Abstract

See full text

A gear assembly for a gas turbine engine has an input gear adapted to be secured to a turbine shaft. An output gear is adapted to be secured to a compressor shaft, the input gear and the output gear having the same number of teeth. A pair of idler gear shafts is provided, each said idler gear shaft having a first stage gear meshed with the input gear to be driven by the turbine shaft at a first stage of speed change. A second stage gear is axially spaced from the first stage gear and rotates with the first stage gear. The second stage gear is meshed with the output gear to drive the compressor shaft at a second stage of speed change. Landmarks are provided for aligning the gears during assembly in a desired orientation.
