Abstract: A joint for the angularly movable connection of two shafts with one another has flanges which are arranged on the shaft ends. Each of the flanges has three axially projecting driving pins which are connected with a hexagonal, elastically deformable joint ring. The joint ring, in turn, is formed in several parts by a collar of chain-link-type driving loops which can be swivelled on sockets at the corner points of the joint ring.

The compression bar has faces placed onto the sockets while transmitting force under load. The effective length of the compression bars is dimensioned such that the bars fill the clear space between two adjacent sockets only with play. The play is large enough so that the compression bars are placed in contact only after a defined basic load has been exceeded so that as the result of the load, the driving loops are elastically stretched to a defined degree.

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 method of forming flexible disks containing annular loop packets for the purpose of transmitting traction forces between fastening elements is disclosed. The loop packets and the fastening elements are combined into a ring and subsequently embedded in rubber-elastic material. In a preparatory operation, the loop packets are injection-coated either individually or in groups by a coating of elastomer material, which defines and stabilizes their outer contour. The elastomer material is only partially vulcanized before the ring is completely embedded in the rubber-elastic material. Injection coating renders the loop packets or groups of loop packets into components which are true to shape and size with defined wall thicknesses. Consequently, the characteristics and the life of the flexible disks are standardized for mass production and material consumption is reduced.

Abstract: A flywheel clutch assembly disposed between an engine and transmission includes an external damper positioned between a flywheel and a clutch housing. The external damper allows relative motion between the flywheel and the clutch housing, while elastically resisting relative motion in both the driving and coast modes. The clutch housing is relatively heavy and functions as an additional flywheel as it is being rotated by the main flywheel of the assembly. The clutch mechanism disposed within the housing includes a rigid driven disk which assures minimum inertia in the drive line. In one specific aspect of the invention, the damper is comprised of a plurality of arcuate, nested beam springs pivoted at one end to the flywheel and at the other end to the heavy cover enclosing the clutch assembly. The resulting flywheel clutch assembly with the external damper disposed between the flywheel and clutch provides improved shiftability while minimizing rattle in both the idle and drive modes of the drive line.

The coupling includes a series of preloaded endless belts embedded in an elastomer matrix material, arranged tangentially with respect to the connected shafts and connected thereto by bobbin-like spools at the ends of the belts. The endless belts are axially stiff to accommodate tensile and compression loads and are flexibly and torsionally soft to accommodate the motion while transferring torque between the drive and driven shaft.

Abstract: The tie-bar comprises a pair of spaced apart bushings each having end flanges extending from a central cylindrical portion and a through opening for connecting to flexing structures. A plurality of wires comprising bands of parallel wires wrapped endlessly about the spaced-apart bushings provide a tie-bar having bushings disposed at the ends and connected by a pair of spaced-apart side portions of superimposed bands. The wires are coated with a dry film lubricant so that the wires are dry wrapped about the bushings, and then a resin material encapsulated about the dry wrapped wire bands and bushings. A body of resin material disposed between the spaced-apart side portions and the bushings maintains the spaced-apart relationship of the bushings, by withstanding the compressive tension of the tightly wrapped wires. The wires are free to move relative to one another in response to tension and torsional forces exerted upon the tie-bar.

Abstract: A flexible all-steel shaft coupling with two connecting flanges which are connected by a laminated spring ring arranged between them. The laminated spring ring is arranged on clamping bolts by clamping bushes and is held at a distance from the flanges by spacer collars. A washer with a low-friction coating is arranged between the laminated spring ring and each of the spacer collars. The washers prevent the upper lamellae from wrapping as a result of the rotation of the spacer collars during the bracing of the laminated spring ring, this being the cause of premature breaking of the lamellae.

The coupling rods are connected through torsion layers to coupling arms which are articulated to each other. One of the coupling rods or coupling arms are connected to their respective collars while the other of the coupling rods or coupling arms are connected to an intermediate member located between the two collars.

The laminated elastomeric bearings accommodate the motion of each link while transferring torque between the shaft and hub.

