  • Coupling arrangement and coupling element
    Patent number: 9004215
    Abstract: A coupling arrangement having a rotational axis, about which the coupling arrangement can rotate, having: a first coupling element with an axially-extending flat-side spur toothing system having radially extending first teeth, a second coupling element with an axially-extending flat-side corresponding toothing system which engages axially into the spur toothing system and has radially-extending second teeth, and at least one means for bracing the first coupling element axially with the second coupling element, which coupling elements are fixedly connected fixedly to one another to rotate together about the rotational axis via the toothing systems to transmit torque. The teeth of at least one of the toothing systems have tooth tip lines that are curved convexly in the axial direction away from a tooth root.
