Robot arm comprising a transverse articulation between two segments of the manipulator arm, or between a segment and a terminal tool

摘要

The arm has an anterior segment (1) with an end provided with articulation units including a yoke, where yoke has wings (3) fixed at the segment. A pivoting sleeve (4) is mounted in rotation along a transversal articulation axis (X) and provided between the wings. Each wing receives concentric reducers (20) extended concentrically to the axis, where each reducer has a body (25) fixed to the associated wing and an outlet unit (24) coupled to the sleeve. An inlet unit (21) of the reducer is coupled to a transversal shaft (14) that is extended along the axis and driven by a remote motor unit.
