Method for monitoring mechanical wear
First Claim
1. A method for monitoring mechanical wear caused by a first component (1) on a second component (2), wherein the first component (1) is movable relative to the stationary second component (2) and wherein the first and second components (1,2) are at least at times in mechanical contact with a another, the method comprising the steps of:
- arranging at least one sensor head (4) in a wear area to be monitored of the second component (2);
connecting a light guide (10) to the at least one sensor head (4), wherein the light guide (10) has a forward end with a metal coating (11);
guiding a measuring signal in the form of light into the light guide (10) and reflecting the light on the metal coating (11);
causing the metal coating (11) to be mechanically worn by the first component (1) upon reaching a predetermined wear limit;
measuring an intensity of the light reflected on the metal coating (11); and
dectecting a drop in the Intensity of the light reflected on the metal coating (11) when the predetermined wear limit is reached.

Abstract
In a method for monitoring mechanical wear caused by a first component on a second component, wherein the first and second components are movable relative to one another and wherein the first and second component are at least at times in mechanical contact with one another, at least one sensor head is arranged in a wear area to be monitored of the second component. The at least one sensor head is mechanically worn by the first component upon reaching a predetermined wear limit. When the at least one sensor head is mechanically worn, a measuring signal is generated by the at least one sensor head or a change of a measuring signal, produced by the at least one sensor head prior to having been mechanically worn, is detected.
