A bolt joint in an industrial robot for fixing a first body (1) to a second body (2). The joint allows a non-play transmission of a torsional force acting between the bodies. An expandable conical first sleeve (8) makes contact with a hole wall of a cylindrical hole (7) common to both bodies. The joint also comprises a conical second sleeve (9) which is adapted to penetrate into the first sleeve (8). A bolt (3) is arranged running coaxially through the sleeves. When the bolt is clamped, the second sleeve (9) penetrates, with force, into the first sleeve (8) and forces the first sleeve (8) to expand. The strong expansion results in the first sleeve (8) deforming deviations in the hole (7), such that it makes butt contact with the common hole wall. |
