Definitions

  • the invention relates to a monorail consisting of profiled rails and self-propelled driving means, the profiled rails having horizontal running surfaces for driven rollers and the driving means further comprising guide rollers and / or hold-down rollers.
  • Such monorails are used, for example, in factory systems for conveying components or assemblies of various designs to be assembled. In this way, the load can be attached to the vehicle or placed on the vehicle.
  • the horizontal tread for the roller can be formed on the upper or lower flange of the profile rail and the guide and hold-down rollers can be available in different numbers and arrangements.
  • the profile rails can also be made of aluminum or steel and have different cross-sections.
  • All of these monorail systems have in common that a roller transmits the peripheral force from the driven roller to the profile rail.
  • the circumferential force is particularly great when accelerating, braking and negotiating gradients and would cause the roller to spin when subjected to the high accelerations and decelerations required in modern systems and when negotiating gradients, which are also common in factory systems.
  • acceleration and deceleration are limited and inclines cannot be implemented at all without special design measures.
  • the metal covering applied in this way brings about a reliable increase in the coefficient of friction, which is also only slightly affected by lubricants, with little wear on the roller covering.
  • the explanation for this is likely to be the special surface structure that occurs during cold spraying due to the superficial melting of the sprayed particles. It has strong bumps, but still no sharp edges and should also form channels through which small amounts of lubricant are pressed away.
  • the layer itself is subject to very little wear due to its hardness and is sufficiently firmly connected to the rail surface by the method of application.
  • Cold spraying also has the advantage that the heat input to the profile rail is so low that no distortions, shrinkage or undesirable structural changes can occur and that those used for spraying on Spraying machines are mobile and therefore reworking should they be necessary can be carried out on the spot. Finally, the costs are low because no special materials are required and cold spraying is a quick and easy process.
  • a particularly suitable surface structure is formed when flame spraying or arc spraying with a metal wire is used as the starting material as the cold spraying method.
  • the surface structure of the applied metal covering then shows particularly deep fissures, but which are still not sharp-edged. Alloy steel has proven to be particularly advantageous and inexpensive as a material for the metal covering.
  • the metal covering consists of an adhesive layer and a wear layer, which is particularly important for profile rails made of (e.g. extruded) aluminum.
  • a layer thickness of 0.3 to 0.6 mm has proven to be optimal in terms of effect and cost. However, this can also be greatly increased, for example in order to increase the profile rail in the case of particularly steep or even vertical climbing sections in such a way that the contact pressure also increases.
  • Fig. 1 shows an example of a monorail with driving equipment, in which the subject invention is applicable.
  • the profile rail (1) consists of an upper flange (2), a lower flange (3) and a web (4).
  • a driving device (5) is formed by a chassis (6) which carries a roller (7), pressure roller (9) and a number of guide rollers (10) driven by the motor (8).
  • the roller (7) rolls on the horizontal running surface (11) of the upper flange (2).
  • the roller (7 ') rolls on the tread (11') of the lower flange (3).
  • the pressure rollers (9) are used to hold down the driving equipment and to absorb tilting moments when accelerating. You can be rigid or connected to the chassis (6) via a compression spring, not shown.
  • Guide rollers (10) stabilize and guide the driving equipment.
  • the roller (7) has a bandage (12) made of a plastic of certain hardness, for example polyurethane, to dampen vibrations.
  • a circumferential force is transmitted to the running surface (11) by friction via this bandage (12).
  • a metal covering (15) is applied to this tread (11) (FIG. 2) by cold spraying.
  • Cold spraying is understood to mean surface application processes in which the material to be applied (ceramics, carbides, metals etc.) is melted by means of a fuel gas oxygen flame or with a light or plasma arc and, usually supported by an atomizing gas, is thrown onto the surface to be coated.
  • the material to be applied ceramics, carbides, metals etc.
  • a fuel gas oxygen flame or with a light or plasma arc is melted by means of a fuel gas oxygen flame or with a light or plasma arc and, usually supported by an atomizing gas, is thrown onto the surface to be coated.
  • atomizing gas atomizing gas
  • the metal covering (15) consists of an adhesive layer (13) which contains 80% nickel and 20% aluminum and a wear layer which is a chromium steel of the composition 0.35% C, 0.35% Mn, 0.5 % Ni, 13% Cr, rest Fe.
  • This wear layer is tough and has a particularly favorable surface structure.
  • Fig. 3 is a modification of the invention, which differs from the embodiment of Fig. 2 by the much greater thickness of the wear layer (14). It is so thick that the roller (7) and the pressure rollers (9) are pressed apart, which results in an increased contact pressure. Such a thick wear layer can only be applied with a cold spray process due to the fact that it does not shrink.
  • the variant of FIG. 4 differs from the previous ones only by the cambered upper edge of the wear layer (14), which enables the oil film to be pushed aside in the case of heavily oil-contaminated rails.
