Abstract:
1. A measuring device for detecting stresses of a bearing arrangement wherein the stresses are measured using elastic shape changes, the measuring device comprising at least one light source which directs light into at least one light passage, which is formed in at least one web on a supporting ring, the web extending radially from the bearing arrangement, and having at least one light sensor for measuring the amount of at least one part of the light which passes through the light passage and strikes the light sensor changed by means of the elastic shape changes of the light passage, and the light passage being formed, in a manner which is spatially separated from the bearing arrangement, in an at least partially elastically yielding support which is coupled to the bearing arrangement, and the light passage being deformed elastically by the stresses on the bearing arrangement.
