Torsionally flexible coupling

摘要

A torsionally flexible coupling (10) comprises an inner part (11) having a rotating shaft (A), an outer part (12) extending around the inner part and arranged coaxially thereto, and a plurality of spring elements (16) or spring packs which are 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 (17) in a clamping support (18) on the outer part, and at a radially inner end (20) is flexibly engaged with a corresponding groove (21) on the inner part. In position of rest of the torsionally flexible coupling 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.
