Rotary joint arrangement and positioning device comprising the rotary joint arrangement and a linear guide device

A rotary joint arrangement (DGA), comprising

• a first part (15),
• a second part (70), and
• a coupling means (KE) comprising at least one solid body joint (80A, 80B) for connecting the first part (15) and the second part (70) in such a way that the second part is enabled to be rotated relative to the first part about an axis of rotation (DZ) extending in a first direction (Z),
• wherein the first part (15) and the second part (70) each have an extension perpendicular to the axis of rotation (DZ),
• wherein the second part is arranged relative to the first part so as to be offset by a distance axially to the axis of rotation (DZ),
• wherein
• the coupling means (KE) has a first solid body joint (80A) and a second solid body joint (80B),
• wherein the first solid body joint (80A) comprises a first elongate solid body, which extends perpendicular to the first direction (Z) along a first plane (ME1) parallel to the first direction (Z), and which has a longitudinal axis arranged perpendicular to the first direction (Z), wherein the first elongate solid body has the following longitudinal sections, which are arranged one behind another in the direction of the longitudinal axis of the first elongate solid body:
• a first end section (E1), which forms a first end of the first elongate solid body;
• a second end section (E2), which forms a second end of the first elongate solid body located opposite the first end of the first elongate solid body in the direction of the longitudinal axis of the first elongate solid body;
• a central section (F) arranged between the first end section and the second end section of the first elongate solid body;
• a first web part (S1) arranged between the first end section (E1) and the central section (F) of the first elongate solid body, connected to the first end section (E1) and the central section (F);
• a second web part (S2) arranged between the second end section (E2) and the central section (F) of the first elongate solid body, connected to the second end section (E2) and the central section (F) of the first elongate solid body;
• wherein the second solid body joint (80B) comprises a second elongate solid body, which extends perpendicular to the first direction (Z) along a second plane (ME2) parallel to the first direction (Z), and which has a longitudinal axis arranged perpendicular to the first direction (Z), wherein the second elongate solid body has the following longitudinal sections, which are arranged one behind another, in the direction of the longitudinal axis of the second elongate solid body:
• a first end section (E1), which forms a first end of the second elongate solid body;
• a second end section (E2), which forms a second end of the second elongate solid body located opposite the first end of the second elongate solid body in the direction of the longitudinal axis of the second elongate solid body;
• a central section (F) arranged between the first end section and the second end section of the second elongate solid body;
• a first web part (S1) arranged between the first end section (E1) and the central section (F) of the second elongate solid body, connected to the first end section and the central section;
• a second web part (S2) arranged between the second end section (E2) and the central section (F) of the second elongate solid body, connected to the second end section (E2) and the central section (F) of the second elongate solid body;
• wherein the first part (15) is connected to the second part (70) via the first solid body joint (80A) and the second solid body joint (80B) in such a way
• that the first end section (E1) of the first elongate solid body and the second end section (E2) of the first elongate solid body are rigidly connected to the second part
