ABSTRACT:
A damper of vibrations of the viscous fluid type has a two-piece housing of which a plate is formed by a spinforming process. The formed plate has a plurality of internal walls of which at least a portion of the walls are usable as bearing surfaces after being spinformed and require no further machining thereof. The damper includes a plurality of individual bearings for radially and axially positioning a rotatable weight within the housing to form preselected spaces between the housing and the weight. An annular supply chamber and the preselected spaces have a viscous fluid disposed therein to provide a damping medium between the rotatable weight and the housing.