Abstract: A dual coupling (1) comprises two elastic and articulated couplings (2 and 2a) interconnected by a hollow, intermediate shaft (3). Each one of the couplings (2,2a) contain an outer half (4,4a) with a hub (5,5a) from which extend several arms (6). Between them sit more arms (6a) of the intermediate shaft (3). With its arms (6a), the intermediate shaft represents the inner halves of the couplings (2,2a). The ends of the interacting arms (6 and 6a) are interconnected by rubber-elastic connecting rods (7) so that two rows (8) of arms are provided on bolts (10) to the left and right of the arms (6 and 6a) forming a joint plane. Therefore, two joint planes are present. While the connecting rods are connected to the bolts (10) in form closing fashion, the bolts are fixed or articulated in the arms (6 and 6a). One hub ( 5) is connected to a solid axle (15) and the other hub (5a) to a hollow shaft (18).

Abstract: A flexible power transmission coupling wherein a drive member is connected to a driven member by a link assembly. The links are stacked and connected in series. Each link has a first end, a second end and an intermediate part. The first ends of each link are connected together and to the driven member, the second ends of each link are connected together and to a driven member or vice versa. The intermediate part of each link is convoluted and narrower than the ends. This allows greater axial and angular misalignments between drive and driven members. Also this results in a more linear relation between axial force and deflection of the coupling.

Abstract: A coupling comprising two hubs (1) elastically joined to a hollow shaft (2), which surrounds the hubs, by six elastically resilient links (3) which are bolted alternatingly in an hexagonal pattern to a hub flange (10) and a shaft flange (20) at the ends of the coupling. This permits parallel and angular misalignments according to the cardanic principle while torque is being transmitted. Because the flanges lie in the same transverse plane, the coupling is protected against slipping in the event that the resilient link elements should fail. Because the links are externally mounted, they permit optimum cardanic motion. The hubs may be fitted inside the hollow shaft (short configuration) or they may bolted on so as to project beyond the ends of the hollow shaft (long configuration).

Abstract: A coupling has input and output members interconnected by two-link coupling elements which are flexible in the plane of rotation by centrifugal force acting on them as the coupling rotates and by the torque transmitted. The coupling is soft over a range of speeds and torques.The input member is constructed from two metal spinnings welded together to form a housing which supports the pivot of each coupling element at both ends. The output member is similarly constructed with bushes welded on to support the pivot also at both ends. The pivots are axially free within limits increasing the axial misalignment capability of the coupling. A spring arrangement to buffer the links if they rapidly approach their stops is provided.

Abstract: A flexible shaft coupling comprising drive side connecting elements and driven side connecting elements arranged alternately and equidistantly in an annular orientation, and coupling pieces of annular form linking mutually adjacent pairs of drive side connecting elements and driven side connecting elements, each of both connecting elements being formed of an inner sleeve, an outer sleeve and an elastic intermediate member bonding them, the coupling pieces being formed of a belt strip wrapping around the outer sleeve and an elastomeric body surrounding and covering the wrapped belt strip. The elastic intermediate member is formed as a rubber bushing press-fitted between the inner and outer sleeves and extends only in an axially middle portion of both sleeves, and adjacent to the rubber bushing, intermediate sleeves are fitted to the inner sleeve or outer sleeve. The elastic intermediate member has a compressive strain of 25-40%.

Abstract: A flexible all-steel shaft coupling has two coupling halves each comprising a connecting flange and which are axially and angularly movable but antitorsionally connected to each other through a yieldable stapled lamella crown connected to the connecting flanges. Each connection of the stapled lamella crown with one of flanges consists of a bolt on which rests, in clamped position between spacer rings, the stapled lamella crown on a spring collet provided with a conical press seat. Due to its conical support on the bolt, the conical spring collet is radially expanded and transmits radial pretension into bores of the stapled lamella crown. Due to the tolerance-free support of the stapled lamella crown on the bolt, and due to radial pretension in the bores of the stapled lamella crown, the shaft coupling may be easily mounted without precision machning and without tolerance on the support seats, while expansions and ovalizations of the bores, which lead to ruptures due to notch corrosion are prevented.

Abstract: A shaft coupling working on the principle of an Oldham's coupling in which rotary members are connected by pairs of guide links (20,26). Additional guide links (28,38), displaced at an angle of 90.degree. to one another, are provided between the first rotary member (14) and the intermediate member (16) and between the intermediate member (16) and the second rotary member (18). The pivotal axes of the additional guide links extend in a crossed direction to the rotational axis of these members. These additional guide links provide resistance against axial forces in the coupling but do permit the coupling to operate with radial misalignment of the input and output shaft.

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 link coupling having at least one coupling hub and one outer coupling flange interconnected by links or groups of links which are disposed at a tangent to the rotational axis.
