Abstract:
An annular disk for flexible shaft couplings, whose two coupling halves, each having a connection flange, are connected to each other via a packet of said annular disks in a torsionally rigid manner, but in such a way as to enable their axial and angular movement, wherein the disk packet is alternatingly secured to both connection flanges via circumferentially distributed attachment and clamping means, and wherein said annular disk has four attachment holes uniformly distributed on a common hole circle, and the width of said annular disk tapers between two consecutive attachment holes, wherein the taper between two adjacent attachment holes is defined by a recess with a central, straight outer contour section and an inner contour section running parallel thereto, wherein said inner contour sections are continuously connected with each other via groove sections having a circular arc profile, while said straight outer contour sections pass over into outer contour sections also having a circular arc profile, and wherein said circular arc profiles have the same circular arc radius, characterized by the fact that the annular disk satisfies the following size ratios:Dt/D1=10 to 12, D2/Dt=1.1 to 1.2, Dt/B1=9 to 16, and B2/Dt=0.88 to 0.93, wherein Dt is a diameter of said hole circle, D1 is a diameter of the respective attachment hole, D2 is a largest outside diameter of said annular disk, B1 is a width of a narrowest part of said annular disk section between two consecutive attachment holes, and B2 is a width of said annular disk outer contour.
