  • Patent number: 9175720
    Abstract: A ball joint with a ball pin and a steel ball pin with a joint ball. The ball joint and ball pin are suitable for use when, for example, solid-on-solid friction predominates under high static pre-loading or high operational loads and with small joint movements. A portion of the surface of the ball pin has surface layer hardening in order to increase a fatigue strength of the ball pin. The ball pin and the ball joint, on portion of the ball pin without the any surface layer hardened, includes a nitrided layer as wear protection. The ball pin and the ball joint provide an advantageous combination of high fatigue strength, good corrosion protection and high wear-resistance. The nitrided layer of ball joints, previously only regarded as improving corrosion protection, also functions as a wear protection. Thus, these ball pins overcome the mutual exclusion between surface layer hardening and nitriding.

  • Patent number: 7007901
    Abstract: The present invention provides a microphone support which includes a restriction groove 520 between a universal ball 50 and a mounting member 70 in order to restrict the rotating angle range of the universal ball 50 rotating with the axis line of a pipe through-hole 510 centered, so that the direction axis L of a microphone is restricted to have a designated swinging angle range with the talker side of the microphone centered. Therefore, no breaking wire by wire-twists is generated, and since the microphone is prevented from facing to loudspeakers owing to careless handling, no howling is also generated.

  • Patent number: 6915765
    Abstract: A variable compression piston assembly includes a plurality of pistons, a transition arm coupled to each of the pistons, and a rotating member mounted for pivoting movement to slide along an axis of the drive member. Movement of the rotating member relative to the drive member changes the compression ratio of the piston assembly. An engine assembly includes first and second piston assemblies mounted back-to-back and 180° out of phase. A joint for positioning between first and second pistons includes an outer member and an inner member. The outer member is configured for movement relative to the pistons along a first axis perpendicular to the common axis of the pistons. The inner member is mounted within the outer member for rotation relative to the outer member about a second axis perpendicular to the first axis and the common axis.

  • Patent number: 6776552
    Abstract: A ball joint which uses spherical rollers to reduce the torque friction which tends to inhibit the rotation of the ball within a ball joint assembly. Two sets of spherical rollers are captivated between the ball and two liner rings in the ball joint housing. The ball has two annular raceways which act as the inner raceways for the spherical rollers. Two liner rings have internal diameters which match the configuration of the spherical rollers and which act as outer raceways for the spherical rollers. The two liner rings have external threads and are installed into the housing which has matching internal threads.

  • Patent number: 6520682
    Abstract: A bearing assembly for a hitch link having a removable spherical bushing within a socket is arranged to be symmetrical about a plane dissecting the socket lengthwise of the link. The socket is formed with laterally extending protrusion to increase the socket strength at the location of the greatest tension forces. The socket is configured with an entry slot for the bushing that is normal to the length of the link so that the slot does not interfere with the area of the contact wear surface between the busing and the socket. Once the bushing is installed in the socket, a sleeve is inserted into a bore of the bushing. One end of the sleeve has a raised retaining lip and the opposite end of the sleeve carries a snap ring groove. A snap ring is seated in the groove and retains the sleeve in the bushing.
