SOLAR POWER FOR A MECHANICAL GEARBOX ON AN AIRCRAFT TURBOMACHINE

Abstract

Solar element (11) for a mechanical gearbox (10) of an aircraft turbomachine (1), the gearbox (10) having an annular shape around an axis (X) and comprising internal coupling splines (7a) on its inner periphery, and at least one meshing tooth (11x) on its outer periphery, characterized in that it is formed by the assembly of two half-solars (11a, 11b), a first half-solar element (11a) comprising a first row of teeth (11x1) of the toothing (11x), and a second half-solar element (11b) comprising a second row of teeth (11x2) of the toothing (11x) as well as the internal splines (7a).
