Abstract
Abstract A coupling for two generally coaxially aligned shafts which comprises an annulus having a series of rectilinear, resilient, and compressible columns connected with their longitudinal axes along the sides of a flat polygon. Arms project transversely from the longitudinal axes at each intersection of two adjacent columns; the arms alternately project from the front and rear faces of each of the adjacent columns with respect to the plane of the flat polygon. Hubs are secured on each of the shafts for receiving the alternate arms on the annulus respectively; fasteners operate radially through each arm for securing the arms to the hubs and decreasing the radius of the annulus thereby placing the columns under a precompressive load. A recess is formed on each of the front and rear faces of each column extending from the projection of the arms toward the opposite end of each column for reducing axial thrust during compression of the annulus.
