Abstract

The invention discloses an inner ring structure of an adjustable stator blade of an engine fan, and relates to the technical field of gas compressors. The inner ring structure of the adjustable stator blade of the engine fan is used for positioning the adjustable stator blade (3); the inner ring structure of the adjustable stator blade of the engine fan comprises inner ring front sections (4), an inner ring rear section (5) and a positioning block (6), wherein the positioning block (6) is provided with a positioning hole (61); the positioning hole (61) is used for mounting a rotary shaft of the adjustable stator blade (3); a plurality of clamping slots (51) are uniformly distributed at the circumference of the inner ring rear section (5); the clamping slots (51) are used for mounting the positioning block (6); and the plurality of inner ring front sections (4) are fixedly connected to the inner ring rear section (5) for fixing the positioning block (6). The inner ring structure has the beneficial effects that: the inner ring front sections can be directly mounted without the needs of rotating the adjustable stator blade, so that the mounting is simple and convenient, and the working efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of engines, in particular to an inner ring structure of adjustable stator blades of an engine fan. Background technique [0002] The inner ring of the adjustable stator blade of the fan of the aircraft engine is mostly used such as figure 1 As shown in the structure, the adjustable stator blade 3 is connected to the radial cylindrical hole of the front section of the inner ring and the rear section of the inner ring through the blade adjustable rotating shaft (the contact surface between the front section of the inner ring and the rear section of the inner ring is axially positioned with The adjustable rotating shaft of the stator blade is on the same axial section, and the radial cylindrical holes in the front section of the inner ring and the rear section of the inner ring are semi-cylindrical holes centered on the contact surface). Because the outer contour of the inner ring is inclined, the front part of the ...
