摘要： A 6-axis positioning system includes a base, a movable unit and six variable-length actuators. One end of each actuator is connected to the base, and the other end of each actuator is connected to the movable unit. The six actuators are divided into two groups each having three actuators. The actuators of the first group are arranged on the base within a region bounded by the actuators of the second group, and the actuators of the first group are arranged on the movable unit within a region bounded by the actuators of the second group. The lower end and the upper end of each of the three actuators of the second group are connected to the base and to the movable unit, respectively, by means of respective pivot fastening systems. The upper end of each of the three actuators of the first group is connected to the movable unit by means of a pivot fastening system. The lower end of each of the three actuators of the first group is connected to the base by means of a pivot fastening system that can be pivoted during adjustment operation of the 6-axis positioning system.

摘要： The invention relates to a brake device having a frame, at least one pair of mutually opposing braking elements, at least one actuation element in operative connection with each braking element, and a spring device, wherein each braking element has three joint sections which are arranged in a row and are connected to one another via flexure bearings, and the middle joint section of which has a contact section, and the two joint sections adjoining the middle joint section are each connected integrally to the frame via a flexure bearing, wherein a force is exerted on each braking element by means of the spring device, by means of which force the respective contact section can be pressed with a defined force against an element to be braked, and a force which counteracts the force exerted on the braking elements by the spring device acts on the braking elements by means of a continuous energy input into the actuation elements and, when the energy input into the actuation elements is absent, the force exerted by the latter on the braking elements is removed.
