Articulated coupling, conical threaded ring, method for the production of a mounting of a cutting tool which mounting can disengage when overloaded, as well as a method for energy conversion by means of an articulated coupling

A method for producing a mounting of a cutting tool, which mounting can disengage upon overload, on a tension-transferring and/or compression-transferring rod, the method comprising:

• providing the rod with an external thread,
• introducing the rod into a conical recess of the cutting tool,
• screwing a conical threaded ring with an internal thread onto the external thread of the rod such that the conical threaded ring is displaceable on the external thread of the rod in a longitudinal direction by means of a force,
• introducing the rod into a pressure plate.

A method for conversion of energy by means of an articulated coupling, the method comprising:

• providing at least one tension-transferring and/or compression-transferring rod, wherein the rod comprises an external thread;
• providing at least one pressure plate, said plate comprising a cutting tool, which comprises at least one blade and a central conically shaped recess;
• providing at least one conical threaded ring, which comprises an internal thread and is slit in a longitudinal direction;
• screwing the external thread of the rod onto the conical threaded ring;
• arranging the cutting tool on a conical external surface of the conical threaded ring;
• and
• pressing the conical threaded ring into the conically shaped recess, wherein in case of an overload force being applied to the pressure plate, said plate is displaced on the rod, and wherein the conical threaded ring is expanded and displaced translationally on the external thread.
