The shaft coupling has a pair of parallel sheetmetal membranes which are fixed together at their outer periphery and at their inner peripheries and are connected by respective sets of connectors to a hub and a formation which can be connected to another shaft. The connectors can include clamping bushes which have their heads or shoulders between the membrane and are engaged by clamping screws extending into the bushes from the exterior so that between the membranes, only the thickness of a shoulder is provided along the inner periphery. A highly compact shaft coupling can be obtained in terms of axial dimensions.

A shaft coupling for compensating radial, axial and angular relative movements between a pair of shafts extending generally along an axis, the coupling comprising: a first member connectable to and rotatable about the axis with one of the shafts and a second member connectable to and rotatable about the axis with the other shaft with relative radial, axial and angular movement between said shafts; at least one tandem-membrane assembly forming an elastically bendable connection between said members, said tandem-membrane assembly comprising: two substantially parallel annular membranes lying generally transverse to the axis of the shaft coupling and having respective inner peripheries each formed with an annular array of holes, respective outer peripheries, inner faces directed toward each other and outer faces directed away from each other, and means for fixedly connecting the outer peripheries of said membranes together; and respective connecting means for operatively connecting each of said inner peripheries to a respective one of said members, at least one of said connecting means including: an annular clamping formation engaging the outer face of one of said membranes and connected to the respective member and provided with bores axially aligned with the holes in said one of said membranes along said inner periphery thereof, respective clamping screws traversing said bores and the respective holes, and respective internally threaded clamping bushes directly threadedly engaged by said screws, each of said clamping bushes having a sleeve portion extending through the respective hole into a respective bore of said clamping formation and formed with an internal screwthread, and a respective shoulder formed on an end of the respective sleeve portion turned toward the other of said membranes and directly engaging against the inner face of said one of said membranes for clamping said one of said membranes between said shoulder and said formation; respective clamping screws connecting said other of said membranes to the other of said members, the screws of each of said membranes being angularly spaced around respective pitch circles of different radii.
