BALL HINGE AND METHOD OF MAKING SAME Russian patent published in 1996 - IPC

FIELD: mechanical engineering. SUBSTANCE: ball head 4 is enclosed by a housing made up as clamp 1. The shelves of the clamp are tightened with screw 5. Spherical hollows 7 are provided on the inner surfaces of the clamp at the ball head. The housing can be made up as two clamps. The shelves of the clamps can be provided with openings 6 whose diameter is less than the diameter of the ball head. To make the hinge ball head is interposed between the clamp shelves and a deformation force is applied to the clamp to define spherical hollows. Being loosened the shelves are tighten with a screw to provided control of a gap in the ball hinge. EFFECT: improved design and simplified assembling. 3 cl, 3 dwg
