Definitions

• the present invention relates to a chain, in particular a conveyor chain for the transport of body carriers or general cargo, according to the preamble of claim 1.
• a chain of the aforementioned type is known for example from EP 1 645 528 A1.
• the chain described therein is a roller carrying chain that can be used to convey objects.
• the chain has bushings arranged on the bolt, on which in turn the rollers are mounted.
• the outer flaps and the inner flaps like the bolts, bushings and rollers, are made of metal. If heavy objects such as skids are to be transported in the automotive industry with such a chain, the chain and / or the body wear a large amount of wear.
• sliding strips must be arranged on the outer sides of the chains in order to reduce the friction of the chains in sliding channels.
• the bolts and / or the bushes are usually pressed into the outer and / or inner plates, so that an assembly or disassembly of individual tabs is associated with considerable effort.
• the problem underlying the present invention is the provision of a chain of the type mentioned, which is subject to less wear and / or constructed simpler and / or less expensive.
• the outer flaps and / or the inner flaps are movably arranged on the bolt and that the chain comprises a lock ring which can be applied to the bolt so that the outer flanges and / or the inner flanges can be easily assembled and / or disassembled.
• the chain comprises a plurality of rollers which project beyond the outer straps and / or the inner straps at least on one side, that the chain comprises no bushings, in particular no joint bushings, and that the rollers are arranged on each or some of the bolts ,
• the outer plates and / or the inner plates are made in particular of plastic or even of metal, such as steel.
• the outer straps and / or the inner straps are formed cranked, in particular so that outer straps and inner straps can be made the same.
• slide bearings are arranged on the inside of the rollers, in particular metallic or non-metallic, preferably made of plastic plain bearings, or at least one needle sleeve or at least one ball bearing. As a result, the rotation of the rollers is ensured even when not provided socket.
• the chain is formed lubricious and / or maintenance-free. This too can be achieved by corresponding properties of the plastic of the outer straps and / or the inner straps.
• Fig. 1 is a side view of a chain according to the invention
• Fig. 2 is a plan view of the chain of FIG. 1;
• FIG. 3 is a front elevational view of the chain of FIG. 1;
• Fig. 4 is a partially cut-away perspective view of the chain of Fig. 1;
• Fig. 5 is a perspective view of a bolt of the chain of FIG. 1;
• Fig. 6 is a front perspective view of an outer link of the chain of Fig. 1;
• FIG. 7 is a rear perspective view of the outer flap of FIG. 6; FIG.
• FIG. 8 is a front perspective view of an inner link of the chain of FIG. 1;
• FIG. 9 is a rear perspective view of the inner flap of FIG .. 8
• FIGS. 1 to 4 The embodiment of a chain according to the invention which can be seen from FIGS. 1 to 4 comprises outer straps 1, inner straps 2, bolts 3 projecting through two outer straps 1 and two inner straps 2 (see FIG. 3) and onto the bolt 3
• the rollers 4 project beyond the outer straps 1 and the inner straps 2 in the position of use (see in particular FIGS. 1 and 3).
• outer straps 1 with inner straps 2 alternate on each side of the chain.
• a bolt 3 connects on each of the two sides of the chain an outer flap 1 with an inner flap 2.
• each of the bolts 3 for example, in Fig. 3 left side of the chain with the right in Fig. 3 side of the chain.
• the outer plates 1 and the inner plates 2 may in particular be made of plastic.
• Polyoxymethylene (POM) or polyethylene terephthalate (PET) have proven to be plastics with particularly favorable properties in terms of high wear resistance and good sliding properties. However, it is also possible to use other plastics.
• POM Polyoxymethylene
• PET polyethylene terephthalate
• the use of at least partially made of metal outer plates 1 and inner plates 2 is possible.
• the outer flaps 1 and the inner flaps 2 are formed cranked, so that the connecting openings 9, 10, 1 1, 12 surrounding the passage openings 5, 6, 7, 8 spring back relative to the middle sections 13, 14 of the outer flaps 1 and inner flaps 2.
• the outer plates 1 and inner plates 2 in the interconnected state in the transverse direction occupy a comparatively small space, because they partly engage with one another.
• the outer flaps 1 are shaped differently than the inner flaps 2.
• Both the outer plates 1, and the inner plates 2 have a plurality of holes 15, which serve to reduce weight.
• the passage openings 5, 6, 7, 8 are eccentrically arranged with respect to the vertical direction in the use of the outer plates 1 and the inner plates 2, so that the arranged on the bolt 3 rollers 4 down, but not above the outer plates 1 and protrude the inner plates 2 (see Fig. 1 and Fig. 3).
• the apparent from Fig. 3 bolt 3 may be made of metal, such as steel, but also made of plastic.
• the bolt 3 has a central portion 16 and two adjoining outer portions 17.
• the middle section 16 has a larger outer diameter than the outer sections 17.
• the outer portions 17 extend in the assembled state of the chain through the passage openings 5, 6, 7, 8 of the outer plates 1 and the inner plates 2 therethrough.
• the inner diameter of the passage openings 5, 6, 7, 8 is slightly larger than the outer diameter of the outer portions 17, so that the outer plates 1 and the inner plates 2 are loosely arranged on the outer portions 17 of the bolt 3.
• a circumferential groove 18 is arranged (see Fig. 5), in which a locking ring 19 can be introduced to hold the outer plates 1 and the inner plates 2 on the bolt 3 (see FIG 1 and 4).
• the roller 4 may be made of metal, such as steel, but also made of plastic.
• a sliding bearing 20 is arranged (see Fig. 4) that may be formed as a metallic or non-metallic, preferably made of plastic plain bearing.
• a needle sleeve or a ball bearing can be provided on the inside of the roller 4.
• the rollers 4 are mounted on the sliding bearing 20 directly on the bolt 3.
• the outer diameter of the central portion 16 of the bolt 3 may be equal to the outer diameters of the outer portions 17.
