Abstract: A rotor for a permanent magnet generator includes a rotor body extending between a first end and a second end, having a cylindrical bore and a plurality of flats on an outer peripheral surface. Permanent magnets are positioned at the flats. An outer ring surrounds the permanent magnets and defines an outer diameter. A ratio of the outer diameter to an axial length between the first and second ends is between 3.2 and 3.4. An integrated drive generator and a method are also disclosed.

Abstract: A pump sleeve for an inversion pump in an integrated drive generator has a pump sleeve body extending between a first end and a second end, the first end being at a location adjacent an enlarged endplate. The body extends to the second end with a generally cylindrical body portion having a bore of an inner diameter from the first end to the second end, and between the first and second ends for a distance. A ratio of the first distance to the inner diameter being is 1.8 and 2.0. In addition, an integrated drive generator is disclosed as is a method of replacing an accessory drive gear in an integrated drive generator.

Abstract: A trim ring gear for use in an integrated drive generator has a ring gear body extending between a first end and a second end. Outer gear teeth are formed on an outer surface, and inner gear teeth are formed on an inner surface. The outer tooth roll angle at A is between 16.0 and 17.5°, at B is between 17.5 and 190°, at C is between 22.0 and 23.5°, and at D is between 23.0 and 24.5°. The inner tooth roll angle at A is between 31.5 and 33.0°, at B is between 30.0 and 31.5°, at C is between 25.5 and 27.0°, and at D is between 24.0 and 25.5°. An integrated drive generator, and a method of replacing the trim ring gear are also disclosed and claimed.
