LONG LIFE EPICYCLIC GEARS

The gas turbine is a fast-running engine that is unusually compact and light-weight in comparison with other types of internal combustion engines. Double reduction gears are needed, in most cases, to reduce turbine output speed to the synchronous speeds of 60- and 50-Hz alternating current generators or other driven equipment operating at speeds in the 1,000 to 3,600 rpm range. In recent years, great strides have been made in the development of compact, lightweight epicyclic gear drives for industrial gas turbine applications. The epicyclic gear design complements the physical characteristics of the gas turbine so that a power plant package of favorable overall dimensions and weight can be achieved. Though somewhat more complex than the more commonly used pinion/gear arrangements, the epicyclic gear can, with appropriate design and quality control, have the same long-life characteristics that the much larger pinion/gear drives have achieved.
