| 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). |

1. Energy guiding chain for guiding cables, hoses and the like 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 that can be pivoted relative to each other over a certain pivoting angle, each of which comprises two side straps displaying inner sides facing towards the interior of the chain, outward-facing outer sides and narrow faces running perpendicularly to them and in the longitudinal direction of the side straps, where the side straps form opposite strap strands transversely to their longitudinal direction, and at least some of the opposite side straps are connected to each other by cross-members, at least some of which display a bearing area on at least one of their ends that interacts with a bearing seat, located on the side strap facing towards said end of the cross-member, in articulated fashion for pivoting the cross-member between a closed position and an opened position, where the bearing area displays at least one journal of essentially cylindrical design, the axis of which is oriented in the longitudinal direction of the side strap, and the bearing seat displays a pocket-shaped journal seat with a space that corresponds to the journal, is essentially cylindrical and into which the journal can be inserted, characterised in that the essentially cylindrical journal on the fastening end of the cross-member displays a first flattened section on its lateral surface, where the first flattened section lies parallel to the axis of the essentially cylindrical journal, and the essentially cylindrical space of the bearing seat on the adjacent side strap, receiving the journal, displays a flattened section, where the latter and the first flattened section of the journal are arranged in such a way relative to each other that, in the closed position of the cross-member, the flattened section of the cylindrical space and the first flattened section of the essentially cylindrical journal are opposite each other. |
