摘要
A speed reducer has a sun gear for connection to a turbine of an engine and a planet carrier supporting a number of planetary gears meshing with the sun gear and with the ring gear fitted to the engine mounting. According to the present invention, the planet carrier has a first annular element having pairs of seats for pins on each of which rotates one of the planetary gears. A second annular element for connection to a compressor of the engine has a number of axial arms fitted inside respective cavities of the first annular element. An end of each axial arm is connected to a portion of the first annular element that is substantially equidistant between to the seats of each of the pairs of seats.
