It comprises drive side collars and driven side collars arranged equidistantly on a concentric circle and alternately; belt-like fiber bundles wrapping around adjacent collars; and an elastic material embedding the collars and the belt-like bundles. Cylindrical parts of the collars are integrally formed, on outer peripheries thereof with plural flange parts for holding the belt-like bundles and fitted to inner cylinder members. A central area of each of the inner peripheries of cylindrical parts is formed as a radially expanded portion from the other portion.

  • Publication number: 20030125114
    Abstract: A flexible coupling is provided to connect a flange on a drive shaft to a flange on a driven shaft. Circumferentially spaced fastening means provide bores through the coupling through which bolts can be passed to connect it alternately to the one and then the other flange. Adjacent fastening means are interconnected by link and washers are positioned at opposite ends of the stack of links at each fastening means. In accordance with the invention the washers are formed with peripheral grooves which will be entered by the plastics material forming the body of the coupling, thus locking the washers against being expelled when bolts are subsequently passed through the bores.

  • Patent number: 6371858
    Abstract: A cardan-type joint has flanges which are arranged on mutually facing shaft ends and preferably have three axially projecting driving pins, respectively, which are mutually staggered and uniformly arranged on the circumference of a common graduated circle. The driving pins are connected with one another in a torsion-proof manner by a flexible joint ring which is provided in corner points with sockets for the driving pins. The multi-part joint ring is formed by a collar of several oval driving loops. Each of the driving loops winds around two adjacent sockets. In order to easily permit relatively large bending angles during rotation, even in the event of a high mechanical and thermal loading of the cardan-type joint, the oval driving loops are indirectly or directly swivellably disposed on the driving pins by a pair of contact surfaces which are round in a meridian section in an axially slidable manner on the socket or on the driving loop.

  • Patent number: 6325722
    Abstract: The invention relates to a coupling for attaching a pair of longitudinally aligned, rotatable shafts. In one embodiment, the coupling has a pair of circular hubs having a bore through a central axis thereof. Suitable means fix a shaft within each bore. Several circular apertures are spaced around and through each hub and a hollow bushing is positioned in each circular aperture. A circular power ring is positioned between the hubs, the ring has several rounded coupling pins extending outwardly from its front and rear surfaces. Each pin is mounted within a corresponding one of the hollow bushings. In another embodiment, the coupling has the pins extend inwardly from each hub and the corresponding apertures are through the power ring. The hub pins are mounted within a corresponding one of the hollow bushings through the power rings. The invention also relates to an assembly comprising a coupling as described above, and a shaft fixed within the bore of each hub of the coupling.

  • Patent number: 6203434
    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. For relieving the driving loops, one linear compression bar is also arranged in the interior of each driving loop. 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.

  • Patent number: 6179716
    Abstract: The present invention provides an eccentric shaft coupling having a high durability, capable of dealing with a great torque load and transmitting correctly rotational movement. Two pairs of protrusions of cylindrical boss flanges secured to extremities of two rotating shafts are linked through an intermediate disk with phases shifted by 90° from each other. The intermediate disk is made of a material having a satisfactory strength and rigidity. Each of the two pairs of protrusions is put slidably between plane portions of two liners, each having a partial cylindrical shape, whose cross section is enclosed by an arc and a secant, inserted dismountably into a cylindrical cavity along inner walls to be guided. Only the liners, each having a partial cylindrical shape, whose cross section is enclosed by an arc and a secant, are subjected to strong wear and therefore, when they are worn, they can be easily exchanged.
