Abstract

The invention discloses a reducer case which comprises a hollow drum-shaped case shell, wherein one end of the case shell is connected with an accessory case of an engine, and the other end of the case shell is connected with an inner fairing cover of an air inlet channel of the engine; a plurality of mounting holes used for mounting a torsion detecting mechanism are formed in an end part of the case shell; a front inner chamber, a middle inner chamber and a rear inner chamber which are communicated with each other are successively arranged in the case shell along an axial direction thereof; the rear inner chamber is used for mounting a speed reduction device; a first bearing sleeve is arranged in the front inner chamber; a second bearing sleeve is arranged in the middle inner chamber; an oil-separating lining sleeve is arranged between the first bearing sleeve and the second bearing sleeve; a plurality of channels which are used for connecting a distance-variable oil path system on the exterior of the reducer case and a main lubricating oil system are arranged on the oil-separating lining sleeve; pressure lubricating oil in the distance-variable oil path system passes through the channels and then enters an engine output shaft system and a propeller system; and the lubricating oil in the main lubricating oil system passes through the channels and then enters the case shell so as to lubricate the parts arranged in the case shell.

Description

technical field [0001] The invention relates to the field of aero-engines, in particular to a reducer case. Background technique [0002] Aeroengine reducer requirements are suitable for different layouts or specific purposes. A certain type of turboprop engine reducer transmits the output power of the engine to the propeller, reduces the speed of the propeller, and makes the propeller at the most favorable operating speed; in addition, there are It is equipped with a torque measuring mechanism, a negative tension feathering sensor system, and a variable-pitch oil circuit system for propeller system manipulation; in addition, the reducer component is installed at the front end of the compressor, and the shape of the reducer should ensure that the air can move freely. Flow into the compressor smoothly and make the inlet air have a uniform velocity field. The case of the reducer is the shell of the reducer, and it is one of the important components of the reducer. It must bea...
