Definitions

  • the invention relates to an energy guide chain for guiding hoses, cables or the like with a plurality of links which are each articulated to one another by means of articulated connections and each have two opposite side parts with inner and outer side surfaces, at least some of the links connecting at least one of the side parts of a link Have cross bar, so that through the side parts and the cross bars of the chain, a chain interior with a cable guide channel is provided, the links further having paired abutment surfaces to limit the pivoting angle of adjacent links against each other.
  • Such energy chains are used to guide hoses, cables or the like between two consumers, at least one of which is movable.
  • particularly flat chain links are desirable, for example if a large number of cables, hoses or lines arranged next to one another are to be fed to a consumer in a single-layer arrangement, or if the spatial conditions so require.
  • some of the links can have a very large width and / or high travel speeds of the energy chain are desirable, so that the chain as a whole is exposed to great forces. Due to the flat links, which must strike each other and absorb forces when the chain is deflected, the possible uses of the chain are limited.
  • the invention is therefore based on the object To create an energy chain that can be exposed to high forces and travel speeds even with very flat links and that can be operated safely and reliably.
  • an energy chain in which the ratio of the width to the height of the side parts of the links is greater than / equal to 1: 4 and the link connections of adjacent links are bridged as adjacent links and are deformable when the chain is deflected, and wherein the Links each have adjacent faces facing the adjacent links, which extend continuously over the entire width of the side parts without step-like structures and- • function as stop faces.
  • the articulated connections are designed as deformable articulated elements that bridge the adjacent links and preferably extend in the longitudinal direction of the chain, the articulated elements can absorb high loads even at very low heights, while at the same time otherwise known pin-and-tenon joints that are used with very flat links and high forces have proven to be no longer appropriate.
  • the wide links above and / or below the articulated connections can provide large stop surfaces for the links, so that the links can absorb high forces despite their height, in particular when the chain is moved into its extended position.
  • the term “above” is understood here and in the following to refer to the links of the upper run, so that the “upper narrow surface” of the links faces away from the opposite run and the “lower narrow surface” of the links faces the respective opposite run the end faces of the side parts facing the respectively adjacent links are designed to be continuous over their entire width, so that the side parts come into abutment with one another over their entire width Stop surfaces no offset, in particular step offset and are preferably flat, optionally also arched.
  • the opposite side parts overlapping areas can be dispensed with, whose extension in the chain longitudinal direction is greater than / equal to H or corresponds to half the width of the side parts.
  • the combination of the above-mentioned features thus provides an energy guide chain which can absorb high forces even with very flat links, which enables both comparatively wide chain links and high chain travel speeds.
  • the links can easily have a height of less than 2 to 3 cm, for example a height of less than / equal to 1.5 cm or approximately 1 cm or less.
  • the ratio of the width to the height of the side parts can be less than or equal to 1: 3, for example approximately 1: 2 or less.
  • the ratio of the width to the height of the links can be greater than / equal to 2: 1, in particular greater than / equal to 3: 1 or greater than / equal to 4: 1 to 5: 1.
  • the ratio of the width to the height of the stop surfaces can be greater than / equal to 1: 2, in particular greater than / equal to 3/8, particularly preferably greater than / equal to 3/4. Due to the large width of the side parts, it is advantageous if they have recesses within their cross-sectional contour which are open to the inner and / or outer, preferably only to the outer side surface of the side parts and whose depth is greater than / equal to 50% or greater than / equal to 75% corresponds to the side section width. The extent of the recesses is essentially limited only by the resulting stability of the links.
  • the recesses are preferably delimited by a closed, peripheral edge. Regardless of this or at the same time, the recesses can be at least partially or completely delimited from the joint elements by an edge region, the edge preferably extending over the entire longitudinal extent and preferably also the entire width of the side parts.
  • the recesses can only extend above and / or below the respective articulated connections of the links.
  • the joint elements can be guided and held along their extension area over the side parts in the chain longitudinal direction on the upper and / or lower side on corresponding guide areas of the side parts.
  • the guide areas of the side parts which can be designed in particular as the edge area of the recesses, preferably lie closely and without play on the joint elements, in particular in a press fit.
  • the edge which delimits the recesses and which is arranged above and / or below the joint elements can be made thin in such a way that it extends to the joint element except for a holding area necessary for fixing the joint element.
  • the thickness of this holding area can be less than or equal to three times, twice or once the thickness or diameter of the joint element, for example the height of a flat joint element or hinge.
  • the recesses can be a occupy the largest possible extent, at the same time always ensuring an exact and secure mounting of the joint elements if they extend past the side parts.
  • the thickness of the edge which otherwise surrounds the recess can also be less than / equal to three, twice or one thickness of the joint element.
  • the joint elements can generally connect two or more links to each other in the longitudinal direction of the chain, the joint elements preferably each being fastened to the respective link in a way that absorbs tensile force.
  • the joint elements preferably extend between the end faces of the adjacent links.
  • the tensile force-absorbing connection of the joint elements to the links can be achieved by undercut areas, which are preferably provided on the links, in particular on the side parts, and are engaged behind by holding areas of the joint elements.
  • the articulated elements in the chain longitudinal direction and / or in the chain transverse direction are secured against displacement on the links, in particular on the side parts, and in particular are held in a press fit for this purpose.

  • the joint elements if they are over several links extend, have a holding area, for example in the form of a cross-sectional widening, on each area facing the adjacent link, thereby ensuring a secure fit of the joint elements.
  • a broad configuration of the joint elements is expedient, since the side and / or torsional stability of the chain is largely or exclusively determined by the joint elements. This applies in particular when the links do not have any areas that laterally overlap with one another over all or a larger part, for example more than 75%, of the pivoting angle.
  • the joint elements can also be designed as an articulated band arranged on the crossbars and / or undersides of the side parts, which connects several links and can extend continuously over the chain length.

  • the joint elements on the one hand and the side parts or links on the other hand can thus consist of different materials, in particular plastic materials.
  • the side parts preferably have end-side recesses which are provided above and / or below the joint connections and extend as far as the joint connections, the recesses being able in each case to widen in the direction of the joint connections.
