Abstract

The invention provides a space gear train stator blade adjusting device and a turbine engine. The space gear train stator blade adjusting device comprises an outer duct, an inner duct is arranged in the outer duct, a plurality of sets of stator blades are arranged between the inner duct and the outer duct, driving gears are installed on the multiple sets of stator blades, and the stator blades are driven by the driving gears. A supporting base is arranged above the driving gears, a hydraulic motor is installed on the supporting base, the output end of the hydraulic motor is connected with the driving gears, and a reversing gear is arranged between every two of the multiple sets of driving gears. According to the space gear train stator blade adjusting device and the turbine engine, two-way gear transmission is adopted, each stage of blade is driven by a set of gears in the forward direction and the reverse direction, the lateral rigidity of each stator blade is greatly improved, the transmission link of a transmission shaft is reduced, accumulation of errors is reduced, and the problem that stator blades of an existing aero-engine are stuck in the adjusting process and return difference caused by gaps and the like can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of blade adjustment of a turbine engine, in particular to a space train stator blade adjustment device and a turbine engine. Background technique [0002] A turbine engine is a form of engine that uses rotating parts to extract kinetic energy from the fluid passing through it. It is a type of internal combustion engine and is often used as an engine for aircraft and large ships or vehicles, while the stator blades are on the turbine engine. a component; [0003] In order to improve the stable working state of the aero-engine compressor, the general stator blades can be adjusted in angle, and the adjustment angle of each stage is different. The aero-engine adjustable stator blade adjustment device generally drives the connecting rod mechanism through the driving device to realize the adjustment of the blade. Angle adjustment is composed of actuators, four-bar linkages and linkage rings in the traditional str...
