment ring which is attachable to a flange of a connecting hub with each hub mounted or connected to one the shafts; in one form the tube is split axially and is adjustably attachable to the periphery of the rings.

Abstract: An improved plate adapter for use with flexible couplings is disclosed which incorporates radially outwardly disposed pilot flanges for engagement with the hub and sleeve of the half coupling which pilot flanges are designed to form a pressfit relationship with the mating surfaces of the hub and sleeve. A suitable bolting arrangement is provided to aid in fitting of the adapter plate to the half coupling as well as to assist in removal of same. Additionally, the fastener arrangement enables fine adjustment of the radial runout of the sleeve of the half coupling relative to the axis of rotation of the shaft to which the half coupling is secured.

Abstract: A flexible coupling and torque monitoring device includes a hub having two sets of flexible spokes extending radially outwardly from a common hub to respective separate rims; the rims are each provided with fingers attached at one end to one rim and with the opposite end extending over the other rim with the fingers of one rim interspersed with the fingers of the other rim; the rims are each attachable respectively to the end of a drive and driven shaft; a sensing member is located radially outwardly of the rims to detect deviations in the spacing between the fingers.

Abstract: A torque measuring device utilizing composite and ferromagnetic materials includes an elongated shaft which is fixed at one end to a hollow or solid shaft with the other end being free of attachment to the shaft and including a plurality of circumferentially and evenly disposed signalling generator projections which are interleaved with similarly shaped projections mounted on a second member attached to the shaft so as to position the signal generating fingers in interspaced relationship about the circumference of the shaft body; at least two detecting sensors are located adjacent the projecting interspaced fingers in the same plane and spaced 180.degree. apart from each other to minimize or eliminate any inaccuracies in measuring the torque reflected in non-arcuate variations in the spacing between the fingers of one member relative to the other member.

Abstract: A flexible member for coupling a driving member to a driven member is an elastomer element formed with a plurality of integrally formed segments of tapering cross sectional area and is provided at the intersections of the segments with connecting elements for connecting the flexible member to the driving and driven members; the connecting element is formed in a manner that prevents rotation of the elastomer member relative to each point of connection; the segments of the flexible member are shaped in such a manner to maximize resistance to deformation under the influence of torque loading and misalignment.

Abstract: A flexible coupling element used in a flexible coupling for interfacing a drive shaft and a driven shaft and for transmitting torque therebetween while accommodating angular misalignment; the flexible coupling may be offset-link type or single disc type, both types incorporating a composite fiber wound around drive-bushings and driven-bushings in a winding pattern; the flexible coupling element being formed by compression and heat cured so that the runs connecting each bushing taper to a point midway between adjacent bushings.

Abstract: A coupling member comprises peripheral flanges and a body, with the peripheral flanges having the same axis of rotation. The body of the coupling member has a smoothly curving hub portion extending to two axially separated disk portions and is defined by three relationships. A thickness relationship describes the thickness of the body throughout the hub and disk portions. A spacing relationship describes how much of the body is to be occupied by the hub portion. A continuity relationship describes the thickness of the body within the hub portion.
