Self-adjusting Or Self-aligning, Including Ball And Socket Type, Bearing And Component Making Patents (Class 29/898.043)
  • Patent number: 10315476
    Abstract: A replacement ball joint assembly (10) adapted to be pressed into a previously used and possibly distorted receiving hole (26) in a suspension component such as a control arm (28). A socket housing (12) of the assembly (10) includes a plurality of generally annular, concentric knurls (36) each having a respective crest portion (38) and separated one from another by intervening relief grooves (40). The crest portions (38) of the knurls (36) may be tapered so as to provide a lead-in feature to minimize misalignment during a press-in installation operation. The knurls (36) are preferably softer than the control arm material so that they yield during press-in rather than further disfiguring or enlarging the receiving hole (26). Displaced material from the crest portions (38) of the knurls (36) flows into the relief grooves (40).

    Abstract: A stabilizer link and a manufacturing method therefor in which there is less concentration of stress, the stud releasing load is improved, and the accuracy of centering of the ring member is improved. A second subassembly is formed by inserting a ball seat of a first subassembly into a ball seat receiving portion of a housing and by arranging a ring member at an opening side of the ball seat. A stopper base portion is abutted to an opening end surface of the ball seat. An outer peripheral end portion taper surface has a taper shape in which a diameter is increased toward an opening side in an axial direction, in a stopper base portion and it is abutted to a slope portion for a stopper base of the housing. An opening side of the ball seat is pressed through the ring member by caulking inwardly a caulking portion.

  • Patent number: 7665927
    Abstract: The present invention is an improved swivel joint for use as part of a cable-guided fishing assembly. The swivel joint contains a bearing assembly comprising a series of ball bearings partially encased by an inner and outer race. During a cable-guided fishing operation, the inner and outer race exert a shearing, rather than compression, force on the ball bearing due to the unique configuration of the bearing assembly. This unique configuration increases the strength of the bearing assembly, and the corresponding strength of the swivel joint, without necessitating an increase in the outer diameter of the swivel joint.

The cover is constructed with a boss in its outermost circumference so that when assembling the ball joint, the bearing flange that is inserted in the interior of the box, that is closed by the cover, does not burst. Moreover, the bearing is maintained fixed to the assembling place as it is desired, for the perfect operation of the ball joint. The cover constructed in this manner functions as a limiting piece in the assembling process, so that, even if too strongly pressed upon the bearing flange, it may burst only the outermost part of the bearing flange preserving its major part, that will be retained between the recess provided in the interior of the ball joint box and the space immediately posterior to the boss constructed in the outermost circumference of the cover, thus keeping the bearing fixed to its place.
