Abstract
The torsional connection has two hubs attached to the input and output shafts and an intermediate member coaxially located between the hubs. Each hub is connected with the intermediate member by two diametrically disposed pairs of laminates composed of bonded together thin alternating layers of elastomeric (rubber--like) and rigid (e.g., metal) materials. Each pair is preloaded in compression. Diameters of the intermediate member along which the pairs of laminates connecting it with each hub are located, are perpendicular to each other. Torque transmitted through the connection is loading the laminates in compression, while radial misalignments between the connected shafts are compensated by shear deformations of the laminates. The laminated elements of each pair are located on opposite sides of a two-pronged holding structure whose prongs are expanded outwardly by a preload-generating element inside the holding structure. The same preload-generating elements tie the holding structure into a rigid frame for transmitting tangential force in the torsional connection.
