METHOD AND ARRANGEMENT FOR MONITORING GEARWHEELS DURING OPERATION

摘要

In a method for monitoring gearwheels during operation using at least one magneto-elastic sensor, which measures without making contact, changes in permeability when mechanical stresses are present in the gearwheel are recorded, wherein the positioning of the at least one magneto-elastic sensor (1) on the gearwheel to be monitored is such that said sensor measures the gearwheel in the region where high stresses occur and forces can be determined by measuring changes in permeability. The method can be used for contactless determination of data on gearwheels.
