An Improved Method To Determine The Scoring Resistance Of Turbomachinery Gearing.
The petrochemical and utility industries are experiencing a growing demand for high power turbogear units for use in large gas turbine compressor and generator drives. A growing number of high speed gears with ratings up to 70,000 kW are already in service. For such gears, the failure mode of scoring can become the limiting constraint. The validity of an analytical method to predict scoring resistance is, therefore, becoming increasingly important. A simplified calculation procedure, that is suitable for high power, high speed gearing, and is based on the Winter and Michaelis integral temperature method, is presented.
