ABSTRACT:
A torsional vibration balancer, especially for piston type apparatus having a secondary side seismic mass radially outside a primary member connected to a shaft to be damped. Damping boxes for the resilient and damped coupling of the seismic mass are attached, as replaceable components, to one of the secondary structural elements, preferably to a support disc for the seismic mass. At the interior of the damping boxes there is at least one fitted bolt or similar element, which extends under seal out of the damping box and is fixed to the primary member. This fitted bolt carries shear sheets which are plane parallel and perpendicular to the axis of rotation, and between which stationary metal sheets extend within and are connected to the damping boxes. The spaces between the shear sheets and the metal sheets are filled with silicon oil which is subject to alternate sheaving during relative movements of the sheets. The damping boxes are preferably located, at an angular distance from one another, between springs for guiding the primary and secondary members of the device.
