Energy guiding chain

摘要

The invention relates to an energy guiding chain, with chain links (1, 2) each comprising two side straps (3, 4). The side straps (3, 4) form opposite strap strands transversely to their longitudinal direction, where at least some of the opposite side straps (3, 4) are connected to each other by cross-members (5, 6), the ends of at least some of which display a bearing area (7) with an essentially cylindrical journal (10), extending in the longitudinal direction, for pivotable mounting in a bearing seat (8) on an associated side strap (3, 4). To improve the angular stability of the side straps when the cross-member is opened, it is proposed that the journal (10) display a first flattened section (12) on its lateral surface. To receive the journal (10), the bearing seat (8) comprises an essentially cylindrical space (13) with a flattened section (15), where the flattened section (15) of the cylindrical space (13) and the first flattened section (12) of the journal (10) lie opposite each other in a closed position of the cross-member (5, 6).

主权项

1. An energy guiding chain for guiding supply lines from a first connecting point to a second connecting point that moves relative to the first connecting point, comprising:
a plurality of plastic chain links pivotable relative to each other over a pivoting angle, each plastic chain link of the plurality of chain links comprising two side straps, each side strap of the two side straps having an inner side facing towards an interior of the chain, an outer side facing outwards from the chain and opposing narrow faces arranged perpendicular to the inner side and the outer side and extending in a longitudinal direction of the side strap, wherein the side straps form opposite strap strands transverse to the longitudinal direction, wherein at least some of the side straps of the opposite strap strands are connected to each other by a cross-member, wherein at least one end of the cross-member includes a bearing area that interacts with a bearing seat located on an adjacent side strap facing towards the end of the cross-member having the bearing area in articulated fashion, for pivoting the cross-member between a closed position and an a completely opened position, wherein the bearing area includes at least one journal, wherein the journal has an axis oriented in the longitudinal direction of the side strap, wherein the bearing seat includes at least one pocket-shaped journal seat having a space to receive the journal, and the journal is insertable into the pocket-shaped journal seat, wherein the journal has a first flattened section on a lateral surface, and the first flattened section of the journal is parallel to the journal axis, wherein the journal seat of the bearing seat on the adjacent side strap to receive the journal includes a wall having a flattened section, and wherein the flattened section of the journal seat and the first flattened section of the journal are arranged such that, in the closed position of the cross-member, the flattened section of the journal seat and the first flattened section of the journal are opposite each other.
