Definitions

  • the invention relates to a sliding washer made of sheet steel for the arrangement between see an inner ring and an outer ring of a sprag clutch with a radially extending portion and at its inner edge and outer edge adjoining axial sections, each having an inner surface and an outer surface. Furthermore, the invention relates to a method for producing the sliding disk and the use of different types of steel for the sliding disk.
  • a sliding disk of the type mentioned above is known for example from DE 10 2005 046 799 A1.
  • This sliding disk has a nickel-phosphor coating, whereby very good wear properties are achieved, which is given because of the use of steel as the base material of the sliding disk, the same coefficient of expansion as for the other steel components of the sprag free-wheel clutch.
  • This nickel-phosphorus coating has proven itself, but is expensive to manufacture, albeit less expensive than the production of sliding plates made of a copper alloy, which is described for example in DE 299 04 524 U1.
  • the invention is therefore the object of a sliding washer for a freewheel clutch, which is operated under changing conditions, in particular fluctuating temperatures, in terms of manufacturing costs to improve.
  • At least the outer surfaces of the axial section of the sliding disk adjoining the inner edge and outer edge of the radially extending section are provided with a nitrogen and carbon-enriched, wear-resistant and corrosion-resistant edge layer produced by nitrocarburizing.
  • Nitrocarburizing is a thermochemical process for enriching the surface layer of a workpiece with nitrogen and carbon. This results in a nitriding layer, consisting of bonding layer and diffusion layer.
  • the enrichment of the surface layer of a workpiece with nitrogen and carbon can be carried out by means of gas-nitrucarburizing, salt bath-nitrocarburizing or plasma-nitrocarburizing.
  • the gas nitrocarburizing is carried out at temperatures between 500 ° C and 600 ° C in a gas mixture which can deliver nitrogen (eg ammonia) and carbon (eg carbon dioxide). The aim is to improve the wear resistance and corrosion resistance of low to medium alloy steels.
  • salt bath nitrocarburizing components made from low to medium alloy steels and cast iron are treated in a molten salt bath at temperatures of 550 ° C to 630 ° C. Advantages of the method are the short treatment time and the high wear resistance and corrosion resistance produced. As Salzbadkomponenten serve Alkalicyanate and alkali carbonates, the spent salts can be post-dosed during the reaction. By means of the Plasma nitrocarburizing also allows hardening of highly alloyed steels in the surface layer. The components are treated at temperatures of 350 ° C to 600 ° C with ionized gas. As a rule, no mechanical aftertreatment of the parts is required.
  • the sliding washer according to the invention of nitrocarburized steel sheet is cheaper to produce than a sliding disk made of bronze-plated steel sheet, nickel-phosphorus-coated steel sheet or solid bronze.
  • the edge layer consisting of a connecting layer and a diffusion layer preferably has a thickness of approx. 10 ⁇ m, through which a wear-resistant composite layer having a hardness of at least 400 HV and a mass fraction of approx. 1% carbon and approx. 15% nitrogen. Since the nitrocarburizing is carried out at a temperature of preferably 550 ° C, the delay of the sliding disk is minimal.
  • the high nitrogen content ensures very good wear and friction properties, as has been shown by vibration friction wear tests on samples of the sliding disks made of different materials.
  • the nitrocarburized samples of the steel grades C16M or 16MnCr5 have hardly any wear in comparison to sliding disks made of brass or bronze.
  • the running behavior is constant without tarnish or galling sensation.
  • the sliding disks generally have slightly conical outer surfaces after production of the axial sections adjoining the radially extending section. Idle wear tests on such sliding disks show that the conicity can cause a lubricant film interruption. In this case, a mixed friction state prevails in the load zone, which leads to the temperature rise and to an increase in wear. Since the oil in freewheel is thrown radially outward on contact with a rotating sliding disk, the sliding disk can run dry in the load zone, whereby a further increase in temperature and an increase in wear occur.
  • At least the outer surface of the axial section adjoining the inner edge of the radial section is provided with a plurality of preferably uniformly spaced, axially extending oil grooves, the number of oil grooves resulting from the fact that in a zone of the sliding plate with minimal load at least three oil grooves are present.
  • This means that nine oil grooves for sliding disks with a diameter suitable for conventional sprag-type one-way clutches are generally sufficient, whereby the surface pressure in the remaining areas of the sliding disk does not increase significantly.
  • the width of the oil grooves can be about 3 mm and the depth of about 0.6 mm, whereby a sufficient oil supply to the contact surface in the load zone and a hydrodynamic lubricating film structure are ensured. This oil also causes sufficient cooling of the highly stressed inner race of the sliding disk.
  • the preparation of the lubrication grooves can be integrated in a simple manner and cost neutral by forming associated webs in the thermoforming tool, which is minimized by a circular segment-shaped cross section of the oil grooves of the wear of the thermoforming tool.
  • the sliding disk with the features listed above can advantageously be produced by deep-drawing means of a deep-drawing tool from a sheet steel blank, after which the nitrocarburizing is subsequently carried out.
  • the oil grooves can be during deep drawing by the deep drawing tool in the outer surface of the adjoin the inner edge of the radial portion, axial section, whereby the tool cost, although slightly increase, but not the Herstell cost.
  • the nitrocarburizing of the sliding disk can also be combined with carbonitriding, which further improves the wear and friction properties become.
  • Carbonitriding is also one of the thermochemical processes that enriches the surface layer of components with carbon and nitrogen and improves the mechanical properties of the component edge layer.
  • the carbonitriding curing temperatures are generally between 760 ° C and 900 ° C, i. higher than the Nitrocarbuheren.
  • the effect of carbonitriding is based on carbon diffusion and nitrogen diffusion at the same time. By enrichment of nitrogen, the hardening temperature and the critical cooling rate are lowered, so that it can be quenched milder. Both factors reduce the risk of default.
  • Subsequent tempering treatment sets the desired surface hardness. For carbonitriding, unalloyed and low-alloyed case-hardened steels as well as free-cutting steels and structural steels are suitable. These are generally steels with carbon contents below 0.2%. Carbonitriding serves to give the surface layer of steel workpieces and tools a much higher hardness and better mechanical properties to the workpieces or tools. Carbonitriding results in increased wear resistance with simultaneous low distortion.
