ABSTRACT:
A rotation joint has two joint elements arranged for rotation with respect to each other about an axle, a cam ring arranged coaxial to the axle in a housing and having a curved track with a spatial curvature, a spring guide element arranged on the axle with springs disposed coaxial to the axle around the spring guide element, and bolts mounted radial to the axle and having bearings whose outer circumference lies in force-transmitting relation on the curved track. In order to make a rotation joint with weight compensation which guarantees sure functioning, and at the same time can be produced economically by a simple construction and a compact structure, the housing is essentially formed by the two joint elements. The spring guide element is rigidly connected with a first joint element, and the cam ring is arranged on the spring guide element and capable of axial motion, but the second joint element is locked against a movement in the direction of the axle, and the bolts are fixed in the second joint element.
