Definitions
- the invention relates to a device and method for improving the corrosion protection in bearing assemblies and equipped with such a corrosion protection device bearing arrangement, for example consisting of 25CrMo4, 42CrMo4, 43CrMo4, 34CrNiMo6, C45, C45N, X20Cr13, GG-20, GGG-40, GS15, St 37 or similar material.
- the corrosion protection device serves to improve the corrosion protection in and on through holes or blind holes in or on bearing arrangements such as rolling bearings and / or slewing rings.
- the invention particularly characterizing are each the characterizing features of the claims, or the advantages mentioned. State of the art and current problem areas:
- Bearing arrangements such as rolling bearings, slewing bearings and slewing rings, but also moment bearings, which are used today in aggressive gas / steam environments and / or in a humid environment, for example, in 'offshore' installed wind turbines or in tunneling machines in the underground or in hydroelectric or underwater power plants, Experience has shown that they are subject to a higher degree of corrosion than rolling bearings, slewing bearings, slewing rings or torque bearings which are permanently exposed to a dry gas environment.
- Corroding machine and equipment parts of such bearing arrangements such as corroding holes or contact surfaces of bearings and slewing bearings, corrosive raceway systems of rotary joints or torque bearings, et cetera, which are not recognized early enough due to a hard to reach location and thus not repaired or repaired , may fail before reaching the calculated life. Greater consequential damage to other or neighboring parts of the system is not uncommon.
- cathodic corrosion protection [2] entails installation and maintenance costs of additionally necessary systems, ie at least one protective current device must be installed and a depth anode must be installed. Apart from that, cathodic corrosion protection is usually provided only for earth or water-related metal structures.
- VCI volatile-corrosion-inhibitor
- VCI or VPCI corrosion inhibitors as a lubricant or as a spray
- Opinions exist that such VCI / VPCI lubricants or VCI / VPCI sprays offer only temporary corrosion protection.
- the problem arises that the penetrating into the bore lubricant or spray applied evenly to the entire surface of the borehole must become. This is difficult in practice, as a VCI / VPCI spray fog-like reflected in the bore and thus only the cloud directly opposite surfaces are detected by the means. For example, the thread flanks in the fog shadow remain unwetted.
- the sprayed or smeared substance evaporates after a relatively short time.
- the use of metallic machine and equipment parts made of stainless steel or semi-precious steel is a valid method to prevent or avoid the negative effects of corrosion, but it is strongly detrimental that stainless steel or semi-precious steel is usually a more expensive material than for example 42CrMo4 or C54N and thus causes some significant additional costs.
- the present invention has the technical problem of eliminating those disadvantages which result from corrosion when bearing assemblies are used in or with metallic machine and equipment parts in aggressive gas / steam environments and / or in a moist environment. It is the technical task to solve a bearing assembly, for example, consisting of a conventional bearing and / or structural steel or the like to create, which has a low corrosion tendency in and on the through holes or blind holes compared to the rest of the bearing assembly and longer lasting, ideally provides much longer-lasting, corrosion protection than previous sprays or smear layers.

- this at least one sleeve is not made of spring steel.
- such sleeves are preferably made of non-metallic material, for example of plastic or foil or cardboard or even of solid paper or of textile material such as felt or fabric.
- the non-metallic sleeve material may be wetted or soaked or filled with a corrosion inhibitor, for example corrosion inhibitors such as VCI or VPCI, alternatively with a grease-based antiperspirant or corrosion inhibitor such as polf fat.
- the aforesaid anticorrosive agent is based on a mixture whose proportion provides highly refined hydrocarbons. It lies Furthermore, in the sense of the technical theory of the invention, that the at least one sleeve is made mid-free. In this case, this sleeve can serve as a corrosion inhibitor carrier material, in particular as a VCI donor or VPCI emitter, which emits VCI molecules or VPCI molecules in the gas phase.
- the at least one sleeve can be made mid-free and impregnated with Polfett or even wetted.
- Polfett can remain sustainable in the sleeve has been found to be particularly advantageous if a special form of such a sleeve has separate undercuts or chambers which are filled with Polfett or at least can be filled with Polfett. This measure ensures that the corrosion-inhibiting effect of the invention is retained for as long as possible.
- the particular advantage of the aforementioned corrosion protection device with at least one sleeve occurs when preferably at least one of the screws (for example, in each case in the design of a Dehnschaftschraube) or even at least one of the rivets is provided with at least one such sleeve.
- this sleeve encloses the screw or the rivet possibly standing even under mechanical stress, since by this measure, an axial slippage of the sleeve on the screw or the rivet can be largely prevented.
- the screw or the rivet is, as known from the storage technology, respectively introduced into a through hole or blind hole of the bearing assembly, wherein the respective associated sleeve meanwhile the screw or the rivet, optionally under mechanical stress, enclosing and thus also into the well, ie in the through hole or blind hole, is introduced.
- the present device is recommended for corrosion protection when using Dehnschaftsschrauben or expansion bolts according to DIN 2510.
- Expansion bolts are namely particularly useful for constructions that are claimed by changing operating forces and changing temperatures, such as apparatus, pipelines, turbines of plants, vibrating plant components, o. ⁇ .
- the abovementioned screws, expansion shank bolts or rivets are generally used to fix a first attachment surface to a first attachment structure, or alternatively to fix a second attachment surface to a second attachment structure.
- moment bearings As a bearing assembly in the context of the present teaching, all types and types of moment bearings, (large) roller bearings and slewing come into question, for example, but not limited to, single-row or multi-row slewing bearings, roller slewing, ball bearings, four-point bearings, combination bearings, needle roller bearings and bearings with conical or barrel-shaped rolling elements, cross roller bearings, wire roller bearings, et cetera.

- this changed structure zone can be introduced by rolling or rolling or other cold clamping in the circular peripheral surface of each hole.
- Such a changed microstructure zone in the borehole of the bearing material has, in the sense of the invention, increased compressive stress energies compared to the base material of the bearing arrangement.
- the method for introducing the corrosion protection in the sense of the changed microstructure zone is carried out according to the invention as follows:
- This aforementioned modified microstructure zone is applied, for example, by means of one or by a pressure jet method.
- small and hard, for example, spherical, body are injected under very high pressure in the borehole.
- the kinetic energy of these small and hard bodies transforms upon impact with the borehole surface to significantly large parts in plastic deformation energy by which the present before this step in the borehole structure is clamped, for example, cold-stressed.
- a surface compression is preferably effected by a ball-pressure jet method and thereby increases the corrosion protection.
- zinc-containing blasting agents can be used.
- the zinc in such a blasting agent brings the significant improvement that the irradiated surface, so usually the surface in the borehole (blind hole or through hole) is galvanized, which is conducive to additional protection against corrosion.
- the bearing arrangement equipped therewith is further developed in such a way that a corrosion-inhibiting or corrosion-inhibiting powder is introduced or introduced into at least one borehole of the bearing rings, for example a powder which emits VCI molecules or VPCI molecules in the gas phase.
