Abstract

A machine arrangement, including at least one bearing ring, wherein a glass fiber is connected with the machine arrangement. To allow a proper measurement of stresses even at curved surfaces of the machine arrangement as it is typical in the case of bearing rings, the connection between the glass fiber and the machine arrangement is established by a metallic material which metal material is connected by material bonding with the machine arrangement as well as with the glass fiber.

First claim

The invention claimed is:

1. A machine arrangement, comprising at least one bearing ring;
a glass fiber connected with the machine arrangement,
wherein the connection between the glass fiber and the machine arrangement is established by a metallic material, wherein the metallic material is connected to each of the machine arrangement and the glass fiber by a material bonding, the metallic material encasing the glass fiber such that when viewing a cross section of the glass fiber the metallic material contacts and completely surrounds an outer surface of the glass fiber, the metallic material is materially bonded entirely around the outer surface of the glass fiber such that when viewing the cross section the metallic material is materially bonded to every circumferential location of the outer surface of the glass fiber, and wherein the metallic material is made of a single material composition such that the single material composition both encases the glass fiber and is the only material composition located between the glass fiber and a surface of the machine arrangement.

2. The machine arrangement according to claim 1 , wherein the material bonded connection between the metallic material and the machine arrangement is established by a welding process using the metallic material.

3. The machine arrangement according to claim 1 , wherein the material bonded connection between the metallic material and the glass fiber is established by one of a welding process or a melting process using the metallic material.

4. The machine arrangement according to claim 1 , wherein the metallic material is chromium (Cr).

5. The machine arrangement according to claim 1 , wherein the metallic material is nickel (Ni).

6. The machine arrangement according to claim 1 , wherein the metallic material is a metal alloy.

7. The machine arrangement according to claim 6 , wherein the metallic material is an alloy of chromium (Cr) and nickel (Ni).

8. The machine arrangement according to claim 1 , wherein the metallic material has a thickness measured in a direction perpendicular to a longitudinal axis of the glass fiber of at least 0.3 (zero point three) mm.

9. The machine arrangement according to claim 1 , wherein the glass fiber is arranged on a curved surface of the machine arrangement.

10. The machine arrangement according to claim 9 , wherein the curved surface of the machine arrangement is a cylindrical surface of the at least one bearing ring, and the single composition is the only material composition located between the glass fiber and the cylindrical surface.

11. The machine arrangement according to claim 1 wherein the metallic material has a thickness measured in a direction perpendicular to a longitudinal axis of the glass fiber of at least 0.5 mm.

12. A machine arrangement, comprising at least one bearing ring;
a glass fiber connected with the machine arrangement, the glass fiber being encased with a first metallic material such that when viewing a cross section of the glass fiber the first metallic material contacts and completely surrounds an outer surface of the glass fiber, the first metallic material is materially bonded entirely around the outer surface of the glass fiber such that when viewing the cross section the metallic material is materially bonded to every circumferential location of the outer surface of the glass fiber,
wherein the connection between the glass fiber and the machine arrangement is established by a second metallic material wherein the second metallic material is connected to each of the machine arrangement and the first metallic material by a material bonding, the second metallic material encasing the first metallic material such that when viewing the cross section the second metallic material contacts and completely surrounds a first metallic material outer surface, the second metallic material is materially bonded entirely around the first metallic material outer surface such that when viewing the cross section the second metallic material is materially bonded to every circumferential location of the first metallic material outer surface, and wherein there is no non-metallic material between the glass fiber and the at least one bearing ring.
