<p>A damper (10) of vibrations of the viscous fluid type has a two-piece housing (16) of which a plate (21) is formed by a spinforming process (141). The formed plate (21) has a plurality of internal walls (32) of which at least a portion of the walls (32) are usable as bearing surfaces after being spinformed and require no further machining thereof. The damper (10) includes a plurality of individual bearings (26) for radially and axially positioning a rotatable weight (20) within the housing (16) to form preselected spaces (26) between the housing (16) and the weight (20). An annular supply chamber (27) and the preselected spaces (26) have a viscous fluid (28) disposed therein to provide a damping medium between the rotatable weight (20) and the housing (16).</p> |
