Definitions
- the invention relates to a component with a component body having a toothing, and an assembly comprising at least two components, each having a toothing, wherein the at least two toothings is in meshing engagement with each other.
- the quality of the toothing of gears is usually classified according to DIN 3963 in 12 quality levels, where 1 denotes the finest and 12 the coarsest gear quality.
- the division is made according to the manufacturing process, with the toothing honed by quality 1-6 gears, those of quality 2-7 ground, those of quality 5-7 scraped, those of quality 5-9, milled, roller planed or rolled, those of quality 7 -12 is milled or formed, and that of quality 8-12 is stamped, pressed, sintered or sprayed, and combinations of the machining processes are also carried out.
- a high gear quality of a gear can be achieved only by intensive processing, resulting in higher production costs.
- the adaptive coating By arranging the adaptive coating in the specified minimum layer thickness, it is achieved that, by mainly plastic deformation of the coating, the support part of the toothing, that is, the proportion of the bearing surface during the meshing engagement in a toothing of another component, is increased, whereby the surface load is reduced.
- the deformation of the coating whereby material is brought into the valleys between these peaks by the roughness peaks (normally the unevenness of the substrate is reshaped during the deposition of the coating), a hardening of the coating can occur as well, which likewise increases the mechanical strength of the component. ie the teeth of the component, can be achieved.
- this deformation results in a partial leveling of the surface roughness.
- a toothing with a quality of 10 through this coating reaches a quality of 8 to 6, in particular with regard to the concentricity error or the standard modulus range.
- the macrogeometry of the surface of the toothing is significantly improved by the arrangement of the adaptive coating in the stated minimum layer thickness.
- the components themselves can therefore be manufactured using a more cost-effective method, and no further expensive hard finishing operations are required by depositing the adaptive coating on the toothing in order to achieve the higher gear quality.
- the adaptive coating has the advantage that it only wears down wear on extremely stressed areas of the toothing during operation, so that the "leveling effect" is maintained over a long operating life of the component
- the minimum layer thickness of the adaptive coating is adapted to the respective quality, ie to the surface roughnesses present, with different qualities of toothing, after the surface roughness of the toothing has also been transferred to the coating during the coating - Will carry - it is preferred at least approximately at each coated point, the same layer thickness produced - should the later, generated by deformation of the adaptive coating support layer above the highest roughness peak of the toothing verlau fen.
- the toothing of the component can be pre-calibrated, for example by rolling.
- the layer thickness of the adaptive coating is selected from a range with a lower limit of 5 ⁇ and an upper limit of 100 ⁇ , in particular from a range with a lower limit of 12 ⁇ and an upper limit of 30 ⁇ .
- a component with a higher quality of the toothing since these teeth can act as "embossing" for the adaptive coating, and thus the quality of the teeth of the assembly can be improved overall.
- the adaptive coating has a hardness gradient with increasing hardness from an outer coating surface in the direction of the component body. It is thus achieved that the adaptive coating on the outer coating surface, which meshes with another toothing of another component in the installed state of the component, can be made relatively soft, so that the deformation, i. Flattening of the profile peaks of the roughness profile can be done quickly, and also by the greater hardness at the interface to the component body better adhesion of the coating is achieved at this. In addition, a higher strength of the coating can thus be made available in layers below the coating surface, so that their mechanical strength in the
- Operation can be improved. Due to the greater hardness at the interface to the component body, a higher fatigue strength is achieved.
- the adaptive coating on the outer coating surface preferably has a hardness which is selected from a range with a lower limit of HV 40 and an upper limit of HV 500, in particular from a range with a lower limit of HV 200 and an upper limit of HV 300, or according to a further preferred embodiment, on the second, facing the outer coating surface, in the direction of the component body facing surface has a hardness which is selected from a range with a lower limit of HV 500 and a upper limit of HV 2000, in particular from a range with a lower limit of HV 800 and an upper limit of HV 1200. (Microhardness according to Martens, test load 10 mN, see below) It is possible that the adaptive coating is composed of several different partial layers.
- this embodiment can simplify the manufacture of the adaptive coating because successive layers of different Composition can be deposited on the component body, which can reduce the control or control effort during the coating.
- the adaptive coating is at least partially metallic. Compared to polymer layers, a longer service life of the adaptive coating is achieved. In addition, a greater variability in the coating composition can be achieved because only a few polymers are suitable for the intended use of the component. It can therefore be taken better account of different load cases of the component by the at least partially metallic version of the adaptive coating, so that the invention can be applied in a wider field. It is also advantageous that the adaptive coating thus has a better heat conductivity, so that undesired phase changes in the coating can be better avoided, and thus the coating has at least approximately the original phase composition over a longer period of time, so that its behavior during operation over a longer period is at least approximately the same.
- adaptive coatings are particularly suitable if they are formed by a multicomponent system, where at least one component is selected from a group comprising transition metals, transition metal nitrides, transition metal carbides, transition metal oxides and mixtures thereof, wherein, according to an Au variant variant to another component of the multicomponent system is selected from a group comprising or consisting of Sn, Mg, Al, In, Bi, Si, Ni, Ag, Cr and Fe.
- the adaptive coating contains the components Ag and Cr or CrN, wherein the content of Ag decreases from the outer coating surface toward the component body, or the components Cu, CuSn and Cr, wherein the content of CuSn from the outer coating surface toward decreases the component body, or the components Ag and Ti, wherein the content of Ag from the outer coating surface in the direction of the component body ab- takes.
- adaptive coatings have been found to be advantageous, which are formed from a copper bronze or an aluminum bronze, optionally containing at least one of the components chromium nitride, Fe, Cr, Ni, Ag.
- the nitrides it should be mentioned that, according to one embodiment variant, these are present only in transition zones, but otherwise the coating only has metallic components.
- systems with a miscibility gap in the solid state or immiscible systems are used.
- components or metals with a cubic area-centered lattice are used, since these are particularly well suited with regard to plastic deformability.
- the adaptive coating is at least approximately or completely free of abrasive particles, that is of particles which would cause abrasion on the toothing of another component of the assembly in meshing engagement with the toothing of the component , So it is thus the increase in quality mainly by forming work on the adaptive coating itself and not achieved by targeted material removal in the range of meshing teeth, so that the other component, so for example, the above-described component with the "embossing" remains at least largely undamaged.
- the amount of dirt introduced into a lubricating oil intended for lubricating the toothing is reduced so that it can be used for a longer period of time - Be executed treatment surface harder, since no provision must be made for the embedding of these dirt particles in soft matrix components of the coating, which in turn can be improved, the capacity of the adaptive coating.
- an adhesion promoter layer can be arranged between the adaptive coating and the component body.
- the pores in the adaptive layer preferably have a diameter of at most 3 ⁇ m, in particular a maximum of 0.3 ⁇ m.
- the coating does not have any pores in the classical sense, but there are open “channels” or regions at the grain boundaries of the coating, thus also allowing the ingestion of liquids such as lubricating oils.
- the porosity decreases from the outer coating surface in the direction of the component body.
- a gradient of porosity is formed in the adaptive coating.
