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 3963in 12 quality grades, with 1 designating the finest and 12 the coarsest tooth 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 milled or formed, and those of quality 8-12 are stamped, pressed, sintered or sprayed, whereby 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 unevenness or roughness of the surface and deviations in shape on a microscale up to 10 ⁇ understood.
- This object is achieved on the one hand by the aforementioned component and on the other hand by the assembly, wherein on the toothing of the component at least partially an adaptive coating is applied, which has a layer thickness of at most 5 ⁇ , and wherein at least one of the components of the assembly is formed according to the invention ,
- the adaptive coating in the specified maximum layer thickness is achieved that by plastic deformation of the coating of the supporting portion of the tooth, ie 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 the roughness tip material is brought into the valleys between these peaks (when depositing the coating, the unevenness of the substrate is usually reformed) can also solidify the coating, thereby also increasing the mechanical strength of the component , ie the toothing of the component, can be achieved.
- this deformation achieves an at least partial leveling of the surface roughness.
- the quality of the toothing is improved by the coating by at least one quality level, for example, achieved a toothing with a quality of 8 by this coating a quality of 7 to 6.
- the microgeometry of the surface of the toothing is significantly improved by the arrangement of the adaptive coating in the specified maximum 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 time of the component
- the maximum layer thickness of the adaptive coating is adapted to the respective quality, ie to the surface roughnesses present, with different qualities of toothing Coating is transferred - the same layer thickness is preferably produced at least approximately at each coated point - should the later layer be produced by deformation of the adaptive coating. begotten support layer run above the highest roughness peak of the toothing. Thanks to the adaptive coating, an improvement in the so-called pitting could be achieved by reducing the heart's pressure.
- 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 1 ⁇ and an upper limit of 4 ⁇ .
- the assembly is preferably used as a second component with a toothing, which meshes with the toothing of the component according to the invention, 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 gearing of the assembly as a whole can be improved.
- 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 or better fatigue strength. In addition, a higher strength of the coating can thus be made available in layers lying below the coating surface, so that their mechanical load capacity during operation can be improved.
- 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 1000, in particular from a range with a lower limit of HV 100 and an upper limit of HV 300, or according to another preferred embodiment on the second, the outer Coating surface opposite, pointing in the direction of the component body surface hardness selected from a range with a lower limit of HV 400 and an upper limit of HV 1600, in particular from a range with a lower limit of HV 650 and an upper limit from HV 1000.
- the adaptive coating is composed of several different partial layers. Although this is not the preferred embodiment of the invention, since there is preferably a continuous transition of the properties from the outer coating surface toward the component body, 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 thermal conductivity, so that unwanted phase changes in the coating can be better avoided, and thus the coating over a longer period of time at least approximately the original phase composition, so their behavior during operation over a longer period at least approximately constant.
- 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 embodiment, another component of the multicomponent system is selected from a group comprising Sn, Mg, Al, In, Bi, Si, Ni, Ag, Cr and Fe.
- the adaptive coating contains the components nents Ag and Cr or CrN or the components Ag, Sn and Cr or CrN, wherein the content of Ag decreases from the outer coating surface toward the component body, or the components Sn and Cr or the components Cu and Cr and optionally Sn, wherein the content of Sn decreases from the outer coating surface toward the component body, or the components Ag and Ti and optionally Sn, wherein the content of Ag decreases from the outer coating surface toward the component body.
- adaptive coatings have been found to be advantageous, which are formed from a tin bronze or an aluminum bronze, wherein optionally at least one of the components chromium nitride, Fe, Cr, Ni, Ag is included.
- the adaptive coating may also include the components Ag and Cr, or Ag and Sn and Cr, or Cu and Cr, or Cu and Sn and Cr, or Cu and Al and Fe and Cr, or Ag and Ti, or Ag and Sn and Ti include, without the above condition, that the proportion of at least one component within the coating is varied.
- 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.
- 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 2 ⁇ m, in particular a maximum of 0.5 ⁇ m.
- the porosity decreases from the outer coating surface in the direction of the component body.
