This application is a locking mechanism in a banknote processing machine. While shutting, a lid should be pulled against a counter force. The drawing is undertaken by a motor-driven trapezoidal threaded spindle, which is used with a cushioned spindle nut in the closing process. The spindle nut should not twist with the threaded spindle both while attaching and mounting the spindle nut on the threaded spindle and during the further linear movement.
The problem was solved with a double joint made of igubal® angle and axial joints. The double joint enables all necessary degrees of freedom and also absorbs the tensile strength.
