Abstract
A torsionally flexible coupling comprises an inner part having a rotating shaft, an outer part extending around the inner part and arranged coaxially thereto, and spring elements or spring packs arranged between the inner part and the outer part and spaced in circumferential direction, wherein each spring element or spring pack is clamped at a radially outer end in a clamping support on the outer part, and a radially inner end is flexibly engaged with a corresponding groove on the inner part. In position of rest the spring elements or spring packs are angled relative to a radial direction passing through the respective clamping support and are inclined against the main direction of rotation of the coupling. Such an inclined position of the spring elements or spring packs allows a reduction of the portion of damping caused by friction so that damping can become predominantly hydraulic.
