  • Patent number: 10584737
    Abstract: The ball socket assembly includes a housing that is made as a monolithic piece and has an inner bore. The ball socket assembly also includes a ball stud that has a semi-spherically curved portion, a cylindrical portion, and a shank portion. The ball socket assembly further includes a backing bearing and an exit bearing. A third bearing is received on the cylindrical portion of the ball stud. The third bearing has a curved outer surface which cooperates with the curved inner surface of at least one of the exit and backing bearings for allowing the ball stud and the bearing to articulate and rotate relative to the housing. The third bearing is also in slidable contact with the cylindrical portion of the ball stud for allowing the ball stud to more freely rotate relative to the housing about the central axis.

  • Patent number: 10363786
    Abstract: The socket assembly includes housing with an inner bore which extends along a central axis from a closed first end to an open second end. A ball portion of a ball stud is disposed in the inner bore of the housing, and a shank portion of the ball stud projects out of the housing through the open second end. A backing bearing is disposed in the inner bore and slidably supports the ball portion of the ball stud. A roller bearing or a pair of thrust washers is disposed in the inner bore of the housing and operatively supports the backing bearing to allow low friction rotation of the backing bearing relative to the housing.

  • Patent number: 9765840
    Abstract: 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.

    Abstract: A variable angle standoff in accordance with an implementation of the present invention includes one or more bearing interfaces, which, in concert with other beveled components (e.g., beveled rings), fastens about a wide range of panel and/or object dimensions. In one implementation, a threaded fastener is inserted through a first bearing interface, which interfaces with a first beveled ring. The threaded fastener further threads through one or more panel and/or object eyelets, through a second beveled ring, through a second bearing interface, and ultimately into a standoff shaft. Despite relatively tight fastening of the threaded fastener to the standoff shaft, the first and second beveled rings can accommodate object curvature by rotating in any of an X, Y, and/or Z dimension, as needed.

  • Patent number: 7249893
    Abstract: A rolling bearing and a rod end bearing are provided with a tilt mechanism and a rotary mechanism that are mutually independent. The tilt mechanism has a non-lubricated type spherical sliding bearing structure. The rotary mechanism has a rolling bearing structure which may or may not be sealed. By means of the non-lubricated type spherical sliding bearing structure, a tilt of the shaft center is made possible, and by means of a sealed rolling bearing structure, problems such as a lubrication oil leak are avoided, and carrying out high speed rotation and continuous rotation become possible. Because the sealed rolling bearing structure of the rotary mechanism does not call for a shaft center tilt function at all, the material of the seal can be chosen such that it emphasizes sliding resistance and high durability.
