  • Ring gear for an epicyclic reduction gear
    Patent number: 10688608
    Abstract: A method for aligning toothing in an assembly of two half-ring gears is provided: an angular positioning pin is provided which is to be received in respective holes of the half-ring gears; the holes are drilled on the first half-ring gear such that the first hole has a first cross-section that is smaller than the final cross-section thereof; the angles between the teeth are compared between the two half-ring gears, and an angular difference between said angles of the half-ring gears is deduced therefrom; the first hole is redrilled to the final cross-section, while the centre of the hole is angularly shifted by the value of the angular difference; the pin is engaged in the holes, and the half-ring gears are then assembled using an interference fit.
