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 glass material. The glass 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 or being at least one bearing ring formed of a metal, wherein a glass fiber is connected with the machine arrangement,
wherein the connection between the glass fiber and the machine arrangement is established by a glass material wherein the glass material is connected by material bonding with the at least one bearing ring formed of the metal as well as with the glass fiber, the glass material being the only material between the glass fiber and the at least one bearing ring such that there is no non-glass material between the glass fiber and the at least one bearing ring,
wherein the glass fiber is connected with the machine arrangement by encasing the whole circumference of the glass fiber with the glass material along at least a part of the longitudinal axis of the glass fiber,
and wherein the glass fiber is not located within a groove of the at least one bearing ring such that the glass fiber is spaced radially from an outer cylindrical surface of the at least one bearing ring.

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

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

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

5. The machine arrangement according to claim 1 , wherein the glass material is materially bonded to the outer cylindrical surface of the at least one bearing ring.

6. The machine arrangement according to claim 1 , wherein the glass material has a thickness measured in the direction perpendicular to the longitudinal axis of the glass fiber of at least 0.5 (zero point five) mm.
