摘要

The energy guide chain has chain links (1) with side link plates (2) which are rotationally elastically connected by connections or bearings. The rotationally elastic connections may be formed by claw couplings (3) which have a permanently elastic twistable connecting element (5) installed in the rotational axis, and claw-like protrusions (6) formed on the link plates. The protrusions engage in pockets (7) in the adjacent link plate and are movable between stops (4) defined by the pockets, and transmit tensile and compressive forces acting in the chain's longitudinal direction.
