Safety device for dynamometric balancing machine - compares voltages proportional to bearing loads with voltages proportional to permissible loads

摘要

Voltages proportional to forces appearing in the bearings for the rotor to be balanced are generated by pickups and applied to an electric frame for evaluation. The unfiltered voltages are tapped off before the evaluation circuit and applied to peak value stores which are connected to comparators. The latter compare the voltages with voltages proportional to permissible loads. Two stores may be assigned to each signal voltage, one of each pair being for positive voltages and the other for negative voltages.
