  Embodiments of the present invention will be described below with reference to the accompanying drawings.

  FIG. 1 exemplarily shows a side view of a link plate chain according to the state of the art with a two link plate complex, ie a repeating unit consisting of two link plates. A plan view of the link plate complex is shown. The basic structure of the link plate chain and the concept used in the embodiment according to the present invention will be described with reference to FIGS. The embodiments are described by way of example of a link plate chain comprising a two-link plate complex, but can also be applied to a three-link plate complex (Dreilaschembaband), ie a link plate chain comprising a repeating unit consisting of three link plates. It is. The link plate chain 1 has a large number of link plates 2 and corresponding link plates 3. The link plates 2 and the corresponding link plates 3 are alternately arranged, and are connected as joints by joint pins 4. Therefore, both ends of one link plate are coupled to one or two corresponding link plates by one joint. Correspondingly, both ends of one corresponding link plate are connected to one or two link plates by one joint. The joint pin 4 may be a one-piece, but is preferably a two-piece, in which case one rocker pin 5 is arranged corresponding to each link plate and another rocker arranged corresponding to the corresponding link plate 2. Roll on pin 6. For this purpose, the rocker pins 5, 6 each have one rolling profile 7 or 7 '. By this rolling profile 7 or 7 ', the rocker pins 5, 6 can roll or slide relative to each other. The rolling profiles 7, 7 'can be the same or different. The link plate 2 and the corresponding link plate 3 are stacked in the lateral direction with respect to the traveling direction L (indicated by a double-pointed arrow in FIGS. 1 and 2). As a result, between the two joint pins 4 arranged side by side in the lateral direction with respect to the traveling direction L, one corresponding link plate arranged in an overlapping manner is arranged. On the contrary, one link plate is arranged between the two corresponding link plates positioned side by side in the lateral direction with respect to the traveling direction L. Of course, this does not apply to the link plate 2 or the corresponding link plate 3 arranged outwardly in the lateral direction with respect to the traveling direction L, respectively. They have an adjacent plate on only one side. Each of the link plate stacks thus formed in the link plate 2 forms one chain link 8 in a stack. Correspondingly, the (corresponding) link plate stack of the corresponding link plate 3 forms one chain link 8 'in a stack. The link plate 2 and the corresponding link plate 3 may be the same component in this embodiment, and the difference between the link plate 2 and the corresponding link plate 3 can be identified only by arrangement. FIG. 2 shows a laminate composed of three link plates 2 and two corresponding link plates 3. Here, it is also possible to provide a laminate comprising any other number of link plates 2 and corresponding link plates 3.

  Each link plate 2 is provided with teeth 9 as can be seen in FIG. With these teeth 9, the link plate chain 1 can mesh with a tooth row, for example a gear tooth row. At that time, the pitch between the link plate 2 and the corresponding link plate 3 is generally designed so that a uniform pitch is generated between the link plate teeth 9 when the chain is extended. As an alternative, since the teeth 9 can be provided on the corresponding link plate 3, the teeth 9 are provided on all the link plates and the corresponding link plates, respectively. However, it is also possible to provide only one tooth 9 for each link plate and corresponding link plate.

  3 to 5 show an embodiment of the link plate chain according to the present invention in a sectional view based on the line segment I-I in FIG. Has been. One link plate chain 1 and a gear 10 are shown, respectively, and the gear 10 and the teeth 9 of the link plate chain mesh. In FIG. 1, one individual space link plate 11, which is a space element, is arranged between two link plates 2 or corresponding link plates 3. FIG. 6 shows a perspective view of the link plate chain according to FIG. As can be seen, the space link plates 11 are each disposed between the two link plates 2. In this case, the link plate stack has the same stack thickness on both sides of the space link plate 11, and each has three link plates 2. Therefore, the space link plate is disposed at the center position. When viewed in the traveling direction, guide link plates 12 are arranged on both sides of the link plate stack in the link plate chain 1 of FIGS. These guide link plates 12 surround the gear 10 and are thus provided in the known manner for guiding the link plate chain 1 in the gear 9 in a direction transverse to the running direction L.

