Abstract:
1. A form-locking connection for compensating position errors, comprising: a first component; a second component to be connected with the first component; a first circular form-locking element associated with the first component; a second circular form-locking element associated with the second component; and a compensation element provided between the first circular form-locking element and the second circular form-locking element, wherein the compensation element is configured as a compensation ring, wherein the circular form-locking elements are fixated with respect to their axial positions and form a form-locking arrangement with the compensation ring which form-locking arrangement fixates the first component and the second component in contact with and relative to each other, wherein the first circular form-locking element is provided with a first spherical segment shaped cambered surface on its side oriented towards the second circular form-locking element, wherein a center of curvature of the first spherical segment shaped cambered surface is arranged on an axis of the first circular form-locking element, wherein the second circular form-locking element is provided with a second spherical segment shaped cambered surface on its side oriented in a radial direction towards the first spherical segment shaped cambered surface of the first circular form-locking element, wherein the first spherical segment shaped cambered surface and the second spherical segment shaped cambered surface overlap along a direction of the axis in a radial projection, wherein a center of curvature of the second spherical segment shaped cambered surface is arranged on an axis of the second circular locking element, wherein the compensation ring includes a third spherical segment shaped cambered surface whose curvature is adapted to the opposite first spherical segment shaped cambered surface and a fourth spherical segment shaped cambered surface whose curvature is adapted to the opposite second spherical segment shaped cambered surface, wherein the compensation ring includes a radial inside with an inner diameter which is provided with the radially inner third spherical segment shaped cambered surface, wherein the compensation ring includes a radial outside which is provided with the radially outer fourth spherical segment shaped cambered surface, wherein the radially inner third spherical segment shaped cambered surface of the compensation ring contacts the spherical segment shaped cambered surface of the first circular form-locking element in a spherical segment, wherein the radially outer fourth spherical segment shaped cambered surface of the compensation ring contacts the spherical segment shaped cambered surface of the second circular form-locking element, wherein the radially inner third spherical segment shaped cambered surface and the radially outer fourth spherical segment shaped cambered surface of the compensation ring are surfaces that are oriented away from one another in a radial direction, wherein a curvature center of the radially inner third spherical segment shaped cambered surface and a curvature center of the radially outer fourth spherical segment shaped cambered surface are offset from one another in axial direction, wherein the curvature center of the radially inner third spherical segment shaped cambered surface is closer to the compensation ring than the curvature center of the radially outer fourth spherical segment shaped cambered surface, and wherein the compensation ring is pivotable between the form-locking elements about an axis that does not coincide with an axis of rotation symmetry of the compensation ring so that contacting spherical segment shaped cambered surfaces of the form-locking elements and the compensation ring remain in contact with one another.
