Annular disk for flexible shaft couplings, disk packet made from these annular disks, and flexible shaft coupling with such annular disks

摘要

An annular disk for flexible shaft couplings is described, whose two coupling halves each exhibiting a connection flange are connected to each other via a packet of such annular disks in a torsionally rigid manner, but in such a way as to enable their axial and angular movement. The annular disk has four attachment holes uniformly distributed on a shared hole circle, wherein the section is tapered between two adjacent attachment holes. The annular disk according to the invention 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 the diameter of the hole circle, D1 is the diameter of the respective attachment hole, D2 is the largest outside diameter of the annular disk, B1 is the width of the narrowest part of the annular disk section between two consecutive attachment holes, and B2 is the width of the annular disk outer contour. The annular disk according to the invention makes it possible to offset relatively large dislocations.
