Abstract: A flexible coupling comprised of one or more flex frames connected in series between end fittings has the legs of its flex frames so dimensioned as to provide the coupling with a uniform bending stiffness with respect to bending moments in planes at all angles to the rotational axis. This is achieved by having each flex frame itself be of uniform bending stiffness with the other coupling components designed so as to have substantially no influence on the coupling's bending characteristics, or by using in the coupling at least one "compensator" flex frame specifically dimensioned to have a non-uniform bending stiffness compensating the non-uniform bending stiffnesses of the other coupling components.

Abstract: A flyer bow is presented for use with twisting machines to twist wires. The flyer bow has inner and outer surfaces, and at least one surface is curved to form an airfoil in cross section. The curved surface may be the outer surface or the inner surface. Both surfaces may be curved to form a symmetric airfoil. The inner surface has a wire receiving recess and a wear strip recess spanning the wire receiving recess. Aerodynamically shaped wire guides may be attached to the inner surface opposite to the wire receiving recess.

Abstract: A method of manufacturing an improved track roller bearing is presented in which the axial thrust bearing elements are integral inclined opposed surfaces formed on the inner and outer races of the track roller bearing. The inner race is swaged to form the inclined axial bearing surfaces on the inner race after the races are assembled. A self-lubricating material is bonded to the inner race, including the axial bearing inclined surfaces thereof, after the inner and outer races are assembled and the axial bearing surfaces are formed.

Abstract: A light-weight push, pull and/or torsion rod includes a light-weight core, fittings on either end, pins protruding from the outer surface of each fitting, and a tubular strength member surrounding the core and overlapping much of the end fitting. The strength member includes a fibrous braided layer which overlaps and closely captures the protruding tips of the pins to anchor the strength member to the end fitting. In one embodiment, the end fittings are conically tapered from the side adjacent the core and flare out from the narrow end of the cone, and the braid is woven tightly around the conical portion and flared portion of each end fitting so that the strength member abuts or bears against the end fitting when the rod is exposed to tension or compression forces.

Abstract: A flexible coupling includes a quadrilateral, flex member, which coupling rotatably couples a driving shaft to a driven shaft and accommodates endwise, parallel or angular misalignment between the shafts. The flex member includes corner portions each having one substantially aligned face and a raised face created by thickening of each corner portion. The substantially aligned faces of two diagonally opposed corner portions face in one generally axial direction and the substantially aligned faces of the other corner portions face in a direction generally opposite to that of the substantially aligned faces of the two diagonally opposed corner portions to minimize the endwise spacing required between the driving shaft and the driven shaft needed to insert the coupling. The decreased endwise spacing minimizes the bending moment on the flex member and facilitates the identification of the proper assembly orientation of the flex member within the flexible coupling.

Abstract: A flexible coupling for drivingly connecting two rotatable shafts or the like, and for use in applications where torque is transmitted only in one direction of rotation or where the torque transmitted in one direction of rotation is significantly greater than the torque transmitted in the other direction of rotation, includes a flex member consisting of four elongated flex elements fixedly joined together in a unitary rectangular arrangement. The two elements positioned on opposite sides of the rectangular arrangement are of substantially rectangular cross-sectional shape along a major portion of element length, and the elements of one such pair are thicker than the elements of the other pair. The flex member is connected between the two rotatable shafts in a manner which causes the thicker elements to be in compression and the thinner elements to be in tension during torque transmission in the favored direction.

Abstract: A flexible coupling for drivingly connecting driving and driven members and for accommodating both angular and endwise misalignment of such members comprises a plurality of quadrilateral flex frames arranged face-to-face along the central axis of the coupling. The two end frames are connected respectively to the driving and driven members through opposite corner portions of each such frame. Among the flex frames themselves, each frame is connected to the next adjacent frame by having two of its opposite corner portions rigidly connected to two opposite corner portions of the adjacent frame.
