Abstract

A shaft vibration absorber for absorbing vibrations of a shaft includes an elastomer body that is reached through by a central longitudinal centre axis. In embodiments, the elastomer body includes holding geometries that protrude in the radial direction and extend in the longitudinal direction for pressing the shaft vibration absorber to the shaft. The holding geometries may be arranged in each case in two first angle windows that lie opposite one another with regard to the longitudinal centre axis with a width of in each case at most 90°. With embodiments, the shaft vibration absorber can configure a radial pressing force of the shaft along a first tuning axis that runs in the radial direction, and the radial pressing force may be greater than a pressing force in a spatial direction that differs therefrom and runs in the radial direction.
