EPICYCLIC GEAR MECHANISM OF TURBINE ENGINE AND ASSEMBLING METHOD OF TURBINE ENGINE AND EPICYCLIC GEAR MECHANISM

摘要

PROBLEM TO BE SOLVED: To provide the epicyclic gear train which carries out the rotational balance of an internal gear and a turbo fan shaft for a long period without a spline ring.

SOLUTION: A turbine engine includes the epicyclic gear train which has an internal gear of two component constitution. Each part of the internal gear has a flange extended to outside in the radial direction, and the flange is restrained axially to the turbo fan shaft by the bolt fixed in the circumferential direction along with the flange. A knife edge seal is fixed to the flange so as to collect the oil discharged from the internal gear to the gutter. Both internal gear and turbo fan shaft can be rotationally balanced.
