Improving the Efficiency of Operation of Gas Turbine Plants Based on Turbo-Gear Units

During the operation of power plants based on gas turbine installations of ships, imbalances in the axes of the connected shafts of ship units inevitably occur, which have a negative impact on the reliability and performance of the main turbo-gear units. To compensate for these distortions, the design of a gear coupling with a combined longitudinal modification of the external and internal teeth is proposed, which due to the equal. The distribution of forces between all paired pairs of teeth is characterized by an increased load capacity of 2.19 times in comparison with traditional designs. When using these gear couplings, there is no need for re-entding of the increased rates of uncenters of the axes of the connected shafts of the main turbo-gear units with distortions of the axes of the connected shafts up to 5 center dot 10(-3) rads. Elimination of axle re-entding leads to an increase in the reliability of the vessel's operation and a decrease in the likelihood of emergency situations.
