摘要： A damping bearing (20) including an inner ball portion (34) attached to an end of a support shaft (32), and an outer collar portion (30) attached to a housing (22) for rotation of the housing relative to the support shaft about a center point. A chamber (28) for a damping fluid such as grease is defined by clearance between the end of the shaft and the housing. The fluid chamber has opposed bounding surfaces (29, 37) that are non-spherical about the center of rotation so that the chamber changes shape upon rotation of the bearing, thus shifting damping fluid across the chamber. The chamber may be a flat cylindrical void normal to a centerline (33) of the shaft. It may provide only enough clearance for less than ± 10 of relative rotation between the housing and shaft. A set-screw (26) may pressurize the fluid in the chamber.
