  • Publication number: 20170284477
    Abstract: A connector arrangement is provided for centering two shaft sections to be connected with one another, having at least one outer connector having a longitudinal axis, and at least one inner connector disposed radially inward from the at least one outer connector, with reference to the longitudinal axis. The outer connector and the inner connector are connected by way of at least one elastomer body, which is connected with at least one sealing lip. The sealing lip is configured with a C profile, viewed in a cross-section that contains the axis, wherein one end of the C profile is connected with the elastomer body and wherein the other end of the C profile is configured as a free end for the purpose of coming into contact with a shaft section, forming a seal.

  • Patent number: 9400017
    Abstract: A bushing arrangement for centring two shaft portions to be connected, having at least one outer bushing, and at least one inner bushing arranged radially inwards of the at least one outer bushing, the at least one outer bushing and the at least one inner bushing being connected via at least one elastomer body, on which at least one sealing lip is formed. At least one encircling recess is formed in the elastomer body which extends from one axial end of the bushing arrangement in such a manner into the elastomer body that the at least one recess extends radially around the at least one sealing lip and around at least a portion of the axial extent of the inner bushing.

  • Patent number: 9097286
    Abstract: A coupling is provided for connecting two shaft sections in a damping manner, including a bushing arrangement having a radially inner bushing and a radially outer bushing, wherein the radially inner bushing can be coupled to a first shaft section and the radially outer bushing can be coupled to a second shaft section so as to transmit torque, wherein a damping layer is provided between the radially inner bushing and the radially outer bushing. The bushing arrangement can have a circumferentially wave-shaped contour, wherein the radially inner bushing and the radially outer bushing have shafts that mesh with each other, and wherein the damping layer is provided with axial openings, which extend reciprocally from both axial ends of the coupling into the damping layer so that damping blocks are formed at the axial ends of the coupling between the radially inner and radially outer bushings.
