  • Patent number: 10087993
    Abstract: A claw coupling includes two coupling elements disposed in opposite relationship and having confronting end face surfaces from which claws engage alternately into one another. A pressure body ring, disposed between the two coupling elements, includes a ring element and pressure bodies which project radially outwards from the ring element and are respectively received between two adjacently disposed claws of the coupling elements. Some pressure bodies have each an axially projecting spacer with a contact surface which, when a predefined torque is transmitted via the claw coupling, is pressed against a contact surface area of the end face surface of an adjacent coupling element. The contact surface area is slanted or curved such that, in a no-load state of the claw coupling an axial distance between the contact surface of the spacer and the contact surface area of the end face surface increases in a radially outwards direction.

  • Patent number: 7931538
    Abstract: A torque dampening compensator for a vehicle including an isolator member disposed between an input member and an output member. The isolator member includes isolator elements disposed between corresponding lugs of the respective input and output members. The lugs of the output member have a draft angle, and the isolator elements have contact faces corresponding to the respective lugs with unequal axial depths to induce a moment on each isolator element that counteracts a thrust load between the input and output members initiated by the draft angle. One isolator element of the isolator member is formed to have a size corresponding to the space provided between adjacent lugs of the input and output members and a shape that is dissimilar from the space. The one isolator element is resiliently deformable into the space.

  • Patent number: 7744473
    Abstract: An adapter device and a production series of adapter devices for connecting an input shaft, e.g., a motor shaft of a motor, e.g., an electric motor, to a device to be driven, e.g., to a pinion of a gear unit, including an adapter shaft for the rotatably-fixed connection to the device to be driven, an intermediate piece engaged with the adapter shaft, and a sub-component that is engaged with the intermediate piece and is detachably connectible with form-locking to an input shaft, particularly a motor shaft. The sub-component includes a bore hole for accommodating the input shaft in the sub-component, and the sub-component has at least three claws for forming the coupling. The adapter shaft, at its second end, thus at the end facing the intermediate piece, has at least three claws for forming a coupling. The intermediate piece is provided between the claws of the sub-component and the claws of the adapter shaft.

  • Patent number: 7632188
    Abstract: A pair of spherical gears connects the intersecting shafts of a CV-joint. One gear has internal teeth, and the other has external teeth. The gear design is based on pitch circles that are great circles on theoretical pitch spheres that are concentric and have identical radii. The internal teeth are either conically or spherically shaped, while the external tooth faces are cylindrical with tangential flat extensions. The spherical gears are shown on half-shafts. The preferred embodiments have six teeth on each gear, and one preferred embodiment also uses balls for the internal teeth. The gears, while rotating at high speeds under load, can intersect throughout a continuous maximum range of 60° or more in any direction.
