Articulation for connecting two link shafts

摘要

The facing sections (7,8) of the free ends of the shafts are congruent to one another and locate on one another in a flat manner. The congruent section (7) of the free end of the one link shaft (1) is formed as a cavity in a surface (11) crossways to the longitudinal extent of the shaft. The congruent section (8) of the free end of the other link shaft (2) is formed as a projection (10) from a surface (9) crossways to the longitudinal extent of the link shaft (2). The cavity and the projection have a somewhat hemispherical shape. A lubricating device is provided for the sections (7,8).