  FIG. 4 shows another embodiment of a link plate chain according to the present invention. Here, two narrow space link plates 11 ′ and 11 ″ are arranged between the two link plates 2. These space link plates 11 ′, 11 ″ can be arranged at any position inside one chain link, that is, one link plate stack, and more space links can be used instead of two space link plates. A plate can also be provided.

  FIG. 5 shows a third embodiment of a link plate chain according to the invention. Here, one link plate 11 ′, 11 ″ is arranged between one link plate 2 and one guide link plate 12, respectively.

  Instead of being arranged between the link plates 2, the space link plate 11 can also be arranged between the corresponding link plates 3. Similarly, it is also possible to arrange the space link plate 11 between the link plate 2 and the corresponding link plate 3, particularly in the case of a three-link plate complex.

  7a to 10b show an embodiment of the space link plate 11 in a sectional view or a side view corresponding to FIG. The space link plate 11 corresponds to a side view of one link plate 2 substantially not provided with the teeth 9. Therefore, in particular, the space link plate 11 according to FIG. 7a does not enter the tooth row of the gear 10 on the side closer to the gear 10 in the assembled position when the teeth 9 of the link plate 2 are engaged. This corresponds to FIGS. As can be seen from FIGS. 3 to 5, the space link plate 11 is not in contact with the upper flank edge of the gear 10, which is shown as a dashed line 13. In FIG. 7 b, the space link plate 11 of FIG. 7 a is shown in the assembled position in the longitudinal sectional view of the link plate chain 1 in the traveling direction L. The holes 13 are in contact with the two rocker pins 5, 6 respectively and are therefore held in that position.

  An alternative embodiment of the space link plate 11 is shown in FIGS. 8a and 8b. The space link plate 11 is denoted by reference numeral 11a so that it can be easily distinguished. Instead of the two holes 13, an accommodation opening 13 a in the form of a long hole is provided here. As a result, the space link plate is in contact with only the two rocker pins 5 arranged corresponding to the link plate 2 having the teeth 9, and the space link plate 11a is held in the traveling direction L at that position. Thus, in the cross section of FIG. 8a, the space link plate 11a has a substantially closed ring shape. The recesses 15 on both sides of the space link plate 11a provide a relatively large spacing for the upper flank edge 14 in all four possible mounting positions inside the link plate chain.

  Figures 9a and 9b show another embodiment of a space link plate 11b according to the present invention. Instead of one hole 13, here one opening 16 is provided. The openings 16 are each provided with one through part 17 towards the same side and thus surround the rocker pins 5, 6 in the form of clips. This means that the link plate chain 1 is first assembled to the link plate 2, the corresponding link plate 3, the rocker pins 5, 6 and the guide link plate 12, and the space link plate is assembled to the link plate chain 1 later. to enable. In this case, a predetermined interval remains between the individual link plates 2 or the corresponding link plates 3. After the assembly of the link plate chain 1, the space link plate 11 b can be assembled later, and the space link plate 11 b is pressed against the rocker pins 5 and 6 in a clip form by the through portion 17.

  FIGS. 10a and 10b show another alternative embodiment 11c of a single space link plate. The openings 16 and the penetrations 17 correspond to the embodiment of FIGS. 9a and 9b. In the embodiment of FIGS. 10 a and 10 b, teeth 18 are arranged on the side of the space link plate 11 c facing the through portion 17. These teeth 18 are completely aligned with the teeth 9 of the link plate 2 when viewed in the chain travel plane of FIG. 10b, ie, transverse to the travel direction L of the link plate chain 1 at the position where the link plate chain 1 is assembled. I'm doing it. Alternatively, the space link plate teeth 18 of FIG. 11 can at least partially project the outline of the teeth 9, which is indicated here by the arrow 20. Here, the space link plate tooth 18 protrudes beyond the tooth surface profile of the tooth 9 so that the space link plate tooth 18 contacts the tooth of the gear 10 when the gear 10 and the tooth 9 are engaged. It is understood that it enters, that is, overlaps the tooth profile of the gear 10. The envelope contour of the space link plate 11c in the chain travel plane is dimensioned larger than the tooth envelope contour of the link plate and / or the corresponding link plate itself in the tooth region of the link plate and / or the corresponding link plate. This results in the protrusion 20 of the space link plate teeth 18 being elastically deformed when the gear 10 and the link plate chain 1 are engaged with each other. Bring.
