Machine assembly, in particular a tidal power plant
A machine assembly includes a first machine component and a second machine component, the first machine component including a first installation surface and the second machine component including a second installation surface. The first and second installation surfaces are mounted against one another in the assembly. A friction-increasing element is provided in the assembly between the first installation surface and the second installation surface. Further, in the assembled state, a sealing material is introduced into an intermediate space between the first and second installation surfaces.
1. A machine assembly comprising:
a first machine component including a first installation surface;
a second machine component including a second installation surface mounted against the first installation surface;
a friction-increasing element provided between the first installation surface and the second installation surface; and
a sealing material introduced into an intermediate space between the first installation surface and the second installation surface and circumferentially about an entire perimeter of the first and second machine components and the friction-increasing element, the sealing material being formed as a liquid seal composition applied as a liquid to at least one of the first and second installation surfaces and/or the friction-increasing element and cured after assembly of the first and second machine components such that the liquid sealing material bonds to both installation surfaces and flows into any seal gaps in the assembly prior to curing.
2. The machine assembly according to claim 1 , wherein the sealing material is disposed such that the friction-increasing element located between the first installation surface and the second installation surface is protected by the sealing material from an external environment of the machine assembly.
3. The machine assembly according to claim 1 , wherein the friction-increasing element is a friction disc disposed between the first machine component and the second machine component, the friction disc being loose or attached.
4. The machine assembly according to claim 1 , wherein the friction-increasing element is a friction lacquer or a friction coating, the lacquer or coating being applied to the first installation surface and/or the second installation surface.
5. The machine assembly according to claim 1 , wherein the friction-increasing element includes hard material particles.
6. The machine assembly according to claim 5 wherein the hard material particles include at least one of diamond, titanium boride, tungsten carbide and silicon carbide.
7. The machine assembly according to claim 5 , wherein the hard material particles are applied to the friction disc, to the first installation surface and/or to the second installation surface by a corrosion-protecting coating.
8. The machine assembly as recited in claim 7 wherein the corrosion-protecting coating is a nickel coating.
9. The machine assembly according to claim 1 , wherein the machine assembly is a tidal power plant or a current power plant that is completely surrounded by salt water or fresh water.
10. The machine assembly according to claim 7 , wherein the first machine component is a rotor shaft and the second machine component is a rotor hub.
11. A machine assembly comprising:
a first machine component including a first installation surface;
a second machine component connected with the first machine component and including a second installation surface facing the first installation surface;
a friction-increasing element disposed between the first installation surface and the second installation surface; and
a sealing material disposed within an intermediate space between the first installation surface and the second installation surface and circumferentially about an entire perimeter of the first and second machine components and the friction-increasing element, the sealing material being configured to seal the friction-increasing element from an external environment of the machine assembly and being formed from a liquid seal composition applied as a liquid into the intermediate space after assembly of the first and second machine components and then cured such that the liquid sealing material bonds to both installation surfaces and flows into any seal gaps in the assembly prior to curing.
12. The machine assembly according to claim 11 , wherein the friction-increasing element is a friction disc disposed between the first machine component and the second machine component.
13. The machine assembly according to claim 11 , wherein the friction-increasing element is a friction lacquer or a friction coating, the lacquer or coating being applied to the first installation surface and/or the second installation surface.
14. The machine assembly according to claim 11 , wherein the friction-increasing element includes hard material particles.
15. The machine assembly according to claim 14 , wherein the hard material particles include at least one of diamond, titanium boride, tungsten carbide and silicon carbide.
16. The machine assembly according to claim 14 , wherein the hard material particles are applied to at least one of the friction disc, the first installation surface and the second installation surface by a corrosion-protecting coating.
