DAMPER FINGER SEGMENT

摘要

A damper finger segment is radially disposed between a retaining ring and a damper ring arrangement at a rotor end of a generator arrangement, in particular of a high power turbogenerator, having a multitude of plate-like finger elements with a longitudinal extension and arranged parallel to each other. Each neighboring pair of finger elements encloses a gap and all finger elements are joined at one end of each finger element by a band-like strip section having a longitudinal extension being oriented orthogonally to the longitudinal extension of the finger elements. At least one slot is provided in each plate-like finger element and/or in the band-like strip section. The at least one slot has a slot axis oriented parallel to the longitudinal extension of the plate-like finger elements.
