Device for securing a tension element against unintentional release

A device for securing a clamping element against unintentional release, comprising:

• a disk-shaped structure penetrated by a non-circular inner contour, the non-circular inner contour defining an axis, the disk-shaped structure having a surface with a driving profile defined by the non-circular inner contour, the disk-shaped structure positionable on a component such that the driving profile engages a profile on the component to establish a torque-proof coupling of the disk-shaped structure and the component about the axis, the disk-shaped structure having a pair of contact surfaces, each contact surface of the pair of contact surfaces running radially and positioned at a respective axial side of the disk-shaped structure,
• wherein at least one profile plane of the driving profile is tilted at an angle with respect to a radial plane of each contact surface of the pair of contact surfaces,
• wherein the profile plane of the driving profile is perpendicular to the axis, and
• wherein the driving profile is defined by the non-circular inner contour such that the inner surface is constant along the axis.

A mounting arrangement, comprising:

• a shaft;
• a clamping element on the shaft such that the clamping element produces a pre-tensioning acting in an axial direction;
• and
• a device pre-tensioned in the axial direction by the clamping element, the device comprising
• a disk-shaped structure penetrated by a bore hole, the bore hole defining an axis, the disk-shaped structure having an inner surface with a driving profile defined by the bore hole, the disk-shaped structure having a pair of contact surfaces, each contact surface running radially and positioned at a respective axial side of the disk-shaped structure,
• wherein a profile plane, along which the driving profile extends, is tilted at an angle with respect to a radial plane of each contact surface of the pair of contact surfaces, one of the pair of contact surfaces positioned on the clamping element and the other of the pair of contact surfaces positioned on an additional component, the driving profile of the disk-shaped structure engaging in a torque-proof manner a profile of the shaft about the axis, the profile of the shaft having a clearance fit corresponding to the driving profile when the device is not pre-tensioned, the driving profile tilted to the angle by the clamping element relative to the profile of the shaft such that no backlash is present between the driving profile and the profile of the shaft in at least one area in a circumferential direction,
• wherein the profile plane of the driving profile is perpendicular to the axis, and
• wherein the driving profile is defined by the bore hole such that the inner surface is constant along the axis.
