• the cap 14 can be designed like the cap 14 described in connection with FIGS. 1 to 5 according to the first cap embodiment.
• the cap 14 according to the fourth cap embodiment can have the through hole 34 in the web 16 for the first fastening bolt 82 (see FIG. 15) approximately in the middle of a longitudinal extent of the cap 14 in the longitudinal direction LS of the gap 10.
• the through hole 36 between the two legs 6 for the first fastening bolt 82 can be designed approximately according to the position of the through hole 34 in the web 16 of the cap 14 arranged on the fastening eye 4.

• An extension 70 with a through hole 72 for the second fastening bolt can be formed on the fastening eye 4 at an angle 68 to the longitudinal direction LS of the gap 10.
• the angle 68 can in particular be in a range from approximately 0 ° to approximately 90 °, for example in a range from approximately 30 ° to approximately 60 °. As shown, the angle 68 can be approximately 45 °. In principle, the angle 68 can assume any value that is suitable for placing the extension 70 in a sensible and / or space-saving manner when attaching the anti-rotation device 1.
• the fastening by means of two fastening bolts 82, the first fastening bolt 82 engaging approximately centrally on the cap 14 in the longitudinal direction LS, can further contribute to the cap 14 being pressed uniformly in the depth direction TS of the gap 10 when fastening the anti-rotation device 1 and / or a contact of the inner flange surfaces 46 of the cap 14 with the outer wedge surfaces 40 of the legs 6 is as uniform as possible.
• FIG. 14 shows a three-dimensional view of a frame section, as shown by way of example a frame section of a roller conveyor, with a drive roller 2.
• a drive motor (not visible here) is installed in the drive roller 2, a stub shaft on the motor side being secured with the anti-rotation device 1 according to FIG. the anti-rotation device 1 is shown in FIG. 14 in the assembled state.
• the anti-rotation device 1 supports a torque of the drive motor against a frame 74 of the frame section.
• a connecting cable 76 for the drive motor protrudes from the stub shaft on the motor side.
• conveyor rollers 78 are in the frame section subsequent to the drive roller 2 arranged, which are driven by a belt drive 80 from the drive roller 2. Respective upper surface lines of the conveyor rollers 78 form a tangential plane on which goods or transport packaging such as cartons, pallets or the like can be conveyed as a transport plane.
• FIG. 14 the assembled anti-rotation lock 1 is shown in FIG. 14.
• the stub shaft is encompassed by the fastening eye 4 of the anti-rotation device 1, the cap 14 and thus the anti-rotation device 1 being fastened to the frame 74 by means of the fastening bolt 82.
• the fastening bolt 82 is inserted into the through holes 34, 36 (see FIG. 3).
• a fastening direction BB of the fastening bracket 82 preferably extends in the depth direction TS of the gap 10.
• the cap 14 is moved in the direction of the upper sides 52 of the legs 6 and the distance 56 formed before the anti-rotation device 1 is installed between the upper sides 52 of the legs 6 and the inner land surface 54 of the cap 14 is preferably reduced to zero in the assembled state of the anti-rotation device 1.
• Both legs 6 are compressed by the cap 14 in the width direction BS of the gap 10 and thus the gap 10 is preferably reduced to zero in the assembled state of the anti-rotation device 1, whereby a clamping force is exerted on the stub axle by the fastening eye 4.
• This clamping force ensures a reliable securing of the axle stub and prevents the so-called “knocking out” of the receptacle of the motor-side axle stub, which can be caused by an application of the torque of the drive motor in the drive roller 2.
• the anti-rotation device 1 can also be designed such that in the assembled state of the anti-rotation device 1 there is still a distance 56 between the web surface 54 and the upper sides 52 of the legs 6 and a gap 10 between the legs 6, the clamping force of the fastening eye 4 thus achieved the stub shaft on the motor side is sufficient to reliably secure the stub shaft on the motor side.
• the Anti-rotation device 1 can thus be adjusted in order to set a decreasing clamping force of the fastening eye 4 on the stub shaft on the motor side to the desired value or to increase the clamping force, for example in order to adapt the clamping force to an increased torque of the drive motor.
