ABSTRACT:
A shaft arrangement (34) having a transversely displaceable weight member (42) relative to the shaft arrangement's longitudinal axis (B). The shaft arrangement (34) includes a housing structure (36) within compression structure (44) is arranged. The compression structure (44) extends through the housing structure (36) and connects to the displaceable weight member (42). An elastomeric member (50) is captured between the compression structure (44) and the housing structure (36) so as to resist transverse displacement of the weight member and the connected compression structure (44). The elastomeric member (50) maintains the weight member (42) and connected compression structure (44) in a rotatably balanced position relative to the longitudinal axis (B) for rotation speeds less than a predetermined amount. When the shaft arrangement (34) is rotated faster than such predetermined speed, the weight member (42) and connected compression structure (44) are transversely displaced so as to induce vibration in the shaft arrangement (34).
