- the chain links preferably have a guide lug on at least one side, wherein the spacer lug is arranged between guide lugs and lugs or guide lugs and counter lugs. It can be arranged within a chain link several Distanzlaschen. It is preferably provided that the spacer flap has an enveloping contour in the chain running plane, which is smaller than the enveloping contour of the tabs and / or counter-tabs. Alternatively it can be provided that the spacer flap has an enveloping contour in the chain running plane, which is greater than the enveloping contour area of the teeth of the tabs and / or the counter-tabs in the region of the teeth of the tabs and / or counter-tabs.
- the spacer tab may have two holes, each receiving a hinge pin.
- the spacer plate may have an opening which receives both hinge pins in the manner of a slot. It is preferably provided that the spacer plate has two openings, each with an opening, which allow attachment of the spacer tab in the manner of a clip. Preferably, it is provided that the openings are arranged on the side facing away from the teeth of the link chain.

- Fig. 2 is a plan view of a plate chain according to the prior art with Zweilaschenv.
- the link chain 1 comprises a plurality of tabs 2 and counter tabs 3.
- the tabs 2 and counter tabs 3 are each arranged alternately and connected to hinge pin 4 as a hinge.
- Both ends of a tab are thus connected by means of a joint with one or two counter-tabs, correspondingly both ends of a counter-tab are connected by means of a hinge with one or two tabs.
- the hinge pin 4 may be in one piece, but are preferably in two parts, wherein a rocker 5 is associated with each of the tabs and unrolls on one of the mating tab 2 associated rocking piece 6.
- the rocker pieces 5, 6 each have a rolling profile 7 or T with which they can roll or slide on one another.
- the rolling profiles 7, T may be identical or different. Transverse to the direction L, this is in Fig.
- the tabs 2 and counter-tabs 3 can be identical components, a distinction between tabs 2 and 3 counter tabs is then visible only through the arrangement.
- Fig. 2 a stack of three tabs 2 and two opposing tabs 3 is shown, but here also stack with any other number of tabs 2 and 3 counter-tabs can be provided.
- the lugs 2 are - as can be seen in Fig. 1 - each provided with teeth 9.
- the link chain 1 with a toothing, z. B. a gear, comb.
- the division between flaps 2 and counter-flaps 3 is designed so that a uniform pitch between the teeth 9 results in total when the chain is stretched.
- the counter-tabs 3 may be provided with teeth 9, so that all tabs and counter-tabs are each provided with teeth. Likewise, it is possible to provide each laugh and opposing tabs with only one tooth.
- FIGS. 3 to 5 show embodiments of link chains according to the invention, in each case in section according to II in FIG. 1, that is to say in a cross section through the link chains 1 shown in the direction of travel L.
- the illustration shows a link chain 1 as well as a toothed wheel 10, with which the Comb teeth 9 of the link chain.
- a single spacer tab 11 is arranged as a spacer element between two tabs 2 and counter-tabs 3.
- Fig. 6 shows the link chain of FIG. 3 in a perspective view.
- the spacer straps 11 are each arranged between two straps 2, wherein the straps packets on both sides of the spacer straps 11 are equally strong, they each comprise three straps 2.
- the spacer strap is thus arranged in a central position.
- guide plates 12 are arranged in the link chains 1 as shown in FIG. Surround around the gear 10 and so in a known manner for guiding the link chain 1 on the gear 9 transverse to the running direction L.
- FIG. 4 shows a further exemplary embodiment of a link chain according to the invention.
- two narrow spacer straps 11 'and 11 are arranged between two straps 2.
- the spacer straps 11' and 11" can be arranged at any point within a chain link, thus a straps package, and instead of two spacer straps, a larger number of spacer straps can be provided
- Fig. 5 shows a third embodiment of a link chain according to the invention, here are each a spacer tab 11 '"and 11""between a tab 2 and a guide plate 12 are arranged.
- the spacer straps 11 can also be arranged between counter-straps 3. It is also possible - especially in the three-lobe composite - to arrange the spacer plates 11 between tabs 2 and 3 counter-lugs.
- FIGS. 7a to 10b show exemplary embodiments of spacer straps 11 in section and in the side view corresponding to the view in FIG. 1.
- the spacer strap 11 essentially corresponds to the cross section of a strap 2 without its teeth 9.
- the spacer strap 11 according to FIG. 7a protrudes thus in particular on the gear 10 in the installation position facing side when combing the teeth 9 of the tabs 2 is not in the toothing of the gear 10 into it. This corresponds to the representation of FIGS. 3 to 5.
- the spacer straps 11 contact the tooth flank upper edges of the toothed wheel 10, this is not shown as a dashed line 13.
- FIG. 7b the spacer plate 11 is shown in FIG. 7a in the installed position in a longitudinal section through the link chain 1 in the direction L.
- the bores 13 are in each case on both rockers 5, 6 and are held in position.
- FIGS. 8a and 8b show an alternative embodiment of a spacer flap 11, here identified by the reference numeral 11a for ease of distinctness.
- a receiving opening 13a is introduced in the manner of a slot, so that the spacer tab is only in each case with the two of the tab 2 with the teeth 9 associated rocking pieces 5 in contact and hold the spacer tab 11a in the direction L in position.
- the spacer flap 11a thus has essentially the shape of a closed ring. Recesses 15 on both sides of the spacer plate 11a create a higher distance to the tooth flank upper edge 14 in all four possible mounting positions within the link chain.
- FIGS. 9a and 9b show a further embodiment of a spacer flap 11b according to the invention.
- an opening 16 is here introduced in each case, which are each provided with an opening 17 on the same side and thus comprise the rocker pieces 5, 6 in the manner of a clip.
- This allows a subsequent mounting of the spacer plates 11b in the link chain 1 by the link chain 1 is first preassembled with tabs 2, counter-tabs 3 and 5 and 5 rocker plates and guide plates, with a distance between individual tabs 2 and 3 opposite tabs.
- the spacer plates 11 b can be retrofitted by these are pressed with the aid of the openings 17 on the rocker 5,6 in the manner of a clip.
- FIGS. 10a and 10b show a further alternative embodiment 11c of a spacer flap.
- the openings 16 and openings 17 correspond to the embodiment according to FIGS. 9a and 9b.
- teeth 18 are arranged on the sides of the spacer straps 11 c opposite the openings 17. These can be designed so that they are in installation position of the link chain 1 in the chain running plane in the view of FIG. 10b, thus transverse to the direction L of the link chain 1, congruent with the teeth 9 of the tabs 2.
- the spacer plate teeth 18 according to FIG. 11 can project beyond the contour of the teeth 9 at least in regions, this being illustrated by arrows 20.
- overhang is meant here that they protrude beyond the tooth flank profile of the teeth 9, so that they protrude when meshing the teeth 9 with the gear 10 in the teeth of the gear 10, so overlap with the tooth flank profile of the gear 10.
- the enveloping contour of the spacer flap 11c in the chain running plane is greater in the region of the teeth of the tabs and / or the counter-tabs than the enveloping contour of the teeth of the tabs and / or the counter-tabs themselves.
