A Study on the On-line Monitoring Methods of the Bearing Load in Large Turbine Generators

This paper proposes the meaning of the on-line monitoring bearimg load in large turbine generators,and analyses various measuring methods of the bearing load. It is pointed out that the supporting force method is a kind of better method for monitoring the bearing load,which is a direct way measuring bearing load with force sensors installed in between bearing and bearing bases. This paper considers that the key technology of the Supporting force method includes the adaptability of the structure and the function, long-term stability and reliability. It studies also the feasibility of this way for on-line monitoring bearing load of turbine generators.The researching results state clearly that the supporting force method is necessary and feasible.
