Abstract
The invention relates to a measuring device for measuring changes in the position of the edge of a body of a component. Said measuring device contains a sensor which reacts to the changes, a light source, a measuring edge fixed in relation to the edge of the body, and a light emitted from the light source. From the change in position, information about the deformation caused by a force F (for example, in the case of bearings) can be obtained, a weight or an imbalance can be determined, and joints and press fits can be monitored. The measurement is carried out by reflection or transmission, preferably using optical waveguides.
Claims13
A measuring device for measuring changes in at least one position of at least one body edge of a component, the measuring device comprising:
- at least one sensor reacting to the changes, wherein the measuring device has at least one light source, at least one measuring edge that is fixed in relation to the body edge, and at least one light emanating from the light source, it being possible for the measuring edge to vary its position by comparison with the light at least from an initial position, and a portion of the light that has been changed in size by changes in the position by comparison with the initial position of the measuring edge(s) strikes the sensor without impediment.
