Problems solved by technology

The principle of this kind of fine-tuning mechanism is also feasible, but there are many reliability problems and disadvantages in use, mainly in: fine-tuning operation has out-of-step, overshoot, swing and other phenomena, mechanism failures occur frequently, and the structure occupies a large space and is stable. Sexuality and reliability are not high
The reason is that the structure is complex, the transmission path is long, and the electromechanical handover is complicated.

Abstract

The invention relates to the technical field of mechanical structure transmission, and specifically discloses a fine-tuning mechanism, which includes: an operating handle, a transmission shaft, a damping structure, a one-way transmission mechanism, a fine-tuning knob and a rotation angle acquisition module, and one end of the operating handle and the transmission shaft connection, the damping structure is set on the transmission shaft, the one-way transmission mechanism is connected with the damping structure, the fine-tuning knob is set on the one-way transmission mechanism, the rotation angle acquisition module is set on the transmission shaft, and the fine-tuning knob can drive the one-way transmission mechanism when rotating Rotation, the rotation of the one-way transmission mechanism can drive the rotation of the transmission shaft through the rotation of the damping structure, the rotation of the transmission shaft can drive the rotation of the operating handle, and the rotation angle acquisition module is used for communication connection with the controller. The invention also discloses an accelerator control system. The fine-tuning mechanism provided by the invention has the advantages of higher stability and short transmission path.

Description

technical field [0001] The invention relates to the technical field of mechanical structure transmission, in particular to a fine-tuning mechanism and an accelerator control system comprising the fine-tuning mechanism. Background technique [0002] Aeroengines have the characteristics of high power and quick response. When the fuel supply exceeds the predetermined range, structural damage is prone to occur, resulting in very large losses. Therefore, the test throttle control system is required during the test run of the aero-engine, which has very high reliability and accuracy. In the throttle control system of the aero-engine test bench, it is necessary to add a fine-tuning device to the control mechanism to accurately control the fuel supply, so as to accurately and effectively control the working state of the engine. [0003] The fine-tuning mechanism in the previous throttle control system is realized by the combination of gear set, damping structure, stepping motor and...
