  • Patent number: 9906095
    Abstract: A blocking device, and a gear-drive unit containing such a blocking device, and a method for producing such a gear-drive unit for blocking a rotary motion of a shaft relative to a housing of the gear-drive unit, having a first, rotatable blocking element and a second blocking element which is displaceable relative to the first blocking element by means of at least one electromagnet and at least one restoring element, in which the blocking elements in the blocked state mesh in the axial direction with one another by form-locking, and the blocking device is embodied as a separate, independent structural unit, which can be mounted as a unit on the one hand onto the housing and on the other onto the shaft.

  • Patent number: 8746421
    Abstract: A blocking device, and a gear-drive unit containing such a blocking device, and a method for producing such a gear-drive unit for blocking a rotary motion of a shaft (14) relative to a housing (16) of the gear-drive unit (10), having a first, rotatable blocking element (32) and a second blocking element (34) which is displaceable relative to the first blocking element (32) by means of at least one electromagnet (44) and at least one restoring element (42), in which the blocking elements (32, 34) in the blocked state mesh in the axial direction with one another by form-locking, and the blocking device (30) is embodied as a separate, independent structural unit (31), which can be mounted as a unit (31) on the one hand onto the housing (16) and on the other onto the shaft (14).

  • Patent number: 7768168
    Abstract: The present invention relates to an electrical machine having a rotor, a stator, and a permanent magnet located on the rotor. The permanent magnet is embodied essentially as a hollow cylinder with axial and/or radial contact faces and is secured to the rotor at the axial and/or radial contact faces by means of retaining elements; the permanent magnet is elastically supported in the axial direction (X-X) and/or the radial direction of the rotor by means of the retaining elements.

  • Patent number: 7649293
    Abstract: The rotor (1) of an electrical machine (10), having at least one permanent magnet (3), which is embodied as a hollow cylinder (5) and which has axial contact faces (20) that cooperate with corresponding axial clamping faces (22) of at least one retaining element (4), with which element the permanent magnet (3) is secured to the rotor (1), in which at least one of the clamping faces (22) has a knurling (46) extending in the radial direction.
