Abstract

Die Erfindung bezieht sich auf ein Schwingsystem für eine mechanische Uhr mit einer ringförmigen Unruh (1), die koaxial zu einer drehbar gelagerten Unruhwelle fest angeordnet ist. Eine Spiralfeder (3) umschließt die Unruhwelle und ist mit ihrem inneren Ende an der Unruhwelle und mit ihrem äußeren Ende an einer Befestigungsvorrichtung befestigt. Die Befestigungsvorrichtung weist eine Spiralklemme (16) mit einer zur Drehachse (2) der Unruhwelle radial inneren Spannbacke (17) und einer radial äußeren Spannbacke (20) auf, wobei das äußere Ende (19) der Spiralfeder (3) zwischen einer Spannfläche (18) der inneren Spannbacke (17) und einer Spannfläche (21) der äußeren Spannbacke (20) fest einklemmbar ist.

The invention relates to a vibration system for a mechanical clock with an annular balance (1) which is fixed coaxially to a rotatably mounted balance shaft. A spiral spring (3) surrounds the balance shaft and is attached with its inner end to the balance shaft and with its outer end to a fastening device. The fastening device has a spiral clamp (16) with a radially inner clamping jaw (17) and a radially outer clamping jaw (20) to the rotation axis (2) of the balance shaft, the outer end (19) of the spiral spring (3) between a clamping surface (18 ) of the inner clamping jaw (17) and a clamping surface (21) of the outer clamping jaw (20) is firmly clamped.
