Abstract
A damping bearing () including an inner ball portion () attached to an end of a support shaft (), and an outer collar portion () attached to a housing () for rotation of the housing relative to the support shaft about a center point. A chamber () 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 () 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 () of the shaft. It may provide only enough clearance for less than ±10 of relative rotation between the housing and shaft. A set-screw () may pressurize the fluid in the chamber.
