Abstract:
A screw-locking device for attaching a first rotatable element to a second rotatable element that they may rotate together around a rotation axis, the screw-locking device comprising:an annular spring collar mountable on the first element in a rotationally locked manner, the annular spring collar comprising a radially inner ring, a radially outer ring outward of the inner ring and a toothed rim extending in the direction between the inner and outer rings; the toothed rim comprising a plurality of radial direction webs between the inner and outer rings and facing in a first axial direction, the webs being spaced apart in the circumferential direction around the spring collar and defining intermediate spaces between adjacent webs; a catch disk mountable on the second element in a rotationally locked manner, the catch disk having a second toothed rim including teeth projecting in a second axial direction toward the webs, and at least some of the teeth on the second toothed rim engaging the radial webs of the spring collar in order to avoid relative rotation of the first and second elements.
