ABSTRACT:
A method for monitoring mechanical power transmission systems is disclosed, wherein the power transmission system includes at least one power transmitting element, and which is characterized for a reliable and simple measurement of elongations on the power transmitting element by the following steps: First two substantially parallel planes are established on the unstressed power transmitting element, each plane being defined by at least three space coordinates or respectively measuring points on the power transmitting element. Then, the relative change in position of the two planes to one another is determined on the stressed power transmitting element. Finally, the determined relative change in position of the planes is correlated with the local elongation or compression on the power transmitting element. An apparatus for carrying out the method is likewise described.
